Abstract
OBJECTIVES External environmental heat exposure during gestation impacts the physiology of human development in utero, but evidence for these impacts has not yet been explored in dentition. We examined deciduous teeth for fluctuating asymmetry (FA), a measure of developmental instability, together with gestational environmental temperature data drawn from historical weather statistics. MATERIALS AND METHODS We measured dental casts from the longitudinal Burlington Growth Study, representing 172 participants (ages 3-6 years) with health records. FA was calculated from crown dimensions and intercuspal distances that develop during gestation. Multiple regression separated by sex (nfemale = 81) examined the effects of mean temperatures in each trimester, controlling for birth year. RESULTS In females, increased temperatures during the first trimester are significantly associated with an increase in FA (p = 0.03), specifically during the second and third prenatal months (p = 0.03). There is no relationship between temperature and FA for either sex in the second or third trimesters, when enamel is formed. DISCUSSION Dental instability may be sensitive to temperature in the first trimester in females during the scaffolding of crown shape and size in the earliest stages of tooth formation. Sexual dimorphism in growth investment strategies may explain the differences in results between males and females. Using enduring dental characteristics, these results advance our understanding of the effects of temperature on fetal physiology within a discrete period.

Abstract
OBJECTIVES (i) To identify suitable strategies and opportunities to embed Environmental Sustainability (ES) within an existing Oral Health Professional (OHP) curriculum through a series of focus groups with students and academic staff and (ii) To create high-level evidence-based and subject-specific ES content through an approach grounded in evidence and collaboration with key stakeholders in OHP education. METHODS Focus groups were used to explore academic staff and student views on appropriate teaching and assessment methods for ES. Content statements were developed from an extensive literature search, mapped to curriculum subjects, and validated through consultation with students, discipline-experts and education-experts. RESULTS Five themes were identified from the focus groups: ES transcends all disciplines of dentistry and oral healthcare; baseline knowledge transmission with relevant practical application; viewing and modifying existing teaching and assessment events through a different lens; normalising the topic of ES to support attitude and behaviour change and safeguarding against misinformation and disinformation. Forty-four content statements were developed and mapped to nineteen curriculum subjects. CONCLUSIONS This study identifies for the first time a comprehensive strategy for the inclusion and delivery of ES (method and content) in the curriculum. A novel method to define and map curriculum content has been explored and validated using a range of complementary methodologies. A comprehensive and robust list of evidence-based and subject-specific educational content statements have been defined in the field of Environmental Sustainability in dentistry and oral healthcare. CLINICAL SIGNIFICANCE Oral healthcare has a significant environmental impact, the key to all mitigation strategies is educating the profession at all levels.

Implementation of a nursing oral health care protocol in a university teaching hospital: A cluster-randomized stepped-wedge design. Int J Dent Hyg 2024; 22:661-671. [PMID: 37722075 DOI: 10.1111/idh.12748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 01/24/2023] [Accepted: 07/30/2023] [Indexed: 09/20/2023]
Abstract
INTRODUCTION Providing oral care is an essential part of basic nursing care but receives little priority in daily practice, with a risk of adverse events. Also, nurses report many barriers to adequate provision of oral care, such as time restraints, insufficient materials, fear of causing pain, lack of knowledge and a negative attitude towards providing oral care. METHODS We performed a cluster-randomized, stepped-wedge study to explore the effect of the the implementation of a new nursing evidence-based oral care protocol on nurses' knowledge, attitude and protocol adherence. The study population included both nursing students, graduated nurses and patients in selected wards. The implementation strategy included oral and written information, instruction videos and reminders. Nurses' knowledge and attitude towards oral care were assessed at baseline and after the implementation of the protocol with a validated 47-item questionnaire with a score range of 0-100. Secondarily, nurses' protocol adherence to teeth brushing, measured in Activities of Daily Living (ADL) dependent patients, was evaluated. The Standards for Reporting Implementation Studies (StaRI) Statement was used. RESULTS At baseline, the questionnaire was completed by 226 nurses; after implementation by 283. Knowledge had significantly improved from 68.8 to 72.3. Nurses' attitude improved not significantly. Protocol adherence was assessed in 73 ADL-dependent patients at baseline, in 51 after implementation. Adherence to teeth brushing significantly decreased in patients with permanent teeth. Also, adherence to both teeth brushing and usage of soap decreased in patients with (partial) dentures. CONCLUSION Nurses' knowledge and attitude of oral care increased somewhat after the implementation of a new nursing evidence-based protocol. After implementation, there was an unexplained decreased adherence to oral care in ADL-dependent patients.

Efficacy and safety of a new heterologous fibrin biopolymer on socket bone healing after tooth extraction: An experimental pre-clinical study. J Clin Periodontol 2024; 51:1017-1033. [PMID: 38685818 DOI: 10.1111/jcpe.13992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 03/13/2024] [Accepted: 04/12/2024] [Indexed: 05/02/2024]
Abstract
AIM To assess the efficacy of heterologous fibrin biopolymer (HFB) in promoting alveolar bone healing after tooth extraction in rats. MATERIALS AND METHODS The upper right incisors of 48 Wistar rats were extracted. Toothless sockets were filled with HFB (HFBG, n = 24) or blood clot (BCG, n = 24). The tooth extraction sites were subjected to micro-computed tomography (micro-CT), histological, histomorphometric and immunohistochemical (for Runt-related transcription factor 2/Runx2 and tartrate-resistant acid phosphatase/TRAP) analyses on days 0, 7, 14 and 42 after extraction. RESULTS Socket volume remained similar between days 0 and 14 (69 ± 5.4 mm3), except in the BCG on day 14, when it was 10% lower (p = .043). Although the number of Runx2+ osteoblasts was high and similar in both groups (34 × 102 cells/mm2), the HFBG showed lower inflammatory process and osteoclast activity than BCG at 7 days. On day 14, the number of Runx2+ osteoblasts remained high and similar to the previous period in both groups. However, osteoclast activity increased. This increase was 55% lower in the HFBG than BCG. In the BCG, the presence of an inflammatory process and larger and numerous osteoclasts on day 14 led to resorption of the alveolar bone ridge and newly formed bone. On day 42, numbers of Runx2+ osteoblast and TRAP+ osteoclasts decreased dramatically in both groups. Although the BCG exhibited a more mature cortical bone formation, it exhibited a higher socket reduction (28.3 ± 6.67%) and smaller bone volume (37 ± 5.8 mm3) compared with HFBG (socket reduction of 14.8 ± 7.14% and total bone volume of 46 ± 5.4 mm3). CONCLUSIONS HFB effectively suppresses osteoclast activity and reduces alveolar bone resorption compared with blood clot, thus preventing three-dimensional bone loss, particularly during the early healing period. HFB emerges as a promising biopharmaceutical material for enhancing healing processes after tooth extraction.

Abstract
OBJECTIVE This study aims to explore dentists' knowledge, attitudes, and perceptions regarding antibiotic use. METHODS We conducted a systematic review of dentists' knowledge, attitudes and perceptions regarding antibiotic use, by searching the MEDLINE, EMBASE and Web of Science for all original paper published from January 1990 to July 2023, in accordance with the Preferred Reporting Items for systematic Reviews and Meta-analyses (PRISMA 2020) guidelines. RESULTS The review included 37 papers, (7 qualitative and 30 quantitative studies). Modifiable factors (knowledge, attitudes) were reported as being associated with antibiotic prescribing by dentists which were cited in 30 of the 37. These attitudes most frequently identified by dentists were: complacency (22/29); lack of trust (16/29); the need to postpone the dental procedure (17/29); and fear (8/29). Gaps in knowledge were also identified (15/29). Only one of the included articles quantified the influence between the reported modifiable factors and antibiotic prescribing. CONCLUSIONS The review emphasizes that dentists' antibiotic prescribing is predominantly influenced by modifiable factors. This insight informs the potential for targeted interventions to curtail inappropriate antibiotic use, contributing to global efforts in reducing antibiotic resistance. The protocol of this systematic review can be found in PROSPERO under registration no. CRD42021253937.

Abstract
PURPOSE Sodium hypochlorite (NaOCl) is considered as the reference irrigation solution in endodontics. However, NaOCl-related accidents may occur, and non-dentist health professionals might under-recognize this rare adverse effect although it is potentially severe, with possible medical and aesthetic sequelae. We performed a literature review to provide to non-dentist healthcare professionals a large picture of symptoms, management and potential consequences of NaOCl accidents. METHODS We queried PubMed and the French Pharmacovigilance database and retrieved 76 cases for analysis (70 from 57 published articles, and six from the database). RESULTS The analysis showed that patients were mostly women (79%), aged around of 42 years, undergoing upper jawbone (74%) endodontic procedure. NaOCl concentration ranged from 1% to 10%, with 0.5 to 30 mL injected. Most cases (86%) corresponded to an accidental extrusion beyond the root apex to the periapical tissues, followed by tissular injection by error (8%) and extrusion into the maxillary sinus (3%). Local symptoms always occurred within 24 h, mostly pain (99%), edema (89%) and/or ecchymosis (61%). Complications were mainly neurological (29%), necrotic (22%) and cutaneous (9%). Most of patients (76%) fully recovered after medical management but 18 (24%) required surgical management. CONCLUSION Any healthcare professional should be aware of the classical symptomatic triad of NaOCl accident with sudden pain, haemorrhage/ecchymosis and swelling, to start or recommend adequate management. Patients should be reassured, but a close follow-up is necessary to avoid delayed complication.

Abstract
OBJECTIVES The objective of this systematic review was to assess the efficacy of topical applications containing surface pre-reacted glass-ionomer filler on dental hard tissues. DATA SOURCES A comprehensive literature search was conducted in PubMed, MEDLINE, Embase, Scopus, ClinicalTrials.gov, Lilacs and Cochrane Central Register of Controlled Trials (until 15.08.2022). Google and Open Grey were used to search for grey literature and handsearching was conducted. STUDY SELECTION Clinical and in vitro studies conducted on human adult teeth were considered eligible without date and language restrictions. The electronic database generated 2,488 results. In total, 227 studies were found to be relevant from which 71 duplicates were removed. Title and abstract screening were then conducted, and a total of 33 studies met the inclusion criteria were assessed for full text screening. Two authors concluded that 11 studies satisfied the eligibility criteria. In vitro studies were evaluated using an accepted quality assessment tool for dental studies. Cochrane risk of bias tool was used for quality assessment of clinical randomised studies, whilst ROBINS-I tool was used for non-randomised studies. RESULTS Nine in vitro and only two non-randomised clinical trials were reported to meet the eligibility criteria. Results were grouped and analysed separately according to the study design. Different modes of surface pre-reacted glass-ionomer filler delivery were reported in the included studies. Three studies tested the effect of surface pre-reacted glass-ionomer filler containing toothpastes, whilst three studies investigated the effect of polishing pastes with surface pre-reacted glass-ionomer filler, three studies used eluates as surface pre-reacted glass-ionomer filler delivery method and two studies reported the effect of the coatings. The effect of those vehicles was tested on enamel, dentine or oral biofilm. Each study was analysed individually, and heterogeneity was detected among in vitro and clinical studies. Half of the in vitro studies were medium risk, whilst three were low and two studies presented with high risk. In clinical trials, outcome, confounding, selection biases were reported. Meta-analysis was therefore unable to be carried out. CONCLUSION Regardless of the mode of delivery and type of studies, all included studies demonstrated the efficacy of surface pre-reacted glass-ionomer filler containing topical applications to inhibit demineralisation of dental hard tissues at a dose dependant manner. Antimicrobial properties towards cariogenic species were also reported. CLINICAL SIGNIFICANCE Surface pre-reacted glass-ionomer filler containing topical applications may serve as potential caries preventive and cariostatic tools. The systematic review registered in PROSPERO, International prospective register of systematic reviews, No. CRD42022347130.

Abstract
OBJECTIVES Limited literature addresses the long-term success of complete pulpotomy in permanent molars with signs of irreversible pulpitis in young patients. The aim of this observational study was to prospectively evaluate the long-term outcomes of complete pulpotomy using mineral trioxide aggregate (MTA) over an average period exceeding 11 years. METHODS Out of 27 molars displaying signs suggestive of irreversible pulpitis which underwent MTA pulpotomy, 24 molars were followed-up for a mean duration of 11.0 ± 2.2 years (range 8.2 to 14.8 years). Clinical and radiographic assessments were periodically conducted, tailored to each patient's specific circumstances. Treatment failure criteria included clinical signs and symptoms and radiographic evidence suggesting a lack of pulpal or periapical healing. RESULTS 83 % of molars had signs and symptoms of symptomatic irreversible pulpitis, with 83 % displaying apical periodontitis. Clinically and radiographically, all pulpotomies (100 %) were considered successful. A hard tissue barrier was observed in 71 % of teeth, and continued root maturation was evident in all molars with open apices. Complete pulp canal obliteration (PCO) was present in 21 % of the molars. All radiographic apical radiolucencies completely resolved. CONCLUSIONS This study demonstrates a 100 % success rate over an average 11-year follow-up for complete pulpotomy in managing permanent molars with signs and symptoms of irreversible pulpitis in young patients. It offers evidence for its long-term efficacy in promoting healing of pulp and periapical tissues. CLINICAL SIGNIFICANCE This study showed high long-term success for complete pulpotomy in young permanent molars with irreversible pulpitis, with clinical and radiographic success over 11 years. Despite initial symptoms of pulpitis and apical periodontitis, the treatment resulted in tissue healing, root maturation, and resolution of periapical radiolucencies, suggesting it as an alternative to root canal therapy.

Abstract
INTRODUCTION Continuing professional development is a lifelong learning process. One pedagogical approach that can be used is active learning. Flipped classroom is a method that has been shown to improve deeper conceptual understanding. In an online setting, the method saves travel, time, and costs. To our knowledge, flipped classroom is rarely used in continuing professional education. This study in general dentistry explored experiences of an online flipped classroom course in continuing professional development. MATERIALS AND METHODS Fifteen dental hygienists, clinically active in general dental care, were interviewed. They were recruited from an online course on the latest classification system for periodontal diseases. The course had been conducted using an active learning and flipped classroom model. The interviews were semi-structured. Data were extracted using qualitative content analysis. RESULTS The experiences of the dental hygienists could be summarized in three themes: Stimulation of knowledge gain through self-paced studies, The ease of virtual networking among colleagues, and Fostering of direct practical application through collaboration. CONCLUSION New and emerging communication technology seems to open new possibilities for continuing professional development in general dentistry. Study participants felt that, in an online environment, mixing asynchronous and synchronous communication in a flipped classroom model facilitated learning in continuing professional development. Online active learning seems to work well in continuous professional development in general dentistry. After the course, the participating dental hygienists stated that they were able to use their new knowledge clinically and felt confident doing so.

[PMID: 38622868 DOI: 10.1111/eje.13011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 12/20/2022] [Accepted: 03/18/2024] [Indexed: 04/17/2024]
Abstract
INTRODUCTION This study aimed to develop a module that incorporates hands-on and reflective feedback in teaching dental materials science and subsequently analyse undergraduate dental students' learning experiences with the module. MATERIALS AND METHODS The module was developed based on the ADDIE (Analyse, Design, Develop, Implement, Evaluate) model. First, a need analysis was conducted, followed by designing the module to address the needs. Next, the module sought experts' feedback and was piloted. The revised module was implemented among all second-year undergraduate dental students. Finally, a validated questionnaire (5-point Likert scale items and open-ended questions) was used to evaluate students' learning experiences. The questionnaire Likert scale items were analysed descriptively, whereas open-ended responses were analysed using content analysis. RESULTS In the analysis phase, a slight misalignment in cognitive competency levels was observed, alongside a need for the inclusion of more hands-on activities. In the design phase, learning objectives and resources were listed. Subsequently, a module consisting of four teaching sessions (3 h each) was developed, and the pilot test showed favourable feedback. The module was then implemented in small groups of 10-12 students. In the evaluation phase, 72 students (97% response rate) completed the questionnaire. The majority of students agreed with all items, with mean scores ranging from 4.53 to 4.72. Open-ended responses highlighted that hands-on activities and reflective feedback sessions were useful. CONCLUSION Students demonstrated positive learning experiences after participating in the module, advocating for dental educators to consider more hands-on activities and reflective feedback sessions in teaching dental materials science.

Creation and evaluation of an educational escape room for preclinical training on 3D printing in dentistry. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2024; 28:707-717. [PMID: 38419306 DOI: 10.1111/eje.12999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 12/30/2023] [Accepted: 02/04/2024] [Indexed: 03/02/2024]
Abstract
INTRODUCTION The benefit of pedagogical escape rooms for dental students' stimulation, interest and knowledge strengthening has been suggested by several studies. However, in previous studies, only a few students were evaluated. This study aims to confirm the purpose of this innovative pedagogical tool in terms of learning consolidation and team building from students' perceptions. We directly incorporated an educational escape game into the fundamental academic formation as a practical-work course for fifth-year dental students. MATERIALS AND METHODS The present escape game focused on 3D printing, whose implementation fit the different steps of an escape game well. This study was conducted in March 2022. All fifth-year dental students (n = 212) were divided into 5-6 student groups to match the conditions of an escape game. Before entering the room, each student had to complete a cross-sectional knowledge true/false test of 8 questions to assess their general level. Additionally, an 18-question appreciation survey was completed when leaving the room. RESULTS The students perceived the 3D-printing escape game to be relevant and especially expressed the benefit of being part of a team to exchange and build knowledge. These results suggest knowledge strengthening. The instructional benefit of this process seemed to exceed its mere fun and appealing aspect. CONCLUSION Our results with a large number of students showed that, from the students' perception, the educational escape game significantly improved knowledge and team-building. It created a supportive learning environment and increased students' motivation. It can provide a fun and effective way to diversify instruction.

Abstract
OBJECTIVES To investigate the role of high-resolution ultrasound (HR-US) in the initial and differential diagnosis of the Odontogenic Cutaneous Sinus Tract (OCST) in a multicentric setting. METHODS Skin HR-US examinations of OCSTs performed between January 2019 and June 2023 at different Institutions were retrospectively reviewed. Epidemiological and clinical data (age, gender, location of the skin lesion, causative tooth, and the clinical suspicion) as well as HR-US imaging findings (morphology and length of the sinus tract, Doppler signal, and cortical bone interruption of maxilla or mandible) were collected. US examinations were performed by expert radiologists using a high-performance US scanner, employing a high-frequency linear probe (15 MHz or higher frequencies). In only one patient the HR-US exam was integrated with strain elastography (SE). RESULTS Sixteen patients were enrolled with a median age of 37.6 years (range 16-70 years). The most frequent clinical suspicion was epidermal cyst, while OCST was suspected in only two cases. In all cases, HR-US depicted the sinus tract as a nodular, triangular or "champignon-shaped" lesion in the subcutaneous layer, which continued with a slightly tortuous band structure, up to the focally interrupted cortical bone plate. Furthermore, color Doppler evaluation showed color signals around and/or within the lesion, expression of inflammation. On SE, the sinus tract showed a hard pattern, due to fibrous and granulomatous tissue. CONCLUSIONS HR-US, thanks to its high spatial resolution, allows the evaluation of OCST, and play a crucial diagnostic role, mainly when the clinical suspicious is different.

Abstract
INTRODUCTION During child dental treatment, different behavior management techniques (BMTs) are applied and it is important to understand the possible discomfort in the operator. OBJECTIVE The present systematic review aimed to evaluate the acceptability of dental students and professionals concerning BMTs applied with paediatric dentistry patients. MATERIALS AND METHODS A systematic search was conducted, following the PEOS strategy: Population (P) - dental students/professionals (S); Exposure (E) - BMTs preconized by the American Academy of Paediatric Dentistry, Outcome (O) - proportion of BMT acceptance; and Study design (S) - observational studies based on data from PubMed, Scopus, Web of Science, BVS (Lilacs/BBO), Cochrane, and Open Grey databases up to September 2021. The eligible studies were submitted to data extraction and to the evaluation of methodological quality, using the Joanna Briggs Institute Critical Appraisal Tool. The certainty of evidence was evaluated by GRADE. RESULTS The search retrieved 710 articles; a total of 21 fulfilled the eligibility criteria and were used for qualitative analysis. Among the undergraduate students and dentists, the most accepted techniques were tell-show-do and positive reinforcement, while paediatric dentists preferred the tell-show-do technique and dental professionals with graduate degrees preferred sedation using nitrous oxide and positive reinforcement. The least accepted technique was protective stabilization. Seven students presented a low risk for bias, while 14 presented a high risk. The certainty of evidence was classified as very low. CONCLUSION Although the basis of available certainty of evidence is scarce and with a considerable risk for bias, it is still possible to conclude that the more accepted techniques were based on communication.

Abstract
OBJECTIVE This cross-sectional study aims to examine the effect of marijuana-smoking on dental caries experience and to explore the potential combined effects of tobacco and marijuana cigarette-smoking. METHODS We used data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES). We examined demographics, tobacco- and marijuana-smoking, dental examination, and dietary intake. Caries was measured as decayed, missing, filled teeth (DMFT). Data analysis included univariate, bivariate analyses, and linear regression model (LRM) to examine the association between marijuana-smoking and DMFT. RESULTS Mean DMFT score was lowest for nonsmokers (8.72) and highest for current marijuana smokers (9.87) (P < .0001); however, LRM results revealed that marijuana-smoking was not associated with caries. Adjusted DMFT was the highest for current tobacco and former marijuana smokers (β estimate = 1.18; 95% CI, -0.27 to 2.62), but the relationship was not statistically significant. CONCLUSIONS After controlling for potential confounders, there was no significant association between marijuana-smoking and dental caries experience. However, when marijuana and tobacco were smoked concurrently, there was a notable increase in DMFT, although the difference was not statistically significant. Future research should be directed towards exploring the effects of different forms of marijuana consumption, such as edibles and drinkables, on caries development. Health promotion programmes should be aimed at educating the public regarding the combined health impacts of smoking both marijuana and tobacco, considering the potential heightened caries risk.

Abstract
OBJECTIVE To determine differences in post-treatment QoL across treatment settings in patients receiving adjuvant radiation therapy for head and neck squamous cell carcinoma (HNSCC). METHODS This was a prospective observational cohort study of patients with HNSCC initially evaluated in a head and neck surgical oncologic and reconstructive clinic at an academic medical center (AMC). Participants were enrolled prior to treatment in a prospective registry collecting demographic, social, and clinical data. Physical and social-emotional QoL (phys-QoL and soc-QoL, respectively) was measured using the University of Washington-QoL questionnaire at pre-treatment and post-treatment visits. RESULTS A cohort of 177 patients, primarily male and White with an average age of 61.2 ± 11.2 years, met inclusion criteria. Most patients presented with oral cavity tumors (n = 132, 74.6%), had non-HPV-mediated disease (n = 97, 61.8%), and were classified as Stage IVa (n = 72, 42.8%). After controlling for covariates, patients treated at community medical centers (CMCs) reported a 7.15-point lower phys-QoL compared with those treated at AMCs (95% CI: -13.96 to -0.35, p = 0.040) up to 12 months post-treatment. Additionally, patients who were treated at CMCs had a 5.77-point (-11.86-0.31, p = 0.063) lower soc-QoL score compared with those treated at an AMC, which was not statistically significant. CONCLUSION This study revealed that HNSCC patients treated with radiation at AMCs reported significantly greater phys-QoL in their first-year post-treatment compared to those treated at CMCs, but soc-QoL did not differ significantly. Further observational studies are needed to explore potential factors, including treatment planning and cancer resource engagement, behind disparities between AMCs and CMCs.

Abstract
OBJECTIVES The present study aimed to evaluate the effectiveness of bioactive glass (BAG) in preventing dental erosion in primary teeth. METHODS Enamel and dentin specimens (2 × 2 × 2 mm) were obtained from extracted primary teeth, which were randomly divided into the following groups based on the pretreatments (n = 12): DW (deionized water), NaF (2 % sodium fluoride), 2BAG (2 % BAG), 4BAG (4 % BAG), 6BAG (6 % BAG), and 8BAG (8 % BAG). The specimens were immersed in the respective solutions for 2 min and subjected to in vitro erosive challenges (4 × 5 min/d) for 5 d. The erosive enamel loss (EEL), erosive dentin loss (EDL), and the thickness of the demineralized organic matrix (DOM) were measured using a contact profilometer. The surface microhardness (SMH) was measured, and the percentage of SMH loss (%SMHL) was calculated. The surface morphology and mineral composition were evaluated by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), respectively. RESULTS After the erosive challenges, the EEL, EDL, and%SMHL of the 2BAG, 4BAG, 6BAG, and 8BAG groups significantly reduced, with the greatest reduction was observed in the 6BAG (EEL: 6.5 ± 0.2 μm;%SMHL in enamel: 12.8 ± 2.6; EDL: 7.9 ± 0.3 μm; %SMHL in dentin: 22.1 ± 2.7) and 8BAG groups (EEL: 6.4 ± 0.4 μm;%SMHL in enamel: 11.0 ± 1.9; EDL: 7.8 ± 0.5 μm; %SMHL in dentin: 22.0 ± 2.5) (P < 0.05). With increasing BAG concentrations, the number of surface deposits containing Ca, P, and Si increased. CONCLUSIONS 6BAG was the most effective for preventing dental erosion in primary teeth and showed a particularly strong potential for dentin erosion prevention. CLINICAL SIGNIFICANCE Bioactive glass, especially at a 6 % concentration, has proven effective in reducing erosive tooth wear and surface microhardness loss while also protecting demineralized organic matrix in primary dentin.

Abstract
OBJECTIVES Previous studies on short- and long-term pellicles showed that the enamel pellicle provides partial protection against erosion. The aim of the present study was to investigate the protective properties of clinically relevant pellicles formed within 2 to 24 h. The hypothesis was that factors such as pellicle formation time, intraoral location, and acidic challenge severity would not influence the erosion-protective properties of the pellicle. METHODS Six subjects participated in the study. Bovine enamel specimens were prepared and intraorally exposed at buccal or palatal sites for 2, 6, 12, and 24 h to allow pellicle formation, followed by erosion using 0.1 % or 1 % citric acid. Calcium release and surface microhardness were measured, and specimens were analysed using scanning and transmission electron microscopy. Quantitative data were statistically analysed with three-way ANOVA and Tuckey's multiple comparison test (p = 0.05). RESULTS Pellicle formation time and intraoral location did not significantly influence the erosion-protective properties of the pellicle, while citric acid concentration significantly affected enamel erosion. The pellicle thickness increased with longer formation times and on buccal sites, but decreased or was entirely removed following treatment with 0.1 % or 1 % citric acid, respectively. The enamel surface exhibited a characteristic erosion pattern. CONCLUSIONS This study underscores the importance of investigating pellicle properties within the critical 2- to 24-h timeframe and highlights the significance of pellicle thickness in acid resistance. CLINICAL SIGNIFICANCE These findings provide valuable insights into the factors influencing the protective properties of enamel pellicles and could guide preventive measures in dental practice.

Abstract
PURPOSE To evaluate deep learning-based segmentation models for oropharyngeal squamous cell carcinoma (OPSCC) using CT and MRI with nnU-Net. METHODS This single-center retrospective study included 91 patients with OPSCC. The patients were grouped into the development (n = 56), test 1 (n = 13), and test 2 (n = 22) cohorts. In the development cohort, OPSCC was manually segmented on CT, MR, and co-registered CT-MR images, which served as the ground truth. The multimodal and multichannel input images were then trained using a self-configuring nnU-Net. For evaluation metrics, dice similarity coefficient (DSC) and mean Hausdorff distance (HD) were calculated for test cohorts. Pearson's correlation and Bland-Altman analyses were performed between ground truth and prediction volumes. Intraclass correlation coefficients (ICCs) of radiomic features were calculated for reproducibility assessment. RESULTS All models achieved robust segmentation performances with DSC of 0.64 ± 0.33 (CT), 0.67 ± 0.27 (MR), and 0.65 ± 0.29 (CT-MR) in test cohort 1 and 0.57 ± 0.31 (CT), 0.77 ± 0.08 (MR), and 0.73 ± 0.18 (CT-MR) in test cohort 2. No significant differences were found in DSC among the models. HD of CT-MR (1.57 ± 1.06 mm) and MR models (1.36 ± 0.61 mm) were significantly lower than that of the CT model (3.48 ± 5.0 mm) (p = 0.037 and p = 0.014, respectively). The correlation coefficients between the ground truth and prediction volumes for CT, MR, and CT-MR models were 0.88, 0.93, and 0.9, respectively. MR models demonstrated excellent mean ICCs of radiomic features (0.91-0.93). CONCLUSION The self-configuring nnU-Net demonstrated reliable and accurate segmentation of OPSCC on CT and MRI. The multimodal CT-MR model showed promising results for the simultaneous segmentation on CT and MRI. CLINICAL RELEVANCE STATEMENT Deep learning-based automatic detection and segmentation of oropharyngeal squamous cell carcinoma on pre-treatment CT and MRI would facilitate radiologic response assessment and radiotherapy planning. KEY POINTS • The nnU-Net framework produced a reliable and accurate segmentation of OPSCC on CT and MRI. • MR and CT-MR models showed higher DSC and lower Hausdorff distance than the CT model. • Correlation coefficients between the ground truth and predicted segmentation volumes were high in all the three models.

[PMID: 39045263 PMCID: PMC11263942 DOI: 10.1016/j.gore.2024.101445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 06/12/2024] [Accepted: 06/26/2024] [Indexed: 07/25/2024] Open
Abstract
The WHO's initiative to eliminate cervical cancer by 2030 does not address the increasing incidence of vulvar, anal, and oropharyngeal cancers linked to high-risk HPV. Currently, the prevention of these three cancers faces various obstacles, such as a lack of specialized screening programs, well-defined management guidelines, and widespread public awareness. Without any interventions, the incidence of these three cancers will likely rise in the upcoming years, increasingly affecting younger individuals. We recommend expanding the WHO's initiative to include vulvar, anal, and oropharyngeal cancers. This involves developing screening and management protocols similar to those for cervical cancer, implementing gender-neutral HPV vaccination programs, establishing clear referral pathways to specialized centers, promoting public awareness, and providing education to healthcare providers and high-risk individuals.

Abstract
INTRODUCTION Head and neck squamous cell carcinomas (HNSCCs) have an increasing incidence, high recurrence, and an overall unfavorable prognosis despite numerous treatment options. The distinct immune landscape of HNSCC suggests a potential for immune-related biomarkers to aid classification and treatment planning. AREAS COVERED Immunoscore, a multiplex measure of tumor-infiltrating immune cells, is currently approved in colorectal carcinoma and is under investigation in various other cancer types. Recent studies have tried to implement the immunoscore and other novel immune cell-based scoring systems in HNSCC as predictors of survival. This study provides an overview of tumor-infiltrating immune cells and their prognostic significance, as well as a comparative summary of studies introducing an immunoscore in HNSCC. EXPERT OPINION With sufficient insight of the current literature, future studies could lead to the definition and validation of a new immune-based classification system for HNSCC. Such a classification strategy could be the basis for patient selection and, thus, optimize treatment outcomes and reduce unwanted complications. The heterogeneity of HNSCC subtypes, as well as the intratumoral variability of immune infiltrates, should be accounted for in the immunoscore.

Abstract
PURPOSE OF REVIEW Tessier number 3 and 4 clefts result from failed fusion of facial processes during embryogenesis, and cause functional, psychosocial, and cosmetic morbidity. Given their rarity and heterogeneity, they present a unique challenge to the reconstructive surgeon, with limited literature for guidance. The purpose of this update is to summarize Tessier number 3 and 4 clefts with a focus on recent literature and expert opinion. RECENT FINDINGS The incidence of atypical facial clefts has been estimated between 1.4 and 4.9 per 100 000 live births. Several retrospective chart reviews have been published in recent years; however, the epidemiologic data remains limited. Surgical management must be individualized and guided by classic reconstructive principles. The goal of surgery is to return the three soft tissue components (lip, nasomalar, and eyelid) to their proper anatomical location. SUMMARY Tessier number 3 and 4 clefts are rare, demonstrate a wide spectrum of clinical presentation, and remain challenging to gain a breadth of experience for any single surgeon. They are classified based on their location along well defined anatomical axes. Component repair is performed with attention to the lip, nasomalar, and eyelid regions to restore facial symmetry and function.

Abstract
OBJECTIVE This article aims to assess the reproducibility of Manufacturer and User Facility Device Experience (MAUDE) data-driven studies by analyzing the data queries used in their research processes. METHODS Studies using MAUDE data were sourced from PubMed by searching for "MAUDE" or "Manufacturer and User Facility Device Experience" in titles or abstracts. We manually chose articles with executable queries. The reproducibility of each query was assessed by replicating it in the MAUDE Application Programming Interface. The reproducibility of a query is determined by a reproducibility coefficient that ranges from 0.95 to 1.05. This coefficient is calculated by comparing the number of medical device reports (MDRs) returned by the reproduced queries to the number of reported MDRs in the original studies. We also computed the reproducibility ratio, which is the fraction of reproducible queries in subgroups divided by the query complexity, the device category, and the presence of a data processing flow. RESULTS As of August 8, 2022, we identified 523 articles from which 336 contained queries, and 60 of these were executable. Among these, 14 queries were reproducible. Queries using a single field like product code, product class, or brand name showed higher reproducibility (50%, 33.3%, 31.3%) compared with other fields (8.3%, P = 0.037). Single-category device queries exhibited a higher reproducibility ratio than multicategory ones, but without statistical significance (27.1% versus 8.3%, P = 0.321). Studies including a data processing flow had a higher reproducibility ratio than those without, although this difference was not statistically significant (42.9% versus 17.4%, P = 0.107). CONCLUSIONS Our findings indicate that the reproducibility of queries in MAUDE data-driven studies is limited. Enhancing this requires the development of more effective MAUDE data query strategies and improved application programming interfaces.

Abstract
OBJECTIVES This study aimed to evaluate the effect of virtual reality distraction (VRD) on dental anxiety during scaling and root planing (SRP) in periodontitis patients. MATERIALS AND METHODS This randomized controlled split-mouth study included 60 patients who scored 9 or above on the dental anxiety scale (DAS) and required SRP in at least two quadrants with at least five teeth and two sites with a probing depth of ≥4 mm. Randomly chosen quadrants were treated using virtual reality glasses, and other quadrants were treated without glasses at the same visit. During VRD, a video of nature scenes was projected onto the screen in front of the patient's eyes. DAS and a visual analogue scale about patient feelings were applied at the end of the procedure. RESULTS With VRD, the scale value of pain and discomfort level (VASP) was significantly reduced (p = 0.01, d = 0.57). Starting treatment without glasses significantly decreased VASP in both control and test sides (p = 0.00, d = 0.85; p = 0.00, d = 0.80, respectively) and increased the sensation of immersion and realism (p = 0.03, d = 0.45; p = 0.02, d = 0.46, respectively). Intraoperative and postoperative DAS values were significantly lower in patients who started treatment without VRD (p = 0.04, d = 0.34; p = 0.02, d = 0.44, respectively). Of the patients, 63.3% preferred VRD in the subsequent treatment. While patient preference did not correlate with sex, it correlated with age (r = -0.48, p = 0.01). CONCLUSIONS The VRD and initiating SRP procedure with VRD affected the pain and discomfort level in anxious periodontitis patients. In addition, the anxiety level was also affected by starting the procedure with glasses.

Abstract
INTRODUCTION During dental treatment procedures ultrasonic scalers generate droplets containing microorganisms such as bacteria and viruses. Hence, it is necessary to study the dynamic properties of generated droplets in order to investigate the risks associated with the spread of infection. The aim of this study was to visualise the flow state of droplets and to evaluate the impact of droplets generated during the use of an ultrasonic scaler during an oral surgical procedure. METHODS We studied the spatial flow of liquid droplets through a combination of imaging and numeric simulation of a simulated dental treatment processes. First, we photographed the real time images of the ultrasonic scaler and evaluated the images using image-processing software Image J to visualise the flow of liquid droplets. Finally we simulated the flow process of liquid droplets by using the initial velocity of droplet splashing and the angle of the obtained information using computerised fluid dynamics technology. RESULTS Under different working conditions, the droplet particle splashing velocity, maximum height, and spray angle varied, but the particle trajectory was generally parabolic. The maximum droplet velocity varied between 3.56 and 8.56 m/s, and the splashing height was between 40 and 110 mm. CONCLUSIONS During risk assessment of an ultrasonic scaler usage, difficulties arise due to the insufficient research on droplet velocity and distribution. This study aims to address this gap by visualising the flow trajectories of droplets generated by ultrasonic scalers. The obtained data will assist in developing more effective interventions based on spatial and temporal distribution of droplets. This provides a new approach for droplet particle research and offers new strategies for public health prevention and control.

The oral organ: A new vision of the mouth as a whole for a gerophysiological approach to healthy aging. Ageing Res Rev 2024; 99:102360.

Abstract
This article brings a new perspective on oral physiology by presenting the oral organ as an integrated entity within the entire organism and its surrounding environment. Rather than considering the mouth solely as a collection of discrete functions, this novel approach emphasizes its role as a dynamic interphase, supporting interactions between the body and external factors. As a resilient ecosystem, the equilibrium of mouth ecological niches is the result of a large number of interconnected factors including the heterogeneity of different oral structures, diversity of resources, external and internal pressures and biological actors. The manuscript seeks to deepen the understanding of age-related changes within the oral cavity and throughout the organism, aligning with the evolving field of gerophysiology. The strategic position and fundamental function of the mouth make it an invaluable target for early prevention, diagnosis, treatment, and even reversal of aging effects throughout the entire organism. Recognizing the oral cavity capacity for sensory perception, element capture and information processing underscores its vital role in continuous health monitoring. Overall, this integrated understanding of the oral physiology aims at advancing comprehensive approaches to the oral healthcare and promoting broader awareness of its implications on the overall well-being.

Abstract
OBJECTIVES To evaluate the longevity of cantilevered zirconia-based resin-bonded fixed partial dentures (RBFPDs) in replacing missing posterior teeth, as well as the quality of life and patient satisfaction experienced by those receiving zirconia RBFPDs. METHODS A prospective single-arm uncontrolled clinical trial was conducted to replace one or more missing premolars or molars with a span of 5 to 8 mm using cantilevered zirconia RBFPDs. Thirty-six participants with 40 prostheses were recruited and underwent a 3-year clinical evaluation. The retainer designs included a minimum thickness of 0.8 mm, a minimum of 200° circumferential wraparound with an occlusal bar, and a connector dimension of 3 × 3 mm. Patient-reported outcomes, including patient satisfaction and Oral Health Impact Profile (OHIP), were assessed. RESULTS The average age of participants was 45.8 years, and 72.5 % were women. The success rate of the posterior zirconia RBFPDs was 76.2 %, with an estimated mean success duration of 46.1 months. The survival rate was 88.1 %, with an estimated mean survival duration of 49.4 months. Participants were highly satisfied with the treatment, achieving an average satisfaction score of 80.8 ± 11.9. Participants' total OHIP scores decreased from 52.3 to 39.6 after 3 years, indicating a significant improvement in oral health-related quality of life (P = 0.009). CONCLUSIONS After 3 years, a moderately high survival rate and favourable patient-reported outcomes of posterior cantilevered zirconia RBFPDs were achieved. Therefore, it can be recommended as a conservative treatment option to replace missing posterior teeth, provided that retainer design considerations are taken into account. CLINICAL SIGNIFICANCE Cantilevered zirconia RBFPDs for posterior teeth can serve as a conservative treatment option that is both aesthetically pleasing and biocompatible. It offers a more cost-effective alternative compared to dental implants, which are often prohibitively expensive for the majority of patients. This approach has the potential to greatly improve patient-reported outcomes.

Abstract
OBJECTIVE The aim of this study was to evaluate the use and reintervention rate of fillings compared to preformed metal crowns in the everyday clinical practice of German dentists. METHODS In this retrospective, longitudinal analysis, fee codes from the Kassenzahnärztliche Vereinigung Westfalen-Lippe for restorations placed in primary molars between 2012 and 2015 in children until 7 years of age followed for a 7-year period (latest until December 2022) were filtered and analyzed with the Fine and Gray competing risk regression and Cox proportional hazards regression to calculate the risk of reintervention divided into the main outcomes "Successful", "Minor Failure/Repair" and "Major Failure/Endodontic Treatment/Extraction". 367,139 primary molars (one-surface fillings: n = 117,721; two-surface fillings n = 198,815; three-surface fillings n = 36,695; more than three-surface fillings n = 8,267 and preformed metal crowns n = 5,641 were included in this study. RESULTS Teeth treated with preformed crowns needed significantly less re-interventions. Subdistribution hazard ratio for minor events was 0.117 (95 %-CI: 0.097 to 0.141) and hazard ratio of major events (HR=0.786; 95 %-CI: 0.695 to 0.890) when compared to one-surface fillings in multivariable adjusted analysis. Within 7-year follow-up preformed crowns required less repairs (80.6 % success rate, minor failure 4.4 %, major failure 16.3 %) than the teeth treated with composite fillings (46.2 %-52.6 % success rate, minor failure 27.0 %-39.5 %, major failure 15.5 %-28.4 %, p < 0.001). CONCLUSION Within the German healthcare system fillings are the first choice for treating primary molars despite considerably higher reintervention rates. This encourages a discussion on the indication of fillings and the more durable preformed metal crowns to reduce unnecessary reintervention in young children. CLINICAL SIGNIFICANCE This study gives an unprecedented insight into the German healthcare system regarding the reintervention rates of the most relevant treatment techniques for caries in primary molars.

Abstract
INTRODUCTION The recent pandemic has highlighted the importance of addressing well-being in the overall health of students. There is a need for support systems within dental schools to help students demonstrate resilience, adapt to learning environments and thrive in their professional careers. OBJECTIVES The main aim of the study was to evaluate Bachelor of Dental Surgery (BDS) students' understanding and experience of well-being. The objectives were to create a suitable survey to assess students' well-being, investigate the factors affecting dental students' well-being and develop a student well-being action plan based on the analysis of the survey. METHODS A literature review was conducted to identify and critically assess existing measures of well-being in dental students. Four domains of well-being (emotional, physical, social, intellectual) relevant to dental students were identified. Through a comprehensive iterative process, a two-part survey was developed and tested, which measured individual experiences of well-being across the four domains and collected feedback on proposed initiatives to support student well-being. The survey was disseminated to all 452 dental students from Years 1 through 6, of which 71% (321) responded. RESULTS The survey revealed low levels of overall well-being among the dental student population, which worsened with increasing years of clinical study. Fear of failing exams presented the biggest challenge with regard to emotional well-being, while sleep deprivation and occupational health hazards most affected the physical well-being domain. Intellectual well-being was compromised by insufficient free time to pursue extracurricular interests and concerns about achieving the required skills. Despite a majority experiencing positive relationships with their peers and tutors, less than a fifth agreed that the Faculty of Dentistry 'supported my well-being as a dental student'. CONCLUSION As the first investigation of the well-being of dental students in Hong Kong, the key stressors identified were examinations, long schedules and the physical burden of dental work, which are consistent with international literature. The findings reveal students' needs and preferences for well-being initiatives which will be optimized in the implementation of student-centred curricular activities.

[PMID: 38291733 DOI: 10.1111/jerd.13201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 01/18/2024] [Accepted: 01/18/2024] [Indexed: 02/01/2024]
Abstract
OBJECTIVE Agenesis of the maxillary permanent lateral incisors is a condition that requires treatment aimed at improving the esthetics, even at an early age. However, traditional therapeutic protocols are long, invasive and have limitations and contraindications imposed by the age of the patient. CLINICAL CONSIDERATIONS Recent developments in restorative dentistry have provided a new approach to this clinical situation, in particular when the deciduous laterals are retained. We report two cases regarding the management of missing lateral incisors using Biologically Active Intrasulcular Restoration (BAIR) technique. The BAIR technique allows us to transform the shape of the deciduous lateral incisor into the permanent, acting both on the dental morphology and proportions, and on the appearance of the soft tissues and the gingival parables. CONCLUSIONS The BAIR technique is a valid approach to cases of agenesis of the maxillary permanent lateral incisors, when the deciduous are retained. It does not require any preparation of the dental tissues, is reversible and minimally invasive. It is applicable to patients of all ages, and results are obtained in a single appointment. CLINICAL SIGNIFICANCE The BAIR technique allows a biomimetic conservative approach for the rehabilitation of congenitally missing permanent lateral incisors, when the deciduous are retained. It is a non-invasive protocol and effective in successfully restoring esthetics.

Abstract
BACKGROUND The workplace is an ideal-and priority-setting for health promotion activities. Developing and implementing workplace health promotion interventions, including oral health promotion activities, can help create health-supporting workplace environments. OBJECTIVE To pilot workplace oral health promotion activities among staff working in the aged care sector, report their impact and explore participants' views on the factors that contribute to participation and effectiveness. METHODS This study comprised three phases: (i) the development and face validation of the resources, (ii) a 3-h educational session and (iii) five interview sessions with participants 4-6 weeks following the education session. The recorded interviews were transcribed verbatim and analysed thematically. RESULTS Eleven community-aged care workforce were invited to five feedback sessions. Ten participants were female and ranged in age from 18 to 64. All participants gave favourable comments about the content and delivery of the training session and accompanying resources. The participants felt that the benefits of WOHP include improved staff knowledge, awareness and oral care routine, the ability to share (and put into practice) the gained knowledge and information with their dependants, a lower risk of having poor oral health that adversely affects their well-being and work tasks, and potentially beneficial impacts on the organization's staff roster. Their attendance in the WOHP was facilitated by being paid to attend and scheduling the sessions during work time. Future WOHP suggestions include the possibility of a one-stop dental check-up at the workplace or staff dental care discounts from local dental practitioners and combining oral health with other health promotion activities. CONCLUSIONS Planning and implementing WOHP was deemed acceptable and feasible in this study context and successfully achieved short-term impacts among community-aged care workers. Appropriate times and locations, organizational arrangements and a variety of delivery options contributed to successful programme planning and implementation.

Dent Mater 2024; 40:1138-1163. [PMID: 38825554 DOI: 10.1016/j.dental.2024.05.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 04/17/2024] [Accepted: 05/13/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND Root canal irrigation endodontic solutions have effects on the chemistry of dentin. Infrared spectroscopy is a non-destructive chemical characterization method where the strength of absorption often correlates with mineral or organic composition. OBJECTIVES To survey effects of commonly used irrigation solutions on the composition of root dentin as detected by widely-available Fourier transform infrared spectroscopy (FTIR) methods. METHODS Electronic databases were searched for articles published between 1983 to 2023. After risk of bias assessments (OHAT), studies were grouped according to effects per irrigation solution. Inclusion criteria comprised in vitro studies that used extracted human or bovine teeth, treated by irrigation solutions characterized using FTIR spectroscopy and presenting spectral data. Publications that did not present spectra were excluded. RESULTS A wide range of concentrations, durations, and treatment protocols have been tested but only 30 out of 3452 studies met our inclusion criteria. Different FTIR methods were used with Attenuated Total Reflection (ATR) variant being the most common (21 studies). Investigated solutions included sodium hypochlorite (NaOCl), ethylenediaminetetraacetic-acid (EDTA), 1-hydroxyethylidene-1-1-diphosphonic-acid (HEDP), peracetic-acid (PAA), glycolic-acid (GA), and citric-acid (CA) though most focused on NaOCl and EDTA. All solutions had detectable effects in the FTIR signature of dentin. NaOCl mainly affects the organics, revealing reduced amide/phosphate ratios with increasing concentrations. EDTA mainly effects the inorganic component, with the effects increasing with time and concentration, yet glycolic acid has stronger effects than EDTA on dentin. Beyond the type of irrigant and dentin exposure durations, concentration and protocol of application had strong effects. There is a lack of studies comparing similar irrigants under conditions that mimic clinical scenarios analyzing bulk sample because FTIR of powder dentin differs from FTIR of bulk dentin. SIGNIFICANCE The ideal root-canal irrigant should combine local disinfection properties with minimal compositional effects on healthy dentin. FTIR methods appear reliable to identify important changes in root dentin chemical composition. Such information can help understand when endodontic irrigation might lead to root degradation or possibly contribute to long term failures such as vertical fractures. Awareness of chemical damage from irrigation procedures may help clinicians select procedures that reduce deleterious effects on the root canal structures.

Abstract
BACKGROUND AND OBJECTIVES This study explores the narrated experiences of individuals with advanced stages of late-onset dementia, focusing on their diagnosis awareness. Such framing is motivated by 2 reasons. Firstly, there is a lack of consensus regarding the prevalence of anosognosia among people with dementia. Secondly, research on anosognosia often neglects to address the important issues of shame and stigma associated with receiving a dementia diagnosis. RESEARCH DESIGN AND METHODS For this qualitative study, a total of 27 participants ranging in age from 66 to 94 were involved. The data collected were analyzed using textual-oriented discourse analysis. RESULTS Our findings indicated that individuals with dementia struggled to comprehend the medical terminology used to describe their experiences within biomedical standards. The interviewees utilized 5 negative discourses on dementia, which shaped their attitudes toward the condition and people diagnosed with it. These discourses depicted dementia as an illness, negative aging, a devaluation, a burden, and a life tragedy. Moreover, study participants did not outright reject the diagnosis but rather negotiated its acceptance within the context of shame associated with dementia. DISCUSSION AND IMPLICATIONS The concept of anosognosia can serve as a mechanism of social control and stigmatization of people with dementia within the dominant biomedical discourse.

Abstract
OBJECTIVES This study evaluated the clinical performance of bulk-fill resin composite systems with different viscosities in class II cavities. MATERIALS AND METHODS A total of 80 class II restorations were performed with a single operator in 50 patients using four different bulk-fill resin composite materials: Filtek™ Bulk Fill, Heated Filtek™ Bulk Fill, G-ænial™ BULK Injectable, and SonicFill3. A double-blinded randomized clinical trial was designed to evaluate the two-year clinical performance of the four bulk-fill composite resins using modified FDI criteria. Data were analyzed descriptively. Level of significance was set at 0.05. Differences between groups were tested using Wilcoxon-signed-rank and Mann-Whitney-U test as nonparametric tests. RESULTS Data were analyzed using Kruskal-Wallis, Mann-Whitney U, and Wilcoxon signed rank tests (p < 0.05). Eighty restorations were available for evaluation, with a survival function of 100%. No statistically significant differences were observed between the four groups regarding assessing esthetic, functional, and biological properties during different follow-up periods. CONCLUSIONS After 2 years of clinical follow-up, the bulk-fill composite systems with different viscosities seem to be esthetically, functionally, and biologically acceptable, with a promising clinical performance in class II cavities.

Abstract
OBJECTIVES This study aims to update the relevant epidemiological information of untreated caries in permanent teeth. METHODS Data were derived from the Global Burden of Disease (GBD) study 2019. We described temporal trends in age-standardized prevalence rate (ASPR) of untreated caries in permanent teeth by gender and region from 1990 to 2019. Age-period-cohort (APC) model was utilized to analyze age, period and cohort effects on prevalence, and we used the Bayesian age-period-cohort (BAPC) model to make projections of prevalence between 2020 and 2049. RESULTS The global ASPR of untreated caries in permanent teeth presented a decreasing trend from 1990 to 2019 (26593.58/105 vs. 25625.53/105), with females exceeding males annually. Negative correlation was observed between ASPR and Socio-demographic Index (SDI) levels. APC analyses showed that net drift was -0.16 % globally and generally below 0 across all SDI regions. The overall global peak in prevalence occurred in the 20-24 years group (36319.99/105), and there was a decrease trend in the overall global period rate ratio (RR). Compared to younger birth cohorts, prior birth cohorts had higher prevalence risks globally and across all SDI regions. Significant upward trends was predicted in the global ASPR of untreated caries in permanent teeth for both genders from 2020 to 2049. CONCLUSIONS Age-period-cohort effects exerted a significant impact on the prevalence of untreated caries in permanent teeth during the study period. CLINICAL SIGNIFICANCE The ASPR of untreated caries in permanent teeth may increase in the next 30 years by projections. And the disease burden of untreated caries in permanent teeth may be affected by population ageing. It is essential to implement targeted prevention and control policies to disadvantaged groups and attempt to reduce caries inequalities.

Abstract
OBJECTIVE The study aimed to compare self-perceived oral health and orofacial appearance in three different cohorts of 60-year-old individuals. METHOD A cross-sectional design, based on data obtained from a questionnaire used in the Swedish National Study of Aging and Care. The sample comprised 478 individuals, from baseline, 2001-2003 (n = 191), 2007-2009 (n = 218) and 2014-2015 (n = 69). Comparisons were made within and between the cohorts, with bivariate analysis and Fisher's exact test. Statistical significance was considered at p < 0.05. RESULTS The result showed that a low number of the participants reported self-perceived problems with oral health. Of the problems reported, a higher proportion in cohort 2014-2015 (39.3%) experienced problems with bleeding gums. The experience of bleeding gums increased between the cohorts 2001-2003 and 2014-2015 (p = 0.040) and between 2007-2009 and 2014-2015 (p = 0.017). The prevalence of discomfort with sensitive teeth was experienced in 7%-32%. Twice as many women compared to men experienced discomfort in all cohorts (no significant differences between the cohorts). Satisfaction with dental appearance was experienced in 75%-84%. Twice as many women compared to men were dissatisfied with their dental appearance in 2001-2003 (p = 0.011) and with discoloured teeth (p = 0.020). No significant differences could be seen between the cohorts regarding discomfort with dental appearance or discoloured teeth. CONCLUSION The 60-year-olds irrespective of birth cohort, perceived their oral health and orofacial appearance as satisfactory.

Abstract
OBJECTIVE The aim of this study was to assess the response of dental health care workers in Indonesia to the COVID-19 pandemic through (1) a countrywide web-based, questionnaire survey of their knowledge, attitude, and infection control (IC) practices during the pandemic and (2) a focus group discussion (FGD) on the latter aspects with infected personnel, as well as (3) archival data collection on the epidemiology of COVID-19 amongst dentists in Indonesia. METHODS A questionnaire survey using a web platform was conducted in May 2020 using a simple random sample of 3586 dentists working in different regions of Indonesia. The questionnaire attempted to elicit their knowledge and attitudes towards COVID-19, implementing IC measures, and providing dental care during the outbreak. The questionnaire comprised sections assessing participants' knowledge, awareness, and IC practice. In this study, the data were subjected to analysis through descriptive statistics and one-way analysis of variance (ANOVA) with a predetermined significance level of <.05. The study's second phase involved an FGD with dentists who had contracted the disease to discuss the impediments they faced during dental practice. We collected data on the number of dentists with COVID-19 from May 2020 to March 2022. RESULTS The questionnaire survey revealed that the dentists had a satisfactory understanding of COVID-19 spread and the IC measures required to curb disease spread in the dental clinic. Of note, some dentists lacked knowledge of the incubation period of 5 days (21.19%). The vast majority of the respondents (>80%) were aware of the nature of the SARS-CoV-2 virus. Community health centres and the personnel who served there were the most exposed health care providers. CONCLUSIONS Results suggest that the vast majority of the dental care professionals in Indonesia had adequate knowledge and awareness of COVID-19. However, some aspects of practice need to be improved in IC and related aspects.

Abstract
OBJECTIVES This study aims to evaluate antibacterial effects of silver diamine fluoride (SDF), SDF/potassium iodide (KI), and nanosilver fluoride (NSF). METHODS Antimicrobial activity of sterile saline, 5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), SDF, SDF/KI, NSF, and KI solutions against Streptococcus mutans and Lactobacillus casei was assessed through disc diffusion tests. A dual-species biofilm of S. mutans-L. casei was formed on 48 enamel samples, divided into six groups (n = 8). Group 1 was treated with sterile saline, Group 2 with 5% NaOCl, Group 3 with 2% CHX, Group 4 with SDF, Group 5 with SDF/KI, and Group 6 with NSF. The samples were analysed using confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM). Statistical analysis utilized Shapiro-Wilk and Kruskal-Wallis tests and multiple comparisons were conducted using Dunn test. RESULTS SDF, SDF/KI, and NaOCl displayed significantly higher antibacterial activity against dual-species biofilm compared to NSF and CHX (p < 0.050). CONCLUSIONS In conclusion, SDF and SDF/KI demonstrated greater antibacterial activity than NSF. SDF's antibacterial activity was unaffected by KI. Further research is needed to determine the appropriate content and concentration for achieving effective antibacterial activity with NSF. CLINICAL SIGNIFICANCE The use of silver-containing materials is increasing in popularity within pediatric dentistry. In this study, an endeavor has been made to assist pediatric dentists in determining which solution might be more advantageous for preventing caries.

Abstract
OBJECTIVE To summarize studies published between 2017 and 2023 examining the clinical diagnosis and restorative management of amelogenesis imperfecta (AI) in children and adolescents. DATA The review incorporated publications on clinical diagnosis, patient-reported outcomes, clinical trials, cohort studies, and case reports that included individuals below 19 years of age with non-syndromic AI. SOURCES A literature search was conducted across electronic databases, PubMed, Web of Science, and CINAHL, including papers published between 2017 and 2023. The search yielded 335 unique results, of which 38 were eligible for inclusion. RESULTS New evidence on the genetic background of AI makes it now advisable to recommend genetic testing to supplement a clinical AI diagnosis. The discussions of the dental profession and the public on social media do not always incorporate recent scientific evidence. Interview studies are finding that the impact of AI on quality of life is more severe than previously appreciated. New evidence suggests that single-tooth ceramic crowns should be the first choice of treatment. Due to incomplete reporting, case reports have been of limited value. CONCLUSION In young patients with AI symptoms of pain and hypersensitivity decreased, and aesthetics were improved following all types of restorative therapy. Resin composite restorations were mainly performed in cases with hypoplastic AI and mild symptoms. Single tooth ceramic crown restorations have a high success rate in all types of AI and can be used in young individuals with AI. CLINICAL SIGNIFICANCE Prosthetic rehabilitation in adolescents with severe AI is cost effective, improves esthetics, reduces tooth sensitivity, and improves oral health-related quality of life.

Albashaireh ZSM, Sbeih YK. The effect of ferrule and core material on fracture resistance of endodontically treated anterior teeth restored with ceramic crowns after artificial aging. J Dent 2024; 147:105106. [PMID: 38830530 DOI: 10.1016/j.jdent.2024.105106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 05/28/2024] [Accepted: 05/31/2024] [Indexed: 06/05/2024] Open
Abstract
OBJECTIVES To assess the influence of ferrule and core type on the fracture strength of endodontically treated anterior teeth (ETAT) and identify the failure mode type and distribution across different core types and ferrule conditions. METHODS Sixty extracted human central incisors were endodontically treated, decoronated and divided into two main groups (F=with ferrule, NF=no ferrule). Each main group was further subdivided into three subgroups according to the core material used: direct composite cores (DC), Ribbond fibre-reinforced composite cores (RIB-DC), and glass fibre post (GFP) with direct composite cores (GFP-DC). All specimens received E.max crowns and underwent thermal cycling and cyclic loading. Subsequently, the fracture resistance was tested with static loads applied to the crown restoration. Two-Way ANOVA and Chi square tests identified significant differences among the groups (p < 0.05). RESULTS The means and standard deviations (SD) of fracture loads in Newtons (N) for specimens in the F subgroups were RIB-DC: 465.0 (104.20), GFP-DC: 367.6 (79.59), DC: 275.8 (68.48), and in NF subgroups were RIB-DC: 110.8 (24.33), GFP-DC: 95.6 (25.47), DC: 67.4 (7.46). Specimens with ferrule yielded significantly higher fracture loads than those without ferrule (p = 0.0054). In the F groups, fracture loads of specimens with RIB-DC cores were significantly higher than those with GFP-DC (p = 0.0019) and those with DC (p = 0.0001). Moreover, fracture loads for the GFP-DC were significantly higher than those for the DC (p = 0.0026). The GFP-DC specimens showed the highest incidence of catastrophic failures (p = 0.0420). CONCLUSIONS Using fibre-reinforced composite (FRC) cores significantly increased fracture resistance in ETAT with ferrule. The failure modes repairable and possibly repairable were dominant in most specimens. CLINICAL SIGNIFICANCE When restoring ETAT with insufficient coronal tooth structure, preserving 2 mm of tooth structure ferrule and preparing cores with FRC can increase fracture resistance and reduce the incidence of non-repairable catastrophic fractures of teeth.

Characterization and quantification of in-vitro equine bone resorption in 3D using μCT and deep learning-aided feature segmentation. Bone 2024; 185:117131. [PMID: 38777311 DOI: 10.1016/j.bone.2024.117131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 05/18/2024] [Accepted: 05/19/2024] [Indexed: 05/25/2024]
Abstract
High cyclic strains induce formation of microcracks in bone, triggering targeted bone remodeling, which entails osteoclastic resorption. Racehorse bone is an ideal model for studying the effects of high-intensity loading, as it is subject to focal formation of microcracks and subsequent bone resorption. The volume of resorption in vitro is considered a direct indicator of osteoclast activity but indirect 2D measurements are used more often. Our objective was to develop an accurate, high-throughput method to quantify equine osteoclast resorption volume in μCT 3D images. Here, equine osteoclasts were cultured on equine bone slices and imaged with μCT pre- and postculture. Individual resorption events were then isolated and analyzed in 3D. Modal volume, maximum depth, and aspect ratio of resorption events were calculated. A convolutional neural network (CNN U-Net-like) was subsequently trained to identify resorption events on post-culture μCT images alone, without the need for pre-culture imaging, using archival bone slices with known resorption areas and paired CTX-I biomarker levels in culture media. 3D resorption volume measurements strongly correlated with both the CTX-I levels (p < 0.001) and area measurements (p < 0.001). Our 3D analysis shows that the shapes of resorption events form a continuous spectrum, rather than previously reported pit and trench categories. With more extensive resorption, shapes of increasing complexity appear, although simpler resorption cavity morphologies (small, rounded) remain most common, in acord with the left-hand limit paradigm. Finally, we show that 2D measurements of in vitro osteoclastic resorption are a robust and reliable proxy.

Abstract
PURPOSE Intraoral hair growth is a debilitating side effect of flap or graft-based oropharyngeal reconstruction. There is no standardized treatment, but groups have successfully eradicated unwanted hair growth with intraoral laser hair removal. This scoping review assesses the utility of laser therapy in managing this condition. METHODS This scoping review followed PRISMA-ScR guidelines. Ovid Medline, Embase (Ovid) and Scopus were queried using index terms and keywords. Resulting articles were reviewed for inclusion by two independent reviewers against inclusion criteria and relevant data were extracted. RESULTS The literature search yielded 297 articles, 22 of which met inclusion criteria. In total, 77 patients were treated: 38 patients with an Alexandrite laser, 19 with an Nd:YAG laser, 18 with a diode laser, and two with a CO2 laser. Complete response defined as 80% or more reduction in hair count was achieved in 70 patients (90%) and six patients (8%) achieved a partial response (10%-79% reduction in hair count). One patient (1%) with gray hair saw less than a 10% reduction in hair count. On average, 3.84 treatment sessions were needed, spaced 5.4 weeks apart. Treatments were well tolerated without major side effects. CONCLUSIONS This is the first scoping review assessing the utility of intraoral laser hair therapy and suggests it may be a safe and effective treatment. However, surgeons should advise preoperative hair removal when clinically feasible to mitigate this side effect as much as possible.

Clinical comparison of silver diamine fluoride (SDF) or silver-modified atraumatic restorative technique (SMART) on hypomineralised permanent molars with initial carious lesions: 3-year results of a prospective, randomised trial. J Dent 2024; 147:105098. [PMID: 38797490 DOI: 10.1016/j.jdent.2024.105098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 05/18/2024] [Accepted: 05/23/2024] [Indexed: 05/29/2024] Open
Abstract
OBJECTIVES This study aimed to assess the clinical outcomes of utilizing silver diamine fluoride + potassium iodide (SDF + KI) treatment and Silver-Modified Atraumatic Restorative Technique (SMART/SDF + KI + Glass Ionomer Cement) over a three-year period on hypomineralised permanent molars with initial carious lesions. METHODS 112 hypomineralised permanent molars with ICDAS 1 or 2 lesions were selected in 48 children. The teeth were randomized into SDF + KI and SMART (SDF + KI + GIC) groups (n = 56 teeth/group) in a split-mouth design. Hypersensitivity and caries development were evaluated in both groups. Schiff Cold Air Sensitivity Scale (SCASS) was used for evaluation of hypersensitivity, and the modified USPHS criteria were utilised for clinical assessments of SMART sealants at 1,6,12,18,24 and 36 months. Fisher's Exact test, Kaplan-Meier Survival Curves, Log-rank test, Mann Whitney U test, and Friedman test was performed for the statistical analysis. RESULTS The caries preventive effect was 100 %, 67.9 % and 65.4 % for SDF + KI-treated teeth; and 100 %, 97.6 % and 94.7 % for SMART(SDF + KI + GIC)-treated teeth at 12, 24 and 36 months, respectively. The mean survival probabilities for caries-preventive effect were significantly lower in SDF + KI-treated teeth (31.01 months) than SMART-treated teeth (35.61 months), (p < 0.001). Twenty-six molars with initial hypersensitivity due to hypomineralization demonstrated a significant reduction at all evaluation periods compared to baseline SCASS scores (p < 0.001). Additionally, there was no significant difference in hypersensitivity scores between the groups during the re-call periods, and none of the teeth exhibited hypersensitivity at the 18-month and beyond evaluations. CONCLUSIONS During the three-year assessment, both groups demonstrated effectiveness in reducing sensitivity in hypomineralised molars. However, SMART (SDF + KI + GIC) sealants offered better protection against tooth decay over time, despite experiencing gradual retention loss. CLINICAL SIGNIFICANCE Both SMART (SDF + KI + GIC) sealants and SDF + KI proved effective in alleviating hypersensitivity in hypomineralised molars for up to three years. SMART (SDF + KI + GIC) sealants showed greater caries-preventive effect compared to SDF + KI. However, continuous long-term monitoring is crucial due to the gradual decline in retention of SMART (SDF + KI + GIC) sealants. CLINICALTRIALS REGISTRATION NUMBER NCT03862014.

Abstract
OBJECTIVES The primary aim of the investigation was to survey clear aligner therapy (CAT) use among general dentists in Australia. A secondary aim was to evaluate the factors that influenced general dentists in Australia not to provide CAT. MATERIAL AND METHODS General dentists registered with the Australian Health Practitioner Regulation Agency were invited to participate in a structured cross-sectional electronic survey. The survey covered demographics, preferred CAT systems and practices, relevant treatment planning and retention protocols, patient-reported CAT issues, pertinent respondent opinions, and reasons for not providing CAT. Descriptive statistics were computed via GraphPad Prism v10 (GraphPad Software Inc., La Jolla, CA, USA). RESULTS Most of the 264 (n = 172; 65.2%) respondents indicated that they provided CAT. The majority (n = 82; 58.6%) reported that they treated between 1 and 20 patients with CAT annually. Invisalign was the most used system (n = 83; 61.2%), with 55 (41.7%), indicating that they used more than one system. Most (n = 124; 98.4%) were comfortable using CAT for mild crowding, whereas 73.4% (n = 94) were not comfortable in treating severe crowding with CAT. The median (IQR) number of patients per respondent treated with extraction of a permanent incisor or premolar was 0 (0). Issues regarding tooth positions were reportedly always or mostly in need of change in the initial treatment plan by 68.7%. Problems regarding patient compliance with CAT wear protocols (n = 67; 45.6%) and the predictability of treatment outcomes (n = 31; 21.1%) were the most identified themes of the free-text comments. Over 80% of those who did not provide CAT indicated that they preferred to refer to an orthodontist for management. CONCLUSION Almost two-thirds of the respondents provided CAT. Invisalign was the most used system. The majority use CAT combined with nonextraction treatment. Most of those who did not provide CAT preferred to refer to an orthodontist for patient management.

Abstract
PURPOSE OF REVIEW Acute facial pain presents a complex challenge in medical practice, requiring a comprehensive and interdisciplinary approach to its management. This narrative review explores the contemporary landscape of treating acute facial pain, delving into pharmacological, non-pharmacological, and advanced interventions. The significance of tailored treatment strategies, rooted in the diverse etiologies of facial pain, such as dental infections, trigeminal neuralgia, temporomandibular joint disorders, sinusitis, or neurological conditions like migraines or cluster headaches, is underscored. We particularly emphasize recent advances in treating trigeminal neuralgia, elucidating current treatment concepts in managing this particular acute facial pain. RECENT FINDINGS Recent research sheds light on various treatment modalities for acute facial pain. Pharmacotherapy ranges from traditional NSAIDs and analgesics to anticonvulsants and antidepressants. Non-pharmacological interventions, including physical therapy and psychological approaches, play pivotal roles. Advanced interventions, such as nerve blocks and surgical procedures, are considered in cases of treatment resistance. Moreover, we explore innovative technologies like neuromodulation techniques and personalized medicine, offering promising avenues for optimizing treatment outcomes in acute facial pain management. Modern management of acute facial pain requires a nuanced and patient-centric approach. Tailoring treatment strategies to the individual's underlying condition is paramount. While pharmacotherapy remains a cornerstone, the integration of non-pharmacological interventions is essential for comprehensive care. Advanced interventions should be reserved for cases where conservative measures prove inadequate. Furthermore, leveraging innovative technologies and personalized medicine holds promise for enhancing treatment efficacy. Ultimately, a holistic approach that considers the diverse needs of patients is crucial for effectively addressing acute facial pain.

Abstract
OBJECTIVES To analyze and define the concept of nurses' media competency. DESIGN Concept analysis. DATA SOURCES We conducted a literature search in PubMed, CINAHL, PsycInfo, and RISS International, as well as a hand-search, for relevant articles published between January 1990 and April 2023. A total of 57 articles related to nurses' media competency, published in English or Korean, were included in this study. REVIEW METHODS We used Walker and Avant's method of concept analysis to identify the defining attributes, antecedents, and consequences of the concept. RESULTS The seven defining attributes of nurses' media competency were networking with members of the media, selecting the appropriate media platform, considering that the target audience is the public, creating one's own media products, delivering intended messages through the media, monitoring and responding to the media, and maintaining professional dignity. Antecedents of the concept included cultivation of desirable nursing professionalism, critical evaluation of policies and issues, recognition of media influence, establishment of education and guidelines for media use, and having facilities and availability of technologies for media use. Consequences of the concept were improved influence of individual nurses, enhanced public awareness of the nursing profession, stronger networks and collaboration among professionals, and contributions to the promotion of public health. CONCLUSIONS This concept analysis presents a theoretical definition of nurses' media competency that can provide guidance on how to educate nurses to develop media competency and how to measure nurses' media competency.

Abstract
OBJECTIVES The Peruvian public health norm of primary healthcare (PHC) for growth and development medical check-ups (CRED, Spanish acronym) of children under 5 years of age was updated in 2017 with the inclusion of interdisciplinary prevention and control actions for oral diseases, such as dentist referral. The aim of this study was to explore the association between CRED and oral health services utilization (OHSU), throughout the heterogeneous Peruvian territory. METHODS A population-based cross sectional study was conducted using the 2021 Demographic and Family Health Survey of Peru and included data from 15 836 children aged 12-59 months. Poisson generalized linear models were used to evaluate the association between any CRED and OHSU, in the 6 months prior to the survey, including sociodemographic characteristics of the children and their mothers as confounding variables. A possible effect modification by natural region of residence (Metropolitan Lima/rest of the Coast/Highlands/Jungle) was evaluated. To examine the robustness of the regression model, a sensitivity analysis was performed using the cumulative number of CRED. RESULTS Children who had at least one CRED were almost twice as likely to report OHSU (aPR: 1.95; 95% CI: 1.73-2.21), which was greater in the regions of rest of the Coast (aPR: 2.56; 95% CI: 2.00-3.17) and Jungle (aPR: 2.03; 95% CI: 1.64-2.56). The sensitivity analysis showed consistent results for the association CRED-OHSU. Nevertheless, within the last 6 months, attendance at CRED and OHSU were only achieved by 43.7% and 13.7% of the children respectively. CONCLUSIONS Integrating oral health into Peruvian Child PHC seems to be a promising public health intervention to increase children's OHSU. For a greater scope, it is crucial to drive greater attendance at CRED and continuous monitoring and strengthening of CRED-based oral health promotion in all Peruvian natural regions with an equity-focused approach.

Abstract
OBJECTIVE The present study investigated bone remodelling in the upper and lower incisor regions depending on the inclination pattern during the alignment phase of orthodontic treatment (OT). MATERIALS AND METHODS This prospective clinical study included 71 patients undergoing OT without premolar extraction. Cone beam computed tomography scans were taken before and after the alignment phase and the changes in the inclination, alveolar bone height (ABH) and bone thickness (BT) at levels 2, 3, 4, 6, 8 and 9 mm starting from the cementoenamel junction (CEJ) were determined. RESULTS Teeth were divided into 'Retroinclination' (lingual crown inclination <0°), 'Proclination-low' (buccal crown inclination between 0° and 5°), or 'Proclination-high' (buccal crown inclination >5°). The alignment phase of OT resulted in ABH loss. The highest ABH loss in the maxilla was observed on the buccal side in the 'Proclination-high' and was 0.71 mm. ABH loss by 1.1 mm was observed in the mandible on the lingual side in the 'Retroinclination' group. The most significant changes in BT by up to 2 mm were observed at levels 6, 8 and 9 mm and these changes exhibited a moderate to strong correlation with the alterations in the inclination of individual incisors. At levels 2, 3 and 4 mm, the highest decrease in BT by up to 0.83 mm was observed on the palatal side of upper incisors in the 'Proclination-high' group. CONCLUSION The direction and amount of tooth inclination partially determine changes in the bone parameters during the alignment phase.
