Unpacking the perceptions and experiences of student facilitators in interprofessional education: a qualitative study. MEDICAL EDUCATION ONLINE 2024; 29:2330257. [PMID: 38493489 PMCID: PMC10946269 DOI: 10.1080/10872981.2024.2330257] [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: 10/16/2023] [Accepted: 03/08/2024] [Indexed: 03/19/2024]
Abstract
Enhancing health professional students' effective learning and collaborative practice requires a deep understanding of strategies for facilitating interprofessional learning. While faculty members and clinical preceptors are recognized as facilitators in interprofessional education (IPE), there is limited knowledge about the impact of student facilitators' engagement in IPE. Accordingly, this study aims to explore the perceptions and experiences of student facilitators in IPE. Thirteen student facilitators were recruited to lead an interprofessional learning program, and they were subsequently invited to participate in one-on-one interviews. An interview guide was developed to explore their motivations, expectations, engagement, effectiveness, and achievements in IPE facilitation. Thematic analysis was conducted using MAXQDA software to analyze the student facilitators' experiences and perceptions. Eight interviewees from various disciplines, including Medicine, Nursing, Pharmacy, Speech and Hearing Sciences, and Social Work, took part in the study. The findings revealed that student facilitators highly valued their IPE facilitation experience, which aligned with their expectations and led to the creation of social networks, increased confidence, improved understanding of other professions, and the development of lifelong skills. Furthermore, the student facilitators demonstrated cognitive and social congruence by establishing a relaxed learning environment, displaying empathetic and supportive behaviors, and using inclusive language to engage IPE learners in group discussions. This study provides a comprehensive understanding of the role of student facilitators in IPE, contributing to the evolving literature on IPE. A conceptual framework was developed to explore the entire facilitation experience, encompassing the motivations and expectations of student facilitators, their engagement and effectiveness, and the observed achievements. These findings can inform the development of peer teaching training in IPE and stimulate further research in identifying relevant facilitator competencies for optimal delivery of IPE.

Abstract
PURPOSE Phenomenology is a branch of philosophy that focuses on human lived experience. Illness including dental diseases can affect this living experience. Within the dental literature, there is very little reported on the use of phenomenology compared to other healthcare sciences. Hence, the aim was to review the literature and provide an overview of various applications of phenomenology in dental research. METHODS This study was a narrative review using literature in the last 10 years identified by web-based search on PubMed and Scopus using keywords. A total of 33 articles that were closely related to the field and application in dentistry were included. The methodology, main results, and future research recommendations, if applicable, were extracted and reviewed. RESULTS The authors in this study had identified several areas such as orofacial pain and pain control research, dental anxiety, dental education, oral healthcare perceptions and access, living with dental diseases and dental treatment experience in which the phenomenological method was used to gain an in-depth understanding of the topic. CONCLUSIONS There are several advantages of using the phenomenological research method, such as the small sample size needed, the diverse and unique perspective that can be obtained and the ability to improve current understanding, especially from the first-person perspective.

Abstract
The objective of this research was to evaluate the practice trends, clinical services and job satisfaction of dental therapists in Canada. Licenced Canadian dental therapists were recruited to participate in this cross-sectional study. A total of 124 dental therapists completed the survey (~68% response rate), with 57.3% of respondents being over the age of 50. Most respondents were actively engaged in full-time clinical practice in private dental offices. Indigenous dental therapists were significantly more likely to work outside of private dental offices providing care for Indigenous communities. Just over half of respondents were compensated by an annual salary, with the highest proportion of full-time practitioners earning between $75,000 and $99,000 per year. Dental therapists who were active in clinical practice performed a wide range of preventive, diagnostic, and treatment services consistent with their scope of practice. This research demonstrates that Canadian dental therapists are highly engaged and satisfied with their profession. Dental therapists can facilitate improved access to oral health care in less accessible areas of Canada; however, compensation packages and incentives to work in these less accessible areas must be addressed, as well as legal and regulatory requirements to ensure that dental therapists are licenced providers throughout Canada.

Abstract
Computer-aided design-computer-aided manufacturing (CAD-CAM) systems have been widely used as a fabrication method for restorations because of their high efficiency and accuracy, which significantly reduces fabrication time. However, molars with insufficient clearance or short clinical crown lengths require retention holes or grooves on the preparation, making it difficult to replicate the shapes with the CAM milling system. In these cases, restorations using the lost-wax method are selected. This article focuses on one-piece endodontic crowns (endocrowns) fabricated with a CAD-CAM system (CAD-CAM endocrowns), in which their posts and crowns are integrated. Articles from July 2012 to August 2023 were searched in PubMed with the keyword "endocrown". This review discusses the application of CAD-CAM endocrowns to molars from the viewpoint of model experiment (fracture resistance, adaptation) and clinical research. This technique, which allows margins and internal gaps to be set within the clinically acceptable range, is reported to be an effective way of restoring molars with high survival rates in clinical research.

Abstract
It is increasingly recognized that an important step towards improving overall health is to accurately measure biomarkers of health from the molecular activities prevalent in the oral cavity. We present a general methodology for computationally quantifying the activity of microbial functional pathways using metatranscriptomic data. We describe their implementation as a collection of eight oral pathway scores using a large salivary sample dataset (n = 9350), and we evaluate score associations with oropharyngeal disease phenotypes within an unseen independent cohort (n = 14,129). Through this validation, we show that the relevant oral pathway scores are significantly worse in individuals with periodontal disease, acid reflux, and nicotine addiction, compared with controls. Given these associations, we make the case to use these oral pathway scores to provide molecular health insights from simple, non-invasive saliva samples, and as molecular endpoints for actionable interventions to address the associated conditions.

Salivary biomarkers for early detection of oral squamous cell carcinoma (OSCC) and head/neck squamous cell carcinoma (HNSCC): A systematic review and network meta-analysis. JAPANESE DENTAL SCIENCE REVIEW 2024; 60:32-39. [PMID: 38204964 PMCID: PMC10776379 DOI: 10.1016/j.jdsr.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 09/21/2023] [Accepted: 10/26/2023] [Indexed: 01/12/2024] Open
Abstract
Oral cancer became a very common condition. WHO estimates that there are 4 cases of lip and oral cavity cancer for every 100,000 people worldwide. The early diagnosis of cancers is currently a top focus in the health sector. Recent systematic reviews and meta-analyses have identified promising biomarkers for early detection in several original research investigations. However, it is still unclear the quality of these evidence and which biomarker performs the best in terms of early detection. Therefore, the objective was, to map the methodological and reporting quality of available oral squamous cell carcinoma (OSCC) or head/neck squamous cell carcinoma (HNSCC) systematic reviews and meta-analysis. Secondly, to evaluate diagnostic accuracy of salivary biomarkers for common craniofacial cancers and to compare the diagnostic value of different salivary biomarkers. PubMed, Scopus, Web of Science, Embase and Cochrane Library electronic databases were used to map the methodological and reporting quality of the systematic reviews and meta-analysis conducted on the HNSCC, OSCC using the AMSTAR-2 checklist. The inclusion criteria were systematic reviews and meta-analysis published in the topic of HNSCC and OSCC biomarkers. Exclusion criteria were no animal studies; original primary studies, due to limitation of competency in other languages articles with language other than English were excluded. The sensitivity and specificity were calculated for salivary biomarkers and ranked according to network meta-analysis principles. A total of N = 5893 patients were included from four meta-analysis studies. All together, these included n = 37 primary studies. n = 94 biomarkers were pooled from these four meta-analyses and categorised into the stages at which they were detected (I-IV). In OSCC, Chemerin and MMP-9 displayed the highest sensitivity, registering 0.94 (95% CI 0.78, 1.00) and a balanced accuracy of 0.93. Phytosphingosine closely followed, with a sensitivity of 0.91 (95% CI 0.68, 0.99) and a balanced accuracy of 0.87. For HNSCC, the top three biomarkers are Actin, IL-1β Singleplex, and IL-8 ELISA. Actin leads with a sensitivity of 0.91 (95% CI 0.68-0.99), a specificity of 0.67, and an overall accuracy of 0.79. Subsequently, IL-1β Singleplex exhibits a sensitivity of 0.62 (95% CI 0.30-0.88), a specificity of 0.89, and an accuracy of 0.75, followed by IL-8 ELISA with a sensitivity of 0.81 (95% CI 0.54-0.97), a specificity of 0.59, and an accuracy of 0.70. In conclusion, there was highest sensitivity for MMP-9 and chemerin salivary biomarkers. There is need of further more studies to identify biomarkers for HNSCC and OSCC.

Abstract
Most reports on duplicate dentures are introduction to fabrication methods or clinical case reports. Only a few studies have verified their clinical effectiveness; hence, evidence to construct useful clinical guidelines for duplicate denture use is lacking. This review aimed to comprehensively investigate reports on duplicate dentures to accumulate evidences that will contribute to the formulation of clinical practice guidelines. Duplicate dentures are effectively used for impression making and bite registration when fabricating new dentures, thereby reducing the number of clinic visits and treatment time. Duplicate denture can also be used as temporary or new dentures. Older people in whom various adaptive abilities have declined, may find it difficult to adjust to new dentures and experience stress, even if the shape is appropriate. Duplicate dentures, which reproduces the shape of old dentures that they are used to, have the advantage of being more familiar to older people and less stressful. When manufacturing duplicate dentures, digital methods such as milling and three-dimensional printing are superior to conventional methods regarding working time and cost. A notable advantage of the digital method is that the denture shape can be saved as digital data, and the denture can be easily duplicated if lost.

Neural Regen Res 2024; 19:2613-2625. [PMID: 38595280 PMCID: PMC11168506 DOI: 10.4103/nrr.nrr-d-23-01677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 12/25/2023] [Accepted: 01/25/2024] [Indexed: 04/11/2024] Open
Abstract
The search for reliable and easily accessible biomarkers in Parkinson's disease is receiving a growing emphasis, to detect neurodegeneration from the prodromal phase and to enforce disease-modifying therapies. Despite the need for non-invasively accessible biomarkers, the majority of the studies have pointed to cerebrospinal fluid or peripheral biopsies biomarkers, which require invasive collection procedures. Saliva represents an easily accessible biofluid and an incredibly wide source of molecular biomarkers. In the present study, after presenting the morphological and biological bases for looking at saliva in the search of biomarkers for Parkinson's disease, we systematically reviewed the results achieved so far in the saliva of different cohorts of Parkinson's disease patients. A comprehensive literature search on PubMed and SCOPUS led to the discovery of 289 articles. After screening and exclusion, 34 relevant articles were derived for systematic review. Alpha-synuclein, the histopathological hallmark of Parkinson's disease, has been the most investigated Parkinson's disease biomarker in saliva, with oligomeric alpha-synuclein consistently found increased in Parkinson's disease patients in comparison to healthy controls, while conflicting results have been reported regarding the levels of total alpha-synuclein and phosphorylated alpha-synuclein, and few studies described an increased oligomeric alpha-synuclein/total alpha-synuclein ratio in Parkinson's disease. Beyond alpha-synuclein, other biomarkers targeting different molecular pathways have been explored in the saliva of Parkinson's disease patients: total tau, phosphorylated tau, amyloid-β1-42 (pathological protein aggregation biomarkers); DJ-1, heme-oxygenase-1, metabolites (altered energy homeostasis biomarkers); MAPLC-3beta (aberrant proteostasis biomarker); cortisol, tumor necrosis factor-alpha (inflammation biomarkers); DNA methylation, miRNA (DNA/RNA defects biomarkers); acetylcholinesterase activity (synaptic and neuronal network dysfunction biomarkers); Raman spectra, proteome, and caffeine. Despite a few studies investigating biomarkers targeting molecular pathways different from alpha-synuclein in Parkinson's disease, these results should be replicated and observed in studies on larger cohorts, considering the potential role of these biomarkers in determining the molecular variance among Parkinson's disease subtypes. Although the need for standardization in sample collection and processing, salivary-based biomarkers studies have reported encouraging results, calling for large-scale longitudinal studies and multicentric assessments, given the great molecular potentials and the non-invasive accessibility of saliva.

Abstract
The drive for minimally invasive endodontic treatment strategies has shifted focus from technically complex and destructive root canal treatments towards more conservative vital pulp treatment. However, novel approaches to maintaining dental pulp vitality after disease or trauma will require the development of innovative, biologically-driven regenerative medicine strategies. For example, cell-homing and cell-based therapies have recently been developed in vitro and trialled in preclinical models to study dental pulp regeneration. These approaches utilise natural and synthetic scaffolds that can deliver a range of bioactive pharmacological epigenetic modulators (HDACis, DNMTis, and ncRNAs), which are cost-effective and easily applied to stimulate pulp tissue regrowth. Unfortunately, many biological factors hinder the clinical development of regenerative therapies, including a lack of blood supply and poor infection control in the necrotic root canal system. Additional challenges include a need for clinically relevant models and manufacturing challenges such as scalability, cost concerns, and regulatory issues. This review will describe the current state of bioactive-biomaterial/scaffold-based engineering strategies to stimulate dentine-pulp regeneration, explicitly focusing on epigenetic modulators and therapeutic pharmacological inhibition. It will highlight the components of dental pulp regenerative approaches, describe their current limitations, and offer suggestions for the effective translation of novel epigenetic-laden bioactive materials for innovative therapeutics.

Abstract
The physicochemical properties of grafting materials affect the quality of the osteointegration, resorption rate, and the new bone (NB) formation. This study assessed the physicochemical properties and integration of a low temperature deproteinized bovine bone xenograft (BBX), referred to as optimized MoaBone® (OMB). This novel BBX was physiochemically characterized both pre and post chemical bleaching and sterilization by gamma irradiation. OMB was compared to two commercial BBX; Bio-Oss® (BO) and MoaBone® (MB) using a rabbit cranial model. Residual graft and NB were quantified using histology and micro-computed tomography. Results showed that chemical treatment and gamma irradiation had limited effect on the surface texture. A significant decrease in the collagen content was detected post chemical treatment and in the carbonate content post gamma irradiation. There was no evidence of inflammatory infiltrate, necrosis, or connective tissue encapsulation, and a significant increase of NB in all grafted sites as compared to untreated defects could be observed. However, there was no statistically significant difference between the grafted sites. We conclude that chemical treatment and terminal sterilization strongly impact the final graft's properties. OMB graft showed equivalence with BO for in vivo bone formation and potentially results in lower levels of graft retention.

J Biomed Mater Res A 2024; 112:1412-1423. [PMID: 38461494 DOI: 10.1002/jbm.a.37706] [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: 11/29/2023] [Revised: 02/21/2024] [Accepted: 02/29/2024] [Indexed: 03/12/2024]
Abstract
Dental enamel is a mineralized extracellular matrix, and enamel defect is a common oral disease. However, the self-repair capacity of enamel is limited due to the absence of cellular components and organic matter. Efficacy of biomimetic enamel mineralization using calcium phosphate ion clusters (CPICs), is an effective method to compensate for the limited self-healing ability of fully developed enamel. Preparing and stabilizing CPICs presents a significant challenge, as the addition of certain stabilizers can diminish the mechanical properties or biosafety of mineralized enamel. To efficiently and safely repair enamel damage, this study quickly prepared CPICs without stabilizers using the atomization method. The formed CPICs were evenly distributed on the enamel surface, prompting directional growth and transformation of hydroxyapatite (HA) crystals. The study revealed that the mended enamel displayed comparable morphology, chemical composition, hardness, and mechanical properties to those of the original enamel. The approach of repairing dental enamel by utilizing ultrasonic nebulization of CPICs is highly efficient and safe, therefore indicating great promise.

Association between CDK4/6 inhibitors and drug-related osteonecrosis of the jaw: A pharmacoepidemiological study using the FDA Adverse Events Reporting System. Int J Cancer 2024; 155:849-853. [PMID: 38619193 DOI: 10.1002/ijc.34962] [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: 01/19/2024] [Revised: 03/07/2024] [Accepted: 03/25/2024] [Indexed: 04/16/2024]
Abstract
The most common toxicities associated with cyclin-dependent kinase (CDK) 4/6 inhibitor therapy include decreased leukopenia and neutropenia due to the inhibition of CDK6 of leukocyte and neutrophil precursors in bone marrow. These hematological toxicities are more commonly observed with palbociclib administration than with abemaciclib administration, which is approximately 13 times more selective against CDK4 than CDK6. Thus, even though both successfully inhibit CDK4/6, the side effects of palbociclib and abemaciclib differ due to differences in selectivity. Recent reports have suggested an association between palbociclib and medication-related osteonecrosis of the jaw; however, reports on this association are inconsistent. This study investigated the potential association of palbociclib and abemaciclib with MRONJ using the FAERS. Signals of "Osteonecrosis of jaw" were detected only in females using palbociclib (cROR025: 2.08). Other signals detected included stomatitis-related adverse events with abemaciclib and intraoral soft tissue damage and infection with palbociclib. As previous exploratory studies have reported MRONJ signals for bisphosphonates and denosumab, we calculated the aROR for palbociclib-induced osteonecrosis of the jaw using concomitant bisphosphonates and denosumab as covariates. A signal was detected even after adjusting for sex, age, and concomitant medications as covariates (aROR0025: 5.74). A proper understanding of the differences in CDK selectivity is necessary for the appropriate use of CDK4/6 inhibitors. To the best of our knowledge, this is the first report on CDK4/6 inhibitors and drug-related osteonecrosis of the jaw. We believe that these results will offer new insights into adverse events related to the use of CDK4/6 inhibitors, and may aid in the proper use of CDK4/6 inhibitors.

Abstract
OBJECTIVES To characterize mouth-opening muscular performance (MOMP) in adults and elderly individuals with dysphagia and healthy controls. METHODS We searched the PubMed, EMBASE, CINAHL, Cochrane, Scopus, and Web of Science databases from inception to Jan. 26, 2023. Two independent researchers considered the titles, abstracts, and full texts of potentially eligible papers from 1451 search results. Twenty-five studies that evaluated mouth-opening maximal strength (MOMS) in healthy adults, elderly individuals, and patients with dysphagia met the inclusion criteria. RESULTS We found comparable, reliable values with significant sex differences in maximal mouth opening strength (MMOS) in the meta-analysis for healthy elderly patients (females 5.31 ± 0.47 kg vs. males 7.04 ± 0.70 kg; mean difference of 0.84 kg). Age has also emerged as an essential factor in reducing strength. There was a significant reduction in the MMOS score in the only study that compared dysphagic individuals to healthy elderly individuals. In another study, the MMOS score was comparable to the meta-analysis of healthy elderly individuals. CONCLUSIONS Both sex and age play significant roles in the MMOS. There is no reliable data on the normal mouth-opening strength and endurance of healthy adults, patients with dysphagia, or individuals with other relevant clinical problems.

Abstract
Patients treated for oral cancer, may experience restricted mouth opening (trismus). Barriers such as cost have limited the utilization of traditional jaw stretching devices, and consequently, patients experience problems with swallowing, oral care, communication, and cancer surveillance. The safety and efficacy of Restorabite™, a new device designed to overcome these barriers, is evaluated prospectively over 12 months. This phase II investigator-led trial included patients with chronic trismus underwent 10-weeks of trismus therapy using Restorabite™. Safety, adherence, changes in mouth opening, and patient-reported outcomes are presented. 114/120 participants with trismus completed the intervention, and 104 had their progress monitored for 12 months. Thirteen participants withdrew due to tumour recurrence. At the completion of the intervention, mouth opening improved by 10.4 mm (p < .001). This increased to 13.7 mm at 12 months (p < .001). Patient reported outcome all significantly improved and 47 participants were no longer classified as having trismus. There were no serious treatment related adverse events. In patients with trismus following head and neck cancer treatment, a 10-week programme of jaw stretching exercises using Restorbite™ safely improves mouth opening and associated quality of life outcomes with high adherence and the benefits are maintained for 12-months.

Abstract
Th17 cell plasticity is crucial for development of autoinflammatory disease pathology. Periodontitis is a prevalent inflammatory disease where Th17 cells mediate key pathological roles, yet whether they exhibit any functional plasticity remains unexplored. We found that during periodontitis, gingival IL-17 fate-mapped T cells still predominantly produce IL-17A, with little diversification of cytokine production. However, plasticity of IL-17 fate-mapped cells did occur during periodontitis, but in the gingiva draining lymph node. Here, some Th17 cells acquired features of Tfh cells, a functional plasticity that was dependent on IL-6. Notably, Th17-to-Tfh diversification was important to limit periodontitis pathology. Preventing Th17-to-Tfh plasticity resulted in elevated periodontal bone loss that was not simply due to increased proportions of conventional Th17 cells. Instead, loss of Th17-to-Tfh cells resulted in reduced IgG levels within the oral cavity and a failure to restrict the biomass of the oral commensal community. Thus, our data identify a novel protective function for a subset of otherwise pathogenic Th17 cells during periodontitis.

Abstract
BACKGROUND Radiomics is a rapidly growing field used to leverage medical radiological images by extracting quantitative features. These are supposed to characterize a patient's phenotype, and when combined with artificial intelligence techniques, to improve the accuracy of diagnostic models and clinical outcome prediction. OBJECTIVES This review aims at examining the application areas of artificial intelligence-based radiomics (AI-based radiomics) for the management of head and neck cancer (HNC). It further explores the workflow of AI-based radiomics for personalized and precision oncology in HNC. Finally, it examines the current challenges of AI-based radiomics in daily clinical oncology and offers possible solutions to these challenges. METHODS Comprehensive electronic databases (PubMed, Medline via Ovid, Scopus, Web of Science, CINAHL, and Cochrane Library) were searched following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The quality of included studies and their risk of biases were evaluated using the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD)and Prediction Model Risk of Bias Assessment Tool (PROBAST). RESULTS Out of the 659 search hits retrieved, 45 fulfilled the inclusion criteria. Our review revealed that the application of AI-based radiomics model as an ancillary tool for improved decision-making in HNC management includes radiomics-based cancer diagnosis and radiomics-based cancer prognosis. The radiomics-based cancer diagnosis includes tumor staging, tumor grading, and classification of malignant and benign tumors. Similarly, radiomics-based cancer prognosis includes prediction for treatment response, recurrence, metastasis, and survival. In addition, the challenges in the implementation of these models for clinical evaluations include data imbalance, feature engineering (extraction and selection), model generalizability, multi-modal fusion, and model interpretability. CONCLUSION Considering the highly subjective and interobserver variability that is peculiar to the interpretation of medical images by expert clinicians, AI-based radiomics seeks to offer potentially useful quantitative information, which is not visible to the human eye or unintentionally often remain ignored during clinical imaging practice. By enabling the extraction of this type of information, AI-based radiomics has the potential to revolutionize HNC oncology, providing a platform for more personalized, higher quality, and cost-effective care for HNC patients.

Abstract
Odontogenic infections are a broad group of head and neck conditions that arise from the teeth and surrounding periodontium. These largely preventable infections disproportionately affect members of ethnic and racial minorities and low-income/uninsured groups, and result in significant costs to our health care system. Left untreated, odontogenic infections can spread to deep spaces of the head and neck and can result in life-threatening complications. The mainstay of treatment includes timely treatment of the affected teeth. These infections are a global public health concern that could be diminished with improved access to routine dental care.

Abstract
OBJECTIVES The molecular mechanisms behind orthodontic tooth movements (OTM) were investigated by clarifying the role of chemical messengers released by cells. METHODS Using the Cochrane library, Google scholar, and PubMed databases, a literature search was conducted, and studies published from 1984 to 2024 were considered. RESULTS Both bone growth and remodeling may occur when a tooth is subjected to mechanical stress. These chemicals have a significant effect on the stimulation and regulation of osteoblasts, osteoclasts, and osteocytes during alveolar bone remodeling. This regulation can take place in pathological conditions, such as periodontal diseases, or during OTM alone. This comprehensive review outlines key molecular mechanisms underlying OTM and explores various clinical assumptions associated with specific molecules and their functional domains during this process. Furthermore, clinical applications of certain molecules such as relaxin, prostaglandin E (PGE), and interleukin-1β (IL-1β) in accelerating OTM have been reported. Our findings underscore the existing gap between OTM clinical applications and basic research investigations. CONCLUSION A comprehensive understanding of orthodontic treatment is enriched by insights into biological systems. We reported the activation of osteoblasts, osteoclast precursor cells, osteoclasts, and osteocytes in response to mechanical stress, leading to targeted cellular and molecular interventions and facilitating rapid and regulated alveolar bone remodeling during tooth movement. Despite the shortcomings of clinical studies in accelerating OTM, this review highlights the crucial role of biological agents in this process and advocates for prioritizing high-quality human studies in future research to gain further insights from clinical trials.

Abstract
INTRODUCTION Dental caries continues to be a public healthcare problem due to its high prevalence and morbidity. It was proposed to evaluate caries indicators in relation to healthcare access and hygienic-dietary habits in Spanish preschoolers. MATERIALS AND METHODS A cross-sectional study was carried out on a random sample consisting of 343 patients ranging from 3 to 5 years of age in the primary care setting, the main measurements were: dental care access, hygienic-dietary habits, and caries registration according to WHO criteria. RESULTS The prevalence of caries was 35.3% and mean ± standard deviation (SD) dft was 1.51 ± 2.93. Preschoolers who had ever visited the dentist had a higher dft occurrence than those who had never attended the dentist. The lower prevalence of caries was significantly associated with the frequency of two daily brushings versus non-daily brushing (p = 0.007; 25.3% vs. 47.1%) and was 10.7% lower in patients who had the habit of night brushing (p = 0.041). The consumption of sugary liquids between meals implied a higher dft index. CONCLUSIONS The high prevalence of early childhood caries and the dental care access associated with poor oral health suggest the need to implement a multidisciplinary oral healthcare program that involves both healthcare and dental healthcare professionals in Primary Health Care Units without forgetting the participation of the community and local administrations.

The LOTUS 10-year retrospective cohort study. Community Dent Oral Epidemiol 2024; 52:413-423. [PMID: 38191778 DOI: 10.1111/cdoe.12930] [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: 09/05/2023] [Revised: 11/10/2023] [Accepted: 11/19/2023] [Indexed: 01/10/2024]
Abstract
OBJECTIVE To pragmatically assess the clinical and cost-effectiveness of water fluoridation for preventing dental treatment and improving oral health in a contemporary population of adults and adolescents, using a natural experiment design. METHODS A 10-year retrospective cohort study (2010-2020) using routinely collected NHS dental treatment claims data. Participants were patients aged 12 years and over, attending NHS primary dental care services in England (17.8 million patients). Using recorded residential locations, individuals exposed to drinking water with an optimal fluoride concentration (≥0.7 mg F/L) were matched to non-exposed individuals using propensity scores. Number of NHS invasive dental treatments, DMFT and missing teeth were compared between groups using negative binomial regression. Total NHS dental treatment costs and cost per invasive dental treatment avoided were calculated. RESULTS Matching resulted in an analytical sample of 6.4 million patients. Predicted mean number of invasive NHS dental treatments (restorations 'fillings'/extractions) was 3% lower in the optimally fluoridated group (5.4) than the non-optimally fluoridated group (5.6) (IRR 0.969, 95% CI 0.967, 0.971). Predicted mean DMFT was 2% lower in the optimally fluoridated group (IRR 0.984, 95% CI 0.983, 0.985). There was no difference in the predicted mean number of missing teeth per person (IRR 1.001, 95% CI 0.999, 1.003) and no compelling evidence that water fluoridation reduced social inequalities in dental health. Optimal water fluoridation in England 2010-2020 was estimated to cost £10.30 per person (excludes initial set-up costs). NHS dental treatment costs for optimally fluoridated patients 2010-2020 were 5.5% lower, by £22.26 per person (95% CI -£21.43, -£23.09). CONCLUSIONS Receipt of optimal water fluoridation 2010-2020 resulted in very small positive health effects which may not be meaningful for individuals. Existing fluoridation programmes in England produced a positive return on investment between 2010 and 2020 due to slightly lower NHS dental care utilization. This return should be evaluated against the projected costs and lifespan of any proposed capital investment in water fluoridation, including new programmes.

Abstract
Empirical evidence has shown that individuals from minority ethnic communities have been at an increased risk of COVID-19 infections and adverse clinical outcomes including hospitalization, intensive care unit admission, and mortality. The COVID-19 vaccine has been heralded as key in ending the global pandemic. However, evidence suggests that although minority ethnic communities have been disproportionately affected by COVID-19, vaccine delivery to these communities has been poor. A barrier to the vaccine uptake has been health information. Health information is an important variable in the health decision-making process. Lack of or wrong health information has serious implications. Health information leads to better understanding of personal health and appropriate utilization of health services and consequently improves an individual's health outcomes. This study sought to explore the health information seeking practices among participants from a Black ethnic minority community in the UK. This study interviewed six Black Africans from the UK. The study explored and highlighted the thoughts, perceptions, and experiences of the participants while health information seeking. This study found challenges in health information access, assumptions about health information and feelings of being dismissed, and an information void. Participants acknowledge that there is a lot that could be done to improve their health information experiences. Targeted health information and measures such as cultural sensitivity and competency could be important in improving health information seeking, not just for Black Africans but all ethnic minorities in the UK.

Abstract
INTRODUCTION Erosive tooth wear (ETW) has been gaining attention due to its high prevalence. However, ETW clinical diagnosis is difficult and may go unnoticed by many professionals. The present study aimed to develop, implement and evaluate a theoretical-practical training using active methodologies in the development of undergraduate students' skills for the diagnosis of ETW compared to the traditional teaching method. MATERIALS AND METHODS This randomized controlled study involved two parallel groups: control group (n = 22), with learning based only on theoretical content and test group (n = 24), learning by theoretical-practical activity mediated by monitors/tutors. The theoretical class covered the current concepts of ETW, aetiology, diagnosis, use of the BEWE index, prevention and treatment. The practical training included exercises and discussions based on the diagnosis using BEWE scores of a collection of images and extracted teeth. To evaluate the efficacy of the teaching-learning methods, a theoretical multiple-choice questionnaire and a practical test using images and extracted teeth were applied. The outcome was the number of correct answers. Groups were compared by Mann-Whitney (theoretical knowledge) and T tests (practical ability in diagnosis) (p < .05). RESULTS There was no significant difference between groups in the theoretical evaluation (p = .866). The test group showed higher ability to diagnose ETW lesions compared to the control group in the practical tests (p = .001). The performance of ETW diagnosis was similar when images were used in comparison to extracted teeth (p = .570). CONCLUSION The practical activity associated with theoretical classes can be a promising strategy to improve the development of undergraduate students' skills in the diagnosis of ETW.

[PMID: 38520077 DOI: 10.1111/eje.13004] [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: 03/28/2023] [Revised: 01/18/2024] [Accepted: 02/16/2024] [Indexed: 03/25/2024]
Abstract
Dental education continuously strives to provide students with positive and meaningful learning experiences. Developing or improving a curriculum usually encompasses three main phases: design, implementation, and evaluation. Most research on curriculum development in dental education has focused on the last two phases. Our commentary addresses this gap by describing a new model for curriculum design that effectively guided the design phase of the complete overhaul of the four-year Doctor of Dental Surgery curriculum at the School of Dentistry, University of Alberta. Built on the strengths of pre-existing curriculum design models, the new model provided enough structure and rigour to support the complexity required during a complete curriculum redesign whilst still allowing sufficient consultation and flexibility to encourage stakeholder engagement. The steps of the new 4P's model (preparation, planning, prototyping, and piloting) and main actions within each step are described. Challenges observed in each step and strategies to address them are reported. Other institutions embarking on renewing or redesigning a curriculum at a program level may benefit from using a curriculum design process similar to the 4P's model. Recommendations are discussed including the inclusion of educational consultants in the curriculum renewal committee, the importance of a leadership that effectively supports curriculum reform, purposeful engagement of stakeholders during each step of the design phase and ensuring that project and change management occur concurrently.

Abstract
OBJECTIVES To investigate the relationship between socioenvironmental sugar promotion and geographical inequalities in the prevalence of dental caries amongst 5-year-olds living across small areas within England. METHODS Ecological data from the National Dental Epidemiology Programme (NDEP) 2018-2019, comprising information on the percentage of 5-year-olds with tooth decay (≥1 teeth that are decayed into dentine, missing due to decay, or filled), and untreated tooth decay (≥1 decayed but untreated teeth), in lower-tier local authorities (LAs) of England. These were analysed for association with a newly developed Index of Sugar-Promoting Environments Affecting Child Dental Health (ISPE-ACDH). The index quantifies sugar-promoting determinants within a child's environment and provides standardized scores for the index, and its component domains that is, neighbourhood-, school- and family-environment, with the highest scores representing the highest levels of sugar promotion in lower-tier LAs (N = 317) of England. Linear regressions, including unadjusted models separately using index and each domain, and models adjusted for domains were built for each dental outcome. RESULTS Participants lived across 272 of 317 lower-tier LAs measured within the index. The average percentage of children with tooth decay and untreated tooth decay was 22.5 (SD: 8.5) and 19.6 (SD: 8.3), respectively. The mean index score was (0.1 [SD: 1.01]). Mean domain scores were: neighbourhood (0.02 [SD: 1.03]), school (0.1 [SD: 1.0]), and family (0.1 [SD: 0.9]). Unadjusted linear regressions indicated that the LA-level percentage of children with tooth decay increased by 5.04, 3.71, 4.78 and 5.24 with increased scores of the index, and neighbourhood, school and family domains, respectively. An additional model, adjusted for domains, showed that this increased percentage predicted by neighbourhood domain attenuated to 1.37, and by family domain it increased to 6.33. Furthermore, unadjusted models indicated that the LA-level percentage of children with untreated tooth decay increased by 4.72, 3.42, 4.45 and 4.97 with increased scores of the index, and neighbourhood, school, and family domains, respectively. The model, adjusted for domains, showed that this increased percentage predicted by neighbourhood domain attenuated to 1.24 and by family domain rose to 6.47. School-domain was not significantly associated with either outcome in adjusted models. CONCLUSIONS This study reveals that socioenvironmental sugar promotion, particularly within neighbourhood- and family-environments, may contribute to geographical inequalities in dental caries in children. Further research involving data on individual-level dental outcomes and confounders is required.

Abstract
The COVID-19 pandemic placed a significant burden on healthcare resources, limiting care to emergent and essential services only. The objective of this study was to describe the effect of the COVID-19 pandemic on the diagnosis and progression of oral cancer lesions in Montreal, Canada. A retrospective analysis of health records was performed. Patients presenting for a new oncology consultation for an oral lesion suspicious for cancer between March 2018 and March 2022, within the Department of Oral and Maxillofacial Surgery of the McGill University Health Center, were included. Data was collected on sociodemographic characteristics, oral cancer risk behaviors of study participants, oral cancer delays, tumor characteristics, and clinical management. A total of 190 patients were included, 91 patients from the pre-pandemic period and 99 from the pandemic period. The demographic characteristics of the patients in the two periods were comparable. There was no significant difference in the patient, professional, or treatment delay between the two periods. There was a non-significant increase in pathologic tumor size during the pandemic, but the pathologic staging and postoperative outcomes were comparable to those of the pre-pandemic cohort. The results indicate that emergent care pathways for oral cancer treatment were efficiently maintained despite the pandemic shutdown of services.

Abstract
OBJECTIVES The field of dentistry is characterised by its substantial energy consumption and resource utilisation, resulting in a notable ecological footprint. Thus, sustainability in dentistry is an important but underresearched concern. The influence of public pressure on sustainability has been extensively studied across other industries; nevertheless, there is a dearth of research examining its impact on the dental sector specifically in Saudi Arabia. The current study conducted the first-ever survey in Saudi Arabia to investigate the prevailing attitudes with regard to sustainable dentistry amongst the general population of the country. METHODS This was an online cross-sectional observational survey conducted in Riyadh, Saudi Arabia. A self-administered online questionnaire was distributed to adults aged 18 years and older, of both genders, from March to April 2023. The study obtained appropriate ethical approval. RESULTS Participants expressed a positive attitude with regard to sustainable dentistry and demonstrated their openness regarding compromising in terms of time, convenience, cost, and even the appearance of their teeth in order to minimise the environmental impact resulting from dental procedures. It is also evident that a correlation exists between gender-associated beliefs and proenvironmental behaviour, particularly in the context of sustainable dentistry and related environmental intentions in Saudi Arabia. CONCLUSIONS The findings of this study represent an important complement to the existing sustainability knowledge and understanding in dentistry, which will be helpful for policymakers as well as dental professionals to develop or modify policy, regulation, and professional curriculum.

Abstract
In daily rheumatology practice, systemic sclerosis is primarily regarded as a potentially life-threatening disease characterized by fibrosis of various organs. Therefore, other manifestations, such as orofacial involvement, are often not of primary concern. Furthermore, due to its rarity, the disease might not be well known by dentists, which contrasts with the increased risk of various problems in the oral cavity. Periodontitis in particular is a known risk factor for morbidity and mortality and is associated with various systemic diseases. The risk of periodontitis appears to be increased in patients with systemic sclerosis, but little is known about the gender-specific differences. This study aims to elucidate the health-conscious behaviour of patients, their dental care and the risk of periodontitis with regard to gender-specific differences. This descriptive study of the Interdisciplinary Centre of Rheumatic Diseases (INDIRA) in collaboration with the Department of Orthodontics at the University Hospital of Tuebingen, Germany, examined the data of 148 patients with systemic sclerosis with regard to their oral health using a questionnaire and evaluating the risk of periodontitis with the DG Paro self-assessment score in this cohort. Among the participating patients, 90% reported regular visits to the dentist and good dental care. Nevertheless, more than half of the patients had missing teeth and problems opening their mouths. Sicca symptoms in the oral cavity were also common (40%). The risk of periodontitis among female participants was high (around 60%), and even higher among male study participants (around 80%). Gingival bleeding as a surrogate parameter for periodontitis was associated with salivary flow and the modified Rodnan skin score (mRSS). Despite a high awareness of dental health, we observed a high risk of periodontitis, especially in male patients with systemic sclerosis. In addition, the association between xerostomia and missing teeth as well as gingival bleeding and mRSS may indicate an increased risk in patients with a more progressive disease. We would therefore recommend regular dental consultations and careful oral hygiene for patients with systemic sclerosis in addition to the-more organ-focused-regular examinations of patients.

Abstract
BACKGROUND Extrinsic factors for erosive tooth wear (ETW) have been widely reported, but the intrinsic factors for wear remain unclear. OBJECTIVES The aim of this study was to evaluate the factors associated with the prevalence of ETW in patients with reflux oesophagitis (RO). To prevent severe ETW with RO, factors associated with severity of ETW were also evaluated. METHODS A total of 270 patients with RO were recruited. A modified tooth wear index was used to evaluate the prevalence and severity of ETW. Salivary secretion and buffering capacity were assessed prior to endoscopy. Subjects were asked to complete a medical condition and oral self-care questionnaire. Univariate and multivariate analyses were employed to identify factors collectively associated with the prevalence and severity of ETW. RESULTS A total of 212 cases were categorized as patients with ETW (148 with mild ETW and 64 with severe ETW). Multivariate analyses indicated that saliva secretion, severity of RO and proton pump inhibitor (PPI) resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. The odds ratio of saliva secretion and BMI were less than 1, meaning that higher saliva secretion resulted in a lower prevalence of ETW and lower BMI was associated with severe ETW. CONCLUSION Saliva secretion, severity of RO and PPI resistance were associated with the prevalence of ETW, whereas age, BMI and severity of RO were associated with the severity of ETW. Lower saliva secretion and BMI were significant factors for ETW.

Abstract
OBJECTIVES To investigate the transdentinal effects of surface reaction-type pre-reacted glass-ionomer (S-PRG) fillers on odontoblast-like cells. METHODS An eluate of S-PRG fillers was obtained by dissolving the particles in distilled water (1:1 m/v). Dentin discs with similar permeability were mounted into artificial pulp chambers and MDPC-23 cells were seeded on their pulpal surface. The occlusal surface was treated with (n = 10): ultrapure water (negative control - NC), hydrogen peroxide (positive control - PC), S-PRG eluate exposure for 1 min (S-PRG 1 min), or S-PRG filler eluate exposure for 30 min (S-PRG 30 min). After 24 h, cell viability (alamarBlue) and morphology (SEM) were evaluated. The extract obtained from transdentinal diffusion was applied to MDPC-23 pre-cultured in plates for another 24 h to evaluate viability (alamarBlue, 1, 3, and 7 days), gene expression of Col1a1, Alpl, Dspp, and Dmp1 (RT-qPCR, 1 and 7 days), and mineralization (Alizarin Red, 7 days). Data were analyzed with ANOVA (α = 5 %). RESULTS While S-PRG 1 min did not differ from NC, S-PRG 30 min reduced 17.9 % viability of cells from discs. S-PRG treatments resulted in low cell detaching from dentin, and the remaining cells exhibited typical morphology or minor cytoplasmic contraction. S-PRG 30 min slightly increased cell viability (6 %) 1 day after contact with the extract. S-PRG treatments upregulated the expression of the investigated genes, especially after 1 day. S-PRG 30 min stimulated mineralization activity by 39.7 %. CONCLUSIONS S-PRG filler eluate does not cause transdentinal cytotoxicity on odontoblast-like cells, and long-term exposure can stimulate their dentinogenic-related mineralization activity. SIGNIFICANCE The transdentinal elution of ions from S-PRG fillers is not expected to be harmful to the dental pulp and may exert bioactive effects by inducing dentin matrix deposition through the metabolism of underlying odontoblasts.

Abstract
OBJECTIVES To explore the risk factors for dental caries (DC) and tooth wear (TW) and assess their importance according to age in random French adult patients with >1 partial coronal restoration. METHODS The data stem from a prospective observational multicentre cross-sectional study and were collected through interviews and clinical examinations. The study involved 96 dentists from 76 hospital and private clinics and included 822 patients. The data analysed in three age groups (18-29, 30-59, and ≥ 60). Univariate logistic regressions were performed and predictions of DC or TW described using decision trees. RESULTS The study confirmed the major influences of oral hygiene, acceptable sugary/acidic beverage consumption and regular dental visits in reducing DC and TW. Further, it exposed age-related risk factors for DC such being a "new patient" and having an "excessive sugary/acidic beverage consumption" in the youngest adults, or "irregular dental visits" in middle-aged adults and in the oldest. CONCLUSIONS For appropriate preventive counselling, risk factor assessment should be extensive and age- and dental history-oriented because of unexpected age-related risk factors or risk factor combinations. CLINICAL SIGNIFICANCE These results are likely to make better-grounded new recommendations given to young adults since their first visits and throughout their dental clinical pathway.

Abstract
OBJECTIVES To evaluate the wear resistance of three additively manufactured dental crown materials (NextDent C&B MFH, Saremco print CROWNTEC and Bego VarseoSmile Crown) under two environmental conditions (dry and artificial saliva), two loads (49 N and 70 N) and two surface treatments (polished and glazed). METHODS A total of 120 specimens were divided into 24 groups and tested for wear under two loads (49 N and 70 N), surface treatment (polished or glazed), and environment (dry or submerged in artificial saliva). All samples underwent reciprocating wear testing at 1 Hz using a wear simulator, replicating 48 months of In Vivo conditions with a stainless-steel ball as the antagonist. The coefficient of friction (CoF), surface roughness, volumetric and vertical wear loss were measured and statistically analysed. Confocal microscopy assessed the surface properties of crown materials and the antagonists. RESULTS The NextDent material demonstrated the most homogenous wear, with relatively low vertical and volumetric loss across all groups (p < 0.004). NextDent and Bego materials performed similarly in artificial saliva regardless of the load type (p > 1.000). The CoF remained below 0.3 for all groups. All groups exhibited significant increases in surface roughness after testing, however, this did not correlate with an increase in the CoF. Confocal analysis revealed material deformities due to load and notable scratch marks on the stainless-steel antagonists. CONCLUSION It was found that all investigated addtively manufactured materials can be suggested for provisional use. Both vertical loss and volumetric loss results should be included for material evaluation. CoF and surface roughness should be implemented into wear evaluation. CLINICAL SIGNIFICANCE This study highlights the practical value of additively manufactured dental crown materials, particularly for provisional restorations. However, their extended use requires careful consideration of individual patient needs, emphasising the need for judicious clinical application evaluation.

Exploring the facilitators and barriers in opioid deprescribing for non-cancer pain treatment experienced by general practitioners: A qualitative study. Eur J Pain 2024; 28:1101-1115. [PMID: 38287911 DOI: 10.1002/ejp.2243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 01/09/2024] [Accepted: 01/15/2024] [Indexed: 01/31/2024]
Abstract
BACKGROUND Guidelines recommend opioid deprescribing in patients on long-term opioid treatment for chronic non-cancer pain. This study aims to explore facilitators and barriers in opioid deprescribing among general practitioners in the Netherlands. In addition, this study aims to identify possibilities for improvement regarding opioid deprescribing in primary care. METHODS Focus group discussions with Dutch General practitioners were held by two skilled moderators. The focus group discussions were transcribed verbatim and analysed using MAXQDA software. Three independent reviewers searched for overarching themes using thematic analysis with an inductive approach. Discussions were organized until data saturation was reached. RESULTS Twenty-two general practitioners participated in four focus group discussions. Five main themes emerged from the data: (1) patient-centred care; (2) ensuring proper pain management (3) dilemmas and hardships in dealing with opioid use disorder; (4) the competency gap; (5) needs and possibilities to improve opioid deprescribing in primary care. The first theme addresses the main facilitators in opioid tapering. The following three themes emerged as main barriers in opioid deprescribing. The fifth theme identified possibilities for change. CONCLUSIONS This study indicates the importance of intrinsic motivation and a tailored approach to deprescribe opioids in patients with chronic pain on long-term opioid treatment. Identified barriers include struggles in pain management, challenges caused by opioid use disorder, insufficient capacities such as time constraints and lack of skills. Recommendations for improvement involve enhanced collaboration with healthcare professionals in primary and secondary care, provision of practical tools and assurance of sufficient time. SIGNIFICANCE This focus group study among 22 Dutch general practitioners elucidates the complexities of opioid deprescribing and reveals pivotal themes such as patient-centred care, pain management challenges, and competency gaps. The findings underscore the crucial role of intrinsic motivation and that of a tailored approach in opioid deprescribing, while demonstrating how a lack in effective pain treatments, practical capacities and challenges caused by opioid dependence, impede opioid deprescribing. By uncovering these complexities, this study aims to inform future deprescribing strategies.

Abstract
AIM This study investigated the adjunctive effect of polydeoxyribonucleotide (PDRN) on bone formation in alveolar ridge preservation (ARP) sockets. MATERIALS AND METHODS Both mandibular second, third and fourth premolars of eight beagle dogs were randomly divided into ARP and ARP/PDRN groups. Following tooth extraction, ARP procedures were conducted using collagenized alloplastic graft material and bilayer collagen membrane soaked with normal saline (ARP group) or PDRN (ARP/PDRN group) for 10 min before application. Both groups were also randomly allocated to 2-, 4- or 12-week healing subgroups. The primary endpoint of this study was to compare histomorphometric differences between ARP and ARP/PDRN. The secondary endpoints of this study were to compare micro-CT analysis and three-dimensional volumetric measurement between the two groups. RESULTS In the histomorphometric analysis, the ARP/PDRN group exhibited greater new bone formation at coronal, middle and total position compared with the ARP group at 2-week healing. The number of newly formed blood vessels was higher in the ARP/PDRN group than in the ARP group at 2- and 4-week healing. In micro-CT analysis, the mean new bone volume/total bone volume between ARP and ARP/PDRN was statistically significant at 2-week healing. Ridge volume alterations were significantly decreased in the ARP/PDRN group during entire healing time compared with the ARP group, especially on the buccal side. CONCLUSIONS The application of PDRN in ARP might provide additional benefits for early bone regeneration and maintenance of buccal ridge volume.

Abstract
OBJECTIVE Oral status is an important indicator of past lifestyles. Determining the presence and extent of oral pathologies helps reconstruct average oral health, paramasticatory activities and diet of ancient and historical populations. DESIGN In this study, the dental remains from the early medieval cemetery of Früebergstrasse in Baar (Canton of Zug, Switzerland) and the high medieval Dalheim cemetery (North Rhine-Westphalia, Germany) were analyzed. Caries, periodontal condition, periapical lesions, antemortem tooth loss, and enamel hypoplasia were assessed in 654 teeth (993 observable loci) from 68 individuals (Baar: n = 36; Dalheim: n = 32). RESULTS The oral status of both populations was affected by age with higher values of tooth wear in advanced age individuals. High tooth wear values in both populations point towards the consumption of abrasive foods. Pronounced anterior tooth wear in Baar may also be due to non-masticatory tooth usage. Finally, possible nutritional deficiencies were hypothesized for the Baar population. A higher caries prevalence was observed in the Baar group, probably due to differences in carbohydrate intake. The oral conditions observed in the two studied populations exhibited several analogies, suggesting comparable lifestyles despite their separation in space and time. The only differences observed are related to the use of teeth as "tools" and are thus determined by behavioral choices rather than diverse socioeconomic factors. CONCLUSIONS Using multiple dental parameters to examine the oral health of premodern individuals can provide useful insights into the interactions between humans and their environment, from dietary patterns to paramasticatory activities.

Abstract
Molar-incisor hypomineralization (MIH) is a qualitative defect of dental enamel characterized by demarcated opacities present in permanent first molars and other teeth. It is considered a major clinical challenge in dentistry because it makes affected teeth more susceptible to fractures and dental caries. Its diagnosis is mainly clinical and there are few technological resources that allow for a more accurate diagnosis, especially with respect to the depth of the defect in the dental enamel. In this context, optical coherence tomography (OCT), which is routinely used in ophthalmology, can produce images of the depth of the dental enamel, making it a promising method. In this study, 33 teeth with different MIH severities were evaluated using OCT and microcomputed tomography (microCT). Semi-quantitative methods of grayscale pattern analysis were used to compare images obtained from different severities of MIH with the mineral density obtained through microCT. MicroCT evaluation revealed that hypomineralized enamel had a significantly lower mineral density than intact enamel. However, this difference was not observed between the mild and severe MIH lesions. In the OCT evaluation, significant differences were observed between the intact and hypomineralized enamel, and the gray value comparison provided a method for quantitative differentiation between the two. This study suggests that OCT could be a useful adjunct to traditional diagnostic methods for MIH, offering a noninvasive approach to evaluate enamel defects. RESEARCH HIGHLIGHTS: Combining optical coherence tomography with grayscale digital analysis shows potential as a promising method for diagnosing molar-incisor hypomineralization and assessing its level of severity.

Abstract
OBJECTIVES The addition of fluoride to community drinking water supplies has been a long-standing public health intervention to improve dental health. However, the evidence of cost-effectiveness in the UK currently lacks a contemporary focus, being limited to a period with higher incidence of caries. A water fluoridation scheme in West Cumbria, United Kingdom, provided a unique opportunity to study the contemporary impact of water fluoridation. This study evaluates the cost-effectiveness of water fluoridation over a 5-6 years follow-up period in two distinct cohorts: children exposed to water fluoridation in utero and those exposed from the age of 5. METHODS Cost-effectiveness was summarized employing incremental cost-effectiveness ratios (ICER, cost per quality adjusted life year (QALY) gained). Costs included those from the National Health Service (NHS) and local authority perspective, encompassing capital and running costs of water fluoridation, as well as NHS dental activity. The measure of health benefit was the QALY, with utility determined using the Child Health Utility 9-Dimension questionnaire. To account for uncertainty, estimates of net cost and outcomes were bootstrapped (10 000 bootstraps) to generate cost-effectiveness acceptability curves and sensitivity analysis performed with alternative specifications. RESULTS There were 306 participants in the birth cohort (189 and 117 in the non-fluoridated and fluoridated groups, respectively) and 271 in the older school cohort (159 and 112, respectively). In both cohorts, there was evidence of small gains in QALYs for the fluoridated group compared to the non-fluoridated group and reductions in NHS dental service cost that exceeded the cost of fluoridation. For both cohorts and across all sensitivity analyses, there were high probabilities (>62%) of water fluoridation being cost-effective with a willingness to pay threshold of £20 000 per QALY. CONCLUSIONS This analysis provides current economic evidence that water fluoridation is likely to be cost-effective. The findings contribute valuable contemporary evidence in support of the economic viability of water fluoridation scheme.

Abstract
OBJECTIVES After the shutdown of most dental services during the COVID-19 lockdown, the oral health community was concerned about an increase in prescribing opioids and antibiotics by dentists due to patients' limited access to dental offices. Therefore, the objective of this study was to investigate the impact of COVID-19 pandemic on the pattern of antibiotic and opioid prescriptions by dentists in Alberta, Canada. METHODS Data obtained from the Tracked Prescription Program were divided into antibiotics and opioids. Time periods were outlined as pre-, during-, and postlockdown (phase 1 and 2). For the number of prescriptions and average supply, each monthly average was compared to the corresponding prelockdown monthly average, using descriptive analysis. Time series analyses were conducted using regression analyses with an autoregressive error model. Data were trained and tested on monthly observations before lockdown and predicted for during- and postlockdown. RESULTS A total of 1.1 million antibiotics and 400,000 opioids dispense were tracked. Decreases in the number of prescriptions during lockdown presented for antibiotics (n = 24,933 vs. 18,884) and opioids (n = 8892 vs. 6051). Average supplies (days) for the antibiotics (n = 7.10 vs. 7.55) and opioids (n = 3.92 vs. 4.05) were higher during the lockdown period. In the trend analyses, the monthly number of antibiotic and opioid prescriptions showed the same pattern and decreased during lockdown. CONCLUSION The COVID-19 pandemic altered the trends of prescribing antibiotics and opioids by dentists. The full impact of COVID-19 pandemic on the population's oral health in light of changes in prescribing practices by dentists during and after lockdown warrants further investigation.

Abstract
OBJECTIVES This study was aimed to obtain an experimental bleaching agent by adding casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) in order to eliminate the mineral loss on the tooth surface after bleaching and to evaluate the bleaching effectiveness. MATERIALS AND METHODS In this study, experimental bleaching agents containing 1%, 3% CPP-ACP and without CPP-ACP were obtained. Bleaching effectiveness (color change), the effect of bleaching agents on mineral content (energy dispersive x-ray spectroscopy), surface morphology (scanning electron microscope), and surface hardness of enamel (Vicker's microhardness) before and after bleaching were evaluated. The obtained data were statistically analyzed. RESULTS When the bleaching levels of the groups were compared, no statistically significant difference was observed between the control and 1% CPP-ACP groups (p > 0.05) while the addition of 3% CPP-ACP decreased significantly the effectiveness of the bleaching agent (p < 0.05). When the effects of experimental bleaching agents on surface hardness were examined, while the enamel surface hardness decreased statistically significantly after application in the control group (p < 0.05), no statistically significant change was observed in surface hardness after the application of 1% CPP-ACP containing bleaching agent (p > 0.05). However, a statistically significant increase was observed in surface hardness after the application of 3% CPP-ACP containing bleaching agent (p < 0.05). When the Ca and P ratio of the groups were compared, no statistically significant difference was observed between the control and 1% CPP-ACP groups (p > 0.05), while they increased significantly in 3% CPP-ACP group (p < 0.05). CONCLUSIONS The addition of 1% CPP-ACP to the bleaching agent had positive effects on the mineral content and surface hardness of the enamel, and did not negatively affect the whitening effectiveness. CLINICAL SIGNIFICANCE Adding CPP-ACP to the bleaching agent at appropriate concentrations can eliminate possible negative effects without compromising the effectiveness of the bleaching agent.

EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2024; 28:779-788. [PMID: 38481021 DOI: 10.1111/eje.13005] [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: 03/23/2023] [Revised: 02/07/2024] [Accepted: 02/16/2024] [Indexed: 07/16/2024]
Abstract
INTRODUCTION Oral Health Therapists (OHTs) are a growing workforce globally, with skills in oral health prevention, treatment planning and management of disease. These professionals receive their training through a three-year undergraduate program which leads to the Bachelor of Oral Health degree in Australia and New Zealand. The aim of this study was to describe the learning environment for OHT students in Australia and New Zealand. OHT students were requested to complete the Dundee Ready Education Environment Measure (DREEM) to indicate their perceptions of the environment of their educational program. MATERIALS AND METHODS Bachelor of Oral Health students from 10 universities in Australia and New Zealand were invited to participate in the survey. The analysis of the students' experiences focused on five domains of educational environment: learning, teaching, academic self-perception, atmosphere and social self-perception. Total DREEM scores were compared to previously published literature for other health professions students. RESULTS A total of 336 OHT students completed the study, which represented 30% of all OHT students enrolled in the 10 participating universities. Using the DREEM, participants perception of the environment was more positive than negative with an average DREEM total score of 141 (70.5%) out of a maximum score of 200. The model demonstrates university region to be a major predictor in the overall DREEM score, with regional universities scoring higher than urban universities (p = .012). CONCLUSIONS The DREEM was used to describe OHT students perceptions of the learning environment in Australia and New Zealand. This study found that the university region is a significant predictor of positive experiences for OHT students. By identifying the strengths and weaknesses of contemporary Oral Health programs, this study offers insights into future improvements.

Abstract
OBJECTIVE This study aimed to investigate and explore Occupational Health and Safety (OHS) management, office ergonomics, and musculoskeletal symptoms in a group of office workers relocating from cell offices to activity-based flex offices (AFOs). METHODS The analysis was based on qualitative interview data with 77 employees and longitudinal questionnaire data from 152 employees. RESULTS Results indicate that there was a need to clarify roles and processes related to the management of OHS. Self-rated sit comfort, working posture, and availability of daylight deteriorated and symptoms in neck and shoulders increased after the relocation and seemed to be influenced by many factors, such as difficulties adjusting the workstations, the availability of suitable workplaces, and age, sex, and individual needs. CONCLUSION Research on the long-term effects of physical work environments and management of (OHS) issues after implementing activity-based flex offices is sparse. This study demonstrates the importance of planning and organising OHS issue management when implementing an AFO, and to carefully implement office ergonomics among office workers.

Perspectives of patients, dental professionals, and stakeholders on the use of silver diamine fluoride for the management of dental caries: A qualitative systematic review. J Dent 2024; 147:105145. [PMID: 38906452 DOI: 10.1016/j.jdent.2024.105145] [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: 03/11/2024] [Revised: 05/29/2024] [Accepted: 06/19/2024] [Indexed: 06/23/2024] Open
Abstract
OBJECTIVES This qualitative systematic review and meta-aggregation aimed to synthesise evidence regarding perceptions of patients, practitioners, and stakeholders on the use of Silver Diamine Fluoride (SDF) for the management of dental caries. DATA This review was reported in alignment with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and is registered with PROSPERO (CRD42023390301) and the Joanna Briggs Systematic Reviews register. SOURCES References were retrieved from PubMed, Web of Science, Scopus, and EMBASE using a pre-established search strategy. STUDY SELECTION Qualitative and mixed-methods studies examining perspectives of patients, practitioners, and/or stakeholders on the use of SDF were included. The initial search identified 650 articles eligible for inclusion, out of which 14 articles were included in the review. Reviewers synthesised findings and generated 11 distinct categories grouped into three synthesised findings: 1) Clinical use; 2) Staining; 3) Facilitators and barriers. CONCLUSIONS Practitioners and patients viewed SDF as a therapeutic option with multiple benefits. While aesthetic concerns may be a barrier to some groups, the acceptance of the treatment was influenced by other factors, such as trusting professional advice. CLINICAL SIGNIFICANCE Patient education is key for increased SDF acceptance. This systematic review can assist clinicians in addressing concerns regarding SDF therapy. Findings have the potential to inform policy decisions that address oral health inequities through patient-centred health care models.

[PMID: 38821394 DOI: 10.1016/j.jdent.2024.105105] [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: 05/21/2024] [Accepted: 05/28/2024] [Indexed: 06/02/2024] Open
Abstract
OBJECTIVES This study aimed to assess the reliability of AI-based system that assists the healthcare processes in the diagnosis of caries on intraoral radiographs. METHODS The proximal surfaces of the 323 selected teeth on the intraoral radiographs were evaluated by two independent observers using an AI-based (Diagnocat) system. The presence or absence of carious lesions was recorded during Phase 1. After 4 months, the AI-aided human observers evaluated the same radiographs (Phase 2), and the advanced convolutional neural network (CNN) reassessed the radiographic data (Phase 3). Subsequently, data reflecting human disagreements were excluded (Phase 4). For each phase, the Cohen and Fleiss kappa values, as well as the sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy of Diagnocat, were calculated. RESULTS During the four phases, the range of Cohen kappa values between the human observers and Diagnocat were κ=0.66-1, κ=0.58-0.7, and κ=0.49-0.7. The Fleiss kappa values were κ=0.57-0.8. The sensitivity, specificity and diagnostic accuracy values ranged between 0.51-0.76, 0.88-0.97 and 0.76-0.86, respectively. CONCLUSIONS The Diagnocat CNN supports the evaluation of intraoral radiographs for caries diagnosis, as determined by consensus between human and AI system observers. CLINICAL SIGNIFICANCE Our study may aid in the understanding of deep learning-based systems developed for dental imaging modalities for dentists and contribute to expanding the body of results in the field of AI-supported dental radiology..

Abstract
OBJECTIVE This study seeks to contribute to the current understanding of dietary variation in the late Prehistory of the northeastern Iberian Peninsula by examining buccal dental microwear patterns alongside archeological data from the same populations. MATERIALS AND METHODS Teeth from 84 adult individuals from eight distinct samples spanning the Middle-Late Neolithic to the Middle Bronze Age (Cova de l'Avi, Cova de Can Sadurní, Cova de la Guineu, Cova Foradada, Cova del Trader, Roc de les Orenetes, Cova del Gegant, Cova dels Galls Carboners) were analyzed using optical microscopy to examine buccal dental microwear patterns. RESULTS The analysis did not reveal clear chronological contrasts in the dietary habits of these samples. Nevertheless, significant differences emerged among the samples, leading to their classification into two distinct sets based on the abrasiveness of the diet informed by the microwear patterns. These findings offer similarities and differences among samples in the Iberian Peninsula, shedding light on the diverse lifestyles of these individuals. DISCUSSION Integrating our new results with other available proxies points to a multifaceted specialization in dietary patterns among these samples, influenced by factors such as habitat, resource selection, and available technology. By contextualizing the results within the broader context of the Iberian Peninsula, this research discerns shared characteristics and distinctive adaptations in the dietary practices and subsistence strategies of these groups. Ultimately, this study contributes to a deeper understanding of the intricate interplay between culture and environment in shaping human diets throughout late Prehistory.

Abstract
OBJECTIVE This scoping review aimed (1) to map, analyse, interpret and synthesize data from in situ studies on which substances were added to acidic beverages to reduce the erosive potential on tooth enamel and (2) to establish the level of evidence of the effectiveness of adding substances to acidic beverages to reduce the erosive potential on tooth enamel. DESIGN This is a scoping review, according to the methods from the Joanna Briggs Institute and PRISMA-ScR, with high-sensitivity searches in the databases PubMed (MEDLINE), Virtual Health Library, Embase (Elsevier), Scopus (Elsevier), Web of Science and ScienceDirect (Elsevier). In situ studies published in English until December 2022 were included. Studies that did not report a control group were excluded. To map and summarize the results, tables and figures were used. RESULTS From 895 potentially eligible articles, nine were included. Blackcurrant juices (n = 5) with the addition of calcium (n = 3) or xanthan gum (n = 2) formulations were the most tested in terms of reducing the erosive potential of the beverages on tooth enamel. The profilometer was the equipment of choice (n = 8) for evaluating the loss of enamel structure after the experimental tests. CONCLUSIONS Calcium and xanthan gum are among the most tested by in situ studies, offering promising results in reducing the erosive potential of fruit juices and carbonated and energy drinks.

Abstract
Sleep is a vital biological process that facilitates numerous vital functions integral to mental and physical restoration of the body. Sleep deprivation or poor sleep quality not only affects physical health but may also affect oral health. This scoping review aims to collate existing evidence related to the impact of sleep duration and/or quality on oral health. A systematic search strategy using PubMed, Embase, Scopus and CINAHL databases was performed to identify studies that assessed the association between sleep quality or duration and oral health or hygiene. Two researchers independently screened and extracted the data. Eligible studies were critically appraised using the NIH quality assessment tool for observational cohort and cross-sectional studies checklist. The search identified 18,398 studies, from which 14 fulfilled the inclusion criteria. Of the 14 papers, four papers were associated with effect of sleep on caries, 8 papers described the effect of sleep on gingival and periodontal health, and two papers described the effect of sleep on general oral health and oral disease symptoms. This review found a direct link between sleep and dental decay in children, and short sleep duration was associated with an increased risk of periodontitis adults.

Abstract
OBJECTIVES The objective was to assess the effectiveness of a Water Fluoridation program on a contemporary population of children. METHODS The study used a longitudinal prospective cohort design. In Cumbria, England, two groups of children were recruited and observed over a period of 5-6 years. The Birth Cohort consisted of families recruited from two hospitals in Cumbria where children were conceived after water fluoridation was reintroduced. The systemic and topical effects of community water fluoridation were evaluated in the Birth Cohort. The Older Cohort were approximately 5 years old and recruited from primary schools in Cumbria, shortly after water fluoridation was reintroduced. The predominantly topical effects of fluoridated water were evaluated in the Older Cohort. The primary outcome was the proportion of children with clinical evidence of caries experience in their primary (Birth Cohort) or permanent teeth (Older Cohort). Unadjusted and adjusted regression models were used for analysis. RESULTS The final clinical examinations for the Birth Cohort involved 1444 participants (mean age 4.8 years), where 17.4% of children in the intervention group were found to have caries experience, compared to 21.4% in the control group. A beneficial effect of water fluoridation was observed adjusting for deprivation (a socioeconomic measure), sex, and age, (adjusted odds ratio 0.74 95% CI 0.55 to 0.98). The final Older Cohort clinical examinations involved 1192 participants (mean age 10.8 years) where 19.1% of children in the intervention group were found to have caries experience compared to 21.9% in the control group (adjusted odds ratio 0.80, 95% CI 0.58 to 1.09). For both the Birth Cohort and Older Cohort there was evidence of a beneficial effect on dmft/DMFT count (IRR 0.61, 95% CI 0.44, 0.86) and (IRR 0.69, 95% CI 0.52, 0.93) respectively. No conclusive proof was found to indicate that the effectiveness of water fluoridation differed across area deprivation quintiles. CONCLUSIONS In the contemporary context of lower caries levels and widespread use of fluoride toothpaste, the impact of water fluoridation on the prevalence of caries was smaller than previous studies have reported. It is important to consider the clinical importance of the absolute reduction in caries prevalence against the use of other dental caries preventive measures.

Abstract
OBJECTIVES This study aimed to explore the dental staff knowledge of simulated patient methodology and support for its use to investigate dental staffs' triaging ability. MATERIAL AND METHODS Staff at dental practices in Western Australia were invited to participate in a cross-sectional online questionnaire, consisting of demographic questions, questions on triaging, and knowledge of simulated patient methodology. Descriptive and parametric tests were undertaken for quantitative data; qualitative responses were thematically analyzed. RESULTS Of the 100 participants, most were female (71%), aged 25-39 years (57%), dentists (46%), and worked in private practices (60%). While 82% of participants triaged dental appointment enquiries, only 26% had heard of simulated patient studies. The majority (66%) of participants spent 1-5 min when triaging appointments and less than half (29%) asked about medical history, aggravating or alleviating factors. Although there was a general positive attitude toward use of simulated patient methodology to investigate practice, some concerns were identified. CONCLUSIONS The findings of our exploratory study suggests that there may be a potential for utilizing simulated patient studies to improve the care of patients by dental receptionists in general dental practices.

Abstract
Dental restorative procedures remain a cornerstone of dental practice, and for many decades, dental amalgam was the most frequently employed material. However, its use is declining, mainly driven by its poor aesthetics and by the development of tooth-coloured adhesive materials. Furthermore, the Minamata Convention agreed on a phase-down on the use of dental amalgam. This concise review is based on a FDI Policy Statement which provides guidance on the selection of direct restorative materials as alternatives to amalgam. The Policy Statement was informed by current literature, identified mainly from PubMed and the internet. Ultimately, dental, oral, and patient factors should be considered when choosing the best material for each individual case. Dental factors include the dentition, tooth type, and cavity class and extension; oral aspects comprise caries risk profiles and related risk factors; and patient-related aspects include systemic risks/medical conditions such as allergies towards certain materials as well as compliance. Special protective measures (eg, a no-touch technique, blue light protection) are required when handling resin-based materials, and copious water spray is recommended when adjusting or removing restorative materials. Cost and reimbursement policies may need to be considered when amalgam alternatives are used, and the material recommendation requires the informed consent of the patient. There is no single material which can replace amalgam in all applications; different materials are needed for different situations. The policy statement recommends using a patient-centred rather than purely a material-centred approach. Further research is needed to improve overall material properties, the clinical performance, the impact on the environment, and cost-effectiveness of all alternative materials.

Moes E, Kuzawa CW, Edgar HJH. Sex-specific effects of environmental temperature during gestation on fluctuating asymmetry in deciduous teeth. AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY 2024; 184:e24944. [PMID: 38623790 DOI: 10.1002/ajpa.24944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 03/26/2024] [Accepted: 04/03/2024] [Indexed: 04/17/2024]
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.
