Abstract
As the opposite ends of the orodigestive tract, the oral cavity and the intestine share anatomical, microbial, and immunological ties that have bidirectional health implications. A growing body of evidence suggests an interconnection between oral pathologies and inflammatory bowel disease [IBD], implying a shift from the traditional concept of independent diseases to a complex, reciprocal cycle. This review outlines the evidence supporting an 'oral-gut' axis, marked by a higher prevalence of periodontitis and other oral conditions in IBD patients and vice versa. We present an in-depth examination of the interconnection between oral pathologies and IBD, highlighting the shared microbiological and immunological pathways, and proposing a 'multi-hit' hypothesis in the pathogenesis of periodontitis-mediated intestinal inflammation. Furthermore, the review underscores the critical need for a collaborative approach between dentists and gastroenterologists to provide holistic oral-systemic healthcare.

Abstract
This report aims to present a treatment of retrograde peri-implantitis originating from apical periodontitis of an adjacent tooth in an 84-year-old male. Apical periodontitis of the maxillary left central incisor (#9) extended to the apex of the maxillary left lateral incisor implant (#10), which had been functioning for 16 years. Root canal treatment for #9 was performed, followed by root end surgery to treat the apical periodontitis, which showed a periapical radiolucency measured 1 cm in its greatest dimension. After the root end filling was placed, neither bone substitute materials nor barrier membranes were used to fill and cover the bony defect area. A 2-year postoperative radiograph confirmed the osseous healing around the apices of #9 and #10.

Comparison of immediate vs. delayed guided tissue regeneration in Infrabony defect of second molars after adjacent third molar extraction: a retrospective study. BMC Oral Health 2024; 24:830. [PMID: 39044179 PMCID: PMC11265319 DOI: 10.1186/s12903-024-04591-1] [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: 03/04/2024] [Accepted: 07/08/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND The distal aspect of the second molar (d-M2) often exhibits infrabony defects due to the adjacent third molar. Although the defects can be treated by guided tissue regeneration (GTR) after removing the third molar, the optimal timing remains uncertain following third molar removal in clinical decision-making. This study aimed to compare delayed and immediate GTR treatments to assist in clinical decision-making. METHODS D-M2 infrabony defects with a minimum 1-year follow-up were collected and divided into three groups: Immediate GTR group, which underwent third molar extraction and received GTR simultaneously; Delayed GTR group, which underwent delayed GTR at least 3 months after third molar extraction; and Control group, which underwent only scaling and root planing during third molar extraction. The clinical and radiographic parameters related to the infrabony defect before GTR and post-surgery were evaluated using the Kruskal-Wallis test or one-way ANOVA, followed by post-hoc Dunn's test or the Bonferroni test for pairwise comparisons. RESULTS A total of 109 d-M2 infrabony defects were assessed. No significant differences were found between the two GTR groups, although both of them showed significant reductions in infrabony defect depth: the immediate GTR group (2.77 ± 1.97 mm vs. 0.68 ± 1.03 mm, p < 0.001) and the delayed GTR group (2.98 ± 1.08 mm vs. 0.68 ± 1.03 mm, p < 0.001) compared to the control group. CONCLUSION GTR can effectively improve d-M2 infrabony defects when the third molar is removed, whether simultaneously or delayed. Patients may experience less discomfort with immediate GTR treatment as it requires only one surgery.

Effect of mobile app-based oral hygiene instructions on clinical parameters, oral bacterial diversity, and composition of subgingival microbiota in periodontitis patients. J Oral Microbiol 2024; 16:2372206. [PMID: 38948658 PMCID: PMC11212576 DOI: 10.1080/20002297.2024.2372206] [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: 02/21/2024] [Accepted: 06/20/2024] [Indexed: 07/02/2024] Open
Abstract
Introduction Oral hygiene instruction (OHI) is essential during periodontitis treatment. Various OHI approaches have been explored, including mobile apps. Objective To evaluate the mobile app-based OHI's effect on periodontitis management by analyzing clinical parameters and subgingival microbiota. Methods Forty-four periodontitis patients were randomly assigned into two groups. The test group (n = 22) received scaling and root planing (SRP), OHI, and mobile app-based OHI, whereas the control group (n = 22) received SRP and OHI. Full mouth plaque score (FMPS), bleeding on probing (BOP) and probing pocket depth at the sampling sites (site-PPD) were assessed at baseline, one- and three-month visits. The 16S rRNA next-generation sequencing (NGS) was used to analyze subgingival plaque samples. Results Significant reduction in FMPS, BOP, and site-PPD at one- and three-month visits compared to baseline (p < 0.001) with no significant differences across groups (p > 0.05). In test groups, intra-group analysis showed better improvement in BOP and site-PPD (p < 0.05) than control. The diversity and composition of subgingival microbiota did not differ between groups or timepoints (p > 0.05). Conclusions Mobile app-based OHI showed no superior effects on improving clinical parameters and subgingival microbiota compared to conventional OHI. Further investigation into its long-term impact on periodontitis treatment is needed.

[PMID: 38920871 PMCID: PMC11202695 DOI: 10.3390/dj12060170] [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: 04/23/2024] [Revised: 05/23/2024] [Accepted: 05/31/2024] [Indexed: 06/27/2024] Open
Abstract
Teeth with attachment loss involving the root apex are severely compromised and have a poor periodontal prognosis. In cases where periodontal regeneration is possible, current guidelines suggest that endodontic treatment is performed first. However, root canal treatment increases the overall treatment time and costs, has risks of endodontic complications, and could predispose teeth to mechanical failure. In this case report, two patients diagnosed with periodontitis stage III/IV grade C, no history of smoking or diabetes, and attachment loss involving the root apex of a tooth, were treated with guided tissue regeneration. These two cases are unique because successful periodontal regeneration was carried out without endodontic treatment, and the vitality of these teeth was maintained longitudinally. This report presents the management that led to this clinical outcome, and important guidelines for case selection are identified. Within the limitations of this study, vital teeth with radiographic bone loss involving the apex may be treated successfully with periodontal regeneration and remain vital at least in the short- to medium-term.

Abstract
This study reviews and appraises the methodological and reporting quality of prediction models for tooth loss in periodontitis patients, including the use of regression and machine learning models. Studies involving prediction modeling for tooth loss in periodontitis patients were screened. A search was performed in MEDLINE via PubMed, Embase, and CENTRAL up to 12 February 2022, with citation chasing. Studies exploring model development or external validation studies for models assessing tooth loss in periodontitis patients for clinical use at any time point, with all prediction horizons in English, were considered. Studies were excluded if models were not developed for use in periodontitis patients, were not developed or validated on any data set, predicted outcomes other than tooth loss, or were prognostic factor studies. The CHARMS checklist was used for data extraction, TRIPOD to assess reporting quality, and PROBAST to assess the risk of bias. In total, 4,661 records were screened, and 45 studies were included. Only 26 studies reported any kind of performance measure. The median C-statistic reported was 0.671 (range, 0.57-0.97). All studies were at a high risk of bias due to inappropriate handling of missing data (96%), inappropriate evaluation of model performance (92%), and lack of accounting for model overfitting in evaluating model performance (68%). Many models predicting tooth loss in periodontitis are available, but studies evaluating these models are at a high risk of bias. Model performance measures are likely to be overly optimistic and might not be replicated in clinical use. While this review is unable to recommend any model for clinical practice, it has collated the existing models and their model performance at external validation and their associated sample sizes, which would be helpful to identify promising models for future external validation studies.

Abstract
OBJECTIVE The aim of this study was to detect and compare the tissular expression of neutrophil extracellular traps (NETs) in peri-implant and periodontal samples of patients with peri-implantitis, periodontitis, and controls. MATERIALS AND METHODS An observational study was performed on patients with peri-implantitis, periodontitis, and controls. Peri-implant and/or periodontal clinical examinations were performed on each participant. Tissue samples were collected during tooth/implant extraction for clinical reasons. Electron microscopy analysis, Picro-Sirius red staining, immunohistochemical (CD15), and immunofluorescence (citrullinated H3 and myeloperoxidase) techniques were performed to detect NET-related structures and the degree of connective tissue destruction, between the study groups. RESULTS Sixty-four patients were included in the study: 28 peri-implantitis, 26 periodontitis, and 10 controls, with a total of 51 implants, 26 periodontal teeth, and 10 control teeth. Neutrophil release of nuclear content was observed in transmission electron microscopy. Immunohistochemical analysis showed a greater CD15 expression in both peri-implantitis and periodontitis compared to controls (p < 0.001), and peri-implantitis presented lower levels of connective tissue and collagen compared to both periodontitis (p = 0.044; p < 0.001) and controls (p < 0.001). Immunofluorescence showed greater citH3 expression in peri-implantitis than the one found in both periodontitis (p = 0.003) and controls (p = 0.048). CONCLUSIONS A greater presence and involvement of neutrophils, as well as a greater connective tissue destruction were observed in cases of peri-implantitis. A higher expression of NET-related markers was found in mucosal samples of peri-implantitis compared to periodontitis and controls.

Abstract
Cemental tears are often misdiagnosed due to their scarcity. In this study, we reported the second largest cohort of cemental tears thus far. By reviewing the radiographic data and medical records of 63 cemental tear teeth, we found that periapical periodontitis was the most frequent diagnosis, followed by cracked tooth/root fracture and periodontitis. Most of the cemental tear teeth that did not have root canal treatment had vital pulp. The apical third of the root was the most prominent site of cemental tears. Cemental tears occurred more frequently in the palatal root of the maxillary molars and in the mesial root of the two-root mandibular molars. Uncontrollable bone loss and tooth mobility were the two main reasons for the extraction of teeth with cemental tears. We suggest that cemental tears should be included in the differential diagnosis of periapical periodontitis, cracked tooth, vertical root fracture and periodontitis, especially for teeth with periapical radiolucency and vital pulp. We believe our study could provide more insights into cemental tears, which will aid clinicians in the early diagnosis and proper treatment of cemental tears.

Abstract
BACKGROUND The aim of this retrospective study was to investigate the risk of tooth loss for teeth adjacent and nonadjacent to dental implants. METHODS A total of 787 patients with an average follow-up of 57.1 months were examined to define the tooth loss, cumulative survival rate, and odds ratio (OR) for teeth adjacent versus nonadjacent to implants. A multivariate logistic regression was employed to assess the association between dental history and various recorded etiologies of tooth loss among teeth adjacent to implants. RESULTS The incidence of tooth loss for teeth adjacent to implants was 8.1% at the tooth level and 15.1% at the patient level, while 0.7% and 9.5% at the tooth and patientlevel for teeth nonadjacent to implants. The 10-year cumulative survival rate for teeth adjacent to implants was 89.2%, and the primary etiology of tooth loss was root fracture (45.2%). The risk of tooth loss among teeth adjacent versus nonadjacent to implants was significantly higher (OR 13.15). Among teeth adjacent to implants, root canal-treated teeth had a significantly higher risk of tooth loss due to root fracture (OR 7.72), a history of existing restoration significantly increased the risk of tooth loss due to caries (OR 3.05), and a history of periodontitis significantly increased the risk of tooth loss due to periodontitis (OR 38.24). CONCLUSION The present study demonstrated that after patients received dental implant treatment, teeth adjacent to implants showed a 13.2-fold higher risk of tooth loss compared to teeth nonadjacent to implants, with the primary etiology being root fracture.

Abstract
AIMS To evaluate osteoradionecrosis (ORN) incidence in a cohort of patients undergoing tooth extraction (TE) before radiotherapy (RT) for head and neck cancers. METHODS The study protocol was approved by the Ethics Committee of Università Cattolica del Sacro Cuore (ID-2132) and registered at clinicaltrials.gov (ID: NCT04009161). TE was performed in case of signs of pericoronitis, periapical lesions, restorative impossibility, severe periodontitis. ORN was defined as exposed bone at an unhealed post-extraction socket in the absence of oncological recurrence. The RT plans were reviewed, and each post-extractive socket was contoured to calculate the received radiation dose. RESULTS In total, 156 patients with 610 TE were enrolled. The mean follow-up was 567 days. ORN was diagnosed in four patients (2.6% of patients and 0.7% of TE). Need for osteotomy and radiation dose at the extraction site were associated with ORN (OR for osteotomy: 21.9, 95% CI: 2.17-222.2, p = 0.009; OR for RT dose: 1.1, 95% CI: 1-1.15, p = 0.05). CONCLUSIONS TE appears to be a significant risk factor for ORN, particularly when osteotomy is required, and post-extraction sockets receive a high RT dosage. This study proposes a decision-making algorithm for TE and outlines a straightforward surgical protocol.

J Periodontol 2024; 95:9-16. [PMID: 37287337 DOI: 10.1002/jper.23-0198] [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: 03/21/2023] [Revised: 05/11/2023] [Accepted: 05/28/2023] [Indexed: 06/09/2023]
Abstract
BACKGROUND The purpose of this randomized, controlled split-mouth study was to evaluate a videoscope as a visual adjunct to scaling and root planing when utilized in combination with minimally invasive surgery. METHODS Twenty-five pairs (89 interproximal surfaces) of periodontally hopeless teeth planned for extraction were scaled and root planed with minimal surgical access using surgical loupes (control) or adjunctive use of a videoscope (test). Teeth were extracted with minimal trauma, stained with methylene blue, and photographed with a digital microscope for analysis. The primary outcome of residual calculus was calculated as a percentage of the total interproximal area of interest. Secondary outcomes included treatment time, as well as residual calculus according to probing depth, tooth location, and treatment date. Data were analyzed using Student's paired t-tests, two-way analyses of variance, and Spearman's correlation tests. RESULTS Residual calculus area was 2.61% on control and 2.71% on test surfaces with no significant difference between groups. Subgroup analysis showed no difference in residual calculus between groups at moderate or deep sites. Treatment time per surface was significantly longer in the test group compared to the control group. Treatment order, tooth location, and operator experience did not significantly affect the primary outcome. CONCLUSIONS Though the videoscope provided excellent visual access, it did not improve the efficacy of root planing for flat interproximal surfaces during minimally invasive periodontal surgery. Small amounts of calculus remain after instrumentation even with minimal surgical access and when root surfaces appear visually clean and tactilely smooth.

Abstract
BACKGROUND Pathological root resorption affects permanent teeth and is usually triggered by infectious-inflammatory stimuli and/or dental trauma. Periodontitis and traumatic occlusion have been reported as possible causative factors of root resorptions, whilst the impact of systemic diseases is less well understood. This case highlights the need for consideration of multiple risk factors, especially when presenting in combination. METHODS AND RESULTS A 62-year-old South Asian female presented with unstable Stage IV Grade C periodontitis, poor oral hygiene and multiple autoimmune conditions including oral lichen planus. Clinical and radiographic examination revealed multiple advanced apical and external root resorptions of the patient's molars associated with periapical bone loss, despite of a minimally restored dental status. CONCLUSION A likely etiology of this patient's multiple root resorptions is the presence of unstable periodontitis with periodontal-endodontic lesions, exacerbated by a dysbalanced immune response to infectious agents. Appropriate monitoring and managing of such patients can prevent or limit the pathological process of inflammatory root resorption. KEY POINTS Why is this case new information? This is the first report documenting advanced multiple external inflammatory root resorptions in a periodontitis patient with oral and systemic co-morbidities. What are the keys to successful management of this case? Early diagnosis, prevention and intervention to limit periodontal inflammation, endodontic infection and occlusal trauma. What are the primary limitations to success in this case? Late diagnosis of multiple root resorptions, palliative periodontal treatment due to poor oral hygiene compliance, and poorly controlled systemic inflammation favoring the persistence of a dysregulated immune response to the oral microbiota.

Abstract
BACKGROUND This study aimed to identify predictors associated with tooth loss in a large periodontitis patient cohort in the university setting using the machine learning approach. METHODS Information on periodontitis patients and 18 factors identified at the initial visit was extracted from electronic health records. A two-step machine learning pipeline was proposed to develop the tooth loss prediction model. The primary outcome is tooth loss count. The prediction model was built on significant factors (single or combination) selected by the RuleFit algorithm, and these factors were further adopted by the count regression model. Model performance was evaluated by root-mean-squared error (RMSE). Associations between predictors and tooth loss were also assessed by a classical statistical approach to validate the performance of the machine learning model. RESULTS In total, 7840 patients were included. The machine learning model predicting tooth loss count achieved RMSE of 2.71. Age, smoking, frequency of brushing, frequency of flossing, periodontal diagnosis, bleeding on probing percentage, number of missing teeth at baseline, and tooth mobility were associated with tooth loss in both machine learning and classical statistical models. CONCLUSION The two-step machine learning pipeline is feasible to predict tooth loss in periodontitis patients. Compared to classical statistical methods, this rule-based machine learning approach improves model explainability. However, the model's generalizability needs to be further validated by external datasets.

Abstract
Tooth autotransplantation is a versatile procedure with several clinical applications among patients across different age groups. The success of this procedure depends on multiple factors. Despite the wealth of studies available, no single primary study or systematic review is able to report on every factor affecting the outcomes of autotransplantation. The aims of this umbrella review were to evaluate treatment-related and patient-related outcomes of autotransplantation and to assess the pre-, peri- or post-operative factors that could affect these. An umbrella review was conducted according to the PRISMA statement. A literature search of five databases was performed up to 25 September 2022. Systematic Reviews (SR) with and without meta-analysis evaluating autotransplantation were included. Calibration among reviewers was carried out prior to study selection, data extraction and Risk of Bias (RoB) assessment. Study overlap was calculated using corrected covered area. Meta-meta-analysis (MMA) was performed for suitable SRs. The AMSTAR 2 critical appraisal tool was used to evaluate the quality of evidence. Seventeen SRs met the inclusion criteria. Only two SRs were suitable for conduct of MMA on autotransplantation of open apex teeth. The 5-year and 10-year survival rates were >95%. A narrative summary on factors that could affect autotransplantation outcomes and comparisons of autotransplantation to other treatment options were reported. Five SRs were rated as 'low quality' and 12 SRs were rated as 'critically low quality' in the AMSTAR 2 RoB assessment. In order to facilitate a more homogenous pool of data for subsequent meta-analysis, an Autotransplantation Outcome Index was also proposed to standardise the definition of outcomes. Autotransplantation of teeth with open apices have a high survival rate. Future studies should standardise the reporting of clinical and radiographic findings, as well as the definition of outcomes.

Abstract
Background, recently, amnion-chorion membranes (ACMs), has provided new strategy to induce tissue regeneration in periodontal disorders. These biomaterials are rich sources of various biomarkers such as growth factors, proteins, and stem cells (SCs) which can accelerate regeneration. Numerous studies have been investigated beneficial effects of these materials on periodontal disorders⁹ tissue regeneration. Objective, the aim of this review was to evaluate therapeutic efficacy of these biomaterials, (combination of different effective biomarkers and SCs), more cost-effectiveness and with lower immune adverse effects on tissue regenerating in periodontal diseases. Methods, inclusion criterion was the English language and full text publications. Reviews, or strategies other than ACMs application for periodontal disorders treatment, and mechanism other than tissue regeneration were excluded. Data source, this search was done in PubMed, web of science (WOS) and Scopus using keywords. The search were repeated in May 2023 to identify any report that emerged during the time to develop the manuscript. After assessing bias, total of 151 articles were initially identified. After deleting duplication (30) using hand- screening, 121 papers met all inclusion criteria and were selected. Moreover, 31 papers were reviewed and excluded. Among remained articles (90), 57 articles excluded due to unrelated, 33 articles were assessed for the efficacy of ACMs on treating periodontal disorders. The most of studies used this material in the coronally flap technique. Miller recession defects was the most investigated periodontal disorder and clinical parameters were the most evaluated parameters in assessing the efficacy of ACMs. Discussion, different findings might be explained by different study designs, application techniques, or periodontal disorders in these studies. In the present review, we summarize the impacts of ACMs on tissues regeneration in treating periodontal disorders, but despite the promising and ameliorating results of this review, further studies are needed to assess these beneficial effects tissue to clarify the their helpfulness in clinical management of periodontal disorders. This review did not receive any funding.

Abstract
BACKGROUND Affected tooth conservation is an often-overlooked problem in odontogenic sinusitis (ODS) treatment. Treatable dental conditions are improperly managed with extractions imposing an unnecessary health burden on patients. Furthermore, no down-to-earth protocols have been proposed for the clinical management of these patients. AIM This study aims to prospectively validate a treatment protocol for ODS based on dental mobility, an indirect sign of poor long-term tooth survival. The protocol suggests endoscopic sinus surgery (ESS) alone followed by dental treatment for immobile affected teeth, and concomitant ESS and extraction for mobile teeth. Extraction of immobile teeth is considered if inflammation persists after the treatment. MATERIAL AND METHODS Forty cases treated with our protocol were prospectively examined about ODS cure and preservation of affected teeth. RESULTS Among the 35 patients with immobile affected teeth, only one required extraction for complete ODS cure after ESS. All five cases with mobile teeth and one with postoperative extraction had marginal periodontitis. CONCLUSION AND SIGNIFICANCE Ninety-seven percent of immobile affected teeth were preserved with complete ODS cure in this study. In case marginal periodontitis is present, extraction is likely to be necessary, although ESS should be prioritized over blanket extractions to preserve the teeth for patients' quality life.

Abstract
To retrospectively analyze local and systemic factors that resulted in the short-term tooth loss of teeth that were previously assigned a favorable prognosis in patients who were seen and treated over an observational five-year period. This retrospective study included the records of patients who had a minimum of two dental exams at least twelve months apart over a 5-year period. This study investigated extracted teeth with an initially favorable periodontal prognosis that were then divided into one of four categories based on the reason for extraction: caries, periodontal disease, endodontic reasons, or fracture. Patient- and tooth-related factors associated with the extracted teeth were recorded: crown-to-root ratio, initial pocket depth, initial periodontal diagnosis, maintenance interval, presence of existing restoration, furcation involvement, and systemic conditions. Data analysis was performed using a linear mixed model. A total of 50 patients with 111 teeth met the inclusion criteria for this study. A higher odds ratio (OR) for tooth loss due to caries, endodontic reasons, and fracture were found in teeth with a history of root canal treatment with an OR of 3.61, 3.86, and 2.52, respectively. For tooth loss due to periodontal disease, higher ORs were found in patients who were on anti-depressants (OR = 4.28) and patients who had an initial diagnosis of Stage III/IV periodontitis (OR = 2.66). In addition, teeth with initial probing depths ≥5 mm (OR = 4.32) and with furcation involvement (OR = 1.93) showed a higher OR for tooth loss due to periodontal disease. Within the limitations of this study, previously root-canal-treated teeth present a higher OR for early loss due to caries, recurrent endodontic lesions, or fracture. In addition, patients with anti-depressant medication use, sporadic maintenance, initial probing depths ≥5 mm, and furcation involvement represent a significantly higher OR of tooth loss due to periodontal disease even for initially favorable teeth.

Machine Learning in Predicting Tooth Loss: A Systematic Review and Risk of Bias Assessment. J Pers Med 2022; 12:jpm12101682.

Abstract
Predicting tooth loss is a persistent clinical challenge in the 21st century. While an emerging field in dentistry, computational solutions that employ machine learning are promising for enhancing clinical outcomes, including the chairside prognostication of tooth loss. We aimed to evaluate the risk of bias in prognostic prediction models of tooth loss that use machine learning. To do this, literature was searched in two electronic databases (MEDLINE via PubMed; Google Scholar) for studies that reported the accuracy or area under the curve (AUC) of prediction models. AUC measures the entire two-dimensional area underneath the entire receiver operating characteristic (ROC) curves. AUC provides an aggregate measure of performance across all possible classification thresholds. Although both development and validation were included in this review, studies that did not assess the accuracy or validation of boosting models (AdaBoosting, Gradient-boosting decision tree, XGBoost, LightGBM, CatBoost) were excluded. Five studies met criteria for inclusion and revealed high accuracy; however, models displayed a high risk of bias. Importantly, patient-level assessments combined with socioeconomic predictors performed better than clinical predictors alone. While there are current limitations, machine-learning-assisted models for tooth loss may enhance prognostication accuracy in combination with clinical and patient metadata in the future.

Abstract
PURPOSE The aim of this systematic review was to identify studies with a minimum of 5-years follow-up, reporting on the management of periodontally compromised teeth with either extraction and subsequent implant placement or teeth preservation with conventional periodontal treatment and application of regenerative procedures. The outcomes of these two approaches, based on clinical and radiographic data and the incidence of tooth- and implant-loss, were also investigated. MATERIAL AND METHODS A systematic search for studies reporting on clinical and radiographic outcomes of periodontal treatment or replacement of periodontally compromised teeth with implants was conducted in 3 electronic databases, followed by a hand-search in 8 journals. Only randomized controlled trials (RCTs), cohort studies, and case series with prospective design were included. RESULTS The initial search resulted in 1080 papers. After the first two screenings, 24 publications were selected for inclusion in this systematic review. The treatment protocols for the teeth preservation group contained nonsurgical and/or surgical periodontal treatment with or without regeneration procedures. The implant studies included extraction of periodontally involved teeth and implant placement with or without bone and soft tissue augmentation, followed by restoration with fixed dental prostheses (FDPs). Survival rates ranged between 81.8% and 100% in the tooth retention group, and between 94.8% and 100% in the implant group. In the extraction group, no complications were reported for 76.09% of the implants. Similarly, no complications were reported for 86.83% of the tooth retention group. The lack of standardized comparable studies prohibited conduction of a metaanalysis. CONCLUSION Both treatment approaches, treatment of periodontally compromised teeth, or tooth extraction followed by implant placement, present high survival rates. The application of bone regeneration techniques improves the long-term prognosis of periodontally involved teeth. Hence, treatment of periodontally involved teeth with subsequent application of a rigorous maintenance protocol can be a viable alternative for a number of years, before proceeding to extraction and replacement with dental implants. More well-designed randomized controlled trials are needed in order to draw definite conclusions on the subject.

Abstract
Multiple systems and associated factors have been described in the literature to assess the prognosis of teeth with periodontal disease. Nowadays there is a tendency among clinicians to consider implants as the best solution after tooth extraction, in cases of teeth with a questionable prognosis. However, the value of the natural tooth must be considered, as the proprioception of the periodontal ligament is preserved, and it adapts to stress during functional loads. We first review the literature focusing on analyzing the factors that should guide decision-making to maintain or extract a tooth with a compromised periodontium. Then, we propose a schematic diagram of prognostic indicators to reflect the main factors to consider and the survival rate that each one represents when preserving or extracting a tooth.

A survey questionnaire containing two cases (Case A; periodontal abscess and Case B; periapical abscess) with four questions per case was delivered to potential participants. Fifty-nine DPs voluntarily participated in the survey. For senior students, the case study was a part of their course requirements; one of the two cases (either Case A or B) was randomly assigned to the 126 seniors. The distribution of responses was significantly different between the DP and senior groups except for the diagnosis of Case B (Fisher’s exact test; p = 0.05). Only 31% of the participants diagnosed Case A as periodontal abscess; most of them selected periodontal surgery as the first treatment option. Despite a high agreement in diagnosing Case B, the choice of treatment was significantly different; the most frequent treatment option was extraction (51%) from the DP group and root canal retreatment (57%) from the senior group. The study revealed that the diagnosis of periodontal abscess was more challenging than that of periapical abscess among dental professionals.

J Clin Periodontol 2022; 49:740-748. [PMID: 35702014 PMCID: PMC9543611 DOI: 10.1111/jcpe.13672] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 05/11/2022] [Accepted: 05/18/2022] [Indexed: 12/14/2022]
Abstract
Aim The aim of this analysis was to assess how different tooth‐prognosis systems could predict tooth loss in a cohort of periodontitis patients followed up prospectively during supportive periodontal care (SPC). Materials and Methods Clinical and radiographic data of 97 patients undergoing regular SPC for 5 years were used to assign tooth prognosis using four different systems (McGuire & Nunn, 1996; Kwok & Caton, 2007; Graetz et al., 2011; Nibali et al., 2017). Three independent examiners assigned tooth prognosis using all four systems, following a calibration exercise. The association between prognostic categories and tooth loss was tested for each prognostic system separately and across prognostic systems. Results All four systems showed good reproducibility and could identify teeth at higher risk of being lost during 5 years of SPC; the risk of tooth loss increased with the worsening of tooth‐prognosis category (p < .0001). Although specificity and negative predictive values were good, low sensitivity and positive predictive values were detected for all systems. Conclusions Previously published periodontal prognostic systems exhibited good reproducibility and predictive ability for tooth retention. However, low sensitivity was detected, with several teeth in the worst prognosis category being retained at 5 years. Some modifications in the number of categories and their definitions are suggested.

Abstract
The accurate diagnosis of individual tooth prognosis has to be determined comprehensively in consideration of the broader treatment plan. The objective of this study was to establish an effective artificial intelligence (AI)-based module for an accurate tooth prognosis decision based on the Harvard School of Dental Medicine (HSDM) comprehensive treatment planning curriculum (CTPC). The tooth prognosis of 2359 teeth from 94 cases was evaluated with 1 to 5 levels (1—Hopeless, 5—Good condition for long term) by two groups (Model-A with 16, and Model-B with 13 examiners) based on 17 clinical determining factors selected from the HSDM-CTPC. Three AI machine-learning methods including gradient boosting classifier, decision tree classifier, and random forest classifier were used to create an algorithm. These three methods were evaluated against the gold standard data determined by consensus of three experienced prosthodontists, and their accuracy was analyzed. The decision tree classifier indicated the highest accuracy at 0.8413 (Model-A) and 0.7523 (Model-B). Accuracy with the gradient boosting classifier and the random forest classifier was 0.6896, 0.6687, and 0.8413, 0.7523, respectively. Overall, the decision tree classifier had the best accuracy among the three methods. The study contributes to the implementation of AI in the decision-making process of tooth prognosis in consideration of the treatment plan.

Abstract
BACKGROUND The recently published clinical practice guideline (CPG) for the treatment of periodontitis in stages I-III provided evidence-based recommendations for the treatment of periodontitis patients, defined according to the 2018 classification. Stage IV periodontitis shares the severity and complexity characteristics of stage III periodontitis, but includes the anatomical and functional sequelae of tooth and periodontal attachment loss (tooth flaring and drifting, bite collapse, etc.), which require additional interventions following completion of active periodontal therapy. AIM To develop an S3 Level CPG for the treatment of stage IV periodontitis, focusing on the implementation of inter-disciplinary treatment approaches required to treat/rehabilitate patients following associated sequelae and tooth loss. MATERIALS AND METHODS This S3 Level CPG was developed by the European Federation of Periodontology (EFP), following methodological guidance from the Association of Scientific Medical Societies in Germany and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process. A rigorous and transparent process included synthesis of relevant research in 13 specifically commissioned systematic reviews, evaluation of the quality and strength of evidence, the formulation of specific recommendations and a structured consensus process with leading experts and a broad base of stakeholders. RESULTS The S3 Level CPG for the treatment of stage IV periodontitis culminated in recommendations for different interventions, including orthodontic tooth movement, tooth splinting, occlusal adjustment, tooth- or implant-supported fixed or removable dental prostheses and supportive periodontal care. Prior to treatment planning, it is critically important to undertake a definitive and comprehensive diagnosis and case evaluation, obtain relevant patient information, and engage in frequent re-evaluations during and after treatment. The periodontal component of therapy should follow the CPG for the treatment of periodontitis in stages I-III. CONCLUSIONS The present S3 Level CPG informs clinical practice, health systems, policymakers and, indirectly, the public on the available and most effective modalities to treat patients with stage IV periodontitis and to maintain a healthy dentition over lifetime, according to the available evidence at the time of publication.

Abstract
Smoking is considered as the major environmental risk factor for periodontal diseases. Smokers have a higher risk for severe periodontitis with more periodontal tissue destruction, more gingival recession, and more susceptibility for tooth loss. The aim of this narrative review is to provide up-to-date evidence on the clinical outcomes of periodontal treatment in smokers. Electronic databases were searched for studies that compare the clinical outcomes in smokers and non-smokers following non-surgical and surgical periodontal treatment modalities and also during the supportive periodontal treatment. Clinical studies published before May 2021 were included in the review. Smokers have a higher risk for recurrence of periodontal disease and the response to non-surgical as well as surgical periodontal treatment is not as good as that of non-smokers. Moreover, there is a dose-response effect in the adverse effects of smoking on periodontal health. Compared to non-smokers, smoker patients with periodontitis tend to respond less favorably to non-surgical and surgical periodontal treatment, and exhibit recurrence more frequently during supportive periodontal treatment. Along with the periodontal treatment, smokers may be encouraged to quit. Long follow-up and the communication between the dentist and the patient give a great opportunity for such counseling.

Abstract
AIM Tooth-level prognostic systems can be used for treatment planning and risk assessment. This retrospective longitudinal study aimed to evaluate the prognostic performance of 10 different tooth-level risk assessment systems in terms of their ability to predict periodontal-related tooth loss (TLP). MATERIALS AND METHODS Data were retrieved retrospectively from patients who received surgical and non-surgical periodontal treatment. Data on medical history and smoking status at baseline and the last maintenance visit were collected. Ten tooth-level prognostic systems were compared using both univariate and multivariate Cox proportional hazard regression models to analyse the prognostic capability of each system for predicting TLP risk. RESULTS One-hundred and forty-eight patients with 3787 teeth, followed-up for a mean period of 26.5 ± 7.4 years, were evaluated according to 10 different tooth-level prognostic systems, making up a total of 37,870 individual measurements. All compared prognostic systems were able to stratify the risk of TLP at baseline when different classes of association were compared. After controlling for maintenance, age, and gender, all systems exhibited excellent predictive capacity for TLP with no system scoring a Harrell's C-index less than 0.925. CONCLUSIONS All tooth-level prognostic systems displayed excellent predictive capability for TLP. Overall, the Miller and McEntire system may have shown the best discrimination and model fit, followed by the Nunn et al. system.

Abstract
BACKGROUND This retrospective study assessed the effect of non-surgical and surgical mechanical therapy for furcation-involved molars. METHODS Furcation defects treated and followed for at least 1 year were selected. Data relative to the clinical outcomes were recorded. The immediate (3- to 6-month) clinical outcomes and the long-term survival of the treated molars were assessed. The potential variables influencing the treatment outcomes through multi-level regression analysis, and Cox Proportional-Hazards Models were also analyzed. RESULTS One hundred and eighty-four molars were included with an average follow-up of 7.52 years. At the 3- to 6-month re-evaluation 1.39 ± 0.99 mm pocket depth reduction, 0.88 ± 1.29 mm clinical attachment gain, and a 0.51 ± 1.13 mm increase in recession was observed. The 5- and 10-year survival rates were 88.3% and 61.3%, respectively. The horizontal and vertical extent of furcation involvement, baseline probing depth, mucoperiosteal flap elevation, and the frequency of supportive periodontal therapy influenced the clinical outcomes and tooth survival. CONCLUSION Non-surgical and surgical mechanical root debridement is a viable treatment for the management of furcation involved molars with shallow horizontal and vertical components.

Abstract
Objectives The aim of this study was to develop a prognostic tool to estimate long-term tooth retention in periodontitis patients at the beginning of active periodontal therapy (APT). Material and methods Tooth-related factors (type, location, bone loss (BL), infrabony defects, furcation involvement (FI), abutment status), and patient-related factors (age, gender, smoking, diabetes, plaque control record) were investigated in patients who had completed APT 10 years before. Descriptive analysis was performed, and a generalized linear-mixed model-tree was used to identify predictors for the main outcome variable tooth loss. To evaluate goodness-of-fit, the area under the curve (AUC) was calculated using cross-validation. A bootstrap approach was used to robustly identify risk factors while avoiding overfitting. Results Only a small percentage of teeth was lost during 10 years of supportive periodontal therapy (SPT; 0.15/year/patient). The risk factors abutment function, diabetes, and the risk indicator BL, FI, and age (≤ 61 vs. > 61) were identified to predict tooth loss. The prediction model reached an AUC of 0.77. Conclusion This quantitative prognostic model supports data-driven decision-making while establishing a treatment plan in periodontitis patients. In light of this, the presented prognostic tool may be of supporting value. Clinical relevance In daily clinical practice, a quantitative prognostic tool may support dentists with data-based decision-making. However, it should be stressed that treatment planning is strongly associated with the patient’s wishes and adherence. The tool described here may support establishment of an individual treatment plan for periodontally compromised patients.

Abstract
Background: Dental pulp tissue within the central cavity of the tooth is composed of dental pulp stem cells (DPSC). These mesenchymal stem cells have good proliferative as well as differentiation potential. DPSC has been isolated even from teeth with inflamed pulps and is found to retain their proliferative and differentiation potential. Little research is available about the viability and differentiation potential of DPSC obtained from teeth with periodontitis. In the present study, the aim was to compare the morphological features, stem cell marker (MSC) expression, proliferation rate, migratory and wound healing properties, osteogenic and chondrogenic differentiation potential of DPSCs obtained from periodontally healthy teeth (hDPSCs) and periodontitis affected teeth (pDPSCs). Methods: Dental pulp tissue was obtained from periodontally healthy volunteers (n = 3) and patients with periodontitis undergoing extraction of mobile teeth (n = 3). DPSC were isolated using the explant technique and cultured. All the experiments were performed at early passage (Passage 2), late passage (Passage 6) and after cryopreservation. Morphological features of the hDPSCs and pDPSCs were ascertained using microscopy. The expression of cell surface stem cell markers was assessed by the flow cytometry method. The proliferation and growth rate of the cells were assayed by plotting a growth curve from 0–13 days of culture. The migratory characteristics were assessed by wound scratch assay. Osteogenic and chondrogenic differentiation of the cells was assessed using standard protocols with and without induction. Results: DPSCs were successfully obtained from periodontally healthy teeth (hDPSC) and periodontitis-affected teeth (pDPSCs). The data suggests that there were no morphological differences observed in early passage cells between the two cohorts. Cryopreservation did change the morphology of pDSPCs. There was no significant difference in the positive expression of mesenchymal markers CD73, CD90 and CD105 in early passage cells. However, serial passaging and cryopreservation affected the marker expression in pDPSCs. A faint expression of hematopoietic stem cell markers CD34, CD45 and MHC class II antigen HLA-DR was observed in both the cell types. The expression of HLA-DR is upregulated in pDPSCs compared to hDPSC. A significantly slower growth rate and slower wound healing properties was observed in pDPSCs compared to hDPSC. In late passage and after cryopreservation, the migratory ability of pDPSCs was found to be increased drastically. There was no significant difference in osteogenic potential between the two cell types. However, the chondrogenic potential of pDPSCs was significantly lower compared to hDPSc. Yet, pDPSCs showed enhanced osteogenesis and chondrogenesis at late passage as well as after cryopreservation. Conclusion: The results of this novel study shed light on the isolation of viable DPSC from periodontitis-affected teeth. These cells exhibit a slower growth rate and migratory characteristics compared to their healthy counterparts. There was no difference in osteogenic potential but a reduction in chondrogenic potential was seen in pDPSCs compared to hDPSC. The findings reveal that DPSC from periodontitis-affected teeth presents an easy and viable option for regenerative medicine application. Some additional nutritive factors and protocols may be required to attain better regenerative benefits while using pDPSCs.

Abstract
Cemental tears are an important condition of relevance to Endodontics but are often overlooked. A cemental tear is the partial or complete detachment of the cementum from the cemento-dentinal junction or along the incremental line within the body of cementum. The limited attention received is most likely due to the limited awareness amongst dental professionals and challenges in accurately diagnosing them, resulting in misdiagnosis and erroneous treatment. The aim of this review is to describe the: (i) epidemiology and predisposing factors; (ii) clinical, radiographic and histological features and (iii) the clinical management and treatment outcomes of cemental tear. The review included 37 articles published in English that comprised eight observational studies and 29 case reports. The prevalence of cemental tears was reported to be lower than 2%; whilst the incidence remains unknown. Internal factors due to the inherent structural weakness of cementum and its interface with the dentine, and external factors that are associated with stress have been proposed as the two mechanisms responsible for the development and propagation of cemental tears. Predisposing factors that have been implicated were tooth type, gender, age, previous root canal treatment, history of dental trauma, occlusal trauma and excessive occlusal force; however, evidence is limited. Common clinical and radiographic manifestations of cemental tears resemble the presentations of primary endodontic diseases, primary periodontal diseases and combined endodontic-periodontal lesions. Clinical management tended to focus on complete removal of the torn fragments and periodontal treatment, often combined with regenerative treatment. In this article, a new classification for cemental tears is developed that consists of classes 0 to 6 and stages A, B, C and D based on the: (i) location and accessibility of the torn cemental fragment; (ii) the pattern and extension of the associated bony defect in relation to the root length and (iii) the number of root surface/s affected by the cemental tear/s and the associated bony defect. Recommendations for treatment strategies are also provided and linked to the classification to aid in streamlining the process of treatment decision making.

Abstract
Aim To assess the beneficial and adverse effects on the dental and periodontal issues of periodontal–orthodontic treatment of teeth with pathological tooth flaring, drifting, and elongation in patients with severe periodontitis. Materials and methods Nine databases were searched in April 2020 for randomized/non‐randomized clinical studies. After duplicate study selection, data extraction, and risk‐of‐bias assessment, random‐effect meta‐analyses of mean differences (MDs) and their 95% confidence intervals (CIs) were performed, followed by subgroup/meta‐regression analyses. Results A total of 30 randomized and non‐randomized clinical studies including 914 patients (29.7% male; mean age 43.4 years) were identified. Orthodontic treatment of pathologically migrated teeth was associated with clinical attachment gain (−0.24 mm; seven studies), pocket probing depth reduction (−0.23 mm; seven studies), marginal bone gain (−0.36 mm; seven studies), and papilla height gain (−1.42 mm; two studies) without considerable adverse effects, while patient sex, gingival phenotype, baseline disease severity, interval between periodontal and orthodontic treatment, and orthodontic treatment duration affected the results. Greater marginal bone level gains were seen by additional circumferential fiberotomy (two studies; MD = –0.98 mm; 95% CI = –1.87 to −0.10 mm; p = .03), but the quality of evidence was low. Conclusions Limited evidence of poor quality indicates that orthodontic treatment might be associated with small improvements of periodontal parameters, which do not seem to affect prognosis, but more research is needed.

The impact of splinting timepoint of mobile mandibular incisors on the outcome of periodontal treatment-preliminary observations from a randomized clinical trial. Clin Oral Investig 2021; 26:921-930.

Abstract
Objectives To compare the outcome of periodontal parameters in mobile mandibular incisors which were splinted before or after full-mouth disinfection (FMD). Materials and methods Thirty-four periodontitis patients with ≥ 1 mobile mandibular incisor (mobility degree II/III, clinical attachment loss (CAL) ≥ 5 mm, relative bone loss ≥ 50%) were randomly allocated to group A or B. Patients received periodontal treatment (PT) including splinting of teeth 33–43 before (A) or after FMD (B). Patient (age/sex/smoking status/systemic diseases/number of teeth) and tooth-related parameters (mean probing pocket depth (PPD)/CAL/oral hygiene indices; for the overall dentition and region 33–43) were assessed prior to PT and 12 months after FMD by a blinded examiner. Therapy-related information was added (group/antibiotic therapy/surgical intervention). Results Twenty-six patients (A: 12; B:14) were re-examined. Two patients of group B did not need splinting after FMD because of reduction in mobility after FMD. Regression analysis revealed a positive association of antibiotic therapy with CAL_overall, PPD_overall, and PPD_33-43 (p ≤ 0.01). There is a trend toward a higher reduction of periodontal parameters at teeth 33–43 in group A (PPD_33-43: − 0.91 vs. − 0.27 mm; CAL_33-43: − 1.02 vs. − 0.47 mm). Conclusions Teeth splinted before or after FMD show a significant improvement in periodontal parameters 12 months after FMD. Splinting after FMD offered the option to detect reduction in mobility. Clinical relevance Despite a higher, but not statistically significant, improvement in periodontal parameters on teeth splinted before FMD, the results do not indicate which timepoint of splinting is more beneficial. The decision for the therapeutic procedure should therefore be made individually.

Abstract
AIMS This paper explores the variables which influence decision-making processes in dentists providing dental care for people with disabilities under general anesthesia (GA). METHODS Face-to-face semi-structured interviews were undertaken on a purposive sample. Audio recordings were transcribed and checked for accuracy. Using thematic content analysis methods open codes were developed inductively. Codes were analyzed further by three authors adopting a deductive approach, leading to final coding, sorting and themes, subtheme and framework development. RESULTS Three themes emerged. The first theme explored Shared Decision Making, or lack thereof, as it influenced clinical reasoning. The second (Systematic, Analytical) and third (Intuition, and heuristics) themes explored features of clinical judgment as considered under dual process theory. Dentists primarily used intuitive decision-making processes and heuristic styled processes (or cognitive mental frames) assisted in intuition to extract teeth, without engaging type 2 processes. CONCLUSION The dentists experience subtle modifiers to their decision-making that ultimately promote extraction of teeth under GA for people with disabilities. Bias training, simulation and post-hoc reflection are examples of recommendations which may be used to improve decision-making in this area.

Abstract
Severe periodontitis is a highly prevalent dental disease. With the advent of implant dentistry, teeth are often extracted and replaced. Periodontal surgery, where indicated, could also result in increased trauma to the patient. This literature review discusses different treatment modalities for periodontitis and proposes a treatment approach emphasizing maximum preservation of teeth while minimizing morbidity to the patient. Scientific articles were retrieved from the MEDLINE/PubMed database up to January 2021 to identify appropriate articles that addressed the objectives of this review. This was supplemented with hand searching using reference lists from relevant articles. As tooth prognostication does not have a high predictive value, a more conservative approach in extracting teeth should be abided by. This may involve repeated rounds of nonsurgical periodontal therapy, and adjuncts such as locally delivered statin gels and subantimicrobial-dose doxycycline appear to be effective. Periodontal surgery should not be carried out at an early phase in therapy as improvements in nonsurgical therapy may be observed up to 12 months from initial treatment. Periodontal surgery, where indicated, should also be minimally invasive, with periodontal regeneration being shown to be effective over 20 years of follow-up. Biomarkers provide an opportunity for early detection of disease activity and personalised treatment. Quality of life is proposed as an alternative end point to the traditional biomedical paradigm focused on the disease state and clinical outcomes. In summary, minimally invasive therapy aims to preserve health and function of the natural dentition, thus improving the quality of life for patients with periodontitis.

Abstract
A hopeless tooth from a periodontal point of view, with severe bone resorption, mobility and abnormal tooth migration, is often extracted. In advanced cases, function and esthetics are impaired, and an interdisciplinary treatment is requested. Retaining or not these teeth is based on clinician judgment. A growing body of evidence claims that prognosis has great potential to be improved in a motivated patient with good oral hygiene and regular maintenance. This case report aims to present a periodontal regenerative technique combining enamel matrix protein derivatives and a particulated xenograft to treat intraosseous defects caused by periodontitis. The patient healed uneventfully, and no complications were recorded after the surgical procedure. To correct abnormal tooth migration and improve function and esthetics, orthodontic treatment was instituted. Tooth prognosis improved from hopeless to questionable. This approach extended the life span of a compromised tooth, improving periodontal support and decreasing tooth mobility. This could be an alternative to extraction and implant.

Abstract
AIM To compare the Oral Health-Related Quality of Life (OHRQoL) of patients with mobile mandibular incisors before and after full-mouth disinfection (FMD) with and without splinting. MATERIAL AND METHODS Thirty-four periodontitis patients with ≥1 mobile mandibular incisor (degree II/III) were randomly allocated to the test or control group. All patients received FMD and the test group additional splinting of teeth 33-43. OHRQoL was assessed before (BL) and 3 months after FMD (RE) using the Oral Health Impact Profile (OHIP)-14. Data were compared within and between the groups (Wilcoxon test/Mann-Whitney U test). RESULTS Twenty-eight patients (13 test group/15 control group) were re-evaluated. FMD led to a reduction of the mean probing pocket depth (PPD; in mm) (test group: BL-PPD 3.89 ± 1.03, RE-PPD 2.82 ± 0.53; control group: BL-PPD 3.58 ± 0.66, RE-PPD 2.77 ± 0.59; each p ≤ .001), the mean clinical attachment level (CAL; in mm) (test group: BL-CAL 5.22 ± 1.38, RE-CAL 4.79 ± 0.85; control group: BL-CAL 4.58 ± 1.10, RE-CAL 4.41 ± 0.96; each p ≤ .05), and the mean OHIP-14 summary scores (test group: BL-OHIP 21.7 ± 11.06, RE-OHIP 9.9 ± 8.96, p = .0046; control group: BL-OHIP 16.8 ± 8.27, RE-OHIP 11.7 ± 8.55; p = .0217). The reduction of the OHIP-G14 scores was considerably higher in the test group but statistically not significant (p = .080). CONCLUSIONS The results show a positive impact of non-surgical periodontal treatment on OHRQoL and a possible tendency for further improvement by splinting mobile mandibular incisors.

Abstract
INTRODUCTION Periodontal regeneration of maxillary molar proximal furcation defects are challenging due to limited access. While combination therapy of open flap debridement with barrier membrane, bone graft, and biologics are reported to be more successful than monotherapeutic approaches, combination therapy can be complicated and costly. CASE PRESENTATION A total of four teeth in three patients are presented to demonstrate radiographic bone regeneration of deep Class 2 maxillary molar proximal furcation defects (MMPFD) treated with microscope-assisted papilla preservation technique (PPT) and demineralized freeze-dried bone allograft (DFDBA). CONCLUSION(S) Radiographic bone regeneration of deep Class 2 MMPFD is possible with microscope-assisted PPT and DFDBA. Furthermore, treatment outcomes appear to be superior to those from previous clinical trials of Class 2 MMPFD treatment.

Abstract
BACKGROUND The present study focused on the inflammatory disease progress after periodontal defect induction and aimed to specifically determine periodontal tissue responses following dental plaque accumulation by ligatures on a site with/without standardized periodontal defect induction. METHODS After 1 month from extraction of the adjacent teeth, semi-circumferential defects were surgically created in the unilateral second and fourth premolars (test group), whereas no defects were being induced at the contralateral sites (control group). One week later, silk was used to ligate the tooth cervix at both sites to encourage the accumulation of dental plaque. Four weeks later, the tissue samples were collected for histological/histomorphometric and microarray analysis. Microbiological analysis was performed before defect induction and at ligatures, and after 4 weeks of dental plaque accumulation. RESULTS Remarkable inflammation was clinically and histologically observed in both groups after plaque accumulation, and the intrabony type of periodontal defect exaggerated inflammatory cell infiltration into the connective tissue layer. Expression of genes related to inflammation such as IL-1 was highly up-regulated in test sites. However, these inflammatory infiltrations did not invade to a boundary of periodontal ligament and connective tissue attachment in both groups, and histomorphometric results corresponds to these observational results. Bacterial findings also showed no significant differences in detected microbiome compositions between control and test groups at three-time points. CONCLUSION Intrabony defect might exaggerate the plaque-induced inflammation in the aspect of inflammatory cell infiltration and the related gene expression, but both dental plaque and the pre-existing periodontal defect negligibly disrupt periodontal attachment and the underlying alveolar bone.

Abstract
Periodontitis is a complex multifactorial disease that can lead to destruction of tooth supporting tissues and subsequent tooth loss. The most recent global burden of disease studies highlight that severe periodontitis is one of the most prevalent chronic inflammatory conditions affecting humans. Periodontitis risk is attributed to genetics, host-microbiome and environmental factors. Empirical diagnostic and prognostic systems have yet to be validated in the field of periodontics. Early diagnosis and intervention prevents periodontitis progression in most patients. Increased susceptibility and suboptimal control of modifiable risk factors can result in poor response to therapy, and relapse. The chronic immune-inflammatory response to microbial biofilms at the tooth or dental implant surface is associated with systemic conditions such as cardiovascular disease, diabetes or gastrointestinal diseases. Oral fluid-based biomarkers have demonstrated easy accessibility and potential as diagnostics for oral and systemic diseases, including the identification of SARS-CoV-2 in saliva. Advances in biotechnology have led to innovations in lab-on-a-chip and biosensors to interface with oral-based biomarker assessment. This review highlights new developments in oral biomarker discovery and their validation for clinical application to advance precision oral medicine through improved diagnosis, prognosis and patient stratification. Their potential to improve clinical outcomes of periodontitis and associated chronic conditions will benefit the dental and overall public health.

Abstract
AIM Smoking is a risk factor for periodontitis. This study aimed to evaluate the impact of smoking on clinical outcomes of non-surgical periodontal therapy. MATERIALS AND METHODS Electronic databases were searched to screen studies published before May 2020. The included studies had to have two groups: smokers (S) and non-smokers (NS) with periodontitis. The outcomes evaluated were differences between groups in probing depth (PD) reduction and clinical attachment level (CAL) gain after non-surgical periodontal therapy. Meta-regressions were conducted to evaluate correlations between outcomes and other contributing factors. RESULTS Seventeen studies were included. The post-treatment PD reduction in the S group was smaller than in the NS group (weighted mean difference in PD reduction: -0.33 mm, 95% confidence interval (CI): [-0.49, -0.17], p < .01). The CAL gain in the S group was also smaller than in the NS group (weighted mean difference in CAL gain: -0.20 mm, CI: [-0.39, -0.02], p < .01). Additionally, baseline PD significantly affected the difference in PD reduction between two groups. CONCLUSIONS Smoking negatively impacts clinical responses to non-surgical periodontal therapy. Smokers with periodontitis have significantly less PD reduction and CAL gain than non-smokers.

[PMID: 33011996 DOI: 10.1002/jper.20-0411] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 08/18/2020] [Accepted: 08/26/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND The aim of this study was to analyze the predictability of the Kwok and Caton periodontal prognosis system by investigating tooth survival within a 64-month period and to compare this to other well-established prognosis systems. METHODS This retrospective study included the records of patients who had a minimum of two dental exams at least 12 months apart at a single University-affiliated Dental Center. Data including patients' age, sex, length of follow-up period, initial tooth prognosis, revised tooth prognosis, tooth type, and number of teeth lost at the latest exam were recorded. Descriptive analysis was used for data interpretation. RESULTS A total of 4,046 teeth from 174 patients qualified for the study. Teeth with initial poorer prognosis had a higher chance of being extracted compared with those with a better initial prognosis. Tooth survival rate at the latest follow-up for those with an initial favorable, questionable, unfavorable, and hopeless prognosis was 97.9%, 90.7%, 62.5%, and 17.7%, respectively. Teeth initially assigned to a poorer prognosis category had a higher proportion that changed to a worse prognosis at the latest periodontal exam. CONCLUSIONS The Kwok and Caton prognosis system can predictably determine tooth survivability within a 5-year period. The defined categories of this prognosis system are more reliable than that of other systems in the short-term. However, long-term (>5 years) prediction accuracy of this prognosis system needs further investigation.

Abstract
BACKGROUND Periodontal disease is a major cause of tooth loss. Few studies have evaluated the residual area of the periodontal ligament in extracted teeth and, to the best of our knowledge, none from Latin America have done so regarding indications for extraction. The aim of this study was to evaluate the residual periodontal ligament (RPL) with respect to indication for extraction in a sample of teeth from a Brazilian Public Health Service district. MATERIALS AND METHODS All teeth extracted within the Public Health Service district of Santa Maria, Brazil, over a 5-month period were requested for analysis. A total of 414 teeth eligible for measurement were stained and evaluated for RPL using a stereo microscope. Participating Public Health Service dentists completed a questionnaire detailing demographic variables and indication for each extracted tooth. The percentage of RPL was determined for each tooth. Comparisons of RPL between teeth extracted on periodontal versus other indications were made using the Mann-Whitney test. RESULTS RPL averaged 34.8% for teeth extracted on periodontal indications versus 79.5% for other teeth (P ≤ 0.001). When considering teeth with an RPL ≥ 30% as possible to maintain, 189 (76%) of the teeth extracted on periodontal indications could have been maintained. When RPL cut-off limits of ≥ 40% or ≥ 50% are applied, 93 (37%) and 43 (17%) teeth, respectively, could have been maintained. CONCLUSION This study suggests that strictly based on RPL, a large number of teeth extracted on periodontal indications conceivably could be maintained.

Abstract
OBJECTIVE The aim of the present study was to compare in terms of pain perception the use of conventional anesthesia and a computerized system. MATERIALS AND METHODS Forty patients in need for extractions, dental restorative, or periodontal treatment bilaterally, were selected. Each patient served as his/her own control being subjected to two anesthesia techniques: conventional and electronically controlled anesthesia with Calaject® (Rønvig Dental MFG, Daugaard, Denmark). Each patient received both treatments in a blind way 1 week apart. The order was previously randomized. After performing the anesthesia (upper dental nerve, palatal posterior nerve, or inferior alveolar nerve), the patients evaluated their pain sensation with a visual analogue scale (VAS) (0-10). After treatment, the patients were asked about the presence of pain during the procedure. Finally, the patients selected their preference between the conventional and electronic anesthesia technique. Differences in assessment of pain's injection were analyzed using the Wilcoxon test and the Kruskal-Wallis test (α = 0.05). RESULTS The mean general pain experienced was 3.73 (1.55 SD) for the conventional anesthesia, and 1.95 (0.53 SD) for computerized anesthesia. Statistical differences (p < 0.05) were found. There was no difference between the treatments (p value = 0.061). Most patients did not feel any pain during the treatment. Finally, 92.5% of the patients preferred the electronic system. CONCLUSIONS Computerized anesthesia system produces significantly less pain compared with a conventional anesthesia syringe. Although both obtained sufficient anesthetic depth to perform treatments, the majority of patients chose electronic anesthesia as the most satisfactory. CLINICAL RELEVANCE Computerized anesthesia devices are valid and more comfortable alternative to conventional anesthesia.

Abstract
PURPOSE Socket augmentation decreases the magnitude of alveolar ridge resorption, but the literature is limited in respect to quantifying soft tissue remodeling. The aim of this study was to determine the volumetric and linear dimensional changes at the buccal surface for both hard and soft tissues after socket augmentation treated with a xenogeneic collagen matrix in combination with bone grafting. MATERIALS AND METHODS Twenty-four individuals indicated for tooth extraction were enrolled in this investigation. Each participant was randomly assigned to one of two groups: (1) deproteinized bovine bone + collagen plug, or (2) deproteinized bovine bone + xenogeneic collagen matrix. A cone beam computed tomography scan was taken prior to extraction and at 6 months postextraction. Intraoral scanning images were taken at baseline, 3 months, and 6 months postextraction. Hard and soft tissue analyses were performed to compare linear ridge remodeling and volumetric changes by noncontact reverse-engineering software. RESULTS Both groups showed bone and soft tissue remodeling. For hard tissue remodeling, there was no significant difference between the collagen plug and collagen matrix groups. For soft tissue remodeling, the collagen matrix group showed a reduced soft tissue loss compared with the collagen plug group. The volumetric analysis demonstrated that the mean buccal soft tissue volume loss for the collagen matrix group was 68.6 mm3 compared with 87.6 mm3 found in the collagen plug group (P = .009) over a 6-month period. CONCLUSION This clinical investigation provides early evidence of using the total tissue volume to compare soft and hard tissue remodeling after socket augmentation. The results of this study demonstrated that the use of a xenogeneic collagen matrix reduced the buccal soft tissue loss after tooth extraction, but additional studies are necessary to evaluate the clinical significance of soft tissue augmentation after tooth extraction.

Abstract
Background Periodontal regeneration can change tooth prognosis and represents an alternative to extraction in teeth compromised by severe intra‐bony defects. The aim of this study was to compare periodontal regeneration (PR) with tooth extraction and replacement (TER) in a population with attachment loss to or beyond the apex of the root in terms of professional, patient‐reported and economic outcomes. Methods This was a 10‐year randomized controlled clinical trial. 50 stage III or stage IV periodontitis subjects with a severely compromised tooth with attachment loss to or beyond the apex were randomized to PR or TER with either an implant‐ or a tooth‐supported fixed partial denture. Subjects were kept on a strict periodontal supportive care regimen every 3 months and examined yearly. Survival and recurrence analysis were performed. Results 88% and 100% survival rates were observed in the PR and TER groups. Complication‐free survival was not significantly different: 6.7–9.1 years for PR and 7.3–9.1 years for TER (p = .788). In PR, the observed 10‐year attachment gain was 7.3 ± 2.3 mm and the residual probing depths were 3.4 ± 0.8 mm. Recurrence analysis showed that the 95% confidence interval of the costs was significantly lower for PR compared with TER throughout the whole 10‐year period. Patient‐reported outcomes and oral health‐related quality‐of‐life measurements improved in both groups. Conclusions Periodontal regeneration can change the prognosis of hopeless teeth and is a less costly alternative to tooth extraction and replacement. The complexity of the treatment limits widespread application to the most complex cases but provides powerful proof of principle for the benefits of PR in deep intra‐bony defect.

Abstract
Mobility is a fundamental characteristic of mammalian teeth, and has been widely used to determine individual tooth prognosis. However, the direction and extent of tooth movement under functional loads are unknown. This study investigated maxillary molar mobility, alveolar bending, and periodontal space (PDL) fluid pressure during mastication and masseter muscle contraction in young pigs, along with PDL space measurements. Twelve three-month-old farm pigs were instrumented with some or all of the following: (1) ultrasonic crystals, one implanted into the pulp chamber of a deciduous maxillary molar and additional crystals glued onto its buccal and palatal alveolar plates; (2) rosette strain gauges affixed to the buccal and palatal of alveolar ridges; (3) a pressure transducer inserted into palatal alveolar bone facing the PDL. Tooth mobility, alveolar bending, and fluid pressure were simultaneously recorded during unrestrained feeding and subsequent masseter muscle stimulation. The PDL widths were measured using micro-CT. The results indicate that during the power stroke of mastication, (1) the molar displaced buccally and apically (192 ± 95 µm) regardless of the side of chewing; (2) compressive bone strain was greater on the buccal than on the palatal alveolar plate; and (3) PDL pressure increased during the power strok (3.63 ± 0.80 kPa). Masseter contraction produced similar results but with generally lower values. The PDL widths were larger than the range of tooth mobility, and showed no correlation with the mobility. Thus occlusal function causes buccal tipping and intrusion of maxillary molars with concomitant compression of the buccal alveolar plate and raised pressure within the PDL space.
