As yet, research results on the relationship between obesity and caries in children and adolescents have been inconclusive. This study aimed to evaluate the association between caries and obesity in adolescents.This was a cross-sectional study of a convenience sample of 187 Puerto Rican adolescents aged 13–19 years, attending, among them, five high schools. Each participant received dental exams for caries using the criteria of the International Caries Detection and Assessment System (ICDAS), had his or her body mass index (BMI) determined, and took a 19-item risk-factor questionnaire. The Significant Caries (SiC) index (for DMFT) was calculated to compare obese and healthy adolescents. Statistical analysis was performed using descriptive and inferential statistics.Nearly 60% of the sample population was female, with a mean age of 15.7 (±1.25). The mean BMI percentile was 72.24 (±28.78); 48.66% of the participants had a healthy weight, 19.79% were overweight, and 30.48% were obese. Dental caries was observed in 68% of the participants; the mean caries indexes D3-6MFS was 5.17(±5.92) and mean D3-6MFT 3.59 (±3.97). No significant differences were found between caries indexes and obesity status (P > 0.05). The Median (p25, p75) SiC index among overweight/obese adolescents was 9.5 (7, 12), whereas for healthy weight/underweight participants was 7 (5, 8) (p < 0.005).Based on the limited number of participants, no association was found between dental caries (D3-6MFS and D3-6MFT) and obesity (BMI) among adolescents.","PeriodicalId":502488,"journal":{"name":"Frontiers in Dental Medicine","volume":"47 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141798984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A preoperative soft tissue width <2 mm, with probing pocket depth <5 mm, edema and inflammation and bleeding on probing was determined A digital impression was taken of both donor and recipient locations using an intraoral scan, generating a Standard Tessellation Language digital file both preoperatively (STL1) and after 1 week (STL2), 1 month (STL3), 3 months (STL4), and 6 months (STL5) of follow-up. Afterwards, the digital files (STL1-STL5) were aligned using a reverse engineering morphometric software, and Student's t-test was used to analyze changes in volume at the donor and recipient locations. Additionally, widths were measured both clinically and digitally so as to compare the reliability of these measurement techniques. The repeatability and reproducibility of both these measurement techniques were also analyzed using Gage R&R statistical analysis.Gage R&R found that total variability of the digital technique was 0.6% (among the measures of each operator) and 7.6% (among operators); as variability was under 10%, the results were repeatable and reproducible. In addition, there were statistically significant differences between donor and recipient locations in healing process volume (mm3) after one week (p = 0.0110), one month (p = 0.0007), three months (p < 0.0001) and six months (p = 0.0004) of follow-up.The digital measurement technique provided accurate, repeatable, and reproducible results when analyzing the volumetric and lineal measures of the healing process in both the donor and recipient locations of a free gingival graft surrounding a dental implant, with significantly higher tissue volume in the recipient location.","PeriodicalId":502488,"journal":{"name":"Frontiers in Dental Medicine","volume":"349 17‐18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neves, Viktor Savchenko, James Daly, Paul Sharpe","doi":"10.3389/fdmed.2024.1415960","DOIUrl":"https://doi.org/10.3389/fdmed.2024.1415960","url":null,"abstract":"Periodontal disease (PD), a widespread non-communicable disease, affects over 90% of the global population with no known cure. Current management strategies focus on stabilization of disease progression, which is successfully achieved to a limited extent. Yet the never-ending battle of bacteria and the gingiva involves a complex interplay between genetic, microbial and environmental factors, demanding innovative approaches to improve prevention and stabilisation of this disease. Glucose is the body's source of energy and research has shown that dysregulation of the glucose metabolism impacts PD establishment and progression, as well as impact development of systemic non communicable diseases. Metformin, a drug known for its efficacy in diabetes treatment via controlling glucose metabolism, also demonstrated cardioprotective effects, increased longevity, and anti-inflammatory properties. Metformin has been used in gel format in clinical trials for PD non-surgical treatment, however, its systemic use in normoglycemic individuals with PD is less explored. A recent study presented compelling evidence of Metformin's preventive potential, impacting PD and markers of systemic health involved in metabolic health liked to improvement of lifespan. Therefore, this review discusses the aspects of ageing as a concept in the periodontium and the potential benefits of modulating glucose metabolism through Metformin to prevent PD, indirectly preventing systemic conditions involved in multi-morbidity, addressing a critical gap in current management. It also examines the choice between implementation of behaviour change and/or medication as strategy to add to current oral hygiene strategies. Finally, it discusses the ethical implications of prescribing systemic medication in dentistry.","PeriodicalId":502488,"journal":{"name":"Frontiers in Dental Medicine","volume":"9 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141847101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional destructive laboratory tests often fail to accurately evaluate the timing and failing crack formation of these brittle materials. Non-destructive testing methods, such as acoustic emission testing (AET), offers an alternative by providing valuable data on material properties without causing damage to the samples.The in vitro study aimed to evaluate the sensitivity of a sound harvesting modified acoustic emission testing by comparing the fracture resistance of posterior monolithic zirconia crowns (MZCs) measured via the modified set up with that of a conventional fracture toughness test.A modified acoustic emission set up, the sound harvesting test (SHT), featuring a condenser microphone, an amplifier, a custom audio chipset and a cut-off switch integrated into a universal testing machine, was compared to a conventional fracture toughness test to measure fracture loads on 50 posterior monolithic zirconia crowns divided in two groups.The sound harvesting test recorded a mean fracture load of 1,108.99 N, significantly less than the 1,292.52 N measured with the conventional test, indicating a more sensitive detection of fractures. Statistically significant differences (p < 0.05) were observed between the two groups.Despite its limitations, the study suggests considering sound harvesting testing as an potential alternative for fracture load testing of dental brittle materials due to its ability to identify failures at lower loads enhancing therefore a more accurate evaluation of the behavior of dental materials. However, further testing on a broader range of dental materials is warranted to improve result accuracy and applicability.","PeriodicalId":502488,"journal":{"name":"Frontiers in Dental Medicine","volume":"150 9‐12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Periodontitis is a chronic multifactorial disease induced by a dysbiotic microbiota in a susceptible host whilst diabetes is an established risk factor for periodontitis. Diabetes has been shown to alter the subgingival microbiota into distinct microbial communities which favours the shift towards disease. It is these very distinct subgingival microbiota that are believed to contribute to the high prevalence and severity of periodontitis in diabetic patients. This dysbiotic microbiota constitute traditional periodontal pathogens which include among others the red complex triad (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia), Aggregatibacter actinomycetemcomitans, the orange complex (Fusobacterium nucleatum, Prevotella intermedia etc.) and other emerging pathogens such as Fa that were previously unrecognised as role players in the pathogenesis of periodontitis. Fa is an asaccharolytic anaerobic gram-positive rod (AAGPR) currently considered to be one of the potential drivers of periodontitis progression and worsening through its unique virulence characteristics. Various mechanisms through which Fa contributes to the pathogenesis and severity of periodontitis have been reported. The mechanisms involved in the bidirectional relationship between periodontitis and diabetes are continuously being explored in order to enhance individualised preventative and management approaches in affected patients. This review aims to report on this emerging periodontal pathogen and its capacity to influence dysbiosis within a complex subgingival microbial community; including its potential role in the bidirectional relationship between diabetes and periodontitis. This review will highlight Fa as a potential prognostic indicator for disease worsening, which will help improve management protocols for periodontitis and diabetes.","PeriodicalId":502488,"journal":{"name":"Frontiers in Dental Medicine","volume":"51 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141109306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
