Objectives: To assess clinical, behavioral and socioeconomic factors associated with nonuse of dental services by schoolchildren.
Methods: A cross-sectional school-based study with 1211 children aged 8-12 years was carried out in Pelotas, Brazil. The outcome (never having had a dental appointment) and independent variables were collected through interview with parents and children, including sex, age, parent's schooling, family income, self-perception about oral health, and dental fear. Dental caries was assessed by clinical examination performed at schools.
Results: 291 (24.3 %; 95 % CI 22.0-26.9) of the children had never visited a dentist. Multivariate Poisson regression analysis showed that the outcome was associated with children from mothers with little education (≤0.001), from public schools (≤0.001), from crowded households (≤0.001), who had no caries (≤0.001), who had dental fear (≤0.001), and who started oral hygiene later (0.04).
Conclusions: Despite the extensive increase in oral health coverage, especially in the public system in the last years in Brazil, there is still an unassisted portion of the population of schoolchildren. It was observed that socioeconomic, behavioral, and clinical factors influenced the nonuse of dental services.

Association Between Serum Levels of Perfluoroalkyl and Polyfluoroalkyl Substances and Dental Floss Use: The Double-Edged Sword of Dental Floss Use-A Cross-Sectional Study.
J Clin Periodontol
January 2025
Department of Pediatric Surgery, Children's Medical Center, The First Hospital of Jilin University, Changchun, China.
Background: Although evidence suggests that dental floss contains perfluoroalkyl and polyfluoroalkyl substances (PFASs), it is still uncertain whether the use of dental floss contributes to an increased risk of PFAS exposure.
Methods: We analysed data on serum PFAS concentrations and dental floss usage in a cohort of 6750 adults who participated in the National Health and Nutrition Examination Survey (NHANES) from 2009 to 2020. In our study, we used logistic regression, a survey-weighted linear model, item response theory (IRT) scores, inverse probability weights (IPWs) and sensitivity analysis to assess the potential impact of dental floss usage on human serum PFAS levels.
Maxillofacial trauma patterns and risk factors in 2-wheeler riders: A non-urban South Indian epidemiological study.
Traffic Inj Prev
December 2024
Department of Oral and Maxillofacial Surgery, Kamineni Institute of Dental Sciences, Nalgonda, Telangana, India.
Objective: The prevalent reliance on 2-wheelers as a preferred mode of private transportation in rural and semi-urban regions and the various associated social and material factors put riders at significant risk for road traffic accidents causing maxillofacial trauma. This epidemiological study aims to investigate these factors and their influence on patterns of maxillofacial injuries among 2-wheeler riders in semi-urban and rural areas of South India.
Methods: Data from all cases with maxillofacial injuries over 6 years were collected retrospectively, including demographic characteristics, accident specifics, helmet use, injury patterns, and management.
Association between warfarin use and thromboembolic events in patients post-Fontan operation: propensity-score overlap weighting analyses.

Article Synopsis
- A study aimed to evaluate the effectiveness of warfarin in preventing thromboembolic events in patients who have undergone a Fontan operation compared to those not using warfarin.
- The research analyzed data from 2007 patients over a follow-up period of 2.1 years, finding no significant differences in the incidence of thromboembolic or bleeding events between warfarin users and non-users.
- The findings suggest that routine use of warfarin for thromboembolism prevention in pediatric Fontan patients may not be necessary, indicating the need for further research on this topic.
Article Synopsis
- Periodontitis is a common inflammatory disease that can severely impact oral and overall health, and while traditional smoking is a known risk factor, the effect of e-cigarettes on gum health is not well understood.
- This systematic review analyzed data from twelve studies comparing periodontal outcomes between e-cigarette users and non-users, noting that e-cigarette users had a significantly lower bleeding on probing (BOP) score.
- The research suggests no strong evidence linking e-cigarette use to major negative impacts on periodontal health, but further comprehensive studies are needed to assess long-term effects and clarify any potential risks.
