The purpose of this study was to evaluate factors associated with temporomandibular disorder (TMD) in children. TMD clinical signs were evaluated using the Research Diagnostic Criteria for TMD (RDC/TMD; axis I), and subjective symptoms were evaluated using a structured questionnaire. Eighty-two children were selected, 40 with TMD (19 boys and 21 girls, mean age 9.84 ± 1.53 and 9.71 ± 1.30 years, respectively) and 42 without TMD (21 boys and 21 girls, mean age 10.27 ± 1.63 and 9.9 ± 1.37 years, respectively). Intra-and extra-oral examinations were carried out to determine the myofunctional characteristics of the masticatory system. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression. Data were analyzed using descriptive statistics and bivariate analysis followed by multiple logistic regression (α = 0.05). In bivariate analysis, the variables of open lips, anxiety, and depression had a p value < 0.15 and were entered into the multivariate logistic regression model. The most significant predictor factors were the presence of open lips (odds ratio = 5.42, p = 0.034) and anxiety (odds ratio = 18.59, p < 0.001). Thus, anxiety levels and open lips were associated with TMD in children. Owing to the cross-sectional design of the present study, the associations observed may have a bidirectional relationship.

Abstract Objective: To evaluate the effect of 1% chlorhexidine (CHX) gel on mentally handicapped children (n=11) highly infected with Streptococcus mutans (SM) and evaluate the re-colonization time of this bacterium after the treatment period.. Material and Methods: Before CHX treatment, saliva samples were collected to establish baseline saliva SM levels. CHX gel was daily applied for 5 min, for 7 consecutive days. Saliva samples were then collected after 7, 30, 60, 90 and 120 days to evaluate SM oral recolonization. Data were analyzed by the Wilcoxon test (α=0.05). Results: When compared to baseline (5.7 / 3.0 x 105), the collection performed 7 days after CHX treatment (0.06 / 0.2 x 105) showed a significant reduction (P <0.05) in SM saliva levels (mean / s.d., CFU ml-1). In subsequent collections, a gradual SM re-colonization was observed, and after 60 days of treatment, the levels of this bacterium (0.8 / 0.9 x 105) no longer statistically differed from SM levels considered high risk to caries (105) (P> 0.05). Conclusion: Treatment with CHX gel for 7 days was effective in reducing the SM levels of mentally handicapped children and should be repeated after 60 days to control the risk of caries in these children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
