ABSTRACT
OBJECTIVE: Evaluate the association between oral health-related quality of life (OHRQoL) and self-reported symptoms of TMD. METHODS: Representative samples of older adults (≥60 years) were included (n = 569). Both TMD symptoms and OHRQoL were assessed by Fonseca Anamnestic Index (FAI) and Oral Health Impact Profile-14 (OHIP-14), respectively. Prevalence (those answering "frequently" or "always" in at least one question), severity (total means scores), and extent (number of questions answered as "frequently" or "always") of OHRQoL were estimated. RESULTS: Overall, 33.4% and 9.5% had mild or moderate/severe TMD symptoms. Those with any symptom of TMD had a prevalence ratio (PR) 38% higher for the worst OHRQoL (95% confidence interval [95%CI]:1.04-1.82) compared to those without TMD symptoms. Worst OHRQoL were observed for those with mild (PR:1.35; 95%CI:1.01-1.81) and moderate/severe TMD (PR:1.53; 95%CI:1.04-2.26). Similar results were detected in the severity and extent of OHRQoL. CONCLUSION: Severity TMD was associated with worse ORHQoL.
ABSTRACT
OBJECTIVE: This study aimed to evaluate the prevalence and factors associated with self-perception of teeth alignment and colour in adolescents. METHODS: This cross-sectional study was carried out in public and private schools in Passo Fundo, Brazil. A representative sample of students aged 15 to 19 years were included. The outcome of this study was self-perception of teeth alignment and colour according to selected items from a structured and validated questionnaire (the Child's and Parent's Questionnaire about Teeth Appearance). Bivariate and multivariable analysis, using Poisson regression with robust variance, were used. A P value <.05 was established for statistical significance. RESULTS: The study included 736 adolescents. The worst self-perception of teeth alignment and colour was observed in 46.5% (n = 342) of the adolescents. Nonsmokers presented a prevalence ratio (PR) 29% lower (95% CI, 0.57-0.89) for the worst self-perception of teeth alignment and colour when compared to smokers/former smokers. Adolescents with highly educated mothers presented a lower prevalence of negative self-perception than those with mothers with a low level of education (PR: 0.66; 95% CI, 0.51-0.86). Presence of orthodontic treatment with (PR: 0.76; 95% CI, 0.62-0.94) or without (PR: 0.61; 95% CI, 0.46-0.76) tooth whitening were associated with better self-perception of teeth alignment and colour. CONCLUSIONS: Exposure to smoking and lower maternal level of education were associated with worse self-perception of teeth alignment and colour in adolescents. A history of orthodontic treatment with or without tooth whitening was associated with a lower concern with aesthetics.
