The interaction between Temporomandibular disorders (TMD) and otalgia is, even nowadays, a reason for speculation and hypotheses raising. Several researchers suggest causes, consequences and alleged treatments. Study design: This is an epidemiological, sectional cohort study of prevalence. Aim: The study demonstrates the prevalence of patients harboring TMDs in an otorhinolaryngology department. Material and methodos: During a two-month period, 221 patients from the Otorhinolaryngology Department of the Hospital da Cidade de Passo Fundo, State of Rio Grande do Sul, Brazil were analyzed. A previously validated questionnaire was applied for data collection. Results: In the present study, the need for dental assessment was observed in 48 patients ( 21.72%). In this group there were 35 female (72.9%) and 13 males (27.1%). Only 15 patients (7.24%) were entirely free of TMD symptoms. The remaining patients reported the following TMD symptoms: headaches: 34.39%, neck and shoulder pain: 28.50%, pain on the ear region: 30.32% and joint noises in 23.98%. Conclusion: The prevalence of Temporomandibular disorders was 21.72%, being significantly higher among female subjects (p:0.0001). The prevalence regarding the indexes, was: TMD absent: 37.56%; mild TMD: 40.72%; moderate TMD 19% and severe TMD: 2.72%.

To estimate the prevalence of temporomandibular joint (TMJ) pain symptom and to verify its association with predisposing or perpetuating factors. Cross-sectional study of adult patients, with 488 medical records of patients assisted at the Clinics of the School of Dentistry of IMED, in the city of Passo Fundo, RS, Brazil. The data were collected through the anamnestic record based on patient self-report. The chi-square test at 5% significance level was used to evaluate the relationship between the outcome of TMJ pain and the variables. In addition, bivariate and multivariate Poisson analyses were performed at 5% significance level to confirm the associations, including to the multivariate analysis the variables with p ≤ 0.20 in the bivariate analysis. The prevalence of TMJ pain in this adult population was 21.52% (n=105). There was an association between TMJ pain and the variables of teeth clenching and habit of biting objects (p<0.05). This study concluded that the prevalence of TMJ pain symptom agrees with the mean prevalence found in the literature for studies with convenience samples, and teeth clenching and the habit of biting objects may represent perpetuating or predisposing factors for such condition.
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.
