Abstract
OBJECTIVE: To evaluate the prevalence of temporomandibular dysfunction (TMD) and its association with perceived stress and common mental disorder (CMD) in academic students. METHODS: This is s transversal observational study conducted at Universidade de Minas Gerais, Divinópolis Unit, in health science courses. To investigate the prevalence of TMD, the anamnestic index by Fonseca was used. Stress was assessed by the perceived stress scale, translated and adapted for the Brazilian population in 2006. To track CMD, we used the Self-Reporting Questionnaire (SRQ-20). Data were analyzed using SPSS version 13.0, adopting a 5% significance level. RESULTS: The prevalence of TMD in the sample was 71.9%, distributed as follows: Light TMD (50.0%), moderate (16.4%) and severe (5.5%), being more frequent among women (76.4%). Common mental disorders were present in 29.9% of participants. The average perceived stress was 30.9. CONCLUSION: The results of this study allow us to conclude that there is a statistically significant correlation between TMD and variables such as parafunctional habits, perceived stress and CMD. Level of Evidence II, Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).
