Abstract

Background: There is little evidence on the prevalence of bruxism in adult Chilean population and its related factors.  Objective: To describe the prevalence of self-reported bruxism manifestations and to explore related factors.   Method: A cross-sectional study was carried out in adult population who attended diagnosis at San Bernardo’s Health Center (Universidad de los Andes).A questionnaire was applied by trained interviewers. The questions were previously checked in a similar population focus group to verify their understanding. Several sociodemographic characteristics were evaluated, as well as habit records, medicine consumptions, general diseases, among others. They were asked if any health professional had told them if they had bruxism and if they clenched or ground their teeth. Results were recorded in Epidata and analysed with Stata 14.2. It was estimated a logistic regression model for assessment the relationship adjustment for age and an Odds Ratio (OR) and confidence interval (CI 95%) was reported. Scientific-Ethic Committee from the Faculty of Medicine approved the protocol and informed consent document. Conclusions: We observed a prevalence of self-reported manifestations of bruxism greater than 50% of the participants, finding a positive association between this result and age, depression, poor sleep, medicine consumption, and some reflux symptoms.
