Evaluation of the relation between TMJ disorders and oral habits on the 1st year students at a faculty of dentistry: A questionnaire study

Abstract

Background: The aim of this study was to evaluate the problems of temporomandibular joint (TMJ) problems on Faculty of Dentistry Students and to determine whether these problems were related to oral habits. Methods: The prevalence and severity of TMJ disorders were evaluated using the Fonseca questionnaire for 63 students (37 females & 26 males) studying at the Faculty of Dentistry in Harran University. In addition, the Oral Behavior Checklist (OBC) questionnaire was applied to the same students in order to analyze the relationship between TMJ problems and oral habits. Results: According to the results of Fonseca questionnaire, it was revealed that 73% of the participants had some degree of TMJ problems. When the female and male participants were investigated separately, it was observed that 73.2% of the male participants and 73% of the female participants had some degree of TMJ problems. The correlation between OBC and Fonseca was found to be positive. Conclusion: In our study, it was revealed that the increase in oral habits also increased the prevalence of TMJ disorder.
