Dental students had a high frequency of TMDs and bruxism.

This study investigated the frequency of temporomandibular disorders (TMDs) in dental students, and evaluated the association between TMDs, psychological states and oral health-related quality of life (OHRQoL). Two hundred and ninety-three dental students completed the Symptom Checklist 90-Revised (SCL-90-R) and Oral Health Impact Profile 14 (OHIP-14) questionnaires and underwent a clinical examination according to diagnostic criteria for TMDs. TMDs were detected in 46% of the dental students. OHIP-14 scores of students with TMDs were significantly higher than scores for students without TMDs. Significant differences were observed in all SCL-90-R scores among students with and without TMDs, except for phobic anxiety and additional SCL-90-R subscale scores. The prevalence of myalgia was significantly higher in clinical students (27%) than in preclinical students (16%). OHIP-14 scores of clinical students were significantly higher than preclinical students.
