Prevalence and impact of signs and symptoms of temporomandibular disorders in dental students and faculty.

Objectives: Temporomandibular disorders (TMD) affect individuals undergoing increased stress, for example, dental professionals. No study to date has compared dental students and faculty in TMD manifestation. This cross-sectional study compared prevalence, risk factors, and impact on daily activities of self-reported TMD signs/symptoms between dental students and faculty at a predoctoral dental school, and between preclinical (first- to second-year) and clinical (third- to fourth-year) students.
