Prevalence of bruxism in undergraduate students.

Objective: The aim of this study was to determine the prevalence of bruxism in students at the Federal University of the Jequitinhonha and Mucuri Valleys in Brazil. The secondary objectives were to identify the factors associated with bruxism; prevalence of dental wear; and to distinguish the signs and symptoms of temporomandibular dysfunction when present, and verify its relationship with bruxism.

Methods: Two hundred fifty-three students (106 males, 147 females) were clinically examined and answered a questionnaire.
