AbstractPurpose: The aim of this study was to assess the prevalence of bruxism and emotional stress in military policemen and test their association. Methods: A cross-sectional study was conducted in members of the Military Police of the State of Maranhão in São Luís, MA. Sample was composed by 81 male subjects (mean age = 33.5 years). Bruxism was diagnosed according to clinical criteria – presence of aligned wear facets associated with at least one of the following signs and symptoms: selfreport of bruxism grinding sounds, pain to palpation of the masseter and temporal muscles, report of morning masticatory muscle discomfort and/or masseter muscle hypertrophy.

The stress prevalence in individuals with bruxism was significantly higher than that in subjects without bruxism (Chi-square test, P=0.003).
