A selection was made of 394 policemen of the male sex, belonging to the Inland Police Command - 2, Campinas city - 8P, ranging ftom 20 to 51 years of age. The volunteers were diagnosed as having bruxism according to the following criteria: presence of aligned wom facets grade 1, 2 or 3 in the ordinal scale of wear severity, allied to the current presence of at least one of the following signs or symptoms: self-report of bruxism during sleep and/ or whi1e awake; soreness on palpation the masseter and/ or temporal musc1es, discomfort in the jaw musculature on waking; and/or hypertrophy of the masseter muscle. In order to diagnose stress, the 8tress 8ymptoms Inventory (881) was applied, which allows the presence of stress to be identified. The prevalence of bruxism found in this study was 50.25% (198 of the 394 selected policemen). However, in un-stressed policemen (n=214), the presence ofbruxism was 42.% (90), whi1e in the group ofstressed policemen (n=180), the percentage of patients diagnosed as having bruxism was 60,0% (108), which indicates an increase of approximately 42.5% in this parafunctional habito Emotional stress was noted in 45.69% ofthe 394 policemen. However, it was noted that in the non-bruxism policemen (196), 36.7% (72) were stressed, whi1e in the bruxism patients (198), the percentage of volunteers with stress was 54.5%, configuring an increase of 48.5% in the ftequency of stress. The statistica1 analysis ofthe results showed, by means of the Chi-square test at 95% significance, that there was a significant association (p=0.0004) between bruxism and emotional stress. With regard to the job activity exercised by the policeman (administrative or operational), no significant association was found between emotional stress and job activity (p=O.382) or between bruxism and job activity (p=O.611).
