title: No association between periodontal disease and GHQ-12 in a Brazilian Police population.
abstract: OBJECTIVE
  We attempt to investigate a possible association between periodontal disease (PD) and mental disorders (MD) in a population of Brazilian Police.
  
  
  METHODS
  From a total study population consisting of 803 policemen, 345 police officers were obtained by a sample calculation using the finite population correction who were randomly selected in Montes Claros, Minas Gerais, Brazil. Patients who had been prescribed steroids or those diagnosed with diabetes and cardiovascular diseases were excluded from this study. The General Health Questionnaire (GHQ-12) was used to assess mental disorders. Odds ratios (ORs) for periodontal diseases severity and their respective 95% confidence intervals (CIs) were estimated. The risk of advanced scores in Clinical Attachment Level (CAL) and Community Periodontal Index (CPI) were estimated using Poisson Regression analyses.
  
  
  RESULTS
  Only smoking and age were associated with severity in CAL and CPI index. No relation between MD and PD was observed even in different positions within the police department.
  
  
  CONCLUSIONS
  It was not observed relation between GHQ-12 and the incidence of Periodontal Disease in a Brazilian Police population. Classical factors like age and smoking, however, were associated with CAL and CPI index higher scores in this population.
