title: Prevalence of and risk indicators for chronic periodontitis in males from Campeche, Mexico.
abstract: OBJECTIVE
  Determining the prevalence, severity and extension of chronic periodontitis and identifying risk indicators amongst policemen in Campeche, Mexico, using an electron probe.
  
  
  METHODS
  A cross-sectional study of a convenience sample of 161 men was conducted. A case of periodontitis was defined as a participant having clinical attachment loss in at least one (3) 4 mm site. Every periodontal site in the mouth was measured by a standardized periodontist using a Florida Probe System. STATA 8.2 was used for bivariate and multivariate statistical analysis, using logistic binary regression. RESULTS Mean age was 38.36+/-10.99 years. 23,622 periodontal sites were available for examination. Mean (SD) teeth and sites examined per person were 24.45+/-4.63 and 146.72+/-27.80, respectively. Periodontitis prevalence was 62.7%. Periodontitis severity was 2.9 mm and extent was 53.7%. Adjusted for alcohol intake, factors associated with periodontitis prevalence were being older ((3)35 years; OR=2.08; CI95%=1.05-4.10), smoking (current/former; OR=2.22; CI95%=1.06-4.77) and gingivitis (presence; OR=3.35; CI95%=1.34-8.42).
  
  
  CONCLUSIONS
  Many study participants had poor periodontal conditions, with substantial overall prevalence of periodontitis. Older age, tobacco use and the presence of gingivitis were factors associated with periodontitis prevalence.
