title: Dental caries experience in patients with aggressive periodontitis compared to those with chronic periodontitis.
abstract: OBJECTIVE
  It has been reported that caries prevalence in patients with aggressive periodontitis (ie, juvenile periodontitis) might be higher than that in matched controls. However, the available results are inconclusive. The aim of this study was to assess this relationship by comparing caries experience among subjects with generalized aggressive periodontitis (AgP) and those with chronic periodontitis (CP) and to identify reasons for tooth loss in both groups.
  
  
  METHODS
  A convenient sample of subjects with AgP (210) and CP (332) was evaluated for decayed, missing, and filled teeth (DMFT) by both clinical and radiographic methods. Statistical analysis was performed by t test and ANOVA.
  
  
  RESULTS
  The AgP subjects have significantly less caries experience than the CP subjects older than 20 (P < .001). Tooth loss was mainly due to periodontal disease in AgP subjects and caries in CP subjects.
  
  
  CONCLUSIONS
  Subjects with AgP have significantly less caries experience than subjects with CP over 20 years of age (P < .001).
