title: Prevalence of dental caries and periodontal disease in patients with inflammatory bowel disease: a case-control study.
abstract: OBJECTIVE
  Previous reports suggest a higher incidence of dental caries in patients with inflammatory bowel disease (IBD) and similarities in the immunopathogenesis of IBD and periodontitis. This study assessed the prevalence of periodontal disease and caries in patients with IBD.
  
  
  METHODS
  In the present case-control study, 62 patients seeking treatment of IBD and 59 matched healthy controls of a dental practice were clinically examined. Oral soft-tissue alterations, the decayed, missing and filled tooth surface (DMF-S) index, dentine caries, plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment loss (CAL) were evaluated in each patient and in the controls.
  
  
  RESULTS
  Patients with IBD showed a significantly higher number of oral manifestations compared with controls. The DMF-S index showed no significant differences, but there was a significantly higher number of subjects with dentine caries in patients with IBD. The mean PPD in patients with IBD was 2.08 versus 2.23 mm in controls (p=0.014). Compared with controls, patients with IBD had more sites with CAL of at least 4 mm (81% versus 64% in controls, p=0.07) and 5 mm (63% versus 46%, p=0.07), respectively.
  
  
  CONCLUSIONS
  The results of this case-control study demonstrate a higher frequency of dentine caries in patients with IBD but the periodontal findings showed no distinct differences between cases and controls.
