Prevalence of periodontitis and DMFT index in patients with Crohn's disease and ulcerative colitis

Abstract

Aim: To compare the prevalence of periodontal disease and the decayed, missing and filled teeth (DMFT) index in patients with Crohn's disease (CD) and ulcerative colitis (UC) with those without these diseases.

Material and methods: Ninety-nine CD (39.0 SD+/-12.9 years), 80 UC (43.3 SD+/-13.2) and 74 healthy controls (40.3 SD+/-12.9) were compared for DMFT index and presence of periodontitis. Probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), plaque and DMFT index were measured on all subjects. The presence of periodontitis was defined as having CAL > or =3 mm in at least four sites in different teeth.

Results: Significantly more patients with UC (90.0%; p<0.001) and CD (81.8%; p=0.03) had periodontitis than controls (67.6%). Among smokers, UC patients had significantly more periodontitis. CD had a greater mean DMFT score (18.7 versus 13.9; p=0.031) compared with controls and UC had greater median PPD (2.2 versus 1.7 mm; p<0.0001) than controls. Among non-smokers, CD (2.4 mm; p<0.0001) and UC showed deeper pockets (2.3 mm; p<0.0001) compared with controls (1.5 mm). UC had a greater mean DMFT score (15.3 versus 12.1; p=0.037) compared with controls.

Conclusions: CD and UC patients had higher DMFT and prevalence of periodontitis than controls, but smoking was an effect modifier.
