Prevalence of oral lesions in inflammatory bowel disease

Objective: To obtain precise data on the prevalence of oral lesions in inflammatory bowel disease (IBD). Methods: Oral lesions were carefully sought in a consecutive series of 198 Italian IBD outpatients, 77 with Crohn's disease (CD) and 121 with ulcerative colitis (UC); 89 subjects with functional intestinal motility disorders served as controls. Results: The oral lesions detected were angular cheilitis (in 7.8 % of CD patients, 5 % of UC patients, and 0% of controls (p < 0.05, patients vs controls), lichen (6.5, 5.8, and 3.3%, respectively, p = not significant), aphthous ulcers (5.2, 5.8, and 5.6%, respectively, p = not significant), candidiasis (5.2, 0.8, and 0%, respectively, p < 0.05, CD patients vs controls), benign tumors (5.2, 0, and 7.8%, respectively, p < 0.05, patients vs controls), leukoplakia (5.2, 11, and 3.3%, respectively, p = not significant), and, less frequently, glossitis and herpes labialis. No specific CD oral lesions were observed in this series. No correlation was found between clinical disease activity and frequency of oral lesions. Conclusions: Aphthous ulcers are not common in IBD patients. Oral candidiasis is more frequent in CD than UC patients and controls.
