Objectives: Crohn's disease and ulcerative colitis are forms of inflammatory bowel disease. Both conditions are characterized by chronic inflammation of the gatrointestinal mucosa, in which in some cases extraintestinal manifestations also occur. Oral manifestations of Crohn's disease are: orofacial edema, patchy mucous membranes, cobblestone appearance of the mucosa, hyperplastic gingivitis and aphthous stomatitis, with aphthous stomatitis and pyostomatitis vegetans most commonly seen in ulcerative colitis. The aim of this study was to examine the attitudes and habits regarding oral health in patients with inflammatory bowel disease. Subjects and methods:A total of 76 participants participated in this cross-sectional survey, of which 42 had Crohn's disease and 34 had ulcerative colitis. The study was conducted at the Department of Gastroenterology and Hepatology, University Hospital of Split, and the Department of Pathophysiology during periods from December 2017 to May 2018. Subjects completed a specialized questionnaire consisting of 17 questions divided into 3 main groups, covering general data and patient habits, characteristics and subjective impression of the disease, and oral health habits. Results: The majority of patients (38.2% ulcerative colitis and 40.5% Crohn's disease) visit doctors of dental medicine only when needed, most often because they do not see a reason for more frequent visits. More than half of patients (67,1%) brush their teeth two to three times a day, mostly for 1-3 minutes.The most common types of brush used by patients are medium hard (44.7%) and soft (36.8%), while most are changed every 3 months (44.7%). In the case of oral health problems, 27 subjects with ulcerative colitis (79.4%) and 38 with Crohn's disease (90.5%) consult a dentist. Conclusions:Patients with inflammatory bowel disease mostly did not go to preventive examinations with a doctor of dental medicine, and it is extremely important that additional efforts be made to raise awareness of this important aspect of the disease
