Correlation between dental symptoms and functional and clinical manifestations of Crohn's disease and ulcerative colitis

Objective. To analyze the correlation between dental symptoms and clinical and functional manifestations of Crohn's disease (CD) and ulcerative colitis (UC). Materials and methods. A prospective, observational, longitudinal clinical study of 70 patients with verified inflammatory bowel diseases, i.e. Crohn's disease and ulcerative colitis, has been performed. For an in-depth assessment of the oral mucosa (OM) and red lip border (RLB) condition in patients with these systemic diseases, a complete dental examination has been carried out. The validated questionnaire "7´7" was used to objectify the symptoms of functional gastric dyspepsia. Results. In patients with the main clinical manifestations of the gastrointestinal tract impairments in CD and UC, extraintestinal dental manifestations in the form of meteorological cheilitis (16 and 9, respectively; p = 0.081), glossitis (15 and 11, respectively; p = 0.323), onset of recurrent aphthous stomatitis (17 and 11; p = 0.144), chronic mechanical trauma of oral mucosa (14 and 11; p = 0.455), and the presence of scalloped tongue (28 and 21, p = 0.068) were diagnosed. At the same time, the incidence of associated pathologies of OM and RLB was significantly higher in patients with CD (p0.05) than in patients with UC. Clinical examination of patients revealed predominance of flatulence symptoms in patients with CD and UC in 74.3 and 77.1 % of cases, respectively (р = 0.771). Patients with CD prevailed in the number of dyspeptic disorders and their variability but statistically significant differences were determined only for the symptom 'abdominal pain decreasing after bowel emptying'. The correlation between the frequency of dyspeptic disorders in patients and characteristic changes in the clinical state of RLB and OM was revealed. For the CD and UC groups Chuprov conjugacy coefficients were statistically significant (ChC=0.36, ChC=0.28 respectively). In patients with CD clinically apparent changes in the RLB and OM associated with various dyspeptic disorders were manifested more often than in patients with UC. Conclusion. The conducted study has shown that in patients with CD and UC there is a correlation between the frequency and severity of the main functional and clinical symptoms/syndromes (in the form of edema, hyperemia, pitting edema of the ОМ (in fact) and the RLB) and dyspeptic disorders, this correlation being stronger in Crohn's disease (p = 0.031 vs p = 0.046).
