Abstract
Identification of extra-digestive manifestations of inflammatory bowel disease (IBD) is essential. The oral cavity is a preferential site in which gingival enlargement may be one of these manifestations. We present, in this article, two original cases and a concept map that highlights the need for a close collaboration between the dental surgeon or oral specialist, the dermatologist, and the gastroenterologist. In the first case, the strictly local management of a systemic IBD oral complication, can relieve and answer the patient's complaint without modifying or disrupting the systemic treatment already implemented by the gastroenterologists. In the second case, the dental surgeon's diagnosis of gingival enlargement turns out to be the inaugural manifestation of Crohn's disease and allows early treatment of the intestinal pathology. These two cases illustrate the close link between the oral cavity and IBD. Knowledge and multidisciplinary management of these manifestations such as proposed in the concept map are essential for clinicians for the early diagnosis and the improvement of the oral and general quality of life of patients suffering from IBD.
