BackgroundIncreased incidence of periodontal disease is described in adult patients with inflammatory bowel disease (IBD), implicating similarities in gut immunopathogenesis and periodontitis.AimEvaluation of periodontal status and treatment needs of children with IBD in remission, according to disease phenotype, sex, age, and oral hygiene status, and compare them to age‐matched healthy population of a dental practice.MethodsFifty‐five children with IBD (mean age 12.27 ± 3.67 years) and 55 matched healthy controls of a dental practice (mean age 12.21 ± 3.96 years) were assessed with the simplified gingival index (GI‐S) and the plaque control record (PCR) index and the community periodontal index of treatment needs (CPITNs). A dental questionnaire on therapy, oral hygiene, gum bleeding, and dental attendance was completed by participants.ResultsChildren with IBD in remission had higher gingival inflammation and periodontal treatment needs compared to controls. In patients with IBD, the CPITN was higher in older compared to younger children (59.37% vs. 47.83%) and in boys compared to girls (65% vs. 46.67%). Among controls, CPITN was also higher in older children (21.88% vs. 4.34%) and in boys (16% vs. 13.33%).ConclusionOlder children and boys with IBD have more periodontal treatment needs, compared to controls, despite similar oral hygiene.
