Abstract: Associations between body dysmorphic disorder (BDD) with the dental health component of the index of orthodontic treatment need (IOTN-DHC) and other BDD risk factors in orthodontic patients: A preliminary study Objective: Body dysmorphic disorder (BDD) is a form of obsessive-compulsive disorder that may be negatively associated with the self-image.It might be associated with orthodontic treatment demand and outcome, and therefore is important.Thus, this study was conducted.Methods: The Yale-Brown Obsessive-Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS) questionnaire was used in 699 orthodontic patients above 12 years of age (222 males, 477 females), at seven clinics in two cities (2020-2021).BDD diagnosis and severity were calculated based on the first 3 items and all 12 items of the questionnaire.The dental health component of the index of orthodontic treatment need (IOTN-DHC) was assessed by orthodontists.Multivariable and bivariable statistical analyses were performed on ordinal and dichotomized BDD diagnoses to assess potentially associated factors (IOTN-DHC, age, sex, marital status, education level, and previous orthodontic consultation) (α = 0.05).Results: IOTN-DHC scores 1-5 were seen in 13.0%, 39.9%, 29.8%, 12.4%, and 4.9% of patients.Age/sex/ marital status/education were not associated with IOTN-DHC (p > 0.05).Based on 3-item questionnaire, 17.02% of patients had BDD (14.02% mild).Based on 12-item questionnaire, 2.86% had BDD.BDD was more prevalent or severer in females, married patients, patients with a previous history of orthodontic consultation, and patients with milder IOTN-DHCs (p < 0.05).Conclusions: IOTN-DHC was negatively/slightly associated with BDD in orthodontic patients.Being female and married may increase BDD risk.
