Oro-Facio-Dental Findings of Rubinstein-Taybi Syndrome as a Useful Diagnostic Feature

Abstract

Rubinstein-Taybi Syndrome (RTS) is a rare multiple congenital syndrome characterized by distinctive facial features, mental and growth retardation, broad thumbs and great toes. This case report describes the oro-dental manifestations, as well as, orthodontic evaluation of a 9-year-old male patient who had RTS. The remarkable oro-dental features were talon-like cingulum on maxillary central incisors, unerupted supernumerary teeth. Cone-beam computerized tomography was taken in order to identify his skeletal anomalies, bilateral cross-bite and a narrow maxilla were diagnosed. Dental treatments were completed under i.v sedation due to the patient's inability to cooperate during dental treatment. Perioparetive and postoperative courses were uneventful. Following dental treatments, orthodontic therapy was initiated with a fixed rapid maxillary expansion appliance.
