Division of Pediatrics, Ogaki Municipal Hospital The Rubinstein-Taybi syndrome, originally described by Rubinstein and Taybi in 1963, is characterized by broad thumbs and toes, CHARACTERISTIC FACIAL FEATURES, mental retardation, short stature and various malformations. The syndrome has included some abnomalities in the dental area.
The case of a four year old boy, who was diagnosed as the Rubinstein-Taybi syndrome at the Pediatric Clinic, Ogaki Municipal Hospital, was refered to the Department of Pedodontics, Asahi Univ. Hospital for a dental examination. This patient was found to have typical symptoms associated with the Rubinstein-Taybi syndrome.
The dental findings, pertinent to this patient, were delayed eruption, retarded change in dentition, micrognathia, disfiguring of the dental arch and bifid uvula. A V-shaped dental arch in both jaws, cross-bite, as well as crowding of the anterior teeth were also noticed, but neither caries nor gingivitis were observed. The palate was generally shallow, but there was an inverted V-shaped hollow along the median palatine suture. Radiographic examinations showed enlarged dorsum sella, retarded bone calcification, and an enlarged distal phalanx of the thumb bone.
