Rubinstein-Taybi syndrome or Broad Thumb-Hallux syndrome is a genetic disorder 
characterized by facial dysmorphism, growth retardation, and mental deficiency. 
A seven-year-old girl had come to the Department of Pedodontics, Istanbul 
Medipol University, Faculty of Dentistry, Turkey, with a complaint of caries and 
bleeding of gingivae. The patient was mentally retarded. Extraoral features 
revealed distinctive facial appearance with a broad fore head, hypertelorism, 
broad nasal bridge, and beaked nose. Intraoral features observed were talons 
cusps in the upper lateral incisors, carious teeth, and plaque accumulation. 
Since the patient was mentally retarded, the dental treatment was done under GA. 
The treatment plan and dental management of this patient are discussed in this 
case report.
