Rubinstein-Taybi syndrome is a multiple anomalies congenital disorder characterised by broad thumb and halluces, facial dysmorphism with mental and growth retardation. Oral features include small mouth, retro and micronagthic jaws, highly arched and narrow palate. Dental anomalies such as teeth with talon cusps and screwdriver shaped permanent incisors together with crowded teeth are common features in these patients. Although hyperdontia is said to be one of the features of this condition, nevertheless, presence of multiple supernumerary teeth has never been documented. This report highlighted a case of an eleven-year-old boy with Rubinstein-Taybi syndrome referred for unerupted permanent incisors who exhibited multiple supernumerary teeth radiographically.
