Oral and dental manifestations in Rubinstein-Taybi syndrome: report of a rare case.

Abstract

Rubinstein-Taybi syndrome, or broad thumb-hallux syndrome, is a well-defined rare congenital disorder characterised by postnatal growth deficiency, craniofacial dysmorphism, broad thumbs and great toes, and mental retardation (intellectual disability). Occurrence may be either sporadic or through autosomal dominant inheritance. Reports of Rubinstein-Taybi syndrome are scarce in the literature. This case report describes the oral and dentofacial findings of Rubinstein-Taybi syndrome affecting a 13-year-old Indian female, including the uncommon presence of talon cusps and an unerupted supernumerary tooth.
