Craniofacial and dental features in kabuki syndrome patients.

Objective : To describe oral manifestations in Brazilian individuals with Kabuki syndrome, a multiple congenital anomaly/mental retardation syndrome. Study Design : A total of 16 Kabuki syndrome individuals, aged between 8 to 24 years and of both sexes, were referred by the Department of Clinical Genetics for oral treatment and follow-up to the Oral Care Center for Inherited Diseases, University Hospital of Brasília, Brasília, Brazil. Each individual underwent complete physical examination, as well as intraoral and radiographic examinations. Results : Craniofacial and dental alterations were observed in all Kabuki syndrome patients examined. In addition, atypical shape of the molars' crowns, occlusal convergence of the premolars' crowns, and root dilaceration were also observed. Enamel diffuse opacities were observed in permanent dentition (n  =  10). Conclusion : A great clinical heterogeneity was observed in Kabuki syndrome individuals in line with previous studies in the literature. Further clinical and molecular studies are necessary in order to better understand the presence of dental anomalies in this syndrome.
