Abstract

|
|
|
Noonan syndrome (NS) is a developmental disorder characterized by dysmorphic facial features in association with short stature, mental retardation and congenital heart disease. NS may be sporadic or inherited as an autosomal dominant or recessive trait. The children with NS usually have ocular hypertelorism, downslanting palpebral fissures, low-set ears and a webbed neck, chest deformity. In addition, oral features include micrognathia, high arched palate, dental malocclusion, dental anomalies and rarely, cleft palate. The phenotype of NS bears similarities to that of Turner syndrome. However, NS occurs in both males and females with a normal sex chromosome 46, XX and 46, XY constitution. This case presents the intermittent treatment of an 8-year-old girl who was referred from a local clinic for the extraction of supernumerary teeth and treatment of dental caries. The focus of this case report is the oral aspects on NS and particularities of the dental treatment in subjects affected by this genetic disease.
