Dental findings and muscular-skeletal features in Schwartz-Jampel syndrome: case report of two affected siblings.

Schwartz-Jampel syndrome (SJS) is a rare, inherited disorder defined by myotonia, skeletal malformations, muscular stiffness, and growth retardation. The clinical signs and symptoms of SJS are seen in the maxillofacial region. The combination of skeletal and muscular abnormalities predisposes affected individuals to a number of primary and secondary orodental manifestations. Although several studies have discussed the clinical features of SJS from a medical perspective, few reports have addressed the oral findings or dental treatment in children and adolescents with the disorder. This article reviews the dental manifestations and impairments of Schwartz-Jampel syndrome. The case histories of two siblings diagnosed with this disorder are described as well as their dental care.
