Larsen syndrome: a review of the literature and case report.

Larsen syndrome is a rare genetic disorder characterized by multiple dislocations of the large joints and characteristic craniofacial abnormalities. It exists in both a severe autosomal recessive form and a mild autosomal dominant variety. To date, only three authors have reported oral findings for this syndrome. This paper describes an 8-year-old Chinese boy with Larsen syndrome who had advanced periodontitis. The need for periodontal therapy and regular monitoring of such patients has been highlighted.
