Lesch-Nyhan syndrome. A case report.
Lesch-Nyhan syndrome is a rare anomaly consisting of a deficiency in the production of hypoxanthine phosphoribosyltransferase that leads to the overproduction of purine and the accumulation of uric acid. Major manifestations include mental retardation and self-destructive behavior resulting in self-mutilation through biting and scratching. Because no medical treatment exists to alleviate the symptoms of self-mutilation, direct dental intervention is the only way these behaviors can be affected. A unique case of this type involving two male identical twins is reported.
