Xeroderma pigmentosum: a case report.

This paper presents a case study of a child with xeroderma pigmentosum (XP). The disease results in sensitivity to UV radiation as a result of reduced activity in a defective enzyme responsible for DNA repair. Affected individuals have a variety of clinical symptoms, which may include problems of the skin and oral mucosa, ocular manifestations, and neurologic impairment. A number of precautions must be taken when treating these patients, which include proper shielding from damaging light and the selection of suitable dental materials. The necessary measures required when treating patients with XP are reviewed in this report.
