Psoriatic triad in a patient presenting with oligodontia.

Psoriasis is a common dermatological disease. It can occur at any age but usually develops between 15 and 35 years of age and may persist throughout a person's lifetime with periods of exacerbation and remission. The hyperproliferative state of the affected epidermis produces a turnover rate that is up to eight times greater than normal. Instead of being shed, the skin cells pile up, causing the visible lesions. Oral manifestations of psoriasis are rare clinical observations. Lesions have been reported on the lips, buccal mucosa, palate, gingiva, and floor of the mouth. We document a presentation of psoriasis showing a triad: skin lesions, arthritis, and oral manifestations (oligodontia being patient's chief concern). Dental rehabilitation done was in the form of partial dentures. This was done to address the immediate concern of the patient, that is, inability to chew properly. As put forth through this case report, a potential link between psoriasis and oligodontia has scope for further study.
