Periodontal diseases in HIV-infected patients

Abstract Periodontal diseases may be the first clinical sign of human immunodeficiency virus (HIV)-infection. Since the immunosuppression and subsequent susceptibility may alter the responses of the oral tissues as well as the microflora, both periodontal treatment and result of therapy may be modified. The periodontal diseases in HIV-seropositive patients include common as well as less conventional forms of gingivitis and periodontitis, and bacteria, mycotic and viral infections are seen. Neoplasias may also involve the periodontium; most common are Kaposi's sarcoma and non-Hodgkin's lymphoma. Recent studies of unselected groups of patients indicate that periodontal health in at least some groups of HIV-seropositive patients is better than previously reported.
