Objective: To determine whether dentist-to-patient or patient-to-patient transmission of human immunodeficiency virus (HIV) occurred in the practice of a dentist who had the acquired immunodeficiency syndrome (AIDS). Design: Retrospective epidemiologic investigation supported by molecular virology studies. Setting: The practice of a dentist with AIDS in an area with a high AIDS prevalence. Participants: A dentist with AIDS, his former employees, and his former patients, including 28 patients with HIV infection. Measurements: Identification of potential risks for acquisition of HIV infection, genetic relatedness among HIV strains, and infection-control practices
