Arch Dermatol. 1992;128(7):901-902. doi:10.1001/archderm.1992.01680170027001

Investigation of the patients of a Florida dentist with acquired immunodeficiency syndrome (AIDS) concluded that human immunodeficiency virus (HIV) was transmitted to five (0.5%) of approximately 1100 patients who were evaluated.1-3 Although the precise events resulting in transmission of HIV to these patients are not known, the findings of the investigation support direct dentist-to-patient transmission, rather than a patient-to-patient route. This report summarizes information from other published studies of patients who were treated by HIV-infected health-care workers (HCWs),4-10 as well as from completed and ongoing unpublished investigations that have been reported to CDC.

In addition to the patients in the Florida dental practice, as of May 13, 1992, CDC was aware of HIV test results for 15 795 patients who were treated by 32 HIV-infected HCWs. The total number of patients treated by these HCWs and the number of patients who underwent invasive procedures are not known. No
