RESUMO
PURPOSE: The purposes of this study were to: (1) quantify and identify Candida species (spp.) in the dental plaque of children infected with the human immunodeficiency virus (HIV) and compare with noninfected children; and (2) determine the association of Candida spp. with the presence of caries. METHODS: Seventy HIV-infected and 55 non-HIV-infected three- to 12-year-old children were examined to determine caries prevalence. After a visual inspection, supragingival plaque was collected from the cervical region using standard dental curettes. The material was transferred to microtubes and submitted for analysis to identify and quantify the presence of Candida spp. RESULTS: Candida spp. were more prevalent in the HIV-infected group (72.9 percent) than in the control group (20 percent), and the most prevalent specie was Candida albicans. Caries was found in 72.9 percent of the HIV-infected group and in 58.2 percent of the control group, but a significant difference was only found in the presence of active white spot lesions between the groups. CONCLUSIONS: The dental plaque of HIV-infected children was colonized by Candida species to a much greater extent than that of non-HIV-infected children, and this colonization was significantly associated with the prevalence of early carious lesions in enamel.
