Introduction: Antiretrovirals are used in order to prevent viral replication while maintaining CD4 + T lymphocytes stable and low viral load, thus the occurrence of opportunistic infections decreases with an improvement in the quality of life of HIV-infected individual. As is known, protease inhibitors and reverse transcriptase are also associated with risk of adverse effects and development of drug resistance, however, it remains unclear the effect of these therapies on oral microbiota. Objective: The aim of this study was to investigate, in biofilm supra and subgingival in HIV - positive patients with different periodontal and immunological conditions, the effect of HAART on microorganisms that may be associated with local or systemic opportunistic infections. Materials and methods: Data on health conditions, use or nonuse of antiretroviral and biofilm samples supra and subgingival of 118 HIV - positive patients of both sexes, divided into two groups (users and nonusers of HAART), were obtained. These samples were subjected to PCR for detection of microorganisms. Odds ratio calculations were performed to determine the relevance of inter - relations between different microorganisms and the significance of clinical and microbiological parameters were determined using multivariate logistic regression. Results: Mainly T. forsythia, C. rectus, A. israelli, Staphylococcus sp and CMV were found. T denticola, F nucleatum, mollicutis, A. israelli and Staphylococcus sp in subgingival biofilm showed significant correlation (p <0.05) with antiretrovirals groups. Only E. faecalis and P. aeruginosa were significant with higher incidence in no HAART users group. Conclusion: There were no significant differences in...
