Abstract
HIV/Aids patients present a change of microbiota associated with host immunodeficiency. Photodynamic therapy (PDT) showed as a promising and viable alternative in reducing microbiota. Present study evaluate effectiveness of photodynamic therapy in periodontal disease of AIDS patients with highly activity antiretroviral therapy (HAART) failure, measuring the clinical periodontal parameters and periodontal microbiota. Twelve patients with HARRT resistance (R group) divided into two groups (control and PDT) and 12 patients with no HAART resistance (NR group) divided into two groups (control and PDT). The results show the difference in baseline of CD4 cells count, NR group 640.0 ± 176.2 cells/mm3 R group and 333.3 ± 205.8 cells / mm3 (p<0.05), and in 8.3% detectable viral load in NR group and 75% detectable (p <0.001) in R group. As clinical periodontal parameters (PD and CAL), PDT was more effective than the control group only in the NR group (p <0.05%), moreover, there was no difference in the evaluation of clinical periodontal parameters between the both R groups (p>0.05%). Microbiological evaluation in R group presents a general reduction in the Aa at 3 and 6 months. Furthermore, demonstrated a reduction of Pg in all groups at 6 months and in R group at 3 months. The impact assessment of photodynamic therapy in patients with different levels of immunosuppression determined that the combination of mechanical periodontal treatment with photodynamic therapy in patients with HAART failure did not cause additional benefits. Therefore, PDT in this study could not been indicated in HAART resistance patients.
