Nowadays, necrotizing periodontal diseases have a low prevalence; however, a better understanding of the etiopathogenesis of these diseases is necessary for determining more adequate preventive and therapeutic strategies. From a pool of 1,232 HIV-infected patients, 15 presented with necrotizing periodontal diseases, which were evaluated by full-mouth periodontal clinical measurements. Subgingival biofilm samples were collected from necrotizing lesions of six of these individuals. The presence and levels of 47 bacterial species were determined by checkerboard DNA-DNA hybridization. All 15 patients (10 had severe immunodeficiency) had been infected sexually. Thirteen patients were taking antiretroviral medication (66.7% undergoing highly active antiretroviral therapy). Regarding necrotizing periodontal diseases, necrotizing ulcerative gingivitis (60%) was more prevalent than necrotizing ulcerative periodontitis (40%). The frequency of supragingival biofilm and bleeding on probing rang...
Factors Associated with Periodontitis in Patients with and without HIV
International Journal of Dentistry
Purpose. The aim of this study was to compare clinical periodontal conditions in HIV-positive people on HAART with an HIV-negative group, in addition to investigating factors associated with periodontitis in the entire sample. Methods. This was a cross-sectional study. Data were collected by oral clinical examination for the diagnosis of periodontitis, review of medical records, and application of a questionnaire containing personal data, deleterious habits, and oral hygiene habits for the other variables. The results were analyzed by Pearson’s χ2 test and Student’s t-test. A logistic regression model was constructed for the multivariate analysis and periodontitis was defined as a dependent variable. The analysis was performed on the entire sample (HIV+ and HIV−) and also on the group consisting of only people living with HIV. Results. Individuals older than 43 years old and with HIV were more likely to develop moderate and severe periodontitis (47.80 and 4.84 times, respectively). ...
