Objectives:
This study estimates factors associated with the prevalence of HIV-associated periodontal diseases (HIV-P) and the severity and extent of periodontitis in HIV-infected adults from North Carolina (NC).
Methods:
Data are derived from a cross-sectional study of HIV-infected adults (total n = 326, dentate n = 316) treated at the University of North Carolina Hospitals. Outcomes were a diagnosis of HIV-P and measures of probing pocket depth (PPD), recession (REC), and clinical attachment level (CAL). Immunosuppression was measured by peripheral blood CD4+ cells/mm3.
Results:
In addition to persons with HIV (non-AIDS), this study included 10 percent of the AIDS cases in North Carolina. Median age was 37 years (range = 19-67); 78 percent were male and 60 percent were black. Sixty-two percent of persons had a probing pocket depth > or = 5 mm; 46% had recession > or = 3 mm, and 66 percent had attachment level > or = 5 mm in one or more sites. Cases of HIV-P (n = 15) were rare. Persons taking HIV-antiretroviral medication were one-fifth (OR = 0.20; 95% CI = 0.07, 0.63) as likely to have HIV-P as those not taking those medications, controlling for CD4+ cell counts.
Conclusions:
HIV-infected persons in this study group from North Carolina exhibited severe and extensive measures of adult periodontitis. A small proportion experienced a severe form of HIV-P, which was attenuated by antiretroviral therapy.
