aim of this study was to determine the effects of long-term use of highly
active antiretroviral therapy (HAART) on oral health status of HIV-infected
subjects. Methods: Oral examination and measurement of saliva flow rate of
both unstimulated and wax-stimulated whole saliva were performed in
HIV-infected subjects with and without HAART, and in non-HIV individuals.
The following data were recorded; duration and risk of HIV infection, type
and duration of HAART, CD4 cell count, viral load, presence of orofacial
pain, oral dryness, oral burning sensation, oral lesions, cervical caries,
and periodontal pocket. Multiple logistic regression analysis was performed
to determine the effects of long-term use of HAART on oral health status of
HIV-infected subjects. Results: One hundred and fifty-seven HIV-infected
subjects - 99 on HAART (age range 23-57 years, mean 39 years) and 58 not on
HAART (age range 20-59 years, mean 34 years) - and 50 non-HIV controls (age
range 19-59 years, mean 36 years) were enrolled. The most common HAART
regimen was 2 NRTI + 2 NNRTI. HIV-infected subjects without HAART showed
greater risks of having orofacial pain, oral dryness, oral lesions, and
periodontal pockets than those with short-term HAART (P < 0.01). The
subjects with long-term HAART were found to have a greater risk of having
oral lesions than those with short-term HAART (P < 0.05). The unstimulated
and stimulated salivary flow rates of the subjects with HAART were
significantly lower than in those without HAART (P < 0.05). Conclusion: We
conclude that long-term HAART has adverse effects on oral health status of
HIV-infected subjects. |
