    Abstract:
    OBJECTIVE:  To assess the prevalences and patterns of oral lesions occurring in human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). METHODS:  A cross-sectional study was conducted among 200 people living with HIV/AIDS (PlwHA) who regularly attended a counselling and treatment centre in Dar es Salaam, Tanzania. A questionnaire-guided interview and clinical oral assessment were used. Strict confidentiality and adherence to ethical codes were observed. RESULTS: The mean age of participants was 38.91 years (standard deviation: 10.424; mode: 35 years; median: 37.0 years; range: 15-76 years). Most participants (58.5%) were aware of predispositions towards the occurrence of oral lesions such as oral candidiasis (60.0%) in HIV/AIDS and most of these (72.0%) were aware that the lesions are treatable. Some participants reported occurrences of oral thrush (22.5%) and lip ulcerations (28.5%), although only 47.0% of these had sought medical advice. Examinations revealed that 29.0% of participants had at least one oral lesion associated with HIV/AIDS. Prevalences of the various types of lesion were: 11.5% for herpes simplex; 7.5% for oral candidiasis; 4.0% for oral hairy leukoplakia; 3.5% for Kaposi's sarcoma; 1.5% for dry mouth; 0.5% for angular cheilitis, and 0.5% for acute necrotising ulcerative gingivitis. Herpes simplex and Kaposi's sarcoma were more frequently observed in males (56.5% and 71.4%, respectively), whereas oral candidiasis and dry mouth were observed more often in females (86.7% and 66.7%, respectively) (χ(2) = 16.692, P = 0.016). CONCLUSIONS:   Prevalences of oral lesions associated with HIV/AIDS in PlwHA and using antiretroviral therapy are persistent, of moderate intensity and vary according to individual immune status. These patients' level of awareness about oral lesions was satisfactory, but formal medicodental lines of management were not prioritised. Contemporary protocol for the management of oral lesions should be understood and disseminated to the general public by dentists.
