The objectives of this cross-sectional study were to determine the frequency of HIV infection among dental patients attending the three dental facilities at Muhimbili Medical Centre (MMC) in Dar-es-Salaam, Tanzania, and to compare the dental treatment demands and needs of the patients found to be HIV-infected with those of their HIV-seronegative counterparts. The facilities were; the dental outpatient department (DOPD) clinic, the dental minor surgery department, and the dental ward. This study which was conducted between March and April, 1996 enrolled a total of 460 patients. The investigations involved detection of anti-HIV IgG antibodies in saliva, examination of oral and peri-oral tissues, and assessment of dental and periodontal status. The overall HIV frequency among the dental patients was 10.9 per cent. The frequencies of HIV infection among patients attending the dental OPD clinic, minor surgery, and those admitted in the dental ward were 9.4 per cent, 26.3 per cent, and 25.0 per cent, respectively. The dental treatment demands and needs of HIV-seropositive patients were not different from that of HIV-seronegative patients. The high frequency of HIV infection calls for institution of infection control measures in the dental clinics. However, such measures need to be tailored for the poor countries, with potentially high frequency of HIV infection and minimal resources, in order to make them relevant.
这项横断面研究的目的是确定在坦桑尼亚达累斯萨拉姆的穆希姆比利医疗中心（MMC）的三个牙科机构就诊的牙科患者中艾滋病毒感染的频率，并比较艾滋病毒检测呈阳性的患者与其艾滋病毒血清阴性的对应患者的牙科治疗需求。这些机构包括：牙科门诊部（DOPD）诊所、牙科小外科和牙科病房。这项于1996年3月至4月进行的研究共招募了460名患者。调查包括检测唾液中的抗艾滋病毒IgG抗体、检查口腔和口腔周围组织以及评估牙齿和牙周状况。牙科患者中艾滋病毒的总体感染率为10.9%。在牙科门诊部诊所、小外科就诊的患者以及牙科病房收治的患者中，艾滋病毒感染率分别为9.4%、26.3%和25.0%。艾滋病毒血清阳性患者的牙科治疗需求与艾滋病毒血清阴性患者并无不同。艾滋病毒感染的高频率要求在牙科诊所采取感染控制措施。然而，这些措施需要针对艾滋病毒感染频率可能很高且资源极少的贫穷国家进行调整，以便使其具有相关性。
