Extensive dental caries in a HIV positive adult patient on ART; case report and literature review.

BACKGROUND: The estimated number of people living with human immunodeficiency virus (HIV) (PLHIV) in Uganda is 1.5 million (7.3%). As of June 2016, 60% (898,197) of PLHIV were enrolled and receiving antiretroviral therapy (ART). In scientific literature, the effect of HIV and ART on dental caries remains equivocal. At the Prosthetics Clinic of the Department of Dentistry, Makerere University College of Health Sciences, we have seen a number of PLHIV who require replacement of missing teeth with partial or complete dentures as a result of extensive caries. Here we report a case of an HIV positive female patient with extensive dental caries resulting in complete edentulous jaws, associated with psychological stress and stigmatization. CASE PRESENTATION: A 52-year-old patient, HIV positive for fourteen (14) years and receiving antiretroviral therapy (ART) for the last four years wanted to replace her missing teeth for effective feeding and cosmetic reasons. A diagnosis of partially edentulous maxillary and mandibular arches, cervical caries of tooth # 12, 15, 25, 34 and retained roots of tooth # 11, 13, 22 and 35 was made. Following oral health education and mouth preparation, this patient received a set of removable acrylic full upper and lower dentures. CONCLUSION: This case may represent the long-term effects of HIV and ART on oral health status especially tooth surfaces in some PLHIV. Further evaluation is required to ascertain if this was an isolated case or it is a common finding among HIV positive adult patients receiving long-term ART in sub-Saharan Africa. Information emerging from these studies would establish the magnitude of dental caries among PLHIV and guide the development of appropriate oral health care guidelines in the management of people living with HIV.
