Abstract
Opportunistic infections are common in patients infected with human immunodeficiency virus (HIV) in acquired immunodeficiency syndrome. This case report demonstrates a clinical case of an individual with periodontitis, HIV/hepatitis C coinfection, and candidiasis, using different drugs and under irregular antiretroviral therapy. The combination of several local and systemic conditions highlights the importance of the case and the need for health professionals to know the management of these combined pathologies in the context of HIV infection. We can conclude that it is extremely important for dentists to be aware of periodontal diseases in HIV-infected patients, due to the pathogenic mechanisms associated with these pathologies.
