HIV infection affects 36.9 million people globally, and vitamin D deficiency is a global public health concern for HIV patients. Approximately 70 %–80 % of HIV-infected patients have vitamin D deficiency. The deficiency is associated with many pathologies such as immune disorders, infectious diseases, chronic inflammation, oral diseases, as well as the fast progression of HIV. The causes of vitamin D deficiency in HIV infections include HIV itself, traditional factors such as less sun exposure, mal-absorption, hypercholesterolemia, seasonal variation, poor nutrition as well as some HAART drugs like efavirenz. Vitamin D has an immunomodulatory, anti-inflammatory, and anti-proliferative function. In the oral cavity, it plays a significant role in preventing oral infections such as periodontal and gum diseases, dental caries, and oral candidiasis. The consequences of vitamin D deficiency are bone resorption, increased productions of pro-inflammatory cytokines, T-lymphocytes, increased T-helper-1 functions, and decreased T-helper-2 functions. Consequently, this leads to increased infections, chronic inflammation, and the occurrence of oral diseases such as oral candidiasis, periodontal and gum diseases, and dental caries. The majority of these oral diseases are encountered in HIV patients. Vitamin D deficiency is significantly found in HIV patients. There is a lack of studies that directly link vitamin D to most oral diseases in HIV patients; however, the role of vitamin D in immunoregulation, prevention of oral diseases, and HIV infection is substantiated.
