A number of studies have demonstrated the negative impact on oral health of HIV infection (16–20). Approximately 40–50% of people who are HIV-positive have oral disease caused by fungal, bacterial or viral infections that often occur early in the course of the disease. Oral lesions strongly associated with HIV infection are pseudo-membranous oral candidiasis, oral hairy leukoplakia, HIV gingivitis and periodontitis, Kaposi sarcoma and non-Hodgkin lymphoma. Dry mouth as a result of decreased salivary flow rate may not only increase the risk of dental caries but also have a negative impact on quality of life because it leads to difficulty in chewing, swallowing and tasting food. The need for oral health care including immediate care and referral, treatment of manifest oral disease, prevention of problems and health promotion is particularly great among the underserved, disadvantaged population groups of developing countries, including people infected with HIV (17, 19).
