Additional prevalence data are needed from developing countries prior to substantially altering the 1993 ECC/WHO Classification of oral lesions associated with adult HIV infection. The workshop confirmed current oral disease diagnostic criteria.

Future oral epidemiology research efforts in Africa should focus on the potential role of OC as sentinel marker of HIV infection and disease progression, to improve detection and prevention of selected opportunistic illnesses.

In this sample of HIV-infected adults, we found that men were significantly more likely to have hairy leukoplakia than were women. The hairy leukoplakia-gender association merits further investigation, because it may be related to a gender difference in the mode of expression of Epstein-Barr virus.

The workshop considered five questions reviewing the identification of international oral health care needs of children and adults, and the management of oral diseases in resource-poor countries: (1) What is the role of the dental profession in the management of the HIV-infected individual? (2) Identifying health care needs-What are the epidemiology and disparities of HIV-associated oral lesions in children from different continents? (3) How effective is HIV treatment in controlling oral diseases? (4) Could we develop basic inexpensive oral and dental care protocols for economically deprived HIV-infected patients? and (5) What is the best method of arranging resources to meet the oral health care needs of people with HIV disease? The consensus of the workshop participants was that there is a need to re-target research efforts to non-established market economy countries and prioritize research in these regions to children with HIV disease. It will be important to assess commonalities and variations in oral health needs across geographical and cultural boundaries, and research efforts should be centralized in resource-poor countries to support multi-center longitudinal standardized studies. It is essential that oral health research be integrated into other health care research programs, to make these research priorities and public health initiatives feasible.

This finding suggests that individuals with PHI who have oral lesions may be more likely to transmit HIV because of their higher viral load.
