In June 1991, practicing, research, and academic dentists attended a symposium on oral research and dental treatment in HIV infection at Guy's Hospital in London, England. Oral lesions in HIV infection were classified as strongly associated, probably associated, and possibly associated with HIV infection. A speaker stressed that those strongly associated with HIV infection should be of the most interest to general dental practitioners. Another speaker said that chronic erythematous candidiasis has emerged as an oral infection strongly associated with HIV infection in addition to pseudomembranous candidiasis. A dentist mentioned hairy leukoplakia as a new condition strongly associated with HIV infection. Other HIV associated periodontal disease included gingivitis, necrotizing gingivitis, and periodontitis. A speaker noted that AZT increases longevity of AIDS patients and the drugs dideoxyinosine and dideooxycytidine are being tested. Another dentist spoke about the issue of HIV infected dentists citing the example of the dentist in Florida who infected 5 patients. Other speakers addressed the cases and needs of asymptomatic HIV infected people. A survey of dentists showed that only 33% of dentists would provide dental care to HIV infected people and only 20% would if the patients had AIDS. A dentist addressed the problem of a lack of data on prevention and treatment of oral lesions since their etiology and pathogenesis were unknown. Other presentations focused on research on antibodies and DNA probes in reference to saliva and subgingival flora. The symposium revealed the ran ge and depth of research going on in British schools on oral manifestations of HIV infection.

Data from cross-sectional studies suggest that periodontitis in HIV-infected patients is a more destructive form of disease in contrast to the slowly progressing form of adult periodontitis in the general population. We studied prospectively over an 18-month period 30 HIV infected, but asymptomatic, patients and compared the rate of periodontal attachment loss with that of a healthy control group (n = 10) matched for age and plaque index. Every 6 months, each subject was assessed for their clinical status by a physician and CD4+ cell count determined. The proliferative response of peripheral blood lymphocytes was determined by in vitro cultures with PHA and Con A. The periodontal health status was assessed by scoring with plaque index (PI), gingival index (GI), and periodontal disease index (PDI). The control subjects were assessed for periodontal status only. Of the 30 HIV-positive patients whose data were analyzed 14 received Zidovudine (AZT) while the remaining 16 did not. There was no correlation between any clinical parameter measured and periodontal status as determined by PI or GI. However, a significant difference in the change of periodontal disease index (PDI) was observed between the HIV-infected and control groups (P = 0.005). We concluded that HIV-infected patients with pre-existing periodontitis tend to experience a greater rate of attachment loss over time compared with controls.
