A survey of the prevalence of HBV infection in 215 mentallyretarded patients in three institutions in Okinawa was conducted. The serum HBs antigen positive patients were given oral care treatment in order to determine the correlation with occult blood in saliva and the rate of gingival bleeding and HBs antigen in saliva. Furthermore, the oral care treatment was given to show whether or not the oral care is effective to prevent HBV infection in institutions. The following results were obtained. 1. It has been shown that HBs antigen positive rate in the mentally retarded patients in three institutions was 11.2% and HBc antibody positive rate was 54.4%. Both results were considerably higher than any other area in Japan. 2. HBs antigen in saliva was detected among 15 cases out of 24 HBV carriers (62.5%). The longer the oral care was given in HBV carriers, the lesser the positive rate of HBs antigen in saliva. Twelve months later, no HBs antigen in saliva was detected. 3. The rate of HBs antigen detection in saliva was observed to be significantly higher in the positive occult blood group in comparison with the negative occult blood group. 4. The rate of the prevalence of HBV infection without oral care during the five-year period between 1984 and 1989 was 10.8%, however, the rate of the prevalence of HBV infection with oral care was 0% between 1989 and 1996,showing that no patient was found to be newly infected by HBV. The results of this study indicate that a through oral care for HBV carriers in the institutions for the mentally retarded would decrease the rate of gingival bleeding and the positive rate of occult blood in saliva and vanish HBs antigen in saliva eventually. Thus, it can be concluded that the oral care treatment is one of the effective means to prevent HBV infection in mentally retarded patients in these institutions.
