Dentists in the Philippines were surveyed for evidence of past hepatitis A and B virus infections. Of the 234 dentists examined, 201 (85.9 per cent) were found to have been infected by HA virus and 137 (58.5 per cent) had been infected by HB virus. The proportion with evidence of past HB virus infection increased as the years in dental practice increased. This increment with age was not found in the general population of the Philippines. It is considered that the incremental pattern could be attributed to the summation of risk during many years of providing dental treatment. Comparing the proportion of dentists with HBV antibodies (anti-HBs/c) in the Philippines, Japan, USA and Denmark, the Philippine dentists were found to be more frequently infected than dentists in the other countries. However, the increment in the proportion positive for HBV as the years in practice advanced was consistent with that found in Japan. The prevalence of post HA virus infection in Philippine dentists was higher than the proportion for dentists in Japan but in both countries it is probable that dentists are infected at the same rate as the general population.
对菲律宾的牙医进行了调查，以寻找过去感染甲型和乙型肝炎病毒的证据。在接受检查的234名牙医中，发现201人（85.9%）曾感染过甲型肝炎病毒，137人（58.5%）曾感染过乙型肝炎病毒。有过去感染乙型肝炎病毒证据的比例随着从事牙科工作年限的增加而上升。在菲律宾的普通人群中未发现这种随年龄增长的增加情况。据认为，这种递增模式可归因于多年提供牙科治疗过程中风险的累积。比较菲律宾、日本、美国和丹麦的牙医中乙型肝炎病毒抗体（抗-HBs/c）的比例，发现菲律宾牙医比其他国家的牙医感染更为频繁。然而，随着从业年限的增加，乙型肝炎病毒阳性比例的增加情况与日本的情况一致。菲律宾牙医中甲型肝炎病毒感染后的患病率高于日本牙医，但在这两个国家，牙医的感染率可能与普通人群相同。
