To characterize some epidemiologic characteristics of viral hepatitis among dentists, information was obtained with a mailed questionnaire from 434 dentists and 787 attorneys in Dade County, Florida. Dentists had a significantly higher incidence of hepatitis than did lawyers, 6.7% vs 2.4%, with the highest rate among oral surgeons (21%). The incidence of hepatitis B antigenemia among asymptomatic dentists was not significantly higher than that of volunteer blood donors. Twenty-two percent of dentists with hepatitis reported treating more than ten drug addicts per year, as compared with 10% of those dentists without hepatitis. No differences were noted between dentists with and without hepatitis in methods of sterilization, the wearing of gloves during procedures, or the use of disposable needles. The increased risk of hepatitis among dentists, however, may be related to the omission of adequate prophylatic measures, particularly when treating high-risk patients such as drug abusers.
为了描述牙医中病毒性肝炎的一些流行病学特征，通过邮寄问卷的方式从佛罗里达州戴德县的434名牙医和787名律师那里获取了信息。牙医患肝炎的发病率显著高于律师，分别为6.7%和2.4%，其中口腔外科医生的发病率最高（21%）。无症状牙医中乙肝抗原血症的发病率并不显著高于志愿献血者。患肝炎的牙医中有22%报告称每年治疗超过10名吸毒者，而未患肝炎的牙医这一比例为10%。在消毒方法、操作过程中戴手套情况或使用一次性针头方面，患肝炎和未患肝炎的牙医之间未发现差异。然而，牙医患肝炎风险增加可能与未采取足够的预防措施有关，尤其是在治疗吸毒者等高风险患者时。
