The purpose of this study was to survey, serologically, the exposure history of USAF dental laboratory technicians to hepatitis B virus (HBV), and to compare the incidence to that found in the general military population. Blood samples from 145 technicians, with an average age of 26.9 (S.D. = 6.9) in four locations in the USA and Europe, were tested for the presence of HBV core antibody using a standard enzyme immunoassay (EIA) procedure. These results were compared against 397 military members in non-medical fields of equivalent age and rank. The binomially distributed data was converted to a z distribution and a statistically significant difference was found in a comparison of the probability of detecting anti-HBc in each population (P = 0.034) where the incidence among the technicians was 2.7% and the military population 0.76%. Use of a "barrier system" in the laboratory, and vaccinations, could prevent any increase in this incidence from an occupational source.
本研究的目的是通过血清学方法调查美国空军牙科实验室技术人员感染乙型肝炎病毒（HBV）的暴露史，并将其发病率与普通军人的发病率进行比较。在美国和欧洲四个地点采集了145名技术人员的血样，他们的平均年龄为26.9岁（标准差=6.9），采用标准酶免疫测定（EIA）程序检测血样中是否存在HBV核心抗体。将这些结果与年龄和军衔相当的397名非医学领域军人的结果进行比较。将二项分布数据转换为z分布，发现在比较每个人群中检测到抗-HBc的概率时存在统计学显著差异（P = 0.034），其中技术人员中的发病率为2.7%，军人群体中的发病率为0.76%。在实验室中使用“屏障系统”和接种疫苗，可以防止职业性来源导致的发病率上升。
