A seroepidemiological survey of the prevalence of hepatitis B virus (HBV) markers was conducted in a group of 693 dental personnel in Singapore where HBV infection is endemic. The overall prevalence of HBsAg (4.5%) and anti-HBc (29%) was no higher than that in the general population. However, dentists had a significantly higher HBsAg prevalence (11.4%) compared with that in the general population (4.2%) (P less than 0.01) and of other categories of dental personnel (3.1%) (P less than 0.001). Similarly, the anti-HBc prevalence of the dentists (45.6%) was significantly higher than that of the general population (29.7%) (P less than 0.01) and of other categories of dental personnel (25.7%) (P less than 0.0001). It appears that dentists in the endemic area have a definite occupational risk of acquiring HBV infection.
在新加坡乙肝病毒（HBV）感染呈地方性流行，对693名牙科工作人员进行了一项关于HBV标志物流行情况的血清流行病学调查。HBsAg总体流行率（4.5%）和抗-HBc总体流行率（29%）并不高于普通人群。然而，与普通人群（4.2%）相比，牙医的HBsAg流行率显著更高（11.4%）（P<0.01），与其他类别的牙科工作人员（3.1%）相比也显著更高（P<0.001）。同样，牙医的抗-HBc流行率（45.6%）显著高于普通人群（29.7%）（P<0.01），与其他类别的牙科工作人员（25.7%）相比也显著更高（P<0.0001）。看来在该地方性流行地区，牙医有明确的职业感染HBV的风险。
