Forty samples of air with a mean sample volume of 104 liters were collected during the treatment of patients whose blood was positive for HBsAG: no samples contained HBsAG and occult blood. These findings suggest that, if environmentally mediated transmission of hepatitis B occurs in the dental operatory, it is more likely to occur through contact with contaminated surfaces than through the airborne route.
在对乙肝表面抗原（HBsAG）血液检测呈阳性的患者进行治疗期间，采集了40份空气样本，平均样本体积为104升：所有样本均未检测出乙肝表面抗原和潜血。这些研究结果表明，如果乙肝在牙科诊疗室通过环境介导传播，那么更有可能是通过接触受污染的表面，而非空气传播途径。
