Sera were collected from 50 practising dental surgeons and 50 control subjects matched for age (+/- 1 year) and sex. Each participant completed a questionnaire including personal details and, in the case of dentists, information relating to protective work-wear and other cross-infection control measures employed within the surgery. The sera were examined by complement fixation tests for antibodies to influenza A, influenza B, respiratory syncytial virus and adenovirus. The dental group had a significantly elevated prevalence of antibodies to influenza A (P = 0.01), influenza B (P < 0.001) and respiratory syncytial virus (P = 0.001) compared with the controls. More dentists than controls also carried antibodies to adenoviruses, although this difference did not attain statistical significance. Wearing of masks or eye protection did not markedly reduce infection with these viruses among the dentists. It is concluded that dentists are at occupational risk of infection with respiratory tract viruses, and that mask- or spectacle-wearing afford little protection.
从50名执业牙医和50名年龄（±1岁）及性别匹配的对照受试者中采集血清。每位参与者都填写了一份问卷，包括个人详细信息，对于牙医而言，还包括与防护工作服以及手术室内采用的其他交叉感染控制措施相关的信息。通过补体结合试验检测血清中针对甲型流感病毒、乙型流感病毒、呼吸道合胞病毒和腺病毒的抗体。与对照组相比，牙医组中针对甲型流感病毒（P = 0.01）、乙型流感病毒（P < 0.001）和呼吸道合胞病毒（P = 0.001）的抗体流行率显著升高。携带腺病毒抗体的牙医也比对照组多，尽管这种差异未达到统计学显著性。在牙医中，佩戴口罩或眼部防护用品并未显著降低这些病毒的感染率。得出的结论是，牙医面临呼吸道病毒感染的职业风险，并且佩戴口罩或眼镜几乎没有防护作用。
