Various authors have reported the presence of Legionella spp. in dental unit waterlines with prevalence rates reaching, in some cases, 69.7% In order to evaluate the association between occupational exposure to Legionella and risk of infection, anti-Legionella spp. antibodies were measured in 88 dental assistants, 44 of which exposed and 44 not exposed to dental environments. Antibody levels > 1:128 were considered positive for infection. Relative risk was found to be 3.5 (p<0.01). These results confirm the hypothesis that workers in dental health-care settings are at occupational risk for Legionella infection. It is essential, therefore, that surveillance of microbiological quality of dental waterlines be implemented and appropriate disinfection procedures performed where necessary.
多位作者报告在牙科设备水线中存在嗜肺军团菌属，在某些情况下患病率高达69.7%。为了评估职业性接触嗜肺军团菌与感染风险之间的关联，对88名牙科助手进行了抗嗜肺军团菌属抗体检测，其中44人接触牙科环境，44人未接触。抗体水平>1:128被视为感染阳性。相对风险为3.5（p<0.01）。这些结果证实了牙科保健环境中的工作人员存在嗜肺军团菌感染职业风险这一假设。因此，对牙科水线的微生物质量进行监测并在必要时执行适当的消毒程序至关重要。
