生物膜在牙科综合治疗台水管线上迅速形成。生物膜中的大多数生物体是无害的环境物种，但一些牙科综合治疗台可能含有机会性呼吸道病原体。本文介绍了一种风险评估方法，分析生物膜生物污染牙科综合治疗台水管对牙科团队和患者呼吸健康的危害。呼吸道病原体军团菌、分枝杆菌和假单胞菌对健康的风险很低。然而，为了满足水的法规，并符合健康和安全立法，牙医应制定感染控制措施，以保持牙科综合治疗台水的标准低于每毫升200个菌落形成单位的好氧细菌。
Biofilms form rapidly on dental unit waterlines. The majority of the organisms in the biofilm are harmless environmental species, but some dental units may harbour opportunistic respiratory pathogens. This paper describes a risk assessment approach to analysing the hazard from biofilm organisms contaminating dental unit waterlines on the respiratory health of both the dental team and patients. The health risk from the respiratory pathogens Legionella spp, Mycobacterium spp and Pseudomonads was found to be low. Nevertheless, in order to satisfy water regulations and comply with health and safety legislation dentists should institute infection-control measures to maintain the dental unit water at the standard of less than 200 colony-forming units per ml of aerobic bacteria.
