牙科综合治疗台水路微生物污染及防治

Abstract

Abstract: Dental unit waterline (DUWL) output water can be heavily contaminated with microorganisms. Since patients and dental staff are regularly exposed to water and aerosols generated from the dental unit, contaminated DUWL water is considered as an occupational hazard. The features of DUWL contamination, the causes of DUWL contamination and the control methods of DUWL contamination have been researched for many years. The article reviewed these issues.

Key words: dental unit waterline (DUWL), biofilm, infection control

CLC Number:

　R780.2
