Abstract:
Dental unit waterlines(DUWLs)often experience severe microbial contamination.Opportunistic patho-gens such as Pseudomonas aeruginosa and Legionella pneumophila present in DUWLs can enter patients' mouths through procedural water,increasing the risk of infection during dental procedures.In response to the current situ-ation of waterline contamination,this paper systematically reviews domestic and international guidelines,local standards,and industry requirements related to contamination control in DUWLs.It discusses five aspects were explored:incoming water quality control,tubing material,physical control measures,chemical disinfection,and microbial testing.The paper deeply analyzes and distills relevant strategies for waterline contamination con-trol measures,providing a reference for infection prevention and control in dental practice to ensure patient safety.
