Disinfection and Bacterial Contamination of Dental Unit Waterlines in Nanjing’s Healthcare Institutions
Year: 2025
Type: article
Abstract: This study aims to analyze the current status of dental unit waterline (DUWL) disinfection and bacterial contamination in stomatology departments in Nanjing’s healthcare institutions. Targeted stomatology departments, a specialized investigation was conducted focusing on DUWL disinfection methods, disinfection frequency, water quality monitoring, and bacterial contamination, systematically analyzing current disinfection management deficiencies and potential risks of bacterial contamination. The investigation revealed significant variations in the implementation effectiveness of DUWL disinfection measures among stomatology departments in Nanjing’s dental institutions. Some institutions exhibited deficiencies such as singular disinfection methods, insufficient frequency, and weak water quality monitoring. The bacterial contamination levels exceeded relevant standards, posing an impact on treatment safety. This study suggests to optimize disinfection procedures and strengthen monitoring mechanisms in accordance with industry standards to reduce contamination levels and ensure the safety of dental treatment water.
