综合干预措施对口腔综合治疗台水路污染控制效果的影响

Objective The effect of comprehensive intervention measures on the control of waterway pollution in dental treatment unit systems. Methods Microbial monitoring was conducted on the outlet water samples from 70 dental chairs across various clinical departments in our hospital from January 2025 to June 2025. The samples were collected after a 3-minute pre-operation pipeline flushing, a 20～30 second post-treatment rinse, and weekly cleaning with multi-enzyme solution. The total bacterial colony count served as the evaluation index, with a standard of ≤100 CFU/mL for compliance, in accordance with the “Sanitary Standard for Drinking Water”. Results A total of 120 valid samples were collected, with an overall compliance rate of 96.66%. Of these samples, 4 were found to have bacterial counts exceeding the standard(>100 CFU/mL), and the maximum colony count reached 570 CFU/mL. Compared with the compliance rate of 70.34% before the intervention, the compliance rate after the intervention increased by 26.32%. Conclusion This study confirms that the comprehensive intervention measures employed can effectively control bacterial contamination in DUWLs below safe levels, maintaining a high water quality compliance rate of 96.66%. These measures are crucial for ensuring the safety of dental treatment water and preventing cross-infection. They are proven to be scientific, effective, and cost-efficient, which facilitates their clinical popularization and makes them a reliable strategy for improving the quality of infection control in dental departments and protecting the safety of both patients and medical staff.
