OBJECTIVE
This study aimed to evaluate the long-term efficacy of two disinfection methods for waterline systems in inactive dental chair units (DCUs).
METHODS
On-site sampling and quantitative bacterial analysis were conducted to compare the effectiveness of chlorine-based disinfectants and a combination of multi-enzymatic detergent with hypochlorous acid in controlling microbial contamination in waterline systems of inactive DCUs.
RESULTS
No statistically significant differences in disinfection efficacy were observed between the treatment and control groups immediately after disinfection or on the third day post-disinfection (p > 0.05). However, significant differences were observed on the fifth day and seventh day following disinfection (p < 0.001).
CONCLUSION
Both chlorine-based disinfectants and the combination of multi-enzymatic detergent with hypochlorous acid effectively controlled contamination in waterline systems for DCUs inactive for up to three days. For periods of inactivity exceeding five days, the combination of multi-enzymatic detergent with hypochlorous acid demonstrated superior efficacy by reducing biofilm adhesion over time.
目的
本研究旨在评估两种消毒方法对闲置牙科治疗椅（DCU）水路系统的长期效果。
方法
进行现场采样和定量细菌分析，以比较氯基消毒剂以及多酶洗涤剂与次氯酸组合在控制闲置DCU水路系统微生物污染方面的有效性。
结果
消毒后立即或消毒后第三天，治疗组和对照组之间在消毒效果上未观察到统计学显著差异（p>0.05）。然而，在消毒后的第五天和第七天观察到显著差异（p<0.001）。
结论
氯基消毒剂以及多酶洗涤剂与次氯酸的组合均有效控制了长达三天闲置的DCU水路系统中的污染。对于闲置超过五天的时间段，多酶洗涤剂与次氯酸的组合通过随着时间推移减少生物膜粘附而显示出卓越的效果。
