持续低剂量的二氧化 (ClO2) 有效地消毒牙科单位的水线,可持续地减少微生物负载. 定期高剂量的ClO2治疗对于去除固的生物膜是有效的,确保更好的牙卫生.
科学领域:
- 牙卫生 牙卫生
- 微生物学 微生物学
- 传染病控制中的传染病控制
背景情况:
- 牙科椅子单元 (DCU) 的水线容易受到微生物污染,造成感染风险.
- 定期消毒对于患者和牙科人员的安全至关重要.
研究的目的:
- 评估二氧化 (ClO2) 冲洗方案,以减少DCU中的微生物和生物膜.
- 确定最佳的ClO2度和冲洗频率,以有效消毒水道.
主要方法:
- 测试了具有不同ClO2度和冲洗频率的自动化协议.
- 微生物负载使用流量细胞计和亚格培养来评估.
- 评估了生物膜去除功效.
主要成果:
- 持续低剂量ClO2 (1.2 mg/L) 实现了可持续的微生物减少 (高达2.51 log10).
- 单次高剂量冲击消毒 (22.7 mg/L) 仅提供过渡性减少.
- ClO2有效地去除了生物膜,但其在停滞期间的耗尽需要持续应用.
结论:
- 常规低剂量ClO2的应用是推用于DCU水线的可持续消毒.
- 定期高度冲击消毒可以用于生物膜去除,特别是P. aeruginosa生物膜.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
