每两周或每周一次使用过氧化 (H2O2) 的冲击治疗有效控制了牙科单位水线 (DUWL) 的污染. 更频繁的H2O2治疗在这个短期研究中显示出更好的结果.
科学领域:
- 牙卫生和感染控制.
- 微生物学 微生物学
- 材料科学是一种材料科学.
背景情况:
- 牙科单位的水线 (DUWL) 容易受到微生物污染.
- 在DUWLs中形成生物膜会造成严重的感染风险.
- 有效的消毒方案对于患者的安全至关重要.
研究的目的:
- 为了比较不同的过氧化 (H2O2) 冲击处理频率对DUWL消毒的有效性.
- 为了确定控制DUWL污染的最佳消毒计划.
主要方法:
- 三组牙科单位接受了连续的0.0141%H2治疗.
- 用1.41%的H2O2进行冲击治疗,每三周一次 (A组),每两周一次 (B组) 或每周一次 (C组).
- 在6周内评估了细菌数量和生物膜形态.
主要成果:
- 所有组在生物膜去除套 (BRS®) 治疗后显示出初始细菌数量减少.
- B组 (每两周一次) 和C组 (每周一次) 实现了100%的符合100CFU/mL值.
- 组A (每三周一次) 显示可见生物膜的遵守率 (68.42%) 显着较低.
结论:
- 连续0.0141%H2O2与每两周或每周1.41%H2O2的冲击治疗有效控制了短期的DUWL污染.
- 更频繁的冲击治疗 (每两周/每周一次) 比较不频繁的 (每三周一次) 更有效.
- 建议对更大的样本大小和更长的持续时间进行进一步的研究,以评估长期疗效.

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...
