概括

缺少用于牙周内科仪器的标准化清洁协议. 手动,超声波和蒸汽杀菌清洗的组合是最有效的,但完全清除碎片仍然是一个挑战.

科学领域:

牙科仪器是指牙科仪器.
消毒和消毒的消毒和消毒.
牙周内科医院牙周内科医院牙周内科医院

背景情况:

牙周内仪器需要有效的消毒和灭菌,以确保患者的安全.
目前用于清洗- (NiTi) 旋转文件的协议缺乏标准化.
评估废物清除对于确保仪器安全和处理成功至关重要.

研究的目的:

量化评估不同清洁方案在从使用的NiTi旋转内牙文件中去除碎片的有效性.
为了比较单独蒸汽杀菌的有效性,超声波清洁加蒸汽杀菌,手动清洁加超声波清洁加蒸汽杀菌.
确定内牙科仪器的最佳清洁策略.

主要方法:

使用了48个Mtwo NiTi旋转仪器,分为四组.
协议包括:负控制 (新无菌),仅蒸汽杀菌,超声波清洗+蒸汽杀菌,手动清洗+超声波清洗+蒸汽杀菌.
扫描电子显微镜 (SEM) 和斐济软件被用于量化文件表面上的碎片.

主要成果:

负对照组 (新仪器) 的碎片最少,而单独的蒸汽杀菌显示了最多的碎片.
在手动+超声波+蒸汽杀菌和超声波+蒸汽杀菌组之间没有发现显著的碎片差异.
在对照组和仅蒸汽灭菌组中,从冠状部分到顶部部分观察到较高的碎片积累.

结论:

结合机械,化学和超声波方法的全面清洁方法对于从内牙仪器中去除碎片是优越的.
现有的清洁方案不足以完全清除碎片.
需要进一步的研究来规范协议,或考虑一次性使用的工具.

关键词:

Cleaning, Sterilization, and Disinfection

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
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...
