Abstract

Chairside decontamination. of files and reamers is attempted during root canal treatment. The purpose of this study was to evaluate some techniques for reducing the number of microorganisms of artificially contaminated endodontic files. Endodontic files were artificially contaminated with about 10,000 colony-forming units of either B. subtilis spores or S. mitis. The files containing the bacteria were then subjected to various decontamination procedures. Although sterilization was not achieved with any procedure, the bead sterilizer was found to be the most effective decontamination method tested. All gauze wipings showed reductions greater than 90 per cent. It was concluded that wiping with 2 by 2 inch gauze is a highly efficient and practical method of chairside decontamination

摘要

在根管治疗过程中尝试进行器械的椅旁消毒。本研究的目的是评估一些减少人工污染的牙髓锉微生物数量的技术。牙髓锉被枯草芽孢杆菌孢子或缓症链球菌的约10000个菌落形成单位人工污染。然后将含有细菌的器械进行各种消毒程序。尽管任何程序都未实现灭菌，但发现珠状消毒器是所测试的最有效的消毒方法。所有纱布擦拭均显示减少率大于90%。得出结论，用2×2英寸纱布擦拭是一种高效且实用的椅旁消毒方法。
