摘要

本研究评估了牙科中用于去除杜仲胶锥污染的三种消毒剂的有效性。用5种微生物(粪肠球菌ATCC 29212、金黄色葡萄球菌ATCC 25923、白色念珠菌ATCC CBS-ICB/USP 562、枯草芽孢杆菌ATCC 6633和变形链球菌ATCC 25175)的标准化纯培养物污染了60个杜胶球果。用10%聚乙烯吡咯烷酮碘水溶液(PVP-I)处理球果;各组(1、2组)、5.25%次氯酸钠(3、4组)和多聚甲醛片(5组)均能在短时间内对杜仲胶球果进行冷杀菌。

In vitro evaluation of different chemical agents for the decontamination of gutta-percha cones.

This study evaluated the effectiveness of three disinfectants used in Dentistry for decontamination of gutta-percha cones. Sixty gutta-percha cones were contaminated with standardized pure cultures of five species of microorganisms (Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, Candida albicans ATCC CBS-ICB/USP 562, Bacillus subtilis spores ATCC 6633 and Streptococcus mutans ATCC 25175). The cones were treated with 10% polyvinylpyrrolidone-iodine aqueous solution (PVP-I; Groups 1 and 2), 5.25% aqueous sodium hypochlorite (Groups 3 and 4) and paraformaldehyde tablets (Group 5). All chemical agents were efficient for the cold sterilization of gutta-percha cones in short time periods.
