草药消毒剂,如阿姆拉果汁,花和潘卡图尔西,不会影响古塔珀卡 (GP) 圆的抗拉强度. 然而,3%的甲显著降低了GP的抗拉强度,影响了根管治疗.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 材料科学 材料科学 材料科学
- 牙科材料 牙科材料
背景情况:
- 根管治疗中,Gutta-percha (GP) 是一种至关重要的材料.
- 在处理过程中GP污染需要有效的灭菌方法.
- 消毒剂对GP机械性能的影响需要彻底调查.
研究的目的:
- 用四种溶液消毒后评估和比较GP的抗拉强度.
- 为了评估3%的低酸盐 (NaOCl),果汁 (AJ), (AV) 汁和潘查图尔西 (PT) 作为GP消毒剂的有效性.
主要方法:
- 在实验室内进行了一项研究,使用50个大小为30GP的形.
- 圆被用3%的NaOCl,AJ,AV或PT消毒1分钟,与对照组一起.
- 拉力强度是使用拉力和布里内尔测试机测量的.
主要成果:
- 草药消毒剂 (AJ,AV,PT) 并没有显著改变GP的抗拉强度 (平均值在12.58到13.56MPa之间).
- 3%的NaOCl显著降低了GP的拉力强度 (平均9.49MPa).
- 统计分析包括Kruskal-Wallis和Dunn的后期测试.
结论:
- 阿姆拉汁,汁和潘查图尔西是GP的合适消毒剂,因为它们不会损害拉伸强度.
- 3%的低酸盐应谨慎使用,因为它可以显著削弱GP.
- 进一步的研究可能会探索长期影响和其他机械性质.

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

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...
