中药制剂用于超声根管预备的初步研究

目的评价中药制剂洁尔阴与超声波联合应用杀灭感染根管内厌氧菌的效果。方法将临床诊断为慢性根尖周炎的60例患者的60颗患牙随机分为3组（每组20颗牙），第1组为传统手持器械对照组，第2组为超声生理盐水对照组，第3组为超声洁尔阴实验组。根管清理前后分别取样进行厌氧培养。结果传统手持器械组与超声生理盐水组之间差异有显著性（P<0.05）；超声洁尔阴组与超声生理盐水组之间差异有极显著性（P<0.01）。结论超声波在根管杀菌方面有独特的优势，中药洁尔阴可有效地杀灭感染根管内的厌氧菌，是符合生物学原则、较理想的超声根管冲洗液。

A study on the use of traditional Chinese medicine agent in ultrasonic instrumentation of root canals

Objective To evaluate the bactericidal effect for anaerobes of infected root canals using Chinese medicine agent Jieeryin combing with ultrasonic technique Methods 60 single rooted teeth in patients with chronic periapical periodotitis were divided into 3 groups randomly, 20 in each Hand instruments were used for group 1 as control group of traditional treatment Ultrasound with saline as irrigant were used for group 2 as control group Ultrasound with Jieeryin as irrigant were used for group 3 as experimental group The pre instrumentation and post instrumentation specimens of each root canal were placed into the anaerobic chambers and incubated Results Significant difference was found between hand instruments group and control group of ultrasound ( P <0 05) and even more significant difference was found between control group of ultrasound and experimental group of ultrasound ( P <0 01) Conclusions Ultrasound has special superiority on instrumentation and bactericide of root canals Chinese medicine agent Jieeryin can kill anaerobes in infected root canals effectively It is an ideal irrigant for ultrasound which conforms to principles of biology
