显微超声技术治疗磨牙中上段不完全钙化根管的疗效分析

目的探讨显微超声技术在治疗磨牙中上段不完全钙化根管的特点并与传统方法临床疗效相比较。方法选择2010年3月～2011年12月本院口腔内科收治66例患者,磨牙中上段不完全钙化根管共83个。随机数字表分配原则分成实验组与对照组各33例,其中实验组使用显微超声技术治疗,对照组行传统方法治疗。结果两组66例83个不完全钙化根管,具体分布于根管口、根中1/3处以及根尖1/3处,两组间根管口扩通成功率显著高于其他位置扩通成功率,实验组各部位扩通成功率明显高于对照组,且扩通时间显著短于对照组,差异具有统计学意义(P<0.05)。结论磨牙中上段不完全钙化根管应用显微超声技术治疗是一种效果显著的方法,与传统方法相比,扩通成功率高,扩通时间短,值得临床推荐与使用。

Effect of microscopic ultrasound in treatment of upper middle segment does not completely molar calcified root canal

Objective To discusses ultrasonic techniques for the treatment of molar microstructure began segment does not completely calcified root canal characteristics, compared with the traditional method, this paper discusses effect. Methods Choose March 2010 to December 2011 were oral medicine of the 66 patients, grind one＇s teeth began to segment does not completely calcified root canal a total of 83. According to table of random number distribution principle into the experi- mental group and the control group with 33 cases in each. Results Two groups of 66 cases of 83 incomplete calcified root canal, distributed in root canal orifice, root of 1/3 and root tip a third place, root canal orifice expansion through the suc- cess rate to a significantly high, each part of the experimental group expansion through the success rate was higher than that of the control group, expanding pass time was significantly shorter than control group, significance of difference （P 〈 0.05）. Conclusion Upper middle segment does not completely molar calcified root canal application microscopic ultra- sound treatment effect significantly, compared with the traditional method, expanding the high success rate, the expansion of short time, it is worth to use.
