ProTaper根管扩大系统联合镍钛K锉在老年磨牙根管术中的应用价值

The Application Value of ProTaper Root Canal System Expansion Combined with Nickel Titanium K File in the Elderly Molar Root Canal Surgery

目的：探讨ProTaper根管扩大系统联合镍钛K锉在老年磨牙根管治疗中的应用价值。方法：收集2012年2月-2013年10月在我院口腔科就诊的156例急、慢性牙髓炎及根尖周炎的老年患者的临床资料，共发现患牙193颗，随机分为3组,A组60颗，B组64颗，C组69颗。A组采用ProTaper手动根管扩大系统联合镍钛K锉预备根管；B组采用ProTaper机动根管扩大系统联合镍钛K锉预备根管；C组采用不锈钢K锉预备根管。对适充率、填充满意率、急症反应发生率进行评定。结果：A、B、C组的适充率分别为为94．02％（110／117）、93．80％（121／129）、62．22％（89／143）；A、B、C组的填充满意率分别为96．58％（113／117）、96．12％（124／129）、58．04％（83／143）；A、B、C组急症反应发生率分别为4．27％（5／117）、4．65％（6／129）、26．57％（38／143）。A、B两组在适充率、填充满意率、急症反应发生率方面相比，无统计学差异（P〉0．05），但分别与C组相比，均显著高于对照C组，差异有统计学意义（P〈0．05）。结论：ProTaper根管扩大系统联合镍钛K锉在老年磨牙根管治疗中的疗效显著。

Objective：To investigate the application value of ProTaper root canal system expansion combined with nickel titanium K file in the elderly molar root canal surgery. Methods： Clinical data of 156 elderly patients with acute and chronic pulpitis and apical periodontitis from February 2012 to October 2013 in our hospital were collected, 193 bad teeth were found and randomly divided into three groups, 60 for group A, 64 for group B, 69 for group C. Group A received treatment of ProTaper system manual endodontic combined with nickel-titanium K file for preparation the root canal. Group B received ProTaper Joint Tactical endodontic combined with nickel-titanium K file system for root canal preparation. Group C was given stainless steel K file for root canal. The appropriate charge rate, filling satisfaction rate and the incidence of acute reactions were assessed. Results： The appropriate charge rates of A, B, C group were 94.02% （110/117）, 93.80% （121/129）, 62.22% （89/143）, the filled satisfaction rates were 96.58% （113/117）, 96.12% （124/129）, 58.04% （83/143） and the incidence of acute reactions were 4.27% （5/117）, 4.65% （6/129）, 26.57% （38/143）. There was no significant difference between A and B groups in the appropriate charge rate, filling satisfaction rate and the incidence of acute reactions （P〉0.05）, but compared with group C, they were significantly higher than those in the control group C, with statistically significant difference （P〈0. 05）. Conclusion：The effect of ProTaper root canal system expansion combined with nickel titanium K file in the elderly molar root canal surgery is distinct.
