摘　　要：目的评价手用ProTaper根管扩大系统对老年人磨牙根管治疗的效果。方法 112例后牙根管治疗病例按就诊顺序分为镍钛根管锉组(PT组)64例,210个根管,采用ProTaper手用镍钛锉,冠根向深入法预备根管;ISO标准型不锈钢K型锉和H型锉组(KH组)58例,201个根管,采用ISO标准型不锈钢K型锉和H型锉,冠根向深入法预备根管。比较2组根管预备后疼痛发生率和根管充填、恰填率。结果试验组患牙根管充填成功率(91%)高于对照组患牙(64%),试验组患牙根管预备及充填术后急性反应发生率(3%)明显低于对照组(21%),差异均有统计学意义(P<0.05)。结论手用ProTaper根管扩大系统预备老年人磨牙根管操作时间短,治疗满意度高,术后并发症少,能有效提高临床工作效率和质量,值得推广。Objective To evaluate the application of hand-use ProTaper instruments in endodontic treatment of aged people molar canals. Methods One hundred and twelve cases who needed root canal treatment were ran- domly divided into two group. The root canals were prepared with hand ProTaper（PT group：64 cases, 210 root canals, gradually forward method）and ISO standard stainless steel type K and H files （KH group： 58 patients,201 root canals, gradually for ward method）, respectively. The pain after preparation and root canal obturation effect were evaluated. Results The rate of satisfactory radiographical results of the test group was 91~ ,which was sig- nificantly higher than 64~f0 of the control （ P d0.05）. The acute reaction rate was 3~, which was significantly lower than 21~f0 of the control（ P 〈~0.05）. Conclusion The application of hand-use ProTaper instruments may improve the effect of aged people root canal treatment of the molars shorten the working time and reduce the post- operative emergencies. It is worth popularizing.
