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 effect of hand-held ProTaper root canal enlargement on root canal treatment of the elderly. Methods A total of 112 cases of root canal treatment of posterior teeth were divided into NiTi file group (PT group), 64 cases (210 cases) and ProTaper hand nickel-titanium files 58 cases of K-file and H-file (KH group) and 201 root canal of standard stainless steel K-file and H-file of ISO standard type were used for preparation of root canal. The incidence of postoperative root canal pain and root canal filling were compared between the two groups. Results The success rate of root canal filling (91%) in test group was higher than that in control group (64%). The incidence of acute root canal preparation and filling (3%) in experimental group was significantly lower than that in control group 21%), the differences were statistically significant (P <0.05). Conclusion ProTaper root canal enlargement system can be used to prepare the root canal of the elderly with short operation time, high satisfaction of treatment and less postoperative complications, which can effectively improve the efficiency and quality of clinical work and is worth promoting.
