摘要
目的:对不同的操作手法配合EDTA应用于弯曲根管预备中的效果进行研究和评价。方法:105例(123颗患牙,198个弯曲根管)随机分为研究组55例(63颗牙,98个弯曲根管)和对照组50例(60颗牙,100个弯曲根管),初步疏通过程中,研究组采用K锉提拉式疏通,对照组采用旋转向下式疏通,比较两组术后疼痛分级及成功率。结果:研究组患牙1级率明显高于对照组,数据经统计学比较具有极显著差异(P<0.01),提示研究组患者术后疼痛者较少,疼痛程度较轻。研究组根管治疗成功率明显高于对照组,数据经统计学比较具有极显著差异(P<0.01)。结论:EDTA联合根管锉自下而上提拉手法进行弯曲根管预备具有更高的治疗成功率,预防术后患牙疼痛,适用于临床推广。
Objective： To evaluate different operating practices with the EDTA effect on the curved root canal preparation . Method： 105 patients （ 123 teeth, 198 curved root canal）were randomly divided into study group of 55 patients （ 63 teeth, 98 curved root canals ） and control group of 50 patients （60 teeth, 100 curved root canals ） preliminary dredge process, the study group K filing uplifting dredge rotation down to clear the control group, postoperative pain grading and success rate. Result： The rate of teeth with grade me imjwry in study group was significantly higher than that in the control group, the data were statistically highly significant difference （ P 〈0. O1 ） compared with less postoperative pain prompted the study group patients, the pain to a lesser extent. Root canal treatment success rate of the study group was significantly higher, the data were statistically compared with highly significant differences （ P 〈0. 01 ）. Conclusion： Bottom-pulling techniques of the EDTA united root canal file curved root canal preparation with rate, prevention of postoperative teeth pain, apply to clinical. higher treatment success
