根尖囊肿3种不同根充材料非手术治疗的疗效分析

A clinical study of no-operative treatment to radicular cyst with three different root canal filling materials

目的通过对X线片上直径小于2cm的根尖囊肿患牙用3种不同根管充填材料进行治疗,以观察3种不同材料对根尖囊肿非手术治疗的效果。方法对45例根尖囊肿患者分别使用VITAPEX根管充填糊剂,单纯氢氧化钙(CALXYL)根管充填糊剂,PULPDENT根管充填糊剂各15例。3个月后根据X线片影像学根周骨质变化情况,进行冷牙胶侧方加压法完善根充,并于6个月、12个月、24个月复查。治疗结果通过SPSS分析。结果 VITAPEX根管充填糊剂组治疗有效率100%。CALXYL根管充填糊剂组治疗有效率86.7%。PULPDENT根管糊剂组治疗有效率66.7%。VITAPEX根管充填糊剂组治疗有效率优于PULPDENT根管糊剂组(P<0.05)。而VITAPEX根管充填糊剂组与CALXYL根管充填糊剂组治疗效果没有显著性差异。结论根尖囊肿在囊肿直径小于2cm时,非手术治疗能取得良好的治疗效果。VITAPEX根管充填糊剂治疗有效率优于PULPDENT根管糊剂。而VITAPEX根管充填糊剂与CALXYL根管充填糊剂治疗效果没有显著性差异。

Objective To observe the clinical effect of no-operative treatment to radicular cyst with three different materials, treatment was taken with tree different materials to the radicular cyst of diameter less than 2cm teeth on the X-ray films. Methods 45 cases of radicular cyst were treated by three different materials, that was VITAPEX, CALXYL, PULPDENT. There were 15 cases in each group. 3 months later, treatment was taken by cold gutta-percha filling techniques according bone change around the root by taking X-ray film. The result was analyzed with SPSS software package forx2 test. Results The efficiency rate of VITAPEX group was 100%, the CALXYL group was 86.7%, and the PULPDENT group was 66.7%. There was significant difference between the VITAPEX group and the CALXYL group （ P 〈 0.05 ）. Conclusion No-operative treatment of radicular cyst of diameter less than 2cm was an effective method. The therapeutic effect of VITAPEX group was better than that of CALXYL group. There was no significant difference between the VITAPEX group and the CALXYL group.
