摘要
目的:比较Endom ethasone根管充填糊剂加牙胶尖、传统根管充填剂加牙胶尖在去髓术、根管治疗术一次法根管充填术后的急性反应及近期疗效。方法:选择活髓患牙和适合行去髓术、根管治疗术一次法的患牙共678个,随机分为2组,根管预备后实验组和对照组分别采用Endom ethasone糊剂加牙胶尖、根管充填剂加牙胶尖充填根管。观察2组患牙术后1周内的急性反应及术后3、6个月的疗效。结果:实验组去髓术根充后急性反应率显著低于对照组(P<0.01);实验组根管治疗术根充后急性反应率显著低于对照组(P<0.05)。实验组和对照组中,单根管患牙在去髓术、根管治疗术根充后急性反应率均显著低于多根管患牙(P<0.01)。术后3、6个月复查,实验组去髓术、根管治疗术疗效均稍高于对照组,但无显著差异(P>0.05)。结论:在去髓术、根管治疗术一次法中,Endomethasone糊剂充填根管较根管充填剂可有效地减少术后急性反应的发生。但在近期疗效上两者无明显差异,长期疗效有待进一步观察。
AIM：To compare the acute reaction and the short term therapeutic effect after root filling in one -off RCT and pulpectomy between Endomethasone permanent root canal sealer plus gutta percha and root filling paste plus gutta percha. METHODS ： 632 cases with 678 suffering teeth of alive pulp and those of fit for one - off RCT were chosen and divided into 2 groups in random. The experimental group and the contrast group were filled with Endomethasone sealer plus gutta percha and root filling paste plus gutta percha respectively after root canal preparation. The acute reaction after operation in one week and the short term therapeutic effect in 3 months and 6 months were observed. RESULTS： The rate of acute reaction of pulpectomy in the experiment group is obviously lower than the contrast group （P〈0.01 ） ,and that of RCT in experiment group is conspicuously lower than the contrast group （P〈0.05 ） after root canal filling. The rate of acute reaction of one root canal teeth is obviously lower than that of several root canals teeth after one - off root canal filling both in experiment group and contrast group （ P〈0.01 ）. After 3 months and 6 months, the effective rate of experiment group is higher than the contrast group, but without significant difference （P〉0.05 ） both in pulpectomy and RCT. CONCLUSION： In relation to root filling paster, filling root canal with Endomethasone sealer could effectively reduce the incidence of acute reaction after operation in one - off RCT and pulpectomy. But the short term therateupic effect of Endomethasone sealer was not significant. The long term therapeutic effect needs further survey.
