目的通过预期的临床和X线片的研究,评估牙髓治疗时,对比用热牙胶垂直加压充填与侧方加压充填的疗效。方法共有80位患者使用标准逐步后退法技术进行根管预备,然后采用垂直加压充填或侧方加压充填。2年之后,在临床上和X线片上评估治疗结果,使用卡方分析评估有关充填技术的类型。被重新检查的92颗牙齿,有42颗牙齿侧方加压充填,50颗牙齿热牙胶垂直加压充填。结果与术前根尖周损害相比,垂直加压充填比侧方加压充填有更高的成功率P<0.04。不管牙齿术前根尖周损害如何,在统计学上来看在两种技术之间没有显著性差异。两种充填技术的全部的成功率是79%。
OBJECTIVE To evaluate the efficacy of vertical pressure filling and lateral pressure filling with hot denture during endodontic treatment through prospective clinical and radiographic studies. METHODS: A total of 80 patients underwent root canal preparation using standard step-and-repeat technique, followed by vertical compression or lateral compression. Two years later, treatment outcomes were evaluated clinically and on radiographs and chi-square analysis was used to assess the type of filling technique. 92 teeth to be rechecked, 42 teeth side pressure filling, 50 teeth thermal adhesive vertical pressure filling. Results Compared with preoperative apical lesions, vertical compression filling had a higher success rate than lateral compression filling (P <0.04). Regardless of the pre-apical damage to the teeth, there was no statistically significant difference between the two techniques. The overall success rate for both filling technologies was 79%.
