【摘要】：目的观察一次法根管治疗的短期临床疗效,并比较锥形束CT(CBCT)与根尖片在根管治疗结果评估中的差异。方法选择4只比格犬的24颗上颌前磨牙(56个根管)为研究对象,所有牙齿形成实验性根尖周炎后,随机分为2组,一组采用一次法根管治疗,另一组采用两次法根管治疗,术后6个月应用CBCT和根尖片评估根管治疗疗效。结果 CBCT显示:一次法根管治疗成功率为28.57%,二次法根管治疗成功率为53.57%,两组间的成功率差异无统计学意义(P=0.057)。根尖片显示:一次法根管治疗成功率为67.86%,二次法成功率为78.57%,两组间差别无统计学意义(P=0.365)。CBCT显示的根管治疗总成功率为41.07%,根尖片显示的总成功率为73.21%,CBCT与根尖片在根管治疗后疗效评估中的差异有统计学意义(P=0.001)。结论在针对实验性根尖周炎的治疗中,一次法根管治疗的近期治愈率与两次法根管治疗的近期治愈率相比较,其差异无统计学意义;然而,CBCT与根尖片的检查结果,在根管治疗后的疗效评估上,存在着一定差异。由此可见,CBCT这种三维检查手段相较于根尖片的二维影像来说,在根管治疗后对疾病的诊断评估中的准确性以及灵敏度更高。
[Abstract]:Objective to observe the short-term clinical effect of one-time root canal therapy and to compare the difference between CTN CBCTs and apical tablets in evaluating the results of root canal therapy. Methods 24 maxillary premolars (56 root canals) from 4 Beagle dogs were randomly divided into two groups after experimental periapical periodontitis. CBCT and apical tablets were used to evaluate the curative effect of root canal therapy 6 months after operation. Results CBCT showed that the success rate of primary root canal therapy was 28.57 and that of secondary root canal treatment was 53.57.The difference between the two groups was not statistically significant. The apical film showed that the success rate of primary root canal therapy was 67.86 and the second method was 78.57. There was no significant difference between the two groups. The total power of root canal therapy was 41.07, and the total power of root tip film was 73.21 with CBCT and root tip slice in root canal. There was significant difference in the evaluation of therapeutic effect after treatment. Conclusion in the treatment of experimental periapical periodontitis, there is no significant difference between the short-term cure rate of one method root canal therapy and that of two times root canal therapy, however, the results of CBCT and root tip tablets are not statistically significant. There are some differences in the evaluation of the curative effect after root canal therapy. It can be seen that CBCT is more accurate and sensitive in the diagnosis and evaluation of diseases after root canal therapy than in the two-dimensional images of apical radiography.
