INTRODUCTION
Post-treatment periapical lesions present 1 year after treatment may heal during the second year or later. The aim of this study was to assess second-year volumetric changes in post-treatment periapical radiolucencies detected 1 year after treatment.
METHODS
Post-treatment periapical radiolucencies were detected on cone-beam computed tomographic (CBCT) scans obtained from 93 single-rooted teeth 1 year after endodontic treatment. The outcome of these teeth was evaluated 2 years after treatment. Two examiners independently measured the volume of the radiolucencies on CBCT images twice. A Wilcoxon signed rank test was used to assess the 1- and 2-year post-treatment volumes.
RESULTS
The intraclass correlation coefficients for the CBCT volumetric measurements were 0.971 and 0.998 for the 2 examiners, and the interexaminer correlation coefficient was 0.998. Of the 93 teeth with post-treatment radiolucencies at 1 year, 61were examined at the second-year evaluation. The overall size of the radiolucencies significantly decreased during the second year (P = .01); the volume decreased in 38 teeth (63%), remained unchanged in 20 (33%), and increased in 2 (3%).
CONCLUSIONS
The volume of post-treatment periapical radiolucencies detected 1 year after treatment was significantly reduced after the second year in 63% of teeth.
引言
治疗后1年出现的根尖周病变可能在第2年或更晚愈合。本研究的目的是评估治疗1年后检测到的治疗后根尖周透射区在第2年的体积变化。
方法
在根管治疗1年后从93颗单根牙获得的锥形束计算机断层扫描（CBCT）上检测治疗后的根尖周透射区。在治疗2年后评估这些牙齿的结果。两名检查者独立地在CBCT图像上对透射区的体积进行了两次测量。使用Wilcoxon符号秩检验来评估治疗后1年和2年的体积。
结果
两名检查者对CBCT体积测量的组内相关系数分别为0.971和0.998，检查者间相关系数为0.998。在1年时有治疗后透射区的93颗牙齿中，61颗在第2年评估时接受了检查。透射区的总体大小在第2年显著减小（P = .01）；38颗牙齿（63%）的体积减小，20颗（33%）保持不变，2颗（3%）增大。
结论
治疗1年后检测到的治疗后根尖周透射区的体积在第2年后，63%的牙齿显著减小。
