This study aimed to compare the healing outcomes of endodontic microsurgery (EMS) using 2-dimensional (2D) and 3-dimensional (3D) radiographic evaluation in a Chinese population. The prognostic factors of EMS were identified according to the 2D and 3D healing classifications.
The teeth (n = 82) were studied using 2D and 3D radiographic examinations. The 2D and 3D healing criteria were used to evaluate the healing outcome. Prognostic factors were investigated based on healing outcomes. Data were analysed using SPSS, and P < .05 was considered significant.
There were significant differences between 2D and 3D healing outcomes (P = .004). For the 3D images, age older than 45 years was found to be a significant negative predictor (P = .005).
Cone-beam computed tomographic images provided more precise evaluation of periapical lesions and healing outcomes of EMS than conventional periapical radiographs. Age (>45 years) of the patients exhibited a significant influence on the healing outcome of EMS as determined using 3D images.
本研究旨在比较二维（2D）和三维（3D）放射影像学评价在中国人群中对根管显微手术（EMS）治疗效果的影响。根据 2D 和 3D 的愈合分类，确定 EMS 的预后因素。
对 82 颗牙齿进行 2D 和 3D 放射影像学检查。采用 2D 和 3D 愈合标准评估愈合效果。基于愈合结果，对预后因素进行调查。使用 SPSS 进行数据分析，P <.05 为差异有统计学意义。
2D 和 3D 的愈合结果有显著差异（P ＝.004）。对于 3D 图像，年龄大于 45 岁是一个显著的负预测因子（P ＝.005）。
与传统根尖片相比，锥形束 CT 图像能更精确地评估根尖周病变和 EMS 的治疗效果。年龄（＞45 岁）对 3D 图像判断的 EMS 愈合结果有显著影响。
