In a previous study, we evaluated the outcomes of endodontic microsurgery by comparing the healing success of cases involving a lesion of endodontic origin with cases involving a lesion of combined endodontic-periodontal origin. Of the 188 teeth over the 5-year period, 172 (91.5%) were considered to be successes. The purpose of this study was to evaluate the outcomes, up to 10 years, of the cases that were classified as successes in the previous study.
The 172 cases that were considered to have successful outcomes in the previous study were included. Patients were followed up every 6 months for 2 years and every year up to 10 years. On every follow-up visit, clinical and radiographic evaluations were performed according to the same criteria as in the original study by the same 2 examiners.
A follow-up rate of 60.5% (104/172 cases) was obtained. Of the 104 followed-up cases, 97 cases were included in the successful group, 91 with complete healing and 6 with incomplete healing. The overall maintained success rate was 93.3%. The failure group, which meant a reversal to disease, included 7 cases with unsatisfactory healing.
In this study, 93.3% of endodontic microsurgery cases that were considered healed in a prior 5-year study remained healed after more than 6 years.
在之前的一项研究中，我们通过比较牙髓病变和牙髓-牙周联合病变病例的愈合成功率来评估根管显微镜手术的结果。在 5 年的时间里，共有 188 颗牙齿，其中 172 颗（91.5%）被认为是成功的。本研究旨在评估前一项研究中被分类为成功的病例在 10 年内的结果。
本研究纳入了之前研究中被认为有成功结果的 172 例。患者每 6 个月随访 2 年，然后每年随访至 10 年。在每次随访中，临床和影像学评估均按照与原始研究相同的标准，由两名相同的检查者进行。
获得了 60.5%（104/172 例）的随访率。在 104 例随访病例中，97 例被归入成功组，其中 91 例完全愈合，6 例不完全愈合。总的保持成功率为 93.3%。失败组意味着病情逆转，包括 7 例愈合不满意的病例。
在这项研究中，在之前的 5 年研究中被认为已经愈合的根管显微镜手术病例中，有 93.3%在 6 年以上时间后仍然保持愈合。
