The aim of this study was to determine the prognostic factors of periapical healing of teeth after single-visit nonsurgical endodontic treatment under general anesthesia in special needs patients.
This retrospective study collected 448 teeth from 241 patients (mean age = 27.4 years, standard deviation = 13.9 years). A total of 271 teeth (60.5%) with clinical and radiographic follow-up records longer than 12 months (mean [standard deviation] = 56.1 [27.9]) were included in the outcome analysis. Demographic, systemic, and dental information about the cases were compared between the healed and nonhealed groups using the Pearson chi-square test. Factors contributing to periapical healing were determined with multivariate logistic regression analysis.
Complete periapical healing without clinical signs was observed in 221 teeth (81.5%), uncertain healing with decreased size of the periapical lesion was shown in 43 teeth (15.9%), and no reduction in lesion size was observed in 7 cases (2.6%). In the multivariate analysis, diet type, oral hygiene maintenance, pulp vitality, and root filling length were detected as contributing factors for complete resolution of periapical lesions (P < .05).
Successful outcomes of single-visit endodontic treatment under general anesthesia were shown in special needs patients. The prognoses were influenced by the clinical circumstances of the patients and the preoperative conditions of their teeth.
本研究旨在确定全麻下单次非手术根管治疗后特殊需要患者根尖周愈合的预后因素。
本回顾性研究共纳入 241 名患者的 448 颗牙齿（平均年龄 27.4 岁，标准差 13.9 岁）。共有 271 颗牙齿（60.5%）具有临床和放射学随访记录超过 12 个月（平均[标准差] 56.1[27.9]），纳入结局分析。采用 Pearson 卡方检验比较愈合组和未愈合组的病例人口统计学、系统和牙科信息。采用多变量逻辑回归分析确定根尖周愈合的影响因素。
221 颗牙（81.5%）完全愈合，无临床症状，43 颗牙（15.9%）显示根尖病变大小减小，不确定愈合，7 颗牙（2.6%）病变大小无缩小。多变量分析显示，饮食类型、口腔卫生维护、牙髓活力和根充长度是根尖病变完全消退的影响因素（P<.05）。
全麻下单次根管治疗在特殊需要患者中取得了良好的效果。预后受患者临床情况和牙齿术前状况的影响。
