The outcomes of an immature tooth with necrotic pulp treated with regenerative endodontic procedures (REPs) were assessed clinically and radiographically. Root maturation is an important outcome of REPs, and several radiographic measurement methods have been used to measure this. The aim of this study was to compare radiographic measurement methods, measuring root maturation in immature teeth with necrotic pulp treated with REPs.
Seventy-one radiographic images of REP cases were measured and compared using 3 radiographic measurement methods described by Bose et al (2009), Alobaid et al (2014), and Flake et al (2014). The intraclass correlation coefficient values were evaluated using the intra- and interobserver reliability test and the effect of the stage of root development.
The intra- and interobserver reliability for Alobaid et al's method and Flake et al's method were slightly higher than Bose et al's method as quantified by the intraclass correlation coefficient without a significant difference (P > .05). The stage of root development did not affect the reliability of the measurement methods. A high level of agreement was found among the 3 stages of root development for all 3 quantitative radiographic measurement methods.
All 3 quantitative radiographic measurement methods exhibited high agreement regarding reliability. The stage of root development did not have an impact on the reliability of the measurement methods.
本研究评估了采用再生性内儿科治疗（REP）的未成熟牙髓坏死患牙的临床和影像学疗效。REP 的重要疗效之一是根尖成熟，目前已有多种影像学测量方法用于评估根尖成熟度。本研究旨在比较评估 REP 治疗未成熟牙髓坏死患牙根尖成熟度的影像学测量方法。
本研究共纳入 71 例 REP 治疗病例的影像学资料，采用 Bose 等（2009 年）、Alobaid 等（2014 年）和 Flake 等（2014 年）描述的 3 种影像学测量方法进行测量，并比较其结果。采用组内相关系数评估观察者内和观察者间的可靠性以及根尖发育阶段的影响。
Alobaid 等和 Flake 等方法的观察者内和观察者间可靠性均略高于 Bose 等方法，但组内相关系数差异无统计学意义（P>.05）。根尖发育阶段对测量方法的可靠性无影响。3 种定量影像学测量方法在根尖发育的 3 个阶段均具有高度一致性。
3 种定量影像学测量方法的可靠性均较高。根尖发育阶段对测量方法的可靠性无影响。
