The X-Smart Pro+ (Dentsply Sirona) endodontic device has been recently introduced. However, to the best of our knowledge, to date, no ex vivo study evaluating the performance of the X-Smart Pro+ in detecting the apical constriction has been published in English-language journals. To address this gap in literature, our study aimed to evaluate and compare the accuracy of three electronic apex locators (EALs) (X-Smart Pro+, Root ZX mini, and Propex Pixi) in determining apical constriction ex vivo.
Thirty-six extracted single-rooted human maxillary lateral incisors were standardized to a root length of 17 mm. The actual working length (AWL) was determined to be 0.5 mm shorter than the major apical foramen using a #15 K-file. The teeth were then placed in an ex vivo model, and electronic measurements were performed using three different EALs. Statistical analysis was performed on the data using analysis of variance (α = 0.05).
No significant difference was found between the tested EALs in terms of accuracy in determining the apical constriction (P > 0.05). The average distances to the AWL were measured as 0.19 ± 0.36, 0.22 ± 0.21, and - 0.06 ± 0.34 mm for X-Smart Pro+, Root ZX mini, and Propex Pixi, respectively.
Within the limitations of this ex vivo study, X-Smart Pro+, Root ZX mini, and Propex Pixi EALs demonstrated comparable accuracy in AC determination, with no statistically significant differences among the three devices.
X-Smart Pro+（登士柏西诺德公司）牙髓治疗设备最近已推出。然而，据我们所知，迄今为止，尚无在英文期刊上发表的关于评估X-Smart Pro+检测根尖狭窄性能的体外研究。为了填补这一文献空白，我们的研究旨在评估和比较三种电子根尖定位仪（EALs）（X-Smart Pro+、Root ZX mini和Propex Pixi）在体外确定根尖狭窄的准确性。
将36颗拔除的单根人上颌侧切牙标准化为17毫米的根长。使用#15 K锉确定实际工作长度（AWL）比主要根尖孔短0.5毫米。然后将牙齿置于体外模型中，并使用三种不同的EALs进行电子测量。使用方差分析（α = 0.05）对数据进行统计分析。
在确定根尖狭窄的准确性方面，测试的EALs之间未发现显著差异（P > 0.05）。X-Smart Pro+、Root ZX mini和Propex Pixi到AWL的平均距离分别测量为0.19±0.36、0.22±0.21和 - 0.06±0.34毫米。
在这项体外研究的局限性内，X-Smart Pro+、Root ZX mini和Propex Pixi EALs在根尖狭窄确定方面表现出可比的准确性，三种设备之间无统计学显著差异。
