Raypex 6 is an electronic apex locator (EAL) that has not yet been tested in vivo. The purpose of this in vivo study was to compare the accuracy of two EALs: the Dentaport ZX and the Raypex 6.
The study involved 36 straight single-rooted teeth. A 10-K file was advanced until the EAL detected the major foramen. The file was fixed in a replaceable pattern of light-cured composite. The apical part of each canal was trimmed to expose the file tip. The distances from the file tips to the major foramen were measured.
Wilcoxon's signed Rank test found no significant differences between the Dentaport ZX and Raypex 6 in terms of their abilities to detect the major foramen (P = .52) The Dentaport ZX was accurate 82.35% of the time to ± 0.5 mm and 97.05% of the time to ± 1 mm, whereas the Raypex 6 was accurate 88.22% of the time to ± 0.5 mm and 100% of the time to ± 1 mm.
No statistically significant differences were observed between the performance of the Dentaport ZX and Raypex 6 EALs under the in vivo clinical conditions used in this study.
Raypex 6 是一种电子根尖定位仪（EAL），尚未在体内进行过测试。本体内研究的目的是比较两种 EAL 的准确性：Dentaport ZX 和 Raypex 6。
本研究涉及 36 颗直的单根牙。将 10-K 文件推进，直到 EAL 检测到大的根尖孔。将文件固定在可替换的光固化复合材料模式中。每个根管的根尖部分被修剪以暴露文件尖端。测量文件尖端到主要根尖孔的距离。
Wilcoxon 符号秩检验发现 Dentaport ZX 和 Raypex 6 在检测大根尖孔的能力方面没有显著差异（P =.52）。Dentaport ZX 在±0.5 毫米时准确 82.35%，在±1 毫米时准确 97.05%，而 Raypex 6 在±0.5 毫米时准确 88.22%，在±1 毫米时准确 100%。
在本研究中使用的体内临床条件下，Dentaport ZX 和 Raypex 6 EAL 的性能没有观察到统计学上的显著差异。
