The purpose of this study was to evaluate and compare the remaining dentin thickness and root canal transportation of WaveOne GOLD, XP-endo Shaper, and GenEndo file systems to assess their performance in curved canals using cone-beam computed tomography (CBCT) imaging.
Seventy-five extracted maxillary first molars were selected with a curvature ranging between 15° and 30°. The samples were allocated into three groups (n = 25) and shaped using WaveOne GOLD, XP-endo Shaper, and GenEndo files. CBCT images were captured before and after instrumentation.
The remaining dentin thickness and root canal transportation were measured at 3, 5, and 7 mm from the apex in both mesiodistal and buccolingual directions. The data were statistically analyzed using one-way ANOVA followed by Tukey's post hoc test.
GenEndo file system demonstrated greater preservation of remaining dentin thickness and resulted in less root canal transportation compared to the WaveOne GOLD and XP-endo Shaper systems across all three levels.
GenEndo file system which comprises multiple files has removed less amount of dentin and canal transportation when compared to single file systems, i.e., WaveOne GOLD and XP-endo Shaper file systems.
本研究的目的是评估和比较WaveOne GOLD、XP-endo Shaper和GenEndo根管锉系统的剩余牙本质厚度和根管偏移情况，以使用锥形束计算机断层扫描（CBCT）成像评估它们在弯曲根管中的性能。
选择75颗拔除的上颌第一磨牙，弯曲度在15°至30°之间。将样本分为三组（n = 25），并分别使用WaveOne GOLD、XP-endo Shaper和GenEndo根管锉进行根管预备。在根管预备前后拍摄CBCT图像。
在根尖上方3、5和7mm处，分别在近远中方向和颊舌方向测量剩余牙本质厚度和根管偏移情况。数据采用单因素方差分析，随后进行Tukey事后检验。
与WaveOne GOLD和XP-endo Shaper系统相比，GenEndo根管锉系统在所有三个水平上都显示出对剩余牙本质厚度的更大保留，并且根管偏移更少。
与单根管锉系统，即WaveOne GOLD和XP-endo Shaper根管锉系统相比，由多个根管锉组成的GenEndo根管锉系统去除的牙本质量和根管偏移更少。
