Introduction: Endodontic treatment aims to disinfect and shape root canals through controlled wear of their walls. Selecting the appropriate rotary system is essential for preserving pericervical dentin. To compare pericervical dentin wear produced by three reciprocating Objective: systems (WaveOne Gold, One Reci, and Reciproc Blue). Methodology: An in vitro experimental study was conducted using 30 single-rooted premolars, randomly distributed into three groups of 10 teeth each. Tomographic evaluations were performed before and after instrumentation, measuring mesial, distal, palatal/lingual, and buccal surfaces at 4 mm from the cemento-enamel junction. The Kruskal-Wallis test was used to compare the three systems, with Dunn's post-hoc test for pairwise comparisons (significance level p<0.05). Results: A statistically significant difference was found in the distal sector (p=0.005), with One Reci causing the least wear (0.05±0.02mm) compared to WaveOne Gold (0.21±0.21mm). No significant differences were found in the mesial, buccal, and palatal surfaces. Conclusions: One Reci proved to be the most conservative system for pericervical dentin, suggesting that system selection can significantly impact dental structure preservation during endodontic treatment.
