To evaluate root canal transportation and centering ability as influenced by operator experience using WaveOne Gold files in simulated acrylic resin root canals. Thirty-two simulated acrylic resin canals were distributed to two groups (n = 16). Group 1 is made up of inexperienced students, and group 2 by specialists in the field of endodontics. These canals were shaped to an apical size of 07/25 with the Primary WaveOne Gold file. Photographic images were used to evaluate apical transport and centering of the instrumentation, which was analyzed using Photoshop and Image J image editing software. File separation was also recorded. The data were recorded using Google Forms and analyzed using the R statistical program. The normality of the data was evaluated using the Shapiro-Wilk test, and the t-test was performed to establish differences between the groups. The level of statistical significance was established as p <0.05. The normality of the data was evaluated using the Shapiro-Wilk test. Then statistical significance was analyzed using the T-test. The most remarkable difference when evaluating centering was evident at the 6 mm level. In terms of apical transport, the major discrepancy was at the 1 mm level. However, no significant differences were observed between both groups in any of the points evaluated. A low incidence of instrument fracture was reported. According to our results, the operator's experience does not influence shaping in simulated root canals in terms of centering ability and apical transportation when using WaveOne Gold files.

KEY WORDS: WaveOne Gold, shaping ability, experience, endodontic, apical transport, centering ability.
