摘要

Abstract Aim To compare the cyclic fatigue resistance of R‐ PILOT and WaveOne Gold Glider files in curved artificial canals. Methodology A total of 60 new R‐ PILOT and WaveOne Gold Glider files were tested in artificial canals with 45° and 60° angles of curvature. Fifteen new files of each brand were tested in both canals. Cyclic fatigue resistance was determined by recording the time to file fracture in the artificial canals. The length of each fractured fragment was also recorded. An independent sample t‐test was used to analyse the data. Results In the canal with a 45° angle of curvature, no significant differences were observed between the R‐ PILOT and WaveOne Gold Glider files ( P? ? 0.05). In the canal with a 60° angle of curvature, WaveOne Gold Glider files had greater cyclic fatigue resistance than R‐ PILOT files ( P ??0.05). There was no difference between the files in terms of the lengths of fractured fragments in canals with 45° and 60° angles of curvature ( P ??0.05). Conclusions WaveOne Gold Glider files exhibited greater cyclic fatigue resistance than R‐ PILOT files in artificial canals with a 60° angle of curvature.
