Abstract

Objective: To compare the effects of HyFlex EDM(HEDM), WaveOne Gold (WOG), XP-Endo Shaper (XP), Reciproc (R) and ProTaper Next (PTN) systems on transportation, centering abilities, and canal volume in the preparation of curved root canals using the micro-CT imaging technique, to evaluate the changes on the surfaces of Ni-Ti instruments after use by SEM, and to compare the preparation times.

Materials and Methods: 40 mandibular molar teeth with Vertucci Type IV were included in this study after the initial micro-ct scanning. Access cavities were opened. The working length was calculated. Five different Ni-Ti systems were used to prepare the samples(n=16): HEDM, XP, WOG, R, PTN. During the preparation, the root canals were irrigated with 5 ml of 5% NaOCl and 10 ml of distilled water. Prepared samples were rescanned by micro-CT. The canal volume, the working times, canal transportation, transportation direction, and centering ability were evaluated for each group.

Results: The transportation of PTN, HEDM, and WOG groups is significantly higher than XP (p < 0.005), whereas the transportation of WOG is not significantly differenct than R. No statistically significant difference was found between the centering ability of the groups (p > 0.05). Similarly, there is no significant difference in the direction of transportation between PTN, R, WOG, HEDM and XP (p > 0.05). there was no significant difference between the post-preparation volume between the groups (p > 0.05). the working time of HEDM is significantly longer than PTN, R, WOG, and XP (p < 0.005). No instrument fracture was observed in any groups during the preparation of root canals.

Conclusion: the XP caused significantly less transportation than other Ni-Ti systems, but none of the file systems used had an excellent centering ability. No significant difference was found in transportation direction, centering ability, and volume change after preparation between HEDM, XP, WOG, R and PTN.
