Comparison of Shaping Ability of T-Endo MUST and WaveOne Gold with Glide Path Instruments: An In Vitro Study

Objective: The aim was to compare the shaping ability and the canal straightening of T-Endo MUST and WaveOne Gold reciprocal file systems with glide path files in resin J-shaped root canals. Material and Methods: Two groups (n=17) were established. TEM tg (13/.04) + TEM M25 (25/.06) and WOG Glider (15/.02) + WOG Primary (25/.07) were used to prepare the resin simulated canals. A series of preoperative and postoperative images were taken by a digital camera and they were superimposed. The curvature angles and the amount of resin removed from both the inner and the outer wall of the canal into the level of 7 mm from the apical point, with a 1 mm increment were measured. The data were evaluated with independent samples Student's t-test with 5% significance interval. Results: There was no statistically difference between TEM and WOG reciprocal files (p>0.05). No instrument fracture or canal aberrations were inspected during canal preparation. Conclusion: Within the limitation of this present study, TEM and WOG files maintained the original canal curvature in curved canals. They produced conservative shapes with lower foramen transportation.
