Objective: The main cause of this in vitro study was to measure and compare the amount of debris extruded apically using three NiTi single rotary files (primary WaveOne Gold file, Hyflex EDM file, and the XP-endo Shaper).  

Methods: Palatal root of sixty freshly extracted human maxillary molar teeth were sectioned at 12 mm, and inserted through the center of a rubber stopper of a pre-weighed collecting vial except for the coronal quarter of the root. Then separated three groups in accordance with their (n =20) system. G I: primary WaveOne Gold single file system (Dentsply-Maillefer, Ballaigues, Switzerland)., G II: Hyflex EDM single file system (Colten/Whaledent, Germany). and G III: Xp-endo Shaper single file system (FKG, Switzerland) used, the 1mm irrigation with distilled water applied for washing the instruments, apical debris was collected and dried at 100° C. Sequential weights were obtained for each vial, and the distinction between the weights of the vial (pre- instrumentation and post- instrumentation), considered debris weight. Data were analyzed statistically using the One-way ANOVA test and LSD test, p≤ 0.05 was considered for data analysis value.      

Results: All rotary systems applied in this study showed apical extrusion of debris. GIII showed the significantly highest amount of debris (p< 0.001) compared to GI and GII, whereas, mean value differences of Hyflex and WaveOne Gold were statistically non- significant (p>0.05).  

Conclusions: The Hyflex EDM showed the lowest mean value of debris extruded apically compared to WaveOne Gold and Xp-endo Shaper. XP-endo Shaper had the highest mean value of debris extruded apically.
