Aim: This study analyzed debris extrusion during canal preparation using different file systems for simulated root perforation areas and the apical foramen. Methodology: One hundred thirty-five human mandibular premolars were divided into three main groups, each comprising 45 teeth (n=45), and these main groups were further subdivided into three subgroups, each consisting of 15 teeth (n=15). Group 1 served as the control with no perforations, while Groups 2 and 3 had 0.5-mm-diameter perforation areas created in the apical and middle 1/3 of the buccal root surfaces, respectively. The apical foramen was covered with two layers of nail polish in Groups 2 and 3. In each main group, canals were prepared with (a) hand files, (b) ProTaper Next (PTN: Dentsply Maillefer Ballaigues, Switzerland), and (c) WaveOne Gold (WOG: Dentsply Maillefer Ballaigues, Switzerland). Debris weights extruded from the apical foramen in Group 1 and from the perforation areas in Groups 2 and 3 were calculated. Groups were compared using a two-way ANOVA test. Results: The (a) hand file extruded significantly more debris than the (b) PTN and (c) WOG in Group 1 (Pab<.001, Pac<.001) and Group 2 (Pab=.004, Pac=.005). In Group 3, the a) hand file and the c) WOG file system caused a statistically higher amount of debris extrusion than the b) PTN file system (Pab=.006 and Pcb=.024). During the root canal preparation, the most debris extruded from the apical foramen for hand files, from the apical 1/3 perforation for the PTN system, and from the middle 1/3 perforation for the WOG system. Conclusions: Within the limitations of this study, it can be concluded that all the tested files and the location of the perforation area on the root surface influenced the debris extrusion.
