Abstract
Abstract
Aim: To evaluate the debris extrusion during retreatment using continuous rotation motion of canal obturated with gutta-percha and bioceramic sealer using three different obturation techniques. 
Materials and methods:  A total of forty-two extracted mandibular premolar single canals were used in this study. All teeth were divided into three groups according to obturation techniques (n=14 each); Group (A) using single cone technique (SCT), Group (B) using warm vertical compaction technique (WVC), and Group (C) using lateral condensation technique (CLC). During Retreatment, gutta-percha was removed using ProTaper Universal system retreatment files in continuous rotation motion. Debris extrusion during root canal filling removal was assessed using the microbalance.
 Results:  The highest mean weight of apical Debris extrusion was recorded with WVC technique followed by CLC while the least debris extrusion was recorded in SCT obturation technique. There was a statistically significant difference between group WVC and the other two groups, while there was no significant difference between group SCT and group CLC
 Conclusion: Retreatment of canal obturated using single cone obturation technique and  Bioceramics sealer extruded minimal amount of debris.
