Comparative CBCT Assessment of Obturation Quality in Different Obturation Techniques

Abstract

Introduction: Different techniques and materials have been introduced over time to improve the quality of root canal treatment. This study aimed to compare the quality of root canal obturation using three root canal obturation techniques based on the existing void using cone beam computed tomography imaging techniques. Methods: Thirty-three single canal teeth were selected and the root canals were prepared. The roots were obturated with single-cone, lateral compaction with cold gutta-percha, and vertical compaction techniques. Afterward, the roots were scanned, and the presence of voids in the 1-, 3-, 5-, and 7-mm sections of the root apex was investigated, and then the area and volume of voids were calculated by Mimics 10.01 software. Results: The highest percentage of voids presence in all groups was detected in the 7-mm section of the apex (60.6%) , while the lowest percentage was found in the 1-mm section of the apex (12.1%). Conclusion: There was no significant difference between the three techniques evaluated in this study in terms of void size, void volume, and obturation quality. Voids were present in all samples. Considering the technique used to obturate the root canals, voids were different in terms of shape and volume
