ABSTRACT

Background: Achieving a hermetic seal by fill a cleaned and shaped root canal while performing obturation during an endodontic treatment procedure is of utmost importance to eliminate all portals of entry between the periodontium and the root canal so as to prevent the toxic product, tissue fluids percolation and recolonization of mcroorganism. The present study aims to evaluate and compare porosity distribution in root canals obturated with Gutta-percha and Bioceramic sealer using different obturating techniques. Materials and Methods: A total of 100 permanent single‑rooted human extracted teeth were divided equally into four groups based on the technique employed: Cold lateral condensation technique, Thermoplasticized obturaton technique, Single cone obturaton technique and Continuous wave compaction technique. Void volume was analyzed by Cone‑Beam Computed Tomography (CBCT) and void location was evaluated by microscopic method at three levels: coronal, middle, and apical. One way ANOVA and Chi‑square test were used for analyzing the obtained results. Results: When the void volumes as seen in CBCT images were compared, all the techniques showed comparable void volume (p = 0.491). The number of voids were lowest in Continuous wave compaction technique followed by Single cone obturaton technique, Thermoplasticized obturaton technique and highest in Cold lateral condensation technique. Conclusion: Continuous wave compaction technique creates least porosity in comparison to Single cone obturaton technique, Thermoplasticized obturaton technique and Cold lateral condensation technique.
