Abstract
Background: Up-to-date methods of root canal obturation applying gutta-percha do not provide an accurate and predictable result. The different anatomy of the root canal apical third requires the selection of an optimal method that avoids voids and high sealer content. This study compared standard and modified lateral compaction techniques in root canals with different morphologies using computed tomography. Objective: To come up with an optimal method for filling the apical third of the root canal, considering its anatomical structure and to evaluate the quality of obturation using the computed tomography method. Materials and methods: The research was performed on 46 root canals of extracted teeth. All teeth were divided into two groups depending in the obturation technique used. The study included a lateral compaction technique with modification in oval-shaped root canals, followed by control using computed tomography. Results: Basing on the study, it has been revealed that even at the stage of computed tomography it is possible to plan the most appropriate method of root canal obturation, depending on their shape. Conclusion: To increase the endodontic treatment efficiency it is necessary to take into account the individual anatomical and morphological structure of the root canals. Root canals that have an oval shape in the apical third may require an obturation technique different from a standard one.
