The three-dimensional obturation of the root canal system is widely accepted as a key factor for successful endodontic therapy. The purpose of this study was to evaluate the obturation of lateral canals and the main canal using three gutta-percha sealer techniques: cold lateral condensation, warm lateral condensation, and warm vertical condensation. Sixty epoxied blocks with five lateral canals placed at varying angles from the main canal were used. Each experimental group was treated by a board-certified endodontist with training and clinical experience in that obturation technique. There was no statistically significant difference (p < 0.05) between the obturation techniques in the ratio of the void area to the gutta-percha-plus-sealer area for the main canal. There was significantly (p < 0.001) more sealer in the lateral canals for the two lateral condensation techniques. The warm obturation techniques had significantly (p < 0.001) more gutta-percha in the lateral canals.

Tomograms taken before endodontic surgery can demonstrate the location of root apices relative to adjacent anatomic structures. This buccolingual perspective is not depicted on conventional periapical or panoramic radiographs. Accurate length determination from the root apex to the inferior alveolar canal is simplified, and the relationship of root surfaces to the buccal and lingual plates is well visualized on the tomographic images.
