Abstract Objective: To compare the quality of root canal obturation of C-shaped canal in mandibular second molar by using cone beam computerized tomography (CBCT) and digital periapical radiography (DPR) to assess the advantages and application value of CBCT in C-shaped root canal obturation. Methods: A total of 82 patients (86 mandibular second molars) received root canal therapy in endodontics department. After root canal obturation, the length and density of root filling were assessed with CBCT and DPR simultaneously by two experienced endodontists. Chi-square test was performed to compare the difference between CBCT and DPR in evaluating the quality of the root obturation. Results: With the same root canal preparation and obturation methods, the results varied significantly due to different postoperative evaluation methods. In terms of length and density of root obturation, CBCT was significantly better than of DPR (P<0.05). Conclusion: CBCT is more reliable than DPR in evaluating the obturation quality of C-shaped root canal in mandibular second molar, and has extensive application value in the evaluation of anatomic complex root canal system.

Key words： conebeam computed tomography digital periapical radiography c-shaped root root canal filling
