Abstract: Objective: To evaluate the effect of PDCA on the quality control of root canal obturation. Methods: The root canal proper-filling rate before and after the application of PDCA was compared. Results: The total root canal proper-filling rate reached the PDCA target. The root canal proper-filling rate of molar improved from 85.84% to 90.45%. There was significant difference in the molar root canal proper-filling rate before and after the PDCA cycle. Conclusion: The application of PDCA facilitates the improvement of molar's root canal obturation and excerts a positive effect on the quality control of root canal obturation.
