Objective: To compare and analyze the role of micro-ultrasound in the treatment of C-shaped root canal system. Methods: Totally 579 cases of mandibular second molar were treated by oral medicine from June 2014 to May 2016,that 263 cases of C-shaped root canal were divided into two groups. In the experimental group,387 root canals of 132 cases were prepared and filled with nickel-titanium root canal and hot gutta-percha filling technique,and the control group was 131 cases with 383 cases of conventional nickel-titanium root canal preparation and hot gutta-percha filling. Results: The complications of root canal preparation in the experimental group( 8. 3%) was significantly lower than those in the control group( 19. 6%)( P 0. 05),the rate of root canal filling in the experimental group( 95. 5%) was significantly higher than that in the control group( 85. 6%)( P 0. 01),and that in the experimental group was significantly lower than that in the control group( P 0. 01). The success rate of the experimental group was higher than that of the control group( P 0. 05). Conclusion:The application of microsonography can greatly improve the success rate of diagnosis and treatment of C-shaped root canal.
