摘　　要：目的:评价显微超声技术在不完全钙化根管扩通治疗中的疗效。方法:采用显微超声技术对不完全钙化根管进行治疗,统计成功率。结果:70个不完全钙化根管中:44个为根管口,成功扩通43个,成功率为97.7%;20个为根中1/3处,成功扩通10个,成功率为50%;6个为根尖1/3,扩通1个,成功率为16.7%。3组间差异有统计学意义(P<0.01)。结论:显微超声技术为根管治疗提供了行之有效的方法,其中,根管口钙化疗效最好,根尖1/3处疗效最差。Objective：To evaluate the clinical effect of ultrasonic microscope in the treatment of incomplete cal- cification of root canal. Methods： The success rate was calculated after the treatment of incomplete calcification of root canal by ultrasonic microscope. Results：Seventy calcified root canals in molar were negotiated enlarged and obturated. The success rate of orifice portion and middle one - third portion of canal was 97.7% and 50% while the success rate of apical portion of canal was 16%. There were significant difference between any of two among them （P 〈 0.01 ）. Conclusion：The ultrasonic microscope is proved to be effective in the management of calcified root canals and the most effective portion is orifice of canal while the worst is apical.
