锥形束CT导航在显微牙髓治疗教学中的应用和思考．

Application and thinking of cone beam computed tomography directing technology on teaching of dental microscope treatment to endodontic disease

显微牙髓治疗是牙髓治疗教学中的难点。本研究将锥形束CT导航技术应用于显微牙髓治疗教学，以口腔医学专业七年制五年级学生为教学对象，将教学分为术前CBCT分析规划、术中导航指引、术后疗效评估三阶段，最终以问卷形式获得效果反馈。锥形束CT导航的应用，使传统教学摆脱了仅仅依靠经验的束缚，锻炼了学生的临床思维，提高了其学习积极性和效率，值得推广。

Endodontic treatment with the use of dental operating microscope is a difficult part in teaching.. We have applied cone beam computed tomography （CBCT） guided technology for microendodontic training of dental students who are in their 5th year of the 7 year course to pursue their master＇s degree. The process of teaching is constituted of preoperative analysis, operation guided by CBCT, postoperative therapeutic evaluation. And the result of teaching quality is acquired by questionnaire. This method improved student＇s capacities of analysis and solution in intractable cases and greatly motivated students＇ participa- tion, as well as promoting their learning efficiency. The application of this technique in teaching process compensates the deficiency of traditional teaching method by shaking off the fetters of experience-dependent pattern in the endodontic microscope teaching, and is worth to be popularized in endodontic education.
