离体牙三维重建模型在牙体牙髓病学《根管治疗》教学中的应用

The Application of Reconstructed 3D Extracted Teeth Model in Endodontology Root Canal Therapy Education

摘要: 目的：使用Mimics软件对Micro CT扫描获得的离体牙图像进行三维重建，并将所建模型应用到口腔医学本科生牙体牙髓病学《根管治疗》的教学中，探究其在口腔医学本科生教学中的应用前景。方法：使用Micro CT分别对治疗前、根管预备后以及根管充填后的离体牙进行扫描，并用Mimics软件对扫描获得的数据进行三维重建。将重建得到的三维模型应用到口腔医学本科生的牙体牙髓病学《根管治疗》教学中。通过随堂考试和课后问卷的方式对学生的知识掌握情况进行评价，并与对照组进行对比。结果：在教学过程中应用三维重建模型有效促进了学生对根管治疗的相关知识的理解与掌握。结论：在牙体牙髓病学的教学中应用三维重建模型，不仅有助于学生更清晰地理解根管治疗部分的相关知识，进而提升牙体牙髓教学根管治疗部分的教学质量，更增进了学生对于牙体牙髓病学的学习兴趣，激发了学生的学习热情。

Abstract: Purpose: We used Mimics to rebuild the 3D model of extracted teeth scanned by Micro CT, and put the 3D models into the use of root canal therapy (RCT) education, to explore the application prospect of the above 3D models in endodontics education for stomatology undergraduates. Methods: The extracted teeth were scanned by Micro CT before treatment, after shaping and root canal filling respectively, and the 3D models were reconstructed by Mimics. The reconstructed 3D models were put into use of RCT lessons of stomatology undergraduates. The students’ mastery of RCT between different groups was evaluated through examinations and questionnaires after class. Results: Using the reconstructed three-dimensional model during the teaching process effectively promoted students’ comprehension and mastery of RCT. Conclusion: In endodontology teaching, the application of reconstructed 3D model not only helps students understand the relevant knowledge of the RCT more clearly during the learning process, thereby improving the teaching quality of the root canal treatment of the dental endodontic teaching, but also increases students’ interest in learning endodontics and stimulates their enthusiasm for learning.
