摘要/Abstract

摘要： 目的: 比较锥形束CT及相关软件与全景片在口腔颌面影像教学中的效果。方法: 选择38名进入口腔临床实习的2011级七年制口腔医学专业学生为研究对象,对同一病例的全景片及CBCT数据进行分析。测量切牙管内径（A）、上颌尖牙髓腔长度（B）、上颌第一磨牙根分叉与上颌窦的距离（C）、下颌第三磨牙牙根与下颌神经管的距离（D）,并观察前磨牙的根管形态。采用SPSS 16.0软件包分析学生在2种图像上的测量结果,评价教学效果;同时发放调查问卷,了解学生对传统二维及三维影像的理解及评价。结果: 统计结果显示,全景片上测出A数据3人,B数据14人, C数据10人,D数据16人;CBCT上测出A数据38人,B数据36人,C数据37人,D数据38人。 χ²检验显示,4组数据间有显著差异（P<0.05）。38名学生均完成调查问卷,95%以上的学生认为基于CBCT的案例教学能够激发兴趣、加深理论知识理解、提高临床思维能力。结论: 在口腔颌面影像教学中,运用CBCT数据及相关软件,对具体病例进行测量分析,能帮助学生建立三维影像概念,提高学生对口腔影像学习的积极性,提高临床教学效果。

Abstract: PURPOSE: To compare the teaching result of case-based learning based on cone-beam CT (CBCT) software and traditional pantomography. METHODS: Thirty-eight interns (7-year programme) of grade 2011 from College of Stomatology, Shanghai Jiao Tong University were enrolled. The inner diameter of the nasopalatine ducts (A), the length of upper canine's pulp cavity (B), the length between root furcation of upper first molar and the maxillary sinus (C), the length between the root of lower wisdom tooth and the inferior alveolar nerve (D) were measured on pantomographic films and CBCT in the same case. The results of 38 interns were evaluated by Chi-square test with SPSS 16.0 software package. A questionnaire, given to the whole group of interns, was used to evaluate the teaching effect and the understanding of the 2D and 3D conception of the radiologic films. RESULTS: Only 3 data A, 14 data B, 10 data C, and 16 data D were measured on pantomography, respectively. Thirty-eight data A, 36 data B, 37 data C, and 38 data D were measured on CBCT. Significant difference was found between measurements on CBCT and pantomography in 4 groups (P<0.05). 38 interns finished the questionnaires survey. More than 95% interns delivered positive comments in inspiring interest, deepening knowledge, improving clinical thinking ability, and etc. CONCLUSIONS: Case-based learning based on CBCT software for measuring anatomic structures and building 3D concept can improve the quality in oral and maxillofacial radiology learning, deepen the understanding of the specialty, and increase efficacy of clinical teaching.
