摘　　要：目的探究锥形束CT(cone beam computed tomography,CBCT)及数字化三维重建技术的案例分析结合案例教学法(case-based learning,CBL)在牙体牙髓病学教学中的应用。方法选择2021年9月—2022年1月进行牙体牙髓病学学习的84名贵州医科大学2018级口腔医学专业本科生为研究对象,按照教学方式的不同分为案例组(n=42,CBCT及数字化三维重建技术的案例分析结合CBL教学法)和对照组(n=42,传统教学模式)。比较2组学生总体考试成绩、对口腔异常结构病变掌握程度及教学满意度。结果案例组学生的理论考试、实践考试、病例汇报考试成绩[(83.16±5.84)分、(83.53±2.51)分、(84.34±3.72)分]高于对照组[(80.09±5.72)分、(79.39±3.22)分、(81.24±2.95)分],差异均有统计学意义(P<0.05)。案例组学生对龋齿、牙体缺损、牙髓炎、根尖周炎的异常结构病变掌握程度评分高于对照组,差异均有统计学意义(P<0.05);案例组学生对课堂气氛、学习兴趣、知识掌握、自主学习、师生互动、查阅文献、沟通表达、临床思维、团队合作、学习目标方面的满意度评分高于对照组,差异均有统计学意义(P<0.05)。结论CBCT及数字化三维重建技术的案例分析结合CBL教学法能明显提高学生对口腔异常结构病变的掌握程度,改善教学质量,提高学生满意度。Objective To explore the application of case analysis of cone beam computed tomography(CBCT)and digital three-dimensional reconstruction combined with case-based learning(CBL)in endodontics.Methods A total of 84 undergraduates majoring in stomatology of Grade 2018 in Guizhou Medical University who studied endodontics from September 2021 to January 2022 were selected as the research subjects and were divided into case group(n=42,CBCT and digital three-dimensional reconstruction technology case analysis combined with CBL teaching method)and control group(n=42,traditional teaching mode).The overall test scores,the mastery of oral abnormal structure lesions and the satisfaction of teaching were compared between the two groups.Results The scores of theory test,practice test and case report test in the case group[(83.16±5.84)points,(83.53±2.51)points,(84.34±3.72)points]were higher than those in the control group[(80.09±5.72)points,(79.39±3.22)points,(81.24±2.95)points],and the differences were statistically significant(P<0.05).Students in the case group had higher scores on the mastery of abnormal structural lesions of dental caries,tooth defect,pulpitis and periapical periodontitis than those in the control group,and the differences were statistically significant(P<0.05).The satisfaction scores in the case group on classroom atmosphere,learning interest,knowledge mastery,autonomous learning,teacher-student interaction,literature review,communication and expression,clinical thinking,teamwork and learning objectives were higher than those of the control group,and the differences were statistically significant(P<0.05).Conclusion The case analysis of CBCT and digital 3D reconstruction technology combined with CBL can significantly improve students'mastery of oral abnormal structural lesions,improve teaching quality,and increase student satisfaction.
