目的 探讨在口腔医学专业本科学生牙周病学实验课程教学中采用多功能牙周手术教学模型的教学效果。方法 本研究于2016年采用实验对照方法,选择浙江大学医学院2010级～2013级七年制口腔医学专业64名学生为研究对象。在牙周病学实验课程教学中,将2013级32名学生设为实验组,采用多功能牙周手术教学模型(以下简称多功能模型)+多媒体进行教学;2010级～2012级32名学生为对照组,采用传统教学模式(猪颌骨)+多媒体进行教学。教学结束后,采用问卷调查评价两组学生的教学效果。结果 实验组学生与对照组学生对4类牙周切口的掌握人数比较,内斜切口掌握(31比24),外斜切口掌握(31比25),牙间水平切口掌握(32比24),沟内切口掌握(32比24),差异均具有统计学意义(均P<0.05)。实验组学生对教学满意度为[87.5%(28/32)],高于对照组学生[65.6%(21/32)],差异具有统计学意义(P=0.04)。结论 多功能模型满足口腔医学专业学生牙周病学实验教学多种操作训练需求,提高了学生的满意度和操作能力。

Objective To analyze the validity of multiple-functioned periodontal-surgical model used in the simulation-based preclinical practice training course of periodontology by comparing the new model with traditional model(pig jaw).Methods Sixty-four undergraduates of grade 2010-2013 (seven-year program) from the School of Stomatology of Zhejiang University were selected and divided into experimental group and control group.The two group use new model(multiple-functioned periodontal-surgical model) and traditional model(pig jaw) respectively,all combined with multi-media.Questionnaires were used to evaluate the effectiveness between the two groups after the course.Results Mastery of four kinds of periodontal incision between experimental group and control group,the difference had statistical significance.Internal beveled incision:grasped (31 vs 24);External beveled incision:grasped(31 vs 25);Interdental horizontal incision:grasped(32 vs 24);Crevicular incision:grasped(32 vs 24).The degree of satisfaction in practice training course of periodontology of the experimental group was 87.5%(28/32),which is higher than that the control one 65.6%(21/32)(P=0.04).Undergraduates were interested in practice training course of periodontology resulting from the addition surgical training part brought by the new model.Conclusions Multiple-functioned periodontal-surgical model,improving practice ability of students,has the potential of raising students' satisfaction and meet the multiple requirement of preclinical practice training course of periodontology.
