目的研究视频反馈教学方法在口腔修复牙体预备实践教学中的应用效果。方法研究于2022年12月至2023年3月在第四军医大学口腔医院教学中心虚拟仿真中心进行。选取即将进入临床实习的第四军医大学口腔医学专业2020级本科生30名,采用随机数字表法分为研究组和对照组,每组15名。研究组与对照组学生分别采用视频反馈教学方法和传统教学方法进行口腔修复牙体预备专项集中培训。2组学生于培训前后在仿真头颅模型上完成上颌中切牙全冠修复牙体预备操作考核,比较2组操作体位评分(分值越低提示体位越佳)和牙体预备形态评分(分值越高提示预备效果越好)。考核结束后研究组学生匿名填写视频反馈教学方法效果调查问卷。结果培训前,研究组与对照组的牙体预备形态评分、操作体位评分比较,差异均无统计学意义(均P>0.05)。培训后,2组牙体预备形态评分均较培训前显著提高,操作体位评分均较培训前显著降低,且研究组操作体位评分[(17.73±2.12)分]较对照组[(19.80±1.86)分]更低,差异均有统计学意义(均P <0.05);但2组牙体预备形态评分比较,差异无统计学意义(t=-0.507,P=0.616)。考核结束后对研究组学生进行问卷调查发现,学生对视频反馈教学方法评分较高,各项评分均在4分以上;尤其在提高教学活动中注意力、愿意采用该方法进行实践训练课学习方面评分较高。结论与传统教学方法相比,应用视频反馈教学方法于口腔修复牙体预备实践教学中可更好地规范操作体位,具有较高评价反馈,值得进一步探究和应用。
