目的：研究序贯使用3倍和1倍大牙体雕刻实训教学效果。方法50名口腔医学技术专业学生随机分为实验组和对照组，每组均有25名学生，实验组采用序贯使用3倍和1倍大牙体雕刻实训教学，对照组采用1倍大牙体雕刻实训教学。结果实验组的实训考核成绩明显好于对照组，而实验组的实训考核时间则明显的短于对照组，并且差异具有统计学意义（ P＜0．05）。实验组认为牙体形态的掌握程度有提高的和对实训教学有兴趣的比例明显高于对照组，并且差异均具有统计学意义（ P＜0．05）。结论序贯使用3倍和1倍大牙体雕刻进行实训教学，能够提升学生对实训的兴趣，更加有效地提高实训的效果。%Objective To study the effect of practical teaching on sequential 3 times and 1 times large gypsum tooth carving .Methods 50 The students of stomatology technology professional were randomly divided into experimental group and control group , each group had 25 students, the experimental group used sequential use of 3 times and 1 times the fangs of sculpture , practice teaching , the control group uses 1 times big body sculpture teaching .Results The training examination in the experimental group was significantly better than the control group , while the raining examination time in the experimental group was shorter than in control group , and the differences were statistically significant (P<0.05).The experimental group that the master degree of tooth morphology have improved and are interested in training were significant higher than those in control group , and the differences were statistically significant (P<0.05).Conclusions Sequential use of 3 times and 1 times the fangs of body sculpture practice teaching , can promote the students'interest in training and improve training effect.
