用于直接复合树脂固化的分层技术对于没有经验的学习者来说可能是复杂的，因为在每个步骤中需要许多材料和仪器。本研究的目的是比较和评估分层技术的教学效果分步和所有在一个教学方法在本科牙科学生中的直接复合树脂牙嵌固。MethodsA共68名初级牙科学生参加了这项研究，这是一个前瞻性和单盲试验。将学生随机分为分步式教学组（实验组，n= 34）和一体式教学组（对照组，n= 34）。同一位老师对两组学生进行授课，保证了教学效果的可比性。每个学生的最终分数是两位专家的平均分数，他们对分组不知情。评分系统由五个部分组成。每个部分的评分为3.0、1.5或0。总最高分为15分，最低分为0分。结果专家评分：分步法组15例中的11.29 ± 2.13分，整体法组15例中的9.00 ± 2.71分（t = 3.88，P < 0.001）;此外，实验组所花费的时间明显少于对照组，分别为122.47 ± 2.82和137.18 ± 6.75 min（t = 11.72，p < 0.001）结论直接复合树脂充填的分层技术，逐步组的结果优于一体化组。
BackgroundLayering techniques for direct composite resin restorations might be complicated for inexperienced learners, as a number of materials and instruments are required at each step. The present study aimed to compare and assess the teaching effect of step-by-step and all-in-one teaching methods in layering techniques for direct composite resin restorations among undergraduate dental students.MethodsA total of 68 junior dental students participated in this study, which was a prospective and single-blind trial. The students were randomly divided into a step-by-step group (experimental group,n= 34) and all-in-one group (control group,n= 34). The same teacher taught the two groups, ensuring a comparable teaching effect. The final score of each student was an average of scores by two experts who were blinded to the grouping. The scoring system was consisted by five parts. Each part was assigned scores of 3.0, 1.5, or 0. The total maximum score was 15 and minimum was 0. The total time taken by each group was also calculated.ResultsThe values of the quality of tooth restorations evaluated by experts for step-by-step and all-in-one groups were 11.29 ± 2.13 from 15 and 9.00 ± 2.71 from 15 (t = 3.88,P< 0.001), respectively. In addition, the time spent by the experimental group was significantly lesser than that spent by the control group, which was 122.47 ± 2.82 and 137.18 ± 6.75 min, respectively (t = 11.72,p< 0.001).ConclusionWith regard to the layering techniques for direct composite resin restorations, the outcomes were better in the step-by-step group than in the all-in-one group.
