简介 本研究旨在评估和比较牙科技能培训中一体化和分步教学方法的效果。方法 招募了 40 名一年级牙科住院医师参加本研究，这是一项前瞻性、双盲、随机对照试验。学习者被随机分配到一体化组（对照组，n = 20）或循序渐进组（实验组，n = 20）。他们在不同的培训课程结构下对塑料牙进行了牙冠预备。对于全能组来说，课程由教师讲授和演示以及学员练习三部分组成。每个部分依次独立进行。循序渐进组按照牙冠预备程序分为切牙预备、面部预备、邻间预备、舌侧预备、边缘预备、修整抛光六个部分。从教师的讲授、演示到学员的练习，每一部分都按部就班地进行。此后，培训成果由学习者、两名专家和数字系统进行评估。结果 一体组和循序渐进组的成绩，学习者评分为6.15±1.98和8.10±1.41，专家评分为7.00±1.75和8.40±1.10，数字评分为6.43±1.20和7.62±0.51。分别。各评价指标两组比较差异均有统计学意义（P＜0.05）。逐步组获得了更高质量的牙冠预备体。结论循序渐进的教学方法可以提高学习者牙科技能培训的成绩。
Introduction This study aimed to assess and compare the outcomes of all-in-one and step-by-step teaching methods in dental skill training. Methods Forty first-year dental residents were recruited into this study, which was a prospective, double-blind and randomised controlled trial. The learners were randomly allocated to either the all-in-one group (control group, n = 20) or the step-by-step group (experimental group, n = 20). They performed crown preparation on a plastic tooth under different training course structures. For the all-in-one group, the course comprised three parts: the teacher's lecture and demonstration and the learner's practice. Every part was carried out independently in turn. For the step-by-step group, the course was divided into six parts according to the procedures of crown preparation: incisal preparation, facial preparation, interproximal preparation, lingual preparation, marginal preparation, and finishing and polishing. Every part, consisting of the teacher's lecture and demonstration and the learner's practice, was carried out step-by-step. Thereafter, the training outcome was evaluated by the learners, two experts and a digital system. Results For the outcomes of the all-in-one group and the step-by-step group, the learners' assessments were 6.15 +/- 1.98 and 8.10 +/- 1.41, the experts' assessments were 7.00 +/- 1.75 and 8.40 +/- 1.10, and the digital assessments were 6.43 +/- 1.20 and 7.62 +/- 0.51, respectively. In terms of each evaluation index, there was significant difference between the two groups (P < 0.05). Higher quality of crown preparation was attained in the step-by-step group. Conclusion The step-by-step teaching method can improve the learner's achievement in dental skill training.
