目的 探讨以简化美国正畸学会客观定量评分系统 (American Board of Orthodontics-Objective Grading System,ABO-OGS)为导向的正畸托槽粘接教学(简称为简化ABO-OGS教学)应用效果。方法 2019年5月和2021年5月,选择参与福建医科大学本科口腔医学专业直丝弓矫治器粘接实验课程的200名学生为研究对象。以2017级99名学生为试验组,实施简化ABO-OGS教学;2015级101名学生为对照组采用传统石膏模型教学。教学结束后学生和教师分别填写调查问卷,对2种方法进行评价。组间评分比较采用独立样本t检验。结果 在实验教学方法新颖性方面,试验组学生评分高于对照组,其差异具有统计学意义 [(5.32±0.80)分比(4.99±0.90)分,P=0.006]。教师对简化ABO-OGS教学的评分高于传统教学,如掌握托槽粘接操作[(5.63±0.49)分比(5.17±0.70)分]、学生对托槽准确度认识清晰[(5.58±0.58)分比(5.00±0.78)分]、可增强临床粘接托槽的信心[(5.42±0.78)分比(5.08±0.78)分]等,其差异均具有统计学意义(均P<0.05)。结论 简化ABO-OGS教学改进了正畸托槽定位教学器具,教学方法新颖,有助于建立客观的评价体系,受到学生和教师的欢迎。
Objective To reform the traditional teaching method for bonding of straight wire appliance with plaster models, and build up new teaching method that is more reasonable. Methods In May 2019 and May 2021,the experimental course of straight wire appliance bonding in undergraduate Stomatology of Fujian Medical University was selected as the research objects. The 99 students in grade 2017 adopted the simplified ABO-OGS teaching method as the experimental group, while the 101 students in grade 2015 adopted traditional plaster teaching method as the control group. The students and teachers filled in the questionnaire respectively to evaluate the efficacy of the two methods. The scores of the two groups were compared using independent sample t-test. Results In terms of the novelty of experimental teaching methods, the scores of students in the experimental group were higher than those in the control group, and the difference was statistically significant [(5.32 ± 0.80) vs. (4.99 ± 0.90) , P=0.006]. The teacher's evaluation score of the simplified ABO-OGS teaching is higher than that of the traditional teaching, such as mastering the bracket bonding operation [(5.63 ± 0.49) vs. (5.17 ± 0.70)], students' clear understanding of the bracket accuracy [(5.58 ± 0.58) vs. (5.00 ± 0.78)], and can enhance the confidence of the clinical bracket bonding [(5.42 ± 0.78) vs. (5.08 ± 0.78)], and the differences were statistically significant (all P<0.05). Conclusions The simplified ABO-OGS oriented teaching method reasonably improves the teaching instruments for orthodontic brackets bonding, and the teaching method is novel, which helps to establish an objective evaluation system, and is welcomed by students and teachers.
