摘要
目的:评价Vectra^(■)三维面像系统在口腔正畸教学中的应用效果。方法:选择空军军医大学2014级口腔医学专业五年制、八年制学生32人作为研究对象,在口腔正畸面部检查诊断实训课中两两一组,进行面部分析,前20 min使用传统二维面像进行分析,后20 min使用Vectra^(■)三维面像进行分析。采用调查问卷让学生对2种教学方法进行量化评价,采用SPSS 24.0软件包对数据进行统计学分析。结果:问卷2、5、6、7项,即在教学方法容易激发学习兴趣、分析准确可靠、主观偏倚小、适合治疗前、中、后的对比分析等4个方面具有组间统计学差异(P<0.05)。问卷1、3、4项,即在教学资料获取方式、教学方法有利于巩固理论知识、操作简便易掌握3个方面,无统计学差异(P>0.05)。结论:Vectra^(■)三维面像系统作为一种新的数字化教学手段,相比传统二维面像更容易激发学生的学习兴趣,分析结果更加准确,主观偏倚小,可重复性强,有助于提高口腔正畸教学效果。
PURPOSE:To evaluate the effectiveness of Vectra^(■)3 D facial imaging technology in enhancing orthodontic teaching and training efficiency.METHODS:Thirty-two dental students,enrolled in 2014 as five-year and eight-year curriculum in School of Somatology,Air Force Military Medical University were selected as the subjects of this research.As an important teaching facility for training the students to practice orthodontic clinical examinations,2 D and 3 D facial imaging systems were selected in this study for the students to collect and analyze the data relating to the facial complexion and appearance.The students were at first instructed to use the traditional 2 D facial imaging system for 20 minutes,and then Vectra^(■)3 D facial imaging system for another 20 minutes.The students were required to deliberate on the specifically designed questionnaires to input their own assessment on these two modalities.The outcomes were quantitatively analyzed using SPSS 24.0 software package.RESULTS:As to the items 2,5,6 and 7 in the questionnaire,which indicated the following queries respectively:whether the use of imaging systems could inspire students’learning interest,whether the results drawn from these two imaging facial systems were accurate and reliable,whether the subjective bias were trivial,and whether these two imaging systems were feasible for orthodontic treatment appraisals.The results showed that there were significant differences in these four items between the two groups(P<0.05).As to the Items 1,3 and 4,namely,whether the acquisition of the teaching materials was an easy access,whether these two facial analytical regimes were beneficial for the students to obtain the new knowledge,and whether this specific teaching facility was easy for the students to manage,there was no significant difference between the two groups(P>0.05).CONCLUSIONS:Served as a new teaching syllabus facilitation,VectraRthree-dimensional facial imaging system demonstrates a more satisfactory impetus for the students to learn than the traditional two-dimensio nal imaging system.Pragmatically,the analytical data resulted from the former remains more accountable than that of the latter.
