Students experience difficulty working with indirect vision and often adopt inadequate working postures because of it. This study created and then assessed the effects of an indirect vision preclinical training programme on dental students' working posture.
The study enrolled students in the third year of the 5-year undergraduate programme in dentistry in the School of Dentistry of São Paulo State University (UNESP), Araraquara (N = 54). The programme consisted of four training sessions in which students performed different types of activities in which only a mirror was used to see the procedure they were performing. To evaluate posture, students were asked to perform class III cavity preparations (distal-palatal and mesial-palatal preparations) on upper central and lateral incisors in a dental mannequin (tooth numbers 11, 12, 21 and 22) both before and after the indirect vision training programme. Photographs were taken of the students' working postures. The photographs were assessed by a duly trained researcher using the Compliance Assessment of Dental Ergonomic Posture Requirements. A descriptive statistical analysis was performed, and the assumptions of normality were verified. Student's paired t test was also performed. The significance level adopted was 5%.
A significant difference was found between the percentages of correct ergonomic postures adopted before and after the training programme (p = 0.039).
The preclinical training programme for indirect vision was found to have a positive effect on the working postures of the students evaluated herein.
学生在使用间接视诊时存在困难，常因此采取不恰当的工作姿势。本研究创建了一个间接视诊临床前培训项目，并评估其对牙科学生工作姿势的影响。
该研究招募了圣保罗州立大学（UNESP）阿拉拉夸拉牙科学院5年制牙科本科项目三年级的学生（N = 54）。该项目包括四次培训课程，学生在课程中进行不同类型的活动，活动中仅使用镜子来观察自己正在进行的操作。为了评估姿势，要求学生在间接视诊培训项目前后，在牙科人体模型（牙齿编号11、12、21和22）上对上颌中切牙和侧切牙进行III类洞制备（远中-腭侧和近中-腭侧制备）。拍摄学生工作姿势的照片。由一名经过适当培训的研究人员使用牙科人体工程学姿势要求合规性评估对照片进行评估。进行了描述性统计分析，并验证了正态性假设。还进行了学生配对t检验。采用的显著性水平为5%。
发现培训项目前后采用正确人体工程学姿势的百分比存在显著差异（p = 0.039）。
本研究发现，间接视诊临床前培训项目对本文所评估学生的工作姿势有积极影响。
