Dentists are susceptible to Musculoskeletal Disorders (MSDs) due to prolonged static postures. To prevent MSDs, working postures of dental students should be assessed and corrected in early career life.
This study estimated the risk of developing musculoskeletal disorders in dental students using Rapid Upper Limb Assessment (RULA) tool.
A number of 103 undergraduate dental students from fourth and fifth academic years participated. Postures of these students were assessed using RULA tool while working in the dental clinic. They also answered a questionnaire regarding their knowledge about postural dental ergonomic principles.
The majority of the students (66%) were at intermediate and high risk levels to develop MSDs and their postures needed to be corrected. There was no significant correlation between RULA score and gender, academic year and different wards of dental clinics. There was no significant correlation between knowledge and RULA scores.
Dental students did not have favorable working postures. They were at an intermediate to high risk for developing MSDs which calls for a change in their working postures. Therefore students should be trained with ergonomic principles and to achieve the best results, ergonomic lessons should be accompanied by practice and periodical evaluations.
由于长时间保持静态姿势，牙医易患肌肉骨骼疾病（MSD）。为预防MSD，应在牙科学生职业生涯早期对其工作姿势进行评估和纠正。
本研究使用快速上肢评估（RULA）工具评估牙科学生发生肌肉骨骼疾病的风险。
103名来自第四和第五学年的本科牙科学生参与了研究。在牙科诊所工作时，使用RULA工具对这些学生的姿势进行评估。他们还回答了一份关于其对姿势性牙科人体工程学原理知识的问卷。
大多数学生（66%）处于发生MSD的中高风险水平，其姿势需要纠正。RULA评分与性别、学年以及牙科诊所的不同科室之间无显著相关性。知识与RULA评分之间无显著相关性。
牙科学生的工作姿势不佳。他们发生MSD的风险处于中高程度，这就需要改变他们的工作姿势。因此，应该对学生进行人体工程学原理培训，为达到最佳效果，人体工程学课程应辅以实践和定期评估。
