Work-related disability is caused commonly due to musculoskeletal disorders (MSD) in dentistry. Prolonged static awkward and repetitive postures cause MSD in dentists. The study was executed to confirm the development of MSD in various body regions as they have to work in a small oral cavity to perform crucial dental procedures with precision and concentration.
To assess the occurrence of the MSD in several body regions of dentists and to carry out postural study thereby helping them improve posture.
Dentists were assessed for their current working postures with various MSD symptoms and its effects. The questionnaire was devised to get musculoskeletal health data from dentists. The postural load was investigated using Rapid Upper Limb Assessment (RULA). Various risk factors contributing to MSD symptoms were identified after data were statistically analysed using IBM SPSS version 27.
According to the current study neck, shoulder, lower back, upper back, wrist hand, elbow, hip, thigh, knee, and ankle were the most affected anatomical regions. Average RULA score for the current study was found to be 6.75 which indicated a need of change of posture while performing dental procedures. There is statistical correlation between gender, Body Mass Index (BMI), uncomfortable positions, stretching, use of ergonomic saddle chair, hand dominance and MSD. There is no statistical correlation between years of experience and MSD.
Current workstation (Dental Chair) requires immediate improvements as evident from the postural load analysis, thus immediate implementation of intervention program is required.
牙科工作相关的残疾通常由肌肉骨骼疾病(MSD)引起。长时间的静态别扭和重复姿势会导致牙医患上MSD。开展这项研究是为了确认不同身体部位MSD的发展情况,因为牙医必须在狭小的口腔内工作,精确且专注地进行关键的牙科手术。
评估牙医身体多个部位MSD的发生情况,并进行姿势研究,从而帮助他们改善姿势。
评估牙医当前的工作姿势以及各种MSD症状及其影响。设计问卷以获取牙医的肌肉骨骼健康数据。使用快速上肢评估(RULA)来调查姿势负荷。在使用IBM SPSS 27版对数据进行统计分析后,确定了导致MSD症状的各种风险因素。
根据当前研究,颈部、肩部、下背部、上背部、手腕、手部、肘部、臀部、大腿、膝盖和脚踝是受影响最严重的解剖区域。当前研究的平均RULA评分为6.75,这表明在进行牙科手术时需要改变姿势。性别、体重指数(BMI)、不舒服的姿势、伸展、使用符合人体工程学的马鞍椅、用手习惯与MSD之间存在统计学相关性。工作年限与MSD之间没有统计学相关性。
从姿势负荷分析可以明显看出,当前的工作站(牙科椅)需要立即改进,因此需要立即实施干预计划。
