Pediatric dentists may encounter musculoskeletal disorders (MSD) when they cannot maintain neutral postures during dental treatments. It is known that dental loupes (DL) can contribute to improving the ergonomic posture of dentists during treatment. This study aims to investigate the effect of wearing DL on the working posture of pediatric dentists.
In pulpotomy procedures performed with DL in 23 patients and without DL in 23 patients, photographs were taken at a total of 3 times in each patient: at the beginning of the procedure, 15 and 30 minutes. The working postures of the clinicians were analyzed using the Modified-Dental Operator Posture Assessment Instrument (M-DOPAI) method through these photographs. The differences between the working postures of pediatric dentists in both groups were analyzed using the Wilcoxon test. The Friedman test determined the statistical relationship between pediatric dentists' time-dependent working postures.
At the beginning, 15, and 30 minutes of treatment, the neck and shoulder postures and the total M-DOPAI scores of clinicians using DL were significantly lower than those working without DL (P < 0.05). However, no significant difference was found among the total scores determined at different time intervals during the treatment (P > 0.05).
The use of dental loupes has been proven to lower ergonomic risk levels related to the working postures of pediatric dentists. By promoting a more neutral neck and shoulder position, dental loupes may help reduce the risk of occupational musculoskeletal disorders.
The trial protocol was retrospectively registered ID NCT06799585 ( https://clinicaltrials.gov/ ); Jan 29, 2025.
儿科牙医在牙科治疗过程中若无法保持中立姿势，可能会出现肌肉骨骼疾病（MSD）。众所周知，牙科放大镜（DL）有助于改善牙医治疗期间的人体工程学姿势。本研究旨在调查佩戴DL对儿科牙医工作姿势的影响。
对23例使用DL进行牙髓切断术的患者和23例未使用DL进行牙髓切断术的患者，在每位患者的治疗过程中总共拍摄3次照片：治疗开始时、15分钟和30分钟时。通过这些照片，使用改良牙科操作员姿势评估工具（M-DOPAI）方法分析临床医生的工作姿势。使用Wilcoxon检验分析两组儿科牙医工作姿势的差异。Friedman检验确定儿科牙医随时间变化的工作姿势之间的统计关系。
在治疗开始时、15分钟和30分钟时，使用DL的临床医生的颈部和肩部姿势以及M-DOPAI总分均显著低于未使用DL的临床医生（P < 0.05）。然而，在治疗期间不同时间间隔确定的总分之间未发现显著差异（P > 0.05）。
已证明使用牙科放大镜可降低与儿科牙医工作姿势相关 的人体工程学风险水平。通过促进更中立的颈部和肩部位置，牙科放大镜可能有助于降低职业性肌肉骨骼疾病的风险。
试验方案于2025年1月29日进行回顾性注册，注册号为NCT06799585（https://clinicaltrials.gov/）。
