This study aimed to provide fundamental data to be utilized in preventing and treating musculoskeletal disorders and analyzing working postures commonly used during periodontal treatment. [Subjects] The subjects were three dental hygienists with work experience in dental clinics for more than 10 years. [Methods] For the analysis of working postures, we simulated the work posture of dental hygienists during the scaling procedures and oral radiographic imaging tasks. The subjects were recorded on video to precisely observe them while they were working. The captured working postures were assessed and analyzed using ergonomic assessment methods, the Rapid Entire Body Assessment, Rapid Upper Limb Assessment, and Strain index. [Results] No differences were exhibited in the intensities of manual scaling and ultrasonic scaling. Commonly, the shoulders and waist were found to be the most overburdened. According to the strain index, manual scaling and ultrasonic scaling working postures were identified to be most dangerous. [Conclusion] The work postures of dental hygienists during scaling are postures that are highly likely to generate work-related musculoskeletal disorders. Therefore, the development of therapeutic exercise programs easily performable in the workplace and daily life is thought to be crucial to prevent work-related musculoskeletal disorders.
本研究旨在提供基础数据，以用于预防和治疗肌肉骨骼疾病，并分析牙周治疗期间常用的工作姿势。[研究对象]研究对象为三名在牙科诊所工作超过10年的口腔保健员。[方法]为了分析工作姿势，我们模拟了口腔保健员在洁治程序和口腔X光成像任务期间的工作姿势。对研究对象工作时的情况进行录像，以便精确观察。使用人体工程学评估方法、快速全身评估法、快速上肢评估法和应变指数对所捕捉到的工作姿势进行评估和分析。[结果]手工洁治和超声洁治的强度没有差异。通常发现，肩部和腰部负担最重。根据应变指数，手工洁治和超声洁治的工作姿势被确定为最危险的姿势。[结论]口腔保健员在洁治过程中的工作姿势很可能会引发与工作相关的肌肉骨骼疾病。因此，开发易于在工作场所和日常生活中进行的治疗性运动方案对于预防与工作相关的肌肉骨骼疾病至关重要。
