The objectives of this cross-sectional analytic study were to factors associated with the degree of risk of musculoskeletal disorders in dental personnel Phetchaburi Province. There were 118 dental personnel in public hospitals of Phetchaburi participated in this study. Data was collected by questionnaire for work-related discomfort, ergonomics risk assessment of working posture assessed by Rapid Upper Limb Assessment (RULA). The results showed that MSDs risk were predominantly found on neck, shoulder, and upper back, and stress was 41.53%. Factors associated with neck pain significantly was marital status
(ORAdj. = 2.87, 95%CI = 1.04-7.89), exercise duration (ORAdj. = 4.49, 95%CI = 1.73-11.63), the size of the working area in the dental clinic (ORAdj. = 9.00, 95%CI = 1.25-64.96), and work stress (ORAdj. = 2.69, 95%CI = 1.10-6.75). Factors associated with shoulder pain significantly was standing posture in dental service (ORAdj. = 2.85, 95%CI = 1.21-6.70), and work stress (ORAdj. = 2.94, 95%CI = 1.24-6.93). Factors associated with upper back pain significantly was congenital disease (ORAdj. = 4.44, 95%CI = 1.11-17.73), standing posture in dental service (ORAdj. = 3.97, 95%CI = 1.33-11.81), and threats in lighting work (ORAdj. = 8.85, 95%CI = 2.52-31.12). The common factors found in neck/ shoulder pain and shoulders/ upper back pain were work stress and standing posture in dental service. The finding risk factors can be the guidance for reducing of the risk of musculoskeletal disorders among dental personal. The suggestions are promoting and encouragement of dental personnel to be aware of the right ergonomic posture, allocate tools or equipment, and workstation suitable for the dental service task and have good physical and mental health.
