Musculoskeletal disorders (MSDs) are a common occupational health problem among dental clinicians, affecting their physical well-being and work performance. This study aimed to determine the prevalence of MSDs and evaluate the effectiveness of a structured ergonomic intervention. A cross-sectional study was conducted among 487 dental clinicians from 45 practices between January and August 2024. Baseline assessments used the Nordic Musculoskeletal Questionnaire (NMQ) and Rapid Upper Limb Assessment (RULA). Participants then completed a 6-month intervention including workstation modifications, postural training, and exercise programs.The 12-month prevalence of MSDs was 82.3%, with the neck, lower back, and shoulders most frequently affected. Longer years of practice, extended working hours, and poor ergonomic practices were significant risk factors. After the intervention, pain intensity decreased significantly and RULA scores improved (p < .001).These findings indicate that MSDs are highly prevalent among dental clinicians; however, structured ergonomic interventions can effectively reduce symptoms and improve occupational health outcomes.
