This study aims to examine the prevalence of musculoskeletal disorder (MSD) symptoms in allied dental professionals (ADPs) in Saudi Arabia and risk factors for MSDs. The study also explores ADPs' opinions and attitudes about the effect of MSD symptoms on the quality of life and potential mitigatory measures. This is a prospective cross-sectional study. Participants were 355 licensed dental staff (average age 33.6 ± 8.1 years, 69% women) working as assistants, lab technicians, radiology technicians, or sterilization technicians with at least six months' work experience. The self-administrated questionnaire comprised socio-demographics, work-related factors, and items from the Nordic Musculoskeletal Questionnaire. Multivariate and univariate logistic regressions were conducted to investigate risk factors for MSD symptoms. Overall, 93% of ADPs complained of MSD symptoms in at least one body site in the past 12 months. Factors related to work conditions (e.g., 'keeping an uncomfortable posture for long periods of time', 'lifting heavy objects') and years of experience were proven to be significant risk factor for developing MSDs. The cohort of ADPs showed a high MSD symptoms prevalence. Efforts are imperative in addressing the risk factors of ergonomics and the workplace environment, and more rigorous studies are needed to further investigate risk factors.
