Background Carpal tunnel syndrome (CTS) and other work-related musculoskeletal disorders (MSDs) are common problems in general industry as well as dental hygiene. The purpose of this study is to determine the prevalence of CTS and other MSDs among dental hygienists. No previous studies involving dental hygienists have combined nerve conduction studies (NCS) and symptoms in their CTS case deQnitions.Methods Dental hygienists (N = 95) completed a symptom and job factors survey, hand symptom diagram, and underwent NCS across the wrist.ResultsAt least one MSD was reported by 93%. Prevalence of CTS was 8.4% utilizing a case deQnition of symptoms and NCS, but 42% if deQned by symptoms alone. Age, BMI, and the number of patients treated per day were signiQcant factors associated with CTS.Conclusions Dental hygienists are exposed to occupational factors that increase the risk of CTS. A case deQnition that does not include NCS overestimates CTS prevalence.
