Abstract: BACKGROUND:Work-related musculoskeletal disorders have become a great health issue among dentists. However, it is never been examined among dentists in the State of Kuwait. OBJECTIVES:The purposes of this study were to define the prevalence of work-related musculoskeletal disorders (WMSD) among dentists in the State of Kuwait, to identify risk factors for WMSD, and to explore relationships between WMSD and absenteeism/productivity. METHODS:A descriptive cross-sectional design was used in this study. A self-administered questionnaire was distributed to dentists at government, private, and academic dental clinics. RESULTS:A total of 186 questionnaires were returned (80% response rate). The results showed that 88 (47%) of responding dentists experienced WMSDs. Dentists self-reporting WMSD were older (36.4 (10.3) years vs. 32.6 (9.33); P = 0.01), in practice longer (11.7 (10.4) years vs. 8.2 (8.4); P = 0.013), and worked longer hours (34.9 (10.6) hours vs. 30.4 (11.5); P = 0.08) than dentists not reporting WMSD. A significant association was found between rating of pain and lost days from work (x2 (10, n = 85) = 20.96, ρ = 0.021). CONCLUSIONS:Dentists’ occupational procedures expose their bodies to prolonged and awkward postures, thereby subjecting the dentists to unnatural forces and stresses on crucial movement and functioning joints. Cumulative exposures to such postures lead to WMSDs. Generally, WMSD has a considerable impact on the health and economic status of the individual, family, and workplace. WMSD increases absenteeism and reduces productivity.
