Abstract: BACKGROUND: Musculoskeletal disorders (MSDs) have been recognized as one of the main occupational health problems for dentists. Many studies have suggested that dentists experience work-related pain or discomfort in the neck, shoulder, and back, as well as in other parts of the body. OBJECTIVE: This study aimed to examine the relationship between specific physical and psychosocial factors and/or ergonomic conditions on MSD symptoms among dentists in Malaysia. METHODS: A group of 85 dentists was asked to complete a questionnaire to determine whether their complaints were related to physical and psychosocial factors and/or ergonomic conditions in their practices. RESULTS: Among the nine reviewed body areas, the shoulders were most often affected by symptoms of MSDs (92.7%). Moreover, MSDs of the neck and upper back were most likely to prevent these practitioners from engaging in normal activities (32.9%). In general, no significant differences were found in the prevalence of MSD symptoms in relation to gender, age, body mass index, years in practice, number of patients, and frequency of breaks. CONCLUSIONS: Our results were consistent with those reported in other studies that focused on MSD problems among dentists in other countries. To reduce the prevalence of MSDs, more attention should be paid to instituting ergonomically sensible approaches in the dental practice setting.
