Context: Musculoskeletal disorders affect 100% of dentists practicing in the city of Agadir, Morocco and the association between the development of these disorders and the inappropriate working posture adopted by the dental professional is confirmed in the literature. Aims: The aim of the present study is to assess the knowledge and practices toward ergonomics among dentists working in the private sector in the city of Agadir. Methods and Material: A cross-sectional study was conducted among dentists in the city of Agadir, by using an anonymous questionnaire after informed consent. Statistical analysis used: For the Data entry and statistical analysis, we used SPSS software at the Community Health, Epidemiology and Biostatistics Laboratory of the faculty of dentistry of Casablanca. Results: The respect for the eight rules of working posture is incorrect. It does not exceed 50% for back posture, 21.4% for hands and forearms posture and 31.1% for leg posture. Correct arm posture is the least respected (18.9%). For the participants, the main factors preventing compliance with ergonomic posture are the difficulty of the surgical procedures (73%), time (53.9%) and unsuitable equipment (28.6%). Conclusions: To prevent the observed shortcomings, we propose the integration of work ergonomics into continuing education cycles providing frequent reminders for dentist and dental students. Comparative studies using the same protocol in other cities in our country can be conducted and additional observational studies assessing posture using RULA/REBA, or motion recording sensors should be carried out.
