A quantitative study on the impact of educational modules on the awareness of postural ergonomics among the dental clinical trainees of Jouf University: A North Saudi Arabian Cohort.

This research aimed to evaluate the difference between self-reported and actual work postures among dental clinical trainees and the effect of health education on their ergonomic postures. Bad postures induce fatigue, musculoskeletal pain, errors, a negative attitude, and job dissatisfaction. It is necessary to evaluate the awareness of posture ergonomics among clinical trainees as the bad postures captured during their learning years transform into habits that could affect future productivity. Hence, a three-level quantitative study was conducted among the dental trainees at Jouf University, Saudi Arabia. The first level comprised a self-reported survey and an observational study to record the working postures of the participants. At the second level, appropriate health education is customized based on the findings observed at the first level. An unannounced observational study was conducted at the third level to assess the impact of ergonomic education on the working postures of the participants. Gender and the academic year level of the participants were the variables considered in the study. The study found that the participants overrated their correct postures (P = 0.005). Fortunately, the final post-ergonomic education observations found a significant improvement in work posture (8.6 vs 12.4), regardless of the variables considered in the study (P = 0.001). The three best correct postures were placing the feet resting on the floor (52.6 vs 92.8 %), using the seat of a dental chair (57.9 vs 89.5 %), and using an upright position of the legs at the thigh-to-leg angle (53.9 % vs 86.2 %). Therefore, the study emphasizes the importance of training in ergonomics and regular, periodic observation to eradicate bad postures before they become a habit among young dentists.
