Dental ergonomics is among the risk factors; thus, a prompt assessment is crucial in preventing future MSK pain. The aim of this study was to retrospectively assess dental ergonomics of second\u2010year dental students after dedicated lectures were introduced in the predoctoral curriculum.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Three cohorts of second\u2010year dental students were evaluated during preclinical activity in July 2019, January 2022, and December 2022 by an Occupational Therapy (OT) faculty and calibrated OT students. Dental ergonomics was assessed with the Rapid Upper Limb Assessment (RULA). Dental student cohorts were compared with one\u2010way analysis of variance (ANOVA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average RULA final score of 409 participants was 5.1\u00a0\u00b1\u00a00.9, with no difference between the three cohorts (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.676). The January 2022 cohort scored significantly lower in wrist\u2013arm score than that of 2019 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001) and December 2022 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.046). Neck and lower limb posture were significantly higher in January 2022 cohort than in 2019 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001 and 0.013) and December 2022 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.001 and 0.005) cohorts. The December 2022 cohort revealed a medium, high and extremely high risk of developing MSK of 40.2%, 37.1%, and 21.6%, respectively, with no difference between sexes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The risk of developing MSK pain was medium\u2013high in predoctoral dental students and was not related to sex. The overall dental ergonomics required attention and rapid change. Further implementation of varied forms of teaching and monitoring of dental ergonomics from the early years of education is recommended to prevent development of MSK pain at young age and foster better postural habits.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jdd.13338","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T06:45:07Z","timestamp":1690353907000},"page":"1559-1569","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Assessment of dental ergonomics among dental students: A retrospective study"],"prefix":"10.1002","volume":"87","author":[{"given":"Linda","family":"Sangalli","sequence":"first","affiliation":[{"name":"College of Dental Medicine\u2014Illinois Midwestern University Downers Grove Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melisa","family":"Alabsy","sequence":"additional","affiliation":[{"name":"College of Dental Medicine\u2014Illinois Midwestern University Downers Grove Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana","family":"Lingle","sequence":"additional","affiliation":[{"name":"Occupational Therapy Midwestern University Downers Grove Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Alessandri\u2010Bonetti","sequence":"additional","affiliation":[{"name":"Institute of Dental Clinic A.
