(PO105) Risk Factors and Prevalence of Occupational Musculoskeletal Pain Among Endodontists in the United States

Abstract: A musculoskeletal disorder (MSD) characterized by pain, weakness, numbness, or paresthesia is a common issue for dental healthcare providers. The aims of this study were to: 1) identify the prevalence of MSDs among US endodontists; 2) identify risk factors for MSDs among US endodontists; and 3) compare these findings with other published findings for dental providers. A 24-question survey was distributed to 5,394 members of the American Association of Endodontists (AAE), with 620 responses (11.6% response rate). Analysis focused on 527 surveys from practicing US endodontists. Data was analyzed using descriptive statistics and chi-squared analysis to find significance at α = .05. We hypothesized that the increased implementation of surgical operating microscopes (SOMs) by US endodontists over the past 15 years would result in fewer reported neck problems and overall lower prevalence rates of MSDs than seen in the literature for other dental providers. Results showed that 74% experienced MSDs in the last 12 months, with 88% having had at least one in their career. 85% of females reported an MSD within the past 12 months compared to 70% of males. Notably, 10% missed work due to MSDs in the past year, and 26% missed work at some point in their career. Overall, female endodontists and the frequent adoption of awkward postures were factors associated with significantly higher rates of reported MSDs in the last 12 months. The high prevalence of MSDs among US endodontists underscores the need for increased ergonomics education when using microscopes and further research into prevention and management.
