Risk Factors and Prevalence of Occupational Musculoskeletal Pain among Endodontists in the United States

Abstract

IntroductionA musculoskeletal disorder (MSD) of pain, weakness, numbness, or paresthesia is a common issue for dental health care providers. The aims of this study were to (1) identify the prevalence of MSDs among endodontists in the United States, (2) to identify risk factors of MSDs among United States endodontists, and (3) to compare these findings with other published findings for dental providers. MethodsA 24-question survey regarding the demographics, potential risk factors, and prevalence of MSDs was formulated and distributed to 5394 members of the American Association of Endodontists. Data were then analyzed using descriptive statistics and chi-square analysis to find significance at α = 0.05. ResultsSix hundred twenty participants responded to the survey for an overall response rate of 12%. Of the submitted surveys, 527 of them confirmed to be endodontists practicing in the United States, and all results were derived from those 527 surveys. Seventy-four percent of respondents reported having experienced MSDs in the last 12 months, and 88% reported having experienced at least 1 MSD thus far during their career. Eighty-five percent of female participants reported an MSD within the past 12 months compared with 70% of males. ConclusionsMSDs have a high prevalence among endodontists in the United States. The neck and lower back were the areas of highest MSD prevalence. Female sex and the frequent adoption of awkward postures were factors associated with significantly higher rates of reported MSDs in the last 12 months.
