Prevalence of Scapular Dyskinesis in Working Dentists: An Epidemiological Study

Abstract

Purpose: Assessing and evaluating the prevalence of Scapular dyskinesis among working dentists is the primary priority of the current study. Methods: Both analytical and quantitative cross-sectional investigation was done in a spectrum of 108 dentists of both sexes with ages between 30 and 50 with normal BMI, no history of fractures, surgery, or shoulder impingement, who did not play music or engage in physical exercises like tennis, basketball, or volleyball. The cases were recruited and randomly assigned to four equal groups. The Salutogenic health indicator scale (SHIS), a modified version of the Standardized Nordic Questionnaire, was used to assess the risk factors for scapular dyskinesis. A modified digital inclinometer for measuring the posterior tilting of the scapula during humeral elevation at rest at angles of 45°, 90°, and 120°. Results: Between the four groups, a statistically significant decline in SHIS scores was apparent, and their dominant side was more likely to exhibit scapular dyskinesis. Conclusion: Dentists frequently experience scapular dyskinesis, which can result from overuse, weakness, poor posture, or any combination of these factors. Hence, guiding dentists about proper posture while working and encouraging them to regularly undertake scapular muscle stretching and strengthening exercises would aid in minimizing early muscular fatigue, pain, and scapular dysfunction.
