“…Furthermore, considering the angular velocities of the right upper arm, both the very low angular velocities for dentists in the present study (8.68/s), and the high angular velocities for assembly workers (52.08/s) seem to be associated with a high prevalence of WMSD in the shoulder/neck region (Christmansson et al 2002, Alexopoulos et al 2004, Dong et al 2007, Hayes et al 2009). For car disassembly workers, the angular velocity was 218/s and the prevalence of WMSD in the shoulder/neck region seemed to be modest (Kazmierczak 2005).…”

“…Only working postures and movements were measured. In a study by Dong et al (2007), a significant interaction was shown between the design of different dental tools and measured physical workload in the lower arms during simulated dental work. The effect of such forces during dental work has not been considered in this study.…”

“…A high prevalence of musculoskeletal complaints is especially found in the shoulder/neck and the back (Alexopoulos et al 2004, Dong et al 2007, Hayes et al 2009). Many studies within the health care sector indicate that physical and mental health problems are partly related to the comprehensive rationalisation when implementing new public management (NPM) and human resource management (HRM) (Winkel and Westgaard 1996, Bejerot et al 1999, Westgaard and Winkel 2011.…”

Objective: To identify the ergonomic factors and the presence of muscular pain in dental students of VIII, IX, X semesters presently practicing at the clinics of the College of Dentistry of university of Cartagena, Colombia, South America. Materials and methods: This is a descriptive study carried out in dental students of the VIII, IX, and X semesters which were undergoing clinical practice at the College of Dentistry of University of Cartagena. A convenience sample of 83 students who met the inclusion criteria was taken and those who agreed to participate signed an informed consent. Data collection was obtained by means of a structured questionnaire for ergonomic factors and the presence of pain was identified palpating the muscles object of the study by a physical therapist. The variables evaluated were: presence of pain, affected muscles, affected zones, gender, postures and work environment. Results: The adoption of inadequate postures such as exaggerated flexions or cervical torsions could generate a higher frequency of muscular pain in dental students. The approximating muscle of the thumb showed 11% frequency of pain. The presence of muscular pain was higher for the female group participating in this study. Conclusions: Dentists are prone, since the beginning of their clinical practice as students, to lesions of the skeletal muscle system due to the clinical exercise of the profession, being the most common, muscle pain in the back, neck, shoulders and hands. This would imply initiating an occupational health program promoting healthy lifestyles in their academic environment and their future professional life, at the beginning of their clinical practice in dental school.

Dentistry is a profession that generally produces muscular pain and soreness, they are usually harmless and slow to appear; consequently, the symptoms are usually ignored until they become chronic and permanent lesions are present. When practicing, dentists sometimes are forced to adopt unhealthy postures which depend mainly on factors related to the working conditions. Also, they are exposed to biomechanical risk factors, which indicates that work forced postures, would imply more risk of soreness and presence of skeletal-muscle lesions. These problems could begin to appear at the beginning of the students learning period, by acquiring inadequate postures and working habits that will accompany them for the rest of their professional life, acquiring an unhealthy lifestyle in their work environment. This can ultimately lead to musculoskeletal disorder (MSD). To protect their own health, dentists should seek out and receive education about musculoskeletal health, and injury prevention during work, by relaxation techniques, breathing and stretching exercises, etc. Very little attention is given on impact of dental work on the development of nerve and muscle pathologies. Therefore, the aim of this review was to critically analyze the literature on the prevalence of musculoskeletal pain and possible aetiology of this problem in dental professionals, and the various postural strategies and stretching and strengthening techniques during breaks to ensure long term comfort, efficiency and ease in dental practice.
