REGIS FILHO, Gilsée Ivan; MICHELS, Glaycon  e  SELL, Ingeborg. Work related musculoskeletal disorders in dentists. Rev. bras. epidemiol. [online]. 2006, vol.9, n.3, pp.346-359. ISSN 1415-790X.  https://doi.org/10.1590/S1415-790X2006000300009.

Conditions generally named Cumulative Trauma Disorders (CTD) / Work Related Musculoskeletal Disorders (WRMD), that present with signs and symptoms of inflammation in the muscles, tendons, fascia and nerves of the upper limb, shoulder girdle and neck, among others, have been observed not only on account of their incidence but also for their association with work. Dentists are forced to use upper and adjacent structures during their professional activities and frequently perform the same movement pattern, or cause mechanical compression of structures in that area, because of adopting incorrect postures and excessive force, and in most cases due time pressure. This study has employed a cross-sectional epidemiological method to look for evidence on the relation between the tasks dentists perform and CTD/WRMD. Empirical studies have shown the presence of a statistically significant association between both genders and the conditions. Women have presented a greater number of lesions compared to men. Shoulder/arm (39.40%), wrist/hand (18.30%), and neck (17.20%) are the most frequently affected regions. In the present study, analysis of cinematic data has revealed that the main activities dentists perform force two or more regions of the body to positions considered of medium and high risk. Analysis of electromyography signs showed great compromise of flexor and extensor muscle groups of carpi and trapezius. Finally, the present study is one more indication that the tasks carried out are exposing professionals to a considerable risk of acquiring CTD/WRMD.
