Abstract(s)
Introdução: A prática de Medicina Dentária implica destreza, precisão e concentração pois centra-se na cavidade oral, local restrito que exige a manutenção de uma postura desviada do normal por um longo período de tempo. Deste modo, é importante alertar para a consciência da Ergonomia no trabalho, e implementar medidas para que seja atingida uma postura equilibrada e dinâmica durante a atividade clínica. O uso de um banco ergonómico, promove uma postura de trabalho em que os principais segmentos corporais (cabeça, tronco, anca e pernas) se encontram dentro dos limites anatómicos favoráveis, reduzindo a prevalência de lesões músculo-esqueléticas.
Materiais e Métodos: Foi efetuado um estudo observacional com Médicos Dentistas e Estudantes do Curso de Mestrado Integrado em Medicina Dentária do Instituto de Ciências da Saúde da Universidade Católica Portuguesa - Viseu, com recurso ao método de Avaliação Rápida dos Membros Superiores (RULA). Todos os participantes utilizaram um banco ergonómico e realizaram uma cavidade classe I, no dente 26, em fantoma. O estudo contou com 20 participantes de ambos os sexos e com idades compreendidas entre os 22 e os 50 anos. Após a recolha de informação, esta foi introduzida e analisada no programa IBM SPSS® Statistics com um limiar de significância estatística de 5%.
Resultados: Os dados obtidos, permitem concluir que os Médicos Dentistas em relação aos Estudantes têm uma pior postura bilateral, principalmente no braço, no antebraço e no pulso, quando realizam a Tarefa 1 (abertura da cavidade). O mesmo se observa na Tarefa 2 (restauração do dente) para a cabeça, o pescoço e as pernas e unilateralmente à direita para o braço, o antebraço e o pulso.
Conclusões: Os Médicos Dentistas, em geral, têm pior postura do que os Estudantes, revelando uma avaliação RULA elevada principalmente nos segmentos corporais da cabeça, ombro e cotovelo. É importante a manutenção de uma postura de trabalho equilibrada e dinâmica por forma a prevenir o aparecimento de lesões músculo-esqueléticas.
Introduction: The practice of Dental Medicine implies dexterity, precision and concentration because it is centered in the oral cavity, a restricted area that demands the maintenance of an out of the ordinary posture for a long period of time. Thus it is important to make people aware of the Ergonomics of the job and implement measures so that a balanced and dynamic posture can be obtained during the clinical activity. The use of an ergonomic stool promotes a work posture in which the main segments of the body (head, trunk, hips and legs) are within favourable anatomic limits, reducing the prevalence of musculoskeletal lesions. Materials and Methods: an observational study was done with Dentists and Students from the Integrated Dental Medicine Course of the Institute of Health Sciences at the Portuguese Catholic University – Viseu with recourse to the method of Rapid Evaluation of the Upper Limbs (RULA). All the participants used an ergonomic stool and performed a mock class 1 cavity, in tooth 26. The study had 20 participants of both sexes and ages between 22 and 50 years. After the collection of the information, it was introduced into and analyzed by the IBM SPSS Statistics program which has a threshold of statistical significance of 5%. Results: The data obtained permitted the conclusion that Dentists in relation to students have a worse bilateral posture, principally in the arm, forearm and wrist, when they completed Task 1 (opening of the cavity). The same was observed in Task 2 (restoration of the tooth) for the head, neck and legs and unilaterally to the right for the arm, forearm and wrist. Conclusions: Dentists in general, have a worse posture than students, revealing an elevated RULA evaluation, principally in the segments of the body, head, shoulder and elbow. It is important to maintain a balanced and dynamic work posture in order to prevent the appearance of musculoskeletal lesions.
