Introdução: O médico dentista necessita de trabalhar com melhor conforto e
visibilidade o que, por vezes, faz com que adote uma postura incorreta,
desajustada e estática, afetando maioritariamente os membros superiores. É
devido ao trabalho periodontal prolongado que os profissionais de saúde oral
estão mais suscetíveis de desenvolver lesões músculoesqueléticas (LME) da
mão e punho, implicando posições de flexão acentuadas do punho/mão, stress
mecânico associado à manipulação dos instrumentos, e força aplicada durante
os procedimentos dentários.
Esta investigação tem como objetivo principal avaliar e analisar a variação da
força de preensão em alunos do 5º ano de medicina dentária. Como objetivo
secundário pretende avaliar a incidência de sinais e sintomas de LME.
Materiais e Métodos: Fezse uma simulação de um procedimento clínico
dentário com recurso a instrumentos de design diferentes em fantomas e, para
avaliar a preensão palmar, foi medida a força de preensão exercida com um
dinamómetro. Foi realizado um questionário para avaliar a incidência de sinais e
sintomas de LME baseado no questionário nórdico NQM. O software IBM®
SPSS Statistics foi utilizado para o tratamento estatístico dos dados.
Resultados: Verificouse que os sintomas mais prevalentes nesta população
foram dor nos ombros, pescoço e zona superior das costas. Durante o
procedimento, 43 participantes acharam a cureta ergonómica mais confortável.
Após a raspagem com a cureta metálica, observouse uma menor força de
preensão palmar.
Conclusão: As mulheres têm uma maior incidência de LME e menor força de
preensão palmar. Os estudantes devem transformar e melhorar hábitos clínicos
para promover melhores condições de trabalho e diminuir LME. Concluiuse que
a força de preensão exercida durante a raspagem radicular depende do design
da cureta. Quando maior o diâmetro e menor o peso, menor será a força de
preensão aplicada ao instrumento.
Introduction: Dentist work requires comfort and visibility, which sometimes causes him to adopt an incorrect, maladjusted and static posture, affecting mostly the upper limbs. It is due to prolonged periodontal work that oral health professionals are more susceptible to developing musculoskeletal disorders (MSDs) of the hand and wrist. This work involves excessive flexion positions of the wrist/hand, mechanical stress associated with instrument manipulation, and force applied during dental procedures. The propose of this study is to evaluate and analyze the variation of grip strength in 5th dental students. We also pretend evaluate the incidence of signs and symptoms of MSDs. Materials and Methods: A clinical dental procedure was simulated using instruments of different design on phantoms and to evaluate the palmar grip, the grip force exerted with a dynamometer was measured. A questionnaire was conducted to assess the incidence of signs and symptoms of MSD based on the Nordic NQM questionnaire. IBM® SPSS Statistics software was used for statistical treatment of the data. Results: It was found that the most prevalent symptoms in this population were shoulder, neck and upper back pain. During the procedure, 43 participants found the ergonomic curette more comfortable. After scraping with the metallic curette, a lower palmar grip strength was observed. Conclusion: Women have a higher incidence of MSD and lower grip strength. Students should transform and improve clinical habits to promote better working conditions and, decrease MSD. It was concluded that the grip force exerted during root scraping depends on the design of the curette. The larger the diameter and the lower the weight, the lower the gripping force made on the instrument.
