Resumo
O objetivo deste estudo foi estimar a concordância de dois métodos observacionais, fotografia digital e observação direta, na análise de postura de trabalho em Odontologia. Para tanto, foi realizado o acompanhamento da execução de 50 procedimentos clínicos realizados por alunos do 4° ano de graduação em Odontologia. No momento das avaliações, um examinador devidamente treinado realizou anotações em uma ficha padrão contendo 20 itens que identificaram a postura de trabalho. Simultaneamente, foram realizadas as tomadas fotográficas em posições previamente demarcadas. Após o levantamento de todos os dados, as fotografias foram avaliadas. Para verificação da concordância dos dados nos diferentes métodos, utilizou-se a estatística Kappa com ponderação linear, adotando-se um nível de significância de 5%. Observou-se concordância sofrível (κ = 0,3423) na classificação da postura de trabalho nos dois métodos avaliados. Assim, pode-se concluir que os métodos observacionais de fotografia digital e observação direta apresentaram concordância limitada.

Abstract
The purpose of this study was to estimate the agreement of two observational methods based on digital photographs and direct observation to analyze working postures in dentistry. To this end, 50 clinical procedures performed by fourth year dentistry students were monitored. An examiner, duly trained, took notes on a standard form containing a checklist of 20 items identifying working postures. Simultaneously took photographs in previously delimited positions. After gathering all the data, the photographs were evaluated. The Kappa statistic with linear weighting (κ) was applied to analyze the concordance of different methods with the significant level of 5% to take decisions. The results indicated a fair agreement (κ = 0.3423) in the classification of working postures of the two methods evaluated. Therefore, digital photographs and direct observation of working postures showed a low concordance.
