Resumo: Purpose: The aim of this work was to evaluate bone age assessment using two simplifications of the Eklof and Ringertz method, which provide automated auxiliary data for the medical diagnosis. Methods: Hand radiographic images of 685 children and adolescents (male and female subjects; age: 6-16 years old) were used to estimate skeletal age using simplifications of the Eklof and Ringertz method – ER5 and ER3 (five and three hand bone ossification centers, respectively). Data were analyzed using Pearson’s correlation test and Student’s t-test (0.05 level of significance). Results: The values of bone age estimation using the two simplifications of the Eklof and Ringertz method were compatible with the average medical reports obtained by using three standard methods – Greulich & Pyle, Tanner & Whitehouse and Eklof & Ringertz methods. In most cases no statistically significant difference in bone age was found (P > 0.05). Conclusion: It is possible to conclude that both proposed simplifications (ER3 and ER5) can be used for bone age estimation, using fast and simplified configuration, with results similar to the average of the traditional methods. Also, these simplifications are appropriate to estimate bone age in large databases because they are fast and objective.

Metodologia: Foram utilizadas imagens carpais de 685 crianças e adolescentes na faixa etária de 6 a 16 anos para a estimação da idade óssea com as simplificações E&R5 – simplificado para 5 centros de ossificação; E&R3 – simplificado para 3 centros de ossificação. A automatização dos métodos simplificados explora procedimentos específicos para o processamento de imagens radiográficas da mão. Resultados: Os resultados obtidos na estimação com as duas simplificações propostas foram compatíveis com a média dos laudos médicos obtidos com os três métodos clássicos – Greulich & Pyle, Tanner & Whitehouse e Eklof & Ringertz. A verificação foi realizada utilizando o teste T de Student pareado com faixa de significância de 5% e, na maioria dos casos, não ocorreram diferenças estatisticamente significantes (P > 0,05). Conclusão: Analisando os resultados, conclui-se que é possível estimar a idade óssea utilizando a simplificação do método de E&R, no qual o processo de estimação é feito de forma rápida e automatizada, obtendo resultados compatíveis com o laudo médico.EDIPUCRS - Editora Universitária da PUCRS2009-09-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlecross-sectionalapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/5268Revista Odonto Ciência; Vol. 24 No. 4 (2009); 361 - 366Revista Odonto Ciência; v. 24 n. 4 (2009); 361 - 3661980-65230102-9460reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/5268/4775Olivete Junior, CelsoLuís Linhari Rodrigues, Evandroinfo:eu-repo/semantics/openAccess2013-11-11T12:57:32Zoai:ojs.revistaseletronicas.pucrs.br:article/5268Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:57:32Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
