Resumo: Purpose: To compare the accuracy of three electronic apex locators (EALs) and evaluate the influence of cervical preflaring in them. Methods: The working length (WL) of thirty extracted human mandibular incisors was determined visually. All teeth were mounted in conducting medium and tested with: Novapex, Mini Apex Locator and Propex II. The electronic WL was determined before and after preflaring with LA Axxess burs. Differences between the electronic and visual WL were calculated and analyzed by Friedman and Wilcoxon tests. Radiographs were taken using the electronic WL of each EAL and the distance between the instrument tip and the radiographic apical vertex was measured. This value was compared to a reference or ideal value (1 mm) by one-sample t test. Results: The Novapex was the most accurate EAL before and after the preflaring procedure, which was confirmed by the radiographic analysis. All EALs tested increased their accuracy after preflaring, but no significant difference was noted for the Novapex. Conclusion: The Novapex was more accurate compared to the Mini Apex and Propex II. Preflaring procedure was advantageous for all EALs.

Métodos: O comprimento de trabalho (CT) de trinta incisivos inferiores humanos extraídos foi determinado visualmente. Todos os dentes foram montados em um meio condutor e testados com Novapex, Mini Apex Locator e Propex II. O CT eletrônico foi determinado antes e após pré-alargamento com brocas LA Axxess. As diferenças entre o CT eletrônico e visual foram calculadas e analisadas pelos testes de Friedman e Wilcoxon. Radiografias foram realizadas com o CT eletrônico de cada LAE e a distância da ponta do instrumento ao vértice radiográfico foi mensurada. Este valor foi comparado com um valor de referência ou ideal (1 mm) pelo teste t para uma amostra. Resultados: Novapex foi o LAE mais preciso antes e após procedimento de pré-alargamento, o que foi confirmado pela análise radiográfica. Todos os LAEs testados aumentaram sua acurácia após pré-alargamento, mas não foi observada diferença significativa para o Novapex. Conclusão: Novapex foi mais preciso que Mini Apex e Propex II. O procedimento de pré-alargamento foi vantajoso para todos os LAEs.EDIPUCRS - Editora Universitária da PUCRS2011-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/9806Revista Odonto Ciência; Vol. 26 No. 4 (2011); 331 - 335Revista Odonto Ciência; v. 26 n. 4 (2011); 331 - 3351980-65230102-9460reponame: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/9806/7498Morgental, Renata DornellesVier-Pelisser, Fabiana VieiraLuisi, Simone BonatoCogo, Deborah MeirellesKopper, Patrícia Maria Poliinfo:eu-repo/semantics/openAccess2013-11-11T11:44:27Zoai:ojs.revistaseletronicas.pucrs.br:article/9806Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T11:44:27Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
