Resumo: Abstract Purpose:This study evaluated the morphological alterations that occur in rotary nickel-titanium instruments during nitrogen-ion implantation. Methods: Instruments were divided into three groups: Group A- ProTaper SX instruments were subjected to ionic implantation with bands of nitrogen ions at 100 keV, ion dose was 1.0 X 1017 ions/cm², Group B- ProTaper SX instruments were subjected to ionic implantation with bands of nitrogen ions at 200 keV, ion dose was 1.0 X 1017 ions/cm², and Group C instruments served as unmodified controls. Each instrument was utilized to prepare five canals in epoxy resin blocks with a brushing motion. The instruments were examined by scanning electron microscopy (SEM) before use and after 60 s and 300 s of work inside canals in epoxy resin blocks. Results: Material loss and distortion were statistically similar in all groups. However, while only one instrument in group A and only one instrument in group B fractured during use, three instruments in group C fractured during use. Conclusion: Nitrogen ion implantation can improve the properties of nickel-titanium rotary instruments. However, widespread adoption by the dental industry may not yet be tenable due to the cost (nitrogen ion implantation is a costly process) and relatively small benefit.

O grupo B foisubmetido a uma dose de 1,0×1017 íons de nitrogênio/cm² e energia de 200 KeV. O grupo C foi composto por dez instrumentos não submetidos ao processo de implantação iônica. Cada lima instrumentou cinco blocos de canais simulados de resina acrílica, com a técnica Brushing Motion. Todos os instrumentos SX foram analisados no Microscópio Eletrônico de Varredura antes do uso, após 60 s e 300 s de uso.Resultados: A perda de material e a distorção foram estatisticamente similares em todos os grupos. Um instrumento do grupo A, um instrumento do grupo B e três instrumentos do grupo C fraturaram durante o uso.Conclusão: A Implantação Iônica de íons de nitrogênio melhorou moderadamente o desempenho dos instrumentos ProTaper SX. Instrumentos implantados apresentaram melhores resultados do que o grupo controle, sem diferença estatisticamente significativa.EDIPUCRS - Editora Universitária da PUCRS2015-08-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1304610.15448/1980-6523.2014.2.13046Revista Odonto Ciência; Vol. 29 No. 2 (2014); 46-52Revista Odonto Ciência; v. 29 n. 2 (2014); 46-521980-65230102-946010.15448/1980-6523.2014.2reponame: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/13046/13364Copyright (c) 2015 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessBecker, Alex NiederauerOliveira, Elias Pandonor Motcy deHinrichs, RuthVasconcellos, Marcos Antônio ZenWolle, Carlos Frederico Brilhante2015-08-24T20:02:50Zoai:ojs.revistaseletronicas.pucrs.br:article/13046Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2015-08-24T20:02:50Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
