Resumo: | Objective: To assess, in vitro, the accuracy of MiniApex® for electronic working length (EWL) determination during three stages of root canal treatment/retreatment: EWL-1 (during treatment), EWL-2 (after filling removal), and EWL-3 (after reinstrumentation).Methods: EWL was determined when the MiniApex® display showed the green light at the ‘0.5’ mark and compared with radiographic findings. Results were classified as accurate when the file tip was located in a range of (1) 0.5 to 1.0 mm and (2) 0.5 to 2.0 mm from the radiographic apex, and as inaccurate when the file tip was outside that range of values. Means were compared between groups considering all values and only accurate measurements, for both tolerance limits.Results: MiniApex® was highly accurate at the larger tolerance range (0.5 2.0mm): 82.3% (EWL-1), 88.2% (EWL-2), and 91.1% (EWL-3). During root canal retreatment, EWL-3 provided more accurate measurements than EWL-2, but without statistical difference (p>0.05). There was no statistical difference (p>0.05) when only accurate measurements were evaluated.Conclusion: MiniApex® was highly accurate to determine the location of the instrument tip at 0.5 to 2.0mm from the radiographic apex during treatment and retreatment (EWL-2 and EWL-3). |

There was no statistical difference (p>0.05) when only accurate measurements were evaluated.Conclusion: MiniApex® was highly accurate to determine the location of the instrument tip at 0.5 to 2.0mm from the radiographic apex during treatment and retreatment (EWL-2 and EWL-3).Objetivo: Avaliar, in vitro, a precisão do localizador MiniApex® na determinação do comprimento de trabalho eletrônico (CTE) em três estágios do tratamento/retratamento de canais: CTE-1 (durante o tratamento), CTE-2 (após a remoção da obturação) e CTE-3 (após o repreparo do canal radicular).Métodos: O CTE foi definido quando o display do MiniApex® mostrou luz verde na marca de ‘0,5’, e foi confirmado radiograficamente. Os resultados foram classificados como precisos quando a ponta do instrumento se localizava a (1) 0,5-1,0 mm ou a (2) 0,5-2,0 mm do ápice radiográfico, e como imprecisos quando a mensuração ficava fora desses valores. As médias foram comparadas entre os grupos considerando todos os valores e apenas valores precisos, para ambos os limites de tolerância.Resultados: O MiniApex® foi efetivo considerando-se o limite maior de tolerância (0,5-2,0mm): 82,3% (CTE-1), 88,2% (CTE-2) e 91,1% (CTE-3). Durante o retratamento, CTE-3 demonstrou mensurações mais precisas do que CTE-2, porém sem diferença estatística (p>0,05). Não foram observadas diferenças estatísticas (p>0,05) entre as mensurações precisas.Conclusão: O MiniApex® foi confiável na determinação do comprimento de trabalho considerando as medidas compreendidas no intervalo de 0,5-2,00mm do ápice radiográfico durante o tratamento e retratamento de canal (CTE-2 e CTE-3).EDIPUCRS - Editora Universitária da PUCRS2016-01-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1502310.15448/1980-6523.2015.4.15023Revista Odonto Ciência; Vol. 30 No. 4 (2015); 138-142Revista Odonto Ciência; v. 30 n. 4 (2015); 138-1421980-65230102-946010.15448/1980-6523.2015.4reponame: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/15023/14430Copyright (c) 2016 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessLassen, CauêDotto, Ronise FerreiraSantos, Paulo Silva dosWagner, Márcia HelenaGrazziotin-Soares, RenataBarletta, Fernando Branco2016-06-16T13:45:46Zoai:ojs.revistaseletronicas.pucrs.br:article/15023Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2016-06-16T13:45:46Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
