Resumo: | The present study had as objective to evaluate the resistance to torsion fracture of two instrumentation systems based on different motion cinematics: alternating movement of the system TF Adaptive and the rotary movement of the system HYFLEX CM. For this 15 TF Adaptive instruments were used to 27 mm in length, with the following dimensions: 20/.04, 25/.06, 35/04 and 30 Hyflex CM instruments to 25 mm in length, with the following dimensions: 25/.08, 20/.04, 25/04, 20/.06 , 30/.04 and 40/.04. The instruments were evaluated prior to your use and after two, four, six and eight use in simulated acrylic resin canals. These canals were standardized and their curvature was 35 degrees and their final length 18 mm, being this point reached at the end of the instrumentation in both systems. The variable in question was measured in degrees until the time of instrument fracture, obtained through a modified Troptômetro. The values registered at the time of fracture, for each instrument, were submitted to statistical analysis using the Wilcoxon test, Mann-Whitney U Test for comparison between the two systems of instrumentation (p ≥ 0.05). The results showed that both instruments did not show differences when evaluated without any use, after two uses, four uses, six uses and finally eight uses (p ≥ 0.05). It was concluded that TF Adaptive systems and Hyflex CM showed similarity as resistance to torsion fracture. |

Para ello se utilizaron 15 instrumentos TF Adaptive de 27 mm de longitud, con las siguientes características: 20 / .04, 25 / .06, 35 / .04 y 30 instrumentos Hyflex CM de 25 mm de longitud, con las siguientes características: 25 /.08, 20 / .04, 25 / .04, 20 / .06, 30 / .04 y 40 / .04. Los instrumentos fueron evaluados antes de su uso y después de dos, cuatro, seis y ocho usos en canales simulados en bloques de resina acrílica estandarizada cuya curvatura del canal fue de 35 grados y su longitud final fue de 18 mm, alcanzándose este punto al final de la instrumentación. en ambos sistemas empleados. La variable en cuestión fue la medición en grados hasta el momento de la fractura del instrumento, obtenida mediante un Troptómetro modificado. Los valores registrados en el momento de la fractura, para cada instrumento, se sometieron a análisis estadístico mediante la prueba U de Wilcoxon Mann-Withney para comparar los dos sistemas de instrumentación. Los resultados mostraron que ambos instrumentos no presentaron diferencias al ser evaluados sin ningún uso, luego de dos usos, cuatro usos, seis usos y finalmente ocho usos (p ≥ 0.05). Se concluyó que los sistemas TF Adaptive e Hyflex CM eran similares en términos de resistencia a la fractura por torsión.O presente estudo teve como objetivo avaliar a resistência à fratura por torção de dois sistemas de instrumentação baseados em diferentes cinemáticas de movimento: o movimento alternado do sistema TF Adaptive e o movimento rotatório do sistema Hyflex CM.

Os instrumentos foram avaliados anteriormente ao seu uso e após dois, quatro, seis e oito usos em canais simulados em blocos de resina acrílica padronizados cuja curvatura do canal era de 35 graus e seu comprimento final de 18 mm, sendo esse ponto alcançado ao final da instrumentação em ambos os sistemas empregados. A variável em questão foi a medida em graus até o momento da fratura do instrumento, obtida por meio de um Troptômetro modificado. Os valores registrados no momento da fratura, para cada instrumento, foram submetidos à análise estatística utilizando o teste de Wilcoxon Mann-Withney U Test para a comparação entre os dois sistemas de instrumentação. Os resultados mostraram que ambos os instrumentos não apresentaram diferenças quando avaliados sem nenhum uso, após dois usos, quatro usos, seis usos e por fim oito usos (p ≥ 0.05). Concluiu-se que os sistemas TF Adaptive e Hyflex CM apresentaram similaridade quanto a resistência à fratura por torção.Research, Society and Development2021-10-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2160410.33448/rsd-v10i14.21604Research, Society and Development; Vol. 10 No. 14; e28101421604Research, Society and Development; Vol. 10 Núm. 14; e28101421604Research, Society and Development; v. 10 n. 14; e281014216042525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/21604/19339Copyright (c) 2021 Rodrigo Zuccolotto Ferraz Caselli; Cesar Augusto Perini Rosas; Ana Grasiela Limoeiro; Rina Andrea Pelegrine; Carlos Eduardo Fontana; Emílio Henrique Rocha Gonçalves Ferreira; Rodrigo Casasanta França; Marcelo dos Santos; Carlos Eduardo da Silveira Buenohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCaselli, Rodrigo Zuccolotto FerrazRosas, Cesar Augusto PeriniLimoeiro, Ana Grasiela Pelegrine, Rina Andrea Fontana, Carlos EduardoFerreira, Emílio Henrique Rocha GonçalvesFrança, Rodrigo Casasanta Santos, Marcelo dos Bueno, Carlos Eduardo da Silveira2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/21604Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:59.315487Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
