Resumo: The aim of this study was to evaluate the degree of conversion (DC) and cohesive strength (CS) of two conventional   resin cements and a self-adhesive resin cement using different forms of activation. Two conventional dual resin cements (Variolink II and RelyX ARC) and a self-adhesive resin cement were polymerized in three different ways of activation, namely Chemically Activated (CA), Light Activated with Interposition of a resin disc (LI) and Light-Activated (L). The DC was evaluated using Fourier Transformed Infrared Spectroscopy - FTIR (Spectrum 100). In the CS test, the samples were tested until fracture in a universal testing machine (Instron 4411). The mean values obtained in the DC and CS tests were evaluated using two-way analysis of variance (ANOVA) (cement and activation) and Tukey test (p≤0.05). Irrespective of the activation mode, RelyX ARC showed the highest DC values,  RelyX U200, the lowest values, and Variolink II intermediate values. Group L always had higher for DC and CS values than group CA. Among the resin cements, irrespective of the activation mode, there were no differences in CS values. The chemical activation mode of dual resin cements led to lower DC and CS values. RelyX ARC cement had the highest DC values and RelyX U200 cement the lowest values, however, in relation to CS, there were no differences.

RelyX ARC cement had the highest DC values and RelyX U200 cement the lowest values, however, in relation to CS, there were no differences.El objetivo de este estudio fue evaluar el grado de conversión (GC) y la resistencia a la tracción cohesiva (RC) de dos cementos de resina dual convencionales y un cemento de resina autoadhesivo utilizando diferentes formas de activación. Se polimerizaron dos cementos de resina convencionales (Variolink II y RelyX ARC) y un cemento de resina autoadhesivo bajo tres formas de activación diferentes denominadas Químicamente Activadas (QA), Fotoactivadas con Interposición de un disco de resina (FI) y Fotoactivadas (F). La GC se evaluó utilizando espectroscopia infrarroja por transformada de Fourier - FTIR (Spectrum 100). En la prueba RC, las muestras se probaron para fracturar en una máquina de prueba universal (Instron 4411). Los valores medios obtenidos en las pruebas GC y RC se evaluaron mediante análisis de varianza de dos factores (ANOVA) (cemento y activación) y prueba de Tukey (p≤0.05). Independientemente del modo de activación, RelyX ARC obtuvo los valores GC más altos y RelyX U200 los valores más bajos y los valores intermedios Variolink II. El grupo F siempre obtuvo valores más altos que el grupo QA para GC y RC. Entre los cementos de resina, independientemente del modo de activación, no hubo diferencias en los valores de RC. El modo de activación química de los cementos de resina dual condujo a valores de GC y RC más bajos. El cemento RelyX ARC tuvo los valores más altos de GC y el cemento RelyX U200 los valores más bajos, sin embargo, en relación al RC, no hubo diferencias.O objetivo deste estudo foi avaliar o grau de conversão (GC) e a resistência coesiva a tração (RC) de dois cimentos resinosos convencionais duais e um cimento resinoso autoadesivo usando diferentes formas de ativação. Dois cimentos resinosos convencionais (Variolink II e RelyX ARC) e um cimento resinoso autoadesivo foram polimerizados sob três diferentes formas de ativação nomeados como Quimicamente Ativado (QA), Fotoativado com Interposição de um disco de resina (FI) e Fotoativado (F). O GC foi avaliado usando espectroscopia infravermelho transformada de Fourier - FTIR (Spectrum 100). No teste de RC, as amostras foram testadas até a fratura em uma máquina de ensaio universal (Instron 4411). Os valores médios obtidos nos testes de GC e RC foram avaliados utilizando análise de variância (ANOVA) de dois fatores (cimento e ativação) e teste de Tukey (p≤0,05). Independentemente do modo de ativação, RelyX ARC obteve os maiores valores de GC e RelyX U200 os menores valores e o Variolink II valores intermediários. O grupo dos F sempre obtiveram maiores valores que o grupo dos QA para GC e RC. Entre os cimentos resinosos, independentemente do modo de ativação, não existiu diferenças nos valores de RC. O modo ativação química dos cimentos resinosos duais levou a menores valores de GC e RC. O cimento RelyX ARC obteve os maiores valores de GC e o cimento RelyX U200 os menores valores, entretanto, em relação a RC, não houve diferenças.Research, Society and Development2021-07-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1785010.33448/rsd-v10i9.17850Research, Society and Development; Vol. 10 No. 9; e20910917850Research, Society and Development; Vol. 10 Núm. 9; e20910917850Research, Society and Development; v. 10 n. 9; e209109178502525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/17850/16066Copyright (c) 2021 Antonio Carlos Gordilho; Denis Mauro Oliveira Swerts; Milton Edson Miranda; Letícia Cidreira Boaro; William Cunha Brandthttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGordilho, Antonio CarlosSwerts, Denis Mauro Oliveira Miranda, Milton Edson Boaro, Letícia Cidreira Brandt, William Cunha 2021-09-12T14:28:06Zoai:ojs.pkp.sfu.ca:article/17850Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:38:07.231133Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
