description	The purpose of this study was to evaluate the influence of the chemical polishing, when compared to the mechanical polish, in the sorption, solubility and microhardness of a heat-polymerizable acrylic resin. The heatactivated acrylic resin used was Clássico (Art. Odontológicos Clássico Ltda., S.P.). The properties of sorption and the solubility were tested in accordance with International Organization for Standartization (ISO) specification n. 1567, making 20 samples in the format of disks, divided aleatory in two groups, where the first group received lhe mechanical polish with abrasive pastes, and the second, the chemical polish during IOS, in the chemical polisher PQ 9000 (série 4868-2, Termotron do Brasil Ltda., Piracicaba, SP). The samples were maintained in a desiccator with silica gel, at 37 DC, until the moment they reached constant mass (M1), obtained in a scale with resolution of 0,0001g. The samples were submerged in distilled water, at 37 Uc, for 7 days, when it was Obtained new mass value (M2). The difference between M1 and M2 divided by the volume Of each sample resulted in the sorption. The samples were desiccated again until they reach constant mass (M3). The difference between M1 and M3 divided by the volume of each sample resulted in the solubility Of the same ones. For the Knoop microhardness measurement, were made 20 specimens of acrylic resin, of which 10 samples received the mechanical polish and the others, the chemical polish. The Knoop microhardness test was made with a NU Research Microscope (VEB Carl Zeiss JENAGermany). The results indicated that the technique of the chemical polish is acceptable when considered the sorption property, even so unviable with the solubility property, in accordance with the specification n.1567 of ISO. The chemical polish also reduced significantly the superficial microhardness of the acrylic resin, which consequences can interfere in the clinical performance of the material.

Os ensaios foram realizados utìizando-se a resina acrílica de termopolimerização da marca Clássico (Art. Odontológicos Clássico Ltda.,S.P.). A sorpção e solubilidade foram realizadas conforme a especificação nº1567 da International Organization for Standartization (ISO), confeccionando-se 20 corpos de prova no formato de discos, divididos aleatoriamente em dois grupos, onde o primeiro recebeu o polimento mecânico com pastas abrasivas, e o segundo, o polimento químico durante 10s, na polidora química PQ 9000 (série 4868-2, Termotron do Brasil Ltda., Piracicaba, SP). Os corpos de prova foram mantidos em um dissecador com sílica gel, a 37ºC, até que apresentassem massa constante (MI), obtida numa balança com resolução de 0,0001g. As amostras foram imersas em água destilada a 37ºC, durante 7 dias, e novamente pesadas (M2). A diferença ente M2 e Ml em relação ao volume de cada corpo de prova resultou na sorpção. A seguir, os corpos de prova foram novamente dissecados até a obtenção de massa constante (M3). A diferença entre Ml e M3 em relação ao volume de cada corpo de prova resultou na solubilidade dos mesmos. Para a execução do ensaio de microdureza Knoop foram confeccionados 20 corpos de prova de resina acrílica, dos quais 10 amostras receberam o polimento mecânico e as demais, o polimento químico. A mensuração da microdureza foi realizada no NU Research Microscope (VEB Carl Zeiss JENA- Germany). Os resultados indicaram que a técnica de polimento químico é aceitável quando considerada a propriedade de sorpção, porém inviável quanto à propriedade de solubilidade, de acordo com a especificação nº1567 da ISO. O polimento químico também reduziu significativamente a dureza superficial da resina acrílica, cujas consequências poderão interferir no desempenho clínico do material.UFRGS2021-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufrgs.br/index.php/RevistadaFaculdadeOdontologia/article/view/11027310.22456/2177-0018.110273Revista da Faculdade de Odontologia de Porto Alegre; Vol. 41 No. 1 (2000); 8-13Revista da Faculdade de Odontologia de Porto Alegre; v. 41 n. 1 (2000); 8-132177-00180566-1854reponame:Revista da Faculdade de Odontologia de Porto Alegre (Online)instname:Universidade Federal do Rio Grande do Sul (UFRGS)instacron:UFRGSporhttps://seer.ufrgs.br/index.php/RevistadaFaculdadeOdontologia/article/view/110273/60036Copyright (c) 2020 Susana Maria Werner Samuel, Catia Rubinstein Selistreinfo:eu-repo/semantics/openAccessSamuel, Susana Maria WernerSelistre, Catia Rubinstein2021-12-01T14:21:20Zoai:seer.ufrgs.br:article/110273Revistahttps://seer.ufrgs.br/index.php/RevistadaFaculdadeOdontologia/indexPUBhttps://seer.ufrgs.br/index.php/RevistadaFaculdadeOdontologia/oairevistaodonto@ufrgs.br2177-00180566-1854opendoar:2021-12-01T14:21:20Revista da Faculdade de Odontologia de Porto Alegre (Online) - Universidade Federal do Rio Grande do Sul (UFRGS)false
