Resumo: | OBJECTIVE: to evaluated the influence of two types of low-fusing porcelain glaze application on the surface of a zirconia ceramics stabilized by yttrium (Y-TZP).METHODS: Y-TZP specimens were divided into five groups (n=5) according the surface treatments: control (CO), no treatment was performed; application of a thin low-fusing porcelain glass layer by the powder/liquid technique (GPL); GPL followed by 10% hydrofluoric acid (HF) etching (GPL-HF); glaze spray application (GS); GS followed by 10% HF etching (GS-HF). Roughness measurements contact angle, x-ray diffraction, energy-dispersive spectroscopy (EDS) and scanning electron microscope (SEM) analysis were performed.RESULTS: ANOVA and Tukey tests revealed that GPL had significantly lower contact angle values than the other groups (GPL:50.31º; GPL-HF: 72.73º; GS-HF: 81.73º; CO: 96.48º; GS:101.30º; p=0.001). GPL-HF presented a significant higher roughness (Ra/Rq: 2658.0/3367.0 ηm; p=0.001) than the other groups (GPL: 872.1/1162.0 ηm; GS-HF: 383.0/603.6 ηm; GS: 303.4/391.3 ηm; CO:263.4/339.1 ηm). The X-ray diffraction analysis just tetragonal phase in all groups. EDS and SEM analysis show a highest amount of silica on GPL and GPL-HF surface.CONCLUSION: the application of the low-fusing porcelain glaze by the powder/liquid technique followed by the HF etching promoted a better surface to micromechanical and chemical adhesion. |

Análise do ângulo de contato, aferição de rugosidade, difração de raios X, espectroscopia dispersiva de energia (EDS) e microscópio eletrônico de varredura (SEM) foram realizados.RESULTADOS: Os exames ANOVA e Tukey revelaram que a GPL apresentou valores de ângulo de contato significativamente menores que os demais grupos (GPL: 50,31º; GPL-HF: 72,73º; GS-HF: 81,73º; CO: 96,48º; GS: 101,30º; p=0,001). GPL-HF apresentou uma rugosidade significativamente maior (Ra/Rq: 2658.0/3367.0 ηm; p=0,001) do que os outros grupos (GPL: 872.1/1162.0 ηm; GS-HF: 383.0/603.6 ηm; GS: 303.4/391.3 ηm; CO: 263.4/339.1 ηm). A análise de difracção de raios X apenas a fase tetragonal em todos os grupos. A análise EDS e SEM mostra uma quantidade grande de sílica na superfície GPL e GPL-HF.CONCLUSÃO: A aplicação do glaze pela técnica de pó/líquido seguida do condicionamento com HF promoveu uma melhor superfície para a adesão micromecânica e química.EDIPUCRS - Editora Universitária da PUCRS2018-07-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlelaboratory researchapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/2874910.15448/1980-6523.2017.4.28749Revista Odonto Ciência; Vol. 32 No. 4 (2017); 174-179Revista Odonto Ciência; v. 32 n. 4 (2017); 174-1791980-65230102-946010.15448/1980-6523.2017.4reponame: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/28749/17008Copyright (c) 2018 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessMiranda, Jean SoaresMalta, Natália Velosode Carvalho, Ronaldo Luís AlmeidaSouza, Rodrigo Othávio de Assunção eMachado, João Paulo BarrosLeite, Fabíola Pessôa Pereira2018-07-25T17:42:36Zoai:ojs.revistaseletronicas.pucrs.br:article/28749Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2018-07-25T17:42:36Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
