ABSTRACT
With the aim of assessing the performance of Brazilian and imported glass ionomer cements (GIC) with regard to microleakage, 40 primary molars received two standard class II cavity preparations with margins in enamel. Twenty cavities were filled with Brazilian materials (Vidrion® R and Vidrion® R Caps) and the other 20 cavities were filled with imported materials (Fuji® IX and Fuji® IX GPFast capsule). All fillings were performed by a single operator according to the manufacturer's instructions. Teeth were immersed in 0.5 percent methylene blue and half-sectioned. Three independent calibrated examiners assessed microleakage using scores (0-3). Data were submitted to the Kruskal-Wallis statistical test and Wilcoxon analysis. High microleakage indexes were verified for all ionomer cements 59.5 percent of the samples restored with Vidrion® R or Vidrion® R Caps and 83.4 percent of the samples restored with Fuji® IX or Fuji® IX GPFast capsule obtained the maximum score (3). The Brazilian ionomer cements presented less microleakage than imported cements, although this difference was only significant (p=0.003) among the encapsulated materials.
RESUMO
Buscando comparar o desempenho de 2 cimentos de ionômero de vidro (CIV) restauradores convencionais nacionais, mais acessíveis tanto financeiramente quanto por disponibilidade no mercado, ao desempenho de 2 CIV importados frente à microinfiltração, confeccionou-se preparos classe II com término cervical em esmalte em 40 molares decíduos hígidos. Vinte cavidades foram restauradas com os CIV nacionais (Vidrion® R e Vidrion® R Caps) e as demais com os importados (Fuji® IX e Fuji® IX GPFast), por um único operador. Os dentes foram impermeabilizados, imersos em azul de metileno 0,5 por cento e seccionados mesio-distalmente. A microinfiltração foi avaliada por 3 examinadores calibrados, em microscópio estereoscópico, através de escores (0-3). Foram utilizados os testes estatísticos de Kruskall-Wallis e de Wilcoxon. Verificou-se altos índices de microinfiltração para todos os CIV 59,5 por cento das amostras restauradas com Vidrion® R ou Vidrion® R Caps e 83,4 por cento das amostras restauradas com Fuji® IX ou Fuji® IX GPFast obtiveram o escore máximo (3). Os CIV nacionais apresentaram menos microinfiltração que os CIV importados, embora essa diferença só tenha sido significativa (p=0,003) entre os materiais encapsulados.
