Aiming to assess the effect of mixing process on microleakage, 40 primary molars were filled with encapsulated glass ionomer cements (GICs) (Vidrion,RCaps and Fuji,IXGPFAST) or with GICs stored in bottles (Vidrion,R and Fuji,IX). Dye penetration was assessed using scores. Encapsulation and mechanical mixing have reduced significantly marginal microleakage levels in class II restorations performed with conventional GICs if compared to the values obtained by their bottled correspondents (p=0,000).

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% 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% of the samples restored with Vidrion® R or Vidrion® R Caps and 83.4% 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.
