Evaluation of microleakage in restorations using different brands of Bulk Fill resin
The objective of this work was to evaluate the microleakage in restorations made in class I cavities of Black, using bulk fill flow resins. Ten healthy third molars were selected, which were prepared on the occlusal surface, producing cavities of 3x3x3 mm. Subsequently, the elements were divided into 2 groups (n=5) and restored with two different resin brands. The apices were obliterated and the teeth were waterproofed and then immersed in 50% silver nitrate for 24 h and then in developer for 2 h. The teeth were sectioned, folding the samples, which were evaluated in a 10x stereoscopic magnifying glass. The data were tabulated and analyzed at 5% level of significance, using the Mann-Whitney test. There was no significant difference in microleakage observed between groups 1 and 2.
