Abstract
The purpose of this in vitro study was to evaluate and compare the degree of microleakage of the enamel-sealants interface when used four different materials. Analysis of the penetration of sealing materials shows that they adhere different to the enamel and the characteristics of resin composite materials used in clinical practice as sealants, influencing dental material penetration to the surface once the viscosity of the inorganic filler.
