Dentin permeability change according to the process of compomer restoration treatment

Microleakage of restorative materials has been investigated mostly by dye penetration method. Dye penetration method was not quantitative and not measured repeatedly. Fluid filtration method was used to research purpose to understand the effects of various restorative treatments on dentin permeability. The purpose of this study was to evaluate of dentin permeability according to the process of compomer restoration treatment. In this study, C1 V cavities were prepared on buccal surface of thirty extracted human molars. The prepared cavities were etched by 37% phosphoric acid.(omitted)
