The smear layer tissue created by cutting a tooth. It varies in thickness, roughness, density and degree of attachment andoccludes tubules and reduces the dental permeabilita. Dentin adhesivesystems can react with intertubular and peritubular dentin only when this smear layer is removed or when ...
