Cavity liners have traditionally been used in direct and indirect restorations for purposes such as promoting reparative dentin and neutralizing acids.
Today, liners are used when resin composites are used as the restorative materials on the posterior teeth, but for a different reason. Clinically, liners are considered to decrease sensitivity and wet the cavity better than restorative composites because of their flowability, adaptation to the dentinal surface, and adhesion.
As bonding systems and composite materials continue to improve and become better understood, so do the techniques for placing composites.
