Cavity Liners A cavity liner is used like a cavity varnish to provide a barrier against the passage of irritants from cements or other restorative materials and to reduce the sensitivity of freshly cut dentin. They are usually suspensions of calcium hydroxide in a volatile solvent. Upon the evaporation of the volatile solvent, the liner forms a thin film on the prepared tooth … [Read more...] about Application of Cavity Liners And Varnish Notes
