Varnish for protecting a tooth surface.

摘要

A tooth is restored by forming a temporary coating of a polymer on a tooth surface so as to protect a healthy tooth surface against erosion by an acid etching agent, then subjecting only the wall of the tooth cavity to the acid etching treatment, and subsequently filling and restoring the tooth cavity with a dental filling material. The varnish comprises a polymer having vinyl chloride and vinyl acetate as main constituent monomer units dissolved in a solvent for forming the polymer coat.
