[Bonding of glass ionomer cement to dentin. An in vitro study].

Abstract

It's been studied "in vitro" the influence of the "Smear Layer" on the cement adhesión of the glass ionomer to the dentin. Using phosphoric acid at 37% and poliacrylic in the dentin during short periods of time, the adhesion between the cement and the dentin is improved because the Smear Layer is removed totally in the case of phosphoric acid and partially in the case of polyacrylic acid.
