The viscosity of phosphoric acid etchants for enamel and dentin may be increased by the addition of silica. This in vitro study investigated the effect of a silica-containing 10% phosphoric acid gel on the bond strength of composite resin to dentin as compared to a 10% phosphoric acid gel without silica, using 20 extracted human molars. The results indicated that the etchant containing submicron silica provided higher bond strengths than the etchant without a silica constituent. The learning objective of this article is to provide the findings of the study for the clinicians.
