title: Effect of surface penetrating sealant on wear rate of posterior composite resins.
abstract: Although posterior composite resins have been improved considerably, secondary caries and wear continue to be a major concern. Recent studies suggested that microstructural defects such as voids and microcracks contribute to a weakened surface. The purpose of this study was to evaluate the effect of an experimental surface-penetrating sealant on the wear resistance of a posterior composite resin. At the end of 1 year, the rate of wear of the treated restorations was one-half of those not receiving the surface penetrating sealant.
