The Study of Water Sorption and Solubility of Differently Formulated Resin Composite Restorative Materials A Comparative Study in vitro

Abstract

Abstract Background: Dental resin composite restorations are widely used to cope with the increased esthetic demands among adults and even children. Its esthetic properties and good clinical use have made it the preferred material for most posterior restorations. One of the main disadvantages of resin composite is the polymerization shrinkage which resulted into microleakage, debonding, secondary caries and postoperative sensitivity. This polymerization shrinkage may cause interfacial debonding between composite resin and walls of the cavity with a consequent gap formation and following secondary caries. To reduce polymerization shrinkage stresses, clinicians have evolved more materials and techniques to solve this problem. One of these techniques is incremental packing of composite. Recently, bulk fill composites had been evolved to decrease voids accompanied by incremental technique and to facilitate use of composite to the clinicians as it is faster and more simple. Aim of the Study: This study was conducted to evaluate the water sorption and solubility behavior of four types of resin composite materials of different filler loading.
