Nowadays dental patients are seeking a restorative material to their teeth that fulfilled most of the ideal requirements for such use especially aesthetic and functional performance needs. Traditionally composite resin can fulfill these requirements but with the major drawback of shrinkage during polymerization. The shrinkage will be manifested as marginal leakage, cuspal deflection, tooth or restoration fracture, postoperative sensitivity that ends ultimately by failed restoration. The aim of the current work was to pay attention of dental workers to the origin of polymerization shrinkage, its consequences, factors affecting, methods used to measure it, and how can they minimize it for promoting longevity of the restoration.
