Abstract With the increase in esthetic awareness and the widespread use of adhesive techniques, a resin composite has become the material of choice for anterior and posterior restorations. In spite of its advantages, polymerization shrinkage and the resulting stress are still a concern for clinicians. The shrinkage stress may cause cusp deflection, interfacial debonding or enamel cracks, leading to microleakage, post-operative sensitivity and secondary caries.
