POSTOPERATIVE PAIN FOLLOWING RESTORATION WITH SONIC FILL VERSUS COMPOSITE RESIN IN CHILDREN WITH DEEP CARIOUS FIRST PERMANENT MOLAR

For many years, composite resin restorations have been considered an acceptable treatment choice for anterior applications. Recent advances in composite resin mechanical properties and improved adhesive systems have broadened the application of these materials to include the restoration of posterior teeth.4 However, it is still generally accepted that posterior composite resin restorations have limitations and that there is no ideal material available.5 A volumetric shrinkage occurs when a composite resin material is cured.1 New nanohybrid composite activated by sonic energy has been recently introduced as a single- step, bulk-fill restorative material.
