An in vitro comparative evaluation of physical properties of four different types of core materials.

Introduction: Compressive and tensile stresses of core materials are important properties because cores usually replace a large bulk of tooth structure and must resist multidirectional masticatory forces for many years.

Material And Methods: The present study was undertaken to find out the best core build up material with respect to their physical properties among resin-based composites. Individual compressive, tensile, and flexural strength of fiber-reinforced dual cure resin core build up material, silorane-based composite resin, and dual curing composite for core build up with silver amalgam core was used as control were evaluated and compared using universal testing machine.
