Abstract :
Introduction: Composites are rapidly advancing with variations in composition and variable properties that can adapt well with the clinical demand and aesthetic concerns. Studies on pre-heated composites date back to the 2010s. They have recently been added to routine clinical practices. Their properties are much like flowable composites but what about their bond strength?Aim: The aim of the study is to compare the bond strength of pre-heated composite and flowable composite with conventional composite.Materials and Methods: Sixty sound extracted premolars were used. They were divided into three groups with twenty samples in each group. Enamel on the buccal aspect of all the fifteen teeth was removed with diamond saw and dentin was exposed. Bonding agent was applied. Cylindrical moulds of uniform size 5×7 mm were adapted on prepared tooth surface. Group A, the control group was bonded with conventional composite. Group B specimens were bonded with pre-heated composite. Group C specimens were bonded with flowable composite. The bond strength between the tooth and restoration of all sixty samples were measured using universal testing machine.Result: All 3 tested groups showed statistically significant difference in their bond strength (p
