Objective: The purpose of this study was to evaluate mechanical and physical properties of three different light-curable resin-based materials (TheraCal LC, Biner LC, and CalciPlus LC) with or without BAG. Material and Methods: 15 cylindrically shaped specimens (n=5) were prepared for contact angle test. The test values (?) were determined with the sessile drop method using three test liquids. 30 acrylic cylindrical blocks were prepared, and holes of (6mmx1mm) were made in the center of the cylinders for shear bond strength test. An adhesive system and a restorative composite material were applied via cylindrically shaped plastic tubes of (2mmx2mm) at the center of the light-curable resin-based material surfaces. The specimens were mounted in a universal testing machine. A crosshead speed of 1 mm/min was applied to each specimen using a knife-edge blade. Results: The highest (74.77°±13.56) and the lowest (35.35°±12.89) contact angle values were recorded for the MB Biner LC group and the CalciPlus LC, respectively. Statistically significant differences observed in contact angle values between the test groups (p<0.05). The surface free energy of Biner LC (?S 36.22) was lower than that of TheraCal LC (?S 44.70) and CalciPlus LC (?S 46.20) (p<0.05). There was no significant difference in shear bond strength values between TheraCal LC and CalciPlus LC (p>0.05). Conclusions: Hydrophilic property of Theracal LC and Calciplus LC resulted in better bonding strength in these materials. The BAG used in Calciplus LC did not adversely affect mechanical and surface properties of the material.
