Context: Nowadays, dentists use tooth-colored materials extensively, but the bond strength of these materials with teeth is crucial to determine their long-span durability. As a result, the bond strength of these materials must be assessed. Aims: This study aimed to compare the push-out bond strength of alkasite restorative material and bulk-fill composite when used with a universal adhesive system. Settings and Design: In vitro study to determine the push-out bond strength with a universal testing machine. Subjects and Methods: Forty extracted mandibular molars were taken and their occlusal surface was wet grounded with silicon carbide paper so that a smooth dentin surface was obtained. Class I cavities were prepared with a template to standardize the size of the preparation. Teeth were divided into Group I and Group II of 20 teeth each. Alkasite restorative material was used in Group I, and nanohybrid bulk-fill composite was used in Group II. Restored samples were sliced into 2 mm thick sections and examined for push-out bond strength. Results: Push-out bond strength of Cention-N was 201.25 and the composite was 163.69, and the results were statistically significant (P = 0.017). Statistical Analysis Used: Unpaired t-test. Conclusions: It was concluded that alkasite material had more push-out bond strength than bulk-fill composite when used with a universal adhesive system.
