Background: Optimal flowability and adhesiveness are critical properties of root canal sealers to ensure effective sealing and prevention of microleakage. Calcium hydroxide-based sealers such as Calapex and Sealapex are widely used due to their biological and physicochemical properties. Aim: To evaluate and compare the flowability and adhesiveness (push-out bond strength to dentin) of two calcium hydroxide-based root canal sealers: Calapex (Prevest DenPro, India) and Sealapex (Kerr, USA). Materials and Methods: Forty extracted single-rooted human teeth were prepared and randomly divided into two groups (n=20). Group 1: Calapex; Group 2: Sealapex. Flowability was assessed using ISO 6876 standards. Adhesiveness was evaluated using push-out bond strength testing with a universal testing machine. Failure modes were analyzed under stereomicroscopy. Statistical analysis was performed using independent t-test (p<0.05). Results: Both sealers demonstrated flowability within ISO recommended limits, with no statistically significant difference between groups (p>0.05). Push-out bond strength values showed comparable adhesion to dentin in both groups, indicating clinically acceptable adhesion. Predominantly mixed failure patterns were observed. Conclusion: Both Calapex and Sealapex exhibited optimal flow and adequate adhesiveness to root dentin, supporting their clinical use as reliable calcium hydroxide-based sealers.
