Introduction: Vital pulp therapy is a domain of interest in endodontics in recent years to preserve pulp vitality in young permanent teeth, the calcium-based cement is reported to preserve pulp vitality, promote pulp healing and provide a natural substitute for dentine through bioactive stimulation of the dentin-pulpal complex. This study aims to evaluate and compare bonding ability of flowable composite with three different pulp capping material.

Materials and method: Sixty cylindrical acrylic blocks with hole of 3mm in diameter and 1.5 mm in height were prepared and divided randomly into 3 groups containing 20 samples each based on the material used i.e. TheraCal LC ( Group I), Biodentine (Group II), Mineral trioxide aggregate (Group III). Over the pulp capping material, flowable composite was applied by means of plastic cylinder with height and diameter each of 2 mm. Shear bond strength was tested with universal testing machine at crosshead speed of 1mm/min.

Result: Data were analyzed using ANOVA “F” and the post hoc Turkey’s test,Group I (Flowable composite- TheraCal LC) showed highly significant Shear bond strength values in comparison with group I and group II (P<0.001), whereas group II showed significant values in comparison with group III ( P=0.001)

Conclusion: The flowable composite resin to resin component of Theracal LC bond fared better than the flowable resin to calcium silicate based materials MTA and Biodentine when used as pulp capping agent.
