Abstract
Aim: Assessment of shear bond strength of different pulp capping materials (chemical and light cured Dycal, Biodentine and TheraCal LC) to composite resin restoration. Materials and Methods: 40 acrylic blocks with cylinder holes measuring 5×2 mm3 each were prepared. The holes were filled with pulp capping materials, on each pulp capping material composite resin restoration was applied. Then shear bond strength was evaluated by the universal testing device. Analysis of data was done by one way "ANOVA" and "post hoc Tukey’s test". Results: shear bond strengths of different pulp capping materials were significantly different (P<0.05). The lowest bond strength was revealed by chemical cured dycal while the highest bond strength was revealed by light cured dycal. Conclusion: Type of pulp capping materials plays an important role in achieving proper bond to composite resin restoration.
