BACKGROUND: Some of the disadvantages of calcium hydroxide Ca(OH) 2 as pulp-capping material are related to the inflammatory response, and its poor sealing ability. Cyanoacrylate glue was proposed in this study as pulp-capping agent because of its sealing ability, and diprogenta, on the other hand, was proposed because of its anti-microbial and anti-inflammatory effects. The aim of this study is to evaluate and compare the histopathological response of the pulp toward cyanoacrylate and diprogenta in direct pulp capping (DPC). MATERIALS AND METHODS: Cyanoacrylate, diprogenta, and calcium hydroxide were applied on 20 permanent teeth of 6 rabbits divided into four groups, each contains five teeth, as follow: G1: Diprogenta and calcium hydroxide. G2: Cyanoacrylate. G3: Diprogenta and cyanoacrylate. G4: Calcium hydroxide (control group). RESULTS: A remarkable dentin bridge formation was found in all groups. No pulp necrosis was found in any tooth of the four groups. Pathological reactions of the pulp were found in 25%, 40%, 20%, and 100% of groups 1, 2, 3, and 4, respectively. Differences between study and control groups were found statistically significant ( P < 0.05). CONCLUSION: All materials used in this study were biocompatible and suggested to be studied further on human teeth. These materials when used in combination with Ca(OH) 2 , may give better results.
