    We prepared experimental pulp capping materials those were consist of Mineral Trioxide Aggregate (MTA) and a hydrophilic monomer in order to develop an adhesive pulp capping material. The purpose of this study was to investigate dentin shear bond strengths and releasing of calcium ions of those experimental or commercial pulp capping materials.

    As a result, two experimental pulp capping materials had excellent marginal sealing property than commercial pulp capping agents, even higher shear bond strengths. In a comparison between experimental pulp capping agents having different composition ratios of monomer and MTA, the group with a relatively large amount of monomer showed higher shear bond strengths. The group with a large amount of MTA showed no penetration of dye in the dye penetration canal and releasing amount of calcium ion was higher than the group with a small amount of MTA. The composition ratio of MTA and a hydrophilic monomer may affect the basic property of the pulp capping material.

    More research is required to determine the ideal composition ratio of MTA/monomer to develop an adhesive pulp capping material that has excellent dentin marginal sealing property and exhibits highest adhesive strength.
