Abstract

Introduction: Mineral trioxide aggregate (MTA) is widely used as a pulp capping material. Recently, a MTA-derived fast-setting pozzolan cement (Endocem; Maruchi, Wonju, Korea) was introduced in the endodontic field. Our aim in this study was to investigate the odontogenic effects of this cement in vitro and in vivo.
Methods: Human dental pulp cells (hDPCs) were cultured, and the effects of Endocem and a previously marketed MTA (ProRoot; Dentsply, Tulsa, OK) on biocompatibility were evaluated by assessing cell morphology and performing a cell viability test. Chemical
composition of each material was analyzed by energy-dispersive X-ray spectroscopic analysis. Odontoblastic
differentiation was analyzed by alkaline phosphatase activity and alizarin red S staining. The __EXPRESSION__ of odontogenic-related markers, namely dentin sialophosphoprotein, dentin matrix protein 1, and osteonectin, was evaluated by real-time polymerase chain reaction, Western blotting, and immunofluorescence analysis. Pinpoint pulp exposures were made on rat teeth and then capped with ProRoot or Endocem. After 4 weeks, reparative tertiary dentin formation and inflammatory responses were investigated histologically.
Results: The biocompatibility of Endocem was similar to that of ProRoot. Energy-dispersive X-ray spectroscopic
analysis showed that ProRoot and Endocem contained similar elemental constituents such as calcium, oxygen, and silicon. Alkaline phosphatase activity and mineralized nodule formation increased in ProRootand Endocem-treated cells compared with medium only–treated cells in the control group (P < .05). The __EXPRESSION__ of odontogenic-related markers was significantly higher in the ProRoot- and Endocem-treated groups than the control group (P < .05), but there was no significant difference in the __EXPRESSION__ of these markers between the 2 experimental groups (P > .05).
Four weeks after the pulp capping procedure, continuous tertiary dentin had formed directly underneath the capping materials and the pulp exposure area in all samples in the 2 treated groups. Furthermore, most specimens
either had no inflammation or minor pulpal inflammation.
Conclusions: Our results indicate that ProRoot and Endocem have similar biocompatibility and odontogenic effects. Therefore, Endocem is as effective a pulp capping material as ProRoot.
