Abstract
Purpose: The purpose of this study was to investigate the ability of Mineral trioxide aggregate(MTA) to support osteoclastic differentiation from fetal rat calvarial cell. Methods: In this study, response of IL-6, RANKL, and OPG in fetal rat calvarial cells stimulated with IL-1β on MTA was evaluated by ELISA and RT-PCR. Results: The results were as follows; there was no significant difference between glass and MTA at 5days. In ELISA analysis, Glass group and MTA group showed similar IL-6 expression, Glass+IL-1β group and MTA+IL-1β group showed similar IL-6 expression. In RT-PCR analysis, Glass group and MTA group showed similar IL-6, RANKL, OPG mRNA expression, MTA+IL-1β group and Glass+IL-1β group showed 3 fold increase of IL-6 and RNAKL mRNA expression when compared with MTA group. All groups showed similar OPG mRNA expression. Conclusions: MTA does not suppress cell proliferation and increase the proinflammatory cytokine that induce osteoclastogenesis. Thus, MTA is biocompatible material that could be used in various clinical conditions. (J Korean Acad Periodontol 2009;39:359-365)
