Effect of MTAD on the differentiation of osteoblast-like cells

J Endod. 2010 Feb;36(2):260-3. doi: 10.1016/j.joen.2009.11.002.

Abstract

Introduction: The aim of the present study was to investigate the effect of MTAD on the differentiation of osteoblast-like cells.

Methods: The cell viability assay was performed to evaluate the cytotoxicity of MTAD on MC3T3-E1 and periodontal ligament cells at the various concentrations. The bone sialoprotein (BSP) gene expression was also examined by real-time polymerase chain reaction.

Results: MTAD exhibited a lower cytotoxicity compared with other intracanal irrigants and medication. The MC3T3-E1 cells treated with H2O2 showed a decrease in the alkaline phosphatase (ALP) activity by 40% on day 14 compared with the control group at the concentration of 50 microg/mlL. No significant difference in the ALP activity was observed between MTAD and control group. Furthermore, MTAD and Ca(OH)2 paste did not change in BSP gene expression in MC3T3-E1 cells on day 21.

Conclusions: These results suggested that MTAD is a less cytotoxic irrigant and does not affect differentiation into osteoblasts compared with other intracanal irrigants, such as H2O2, NaOCl, ethylenediaminetetraacetic acid, and chlorhexidine.
