The aim of the present study was to evaluate the effects of MTA and CS cements on inflammatory reactions in primary cultured human dental pulp cells. Methods: The mitochondrial colorimetric assay was used to evaluate pulp cell survival rates. Fluorescent immunohistochemistry was used to observe focal adhesion kinase (FAK) and cyclooxygenase-2 (COX-2) distributions in the cells. Reverse transcription-polymerase chain reaction was used to assess COX-2 expression. Results: The results showed that MTA and CS are biocompatible with pulp cells (P > .05). FAK was well-distributed in pulp cells in contact with both cements. Both MTA and CS cements induced pulp cell inflammation as evidenced by increased COX-2 expression. Conclusions: The present study demonstrated that MTA and CS cements are biocompatible with primary cultured pulp cells. Both cements can induce inflammatory COX-2 expression in the pulp cells.4enjournal article
