Sealing depth of Nd:YAG laser on human dentinal tubules.

abstract：INTRODUCTION:It has been reported that integrin-α5 (ITGA5) activity is related to cell proliferation, differentiation, migration, and organ development. However, the involvement of ITGA5 in the biological functions of human dental pulp stem cells (hDPSCs) has not been explored. The aim of this study was to investigate ...
