The results indicated that treatment of the cells with sodium fluoride 10^(-7-10^(-3)molL^(-1) up-regulated the expression of osteocalcin gene in a dose-dependent manner. Furthermore, 5×10^(-4) molL^(-1) sodium fluoride treatment showed a maximal stimulation, which was almost 30 times higher than the control.
