Conclusion the expression of TIMP-1, -2 in human dental pulp cell and tissue is detected, and this provides the basis for further studying on the mechanism of TIMP in dental pulp.

Objective To investigate the expression of BMP-2 in mice incisor enamel organ cells under chronic fluoride exposure and elucidate the mechanism of dental fluorosis.

Objective to simulate the formation of dental calculus by studying the resolution and re-deposition of dental calculus in vitro and to explore the mechanism of dental calculus formation.
