GaAlAs Diode Laser-induced Mineralized Tissue Formation in Dentin/Pulp Complex: A Review

Abstract

GaAlAs diode laser (810 nm) is known to induce mineralized tissue formation in dentin/pulp complex, and thus may contribute to the improvement in the predictability of vital pulp therapy. The mineralized tissue formation may involve the reparative process that takes place after injury of the dental pulp, whereas the detailed mechnisms remain to be elucidated. Thus, 〒 the authors examined the dynamics of cells expressing an odontoblast differentiation marker (heat-shock protein 25) and analyzed the expression of non-collagenous matrix proteins in diode laser-irradiated rat molars. The purpose of this paper is to review our experimental findings and discuss mechanisms behind the diode laser-induced mineralized tissue formation in dentin/ pulp complex.
