Abstract:

Tooth eruption undergoes a series of sophisticated physiological procedures that involve the formation and resorption of alveolar bone. Previous studies indicated that dental follicle(DF) plays a key role in tooth eruption by modulating bone remodeling around the tooth. It secretes multiple chemokines to recruit monocytes and facilitate the differentiation and maturation of osteoclasts via RANKL/RANK/OPG axis, eventually leading to the resorption of the coronal alveolar bone to form eruptive pathway. Simultaneously, dental follicle is enriched with dental follicle cells, whose osteogenic activity are subject to TGF-β/BMP and WNT signaling pathway as well as epigenetic regulation, which in turn promotes the formation of basal alveolar bone and provides motive force for tooth eruption. In recent years, studieson bone remodeling mechanisms of tooth eruption have made further progress, and this review elaborates the cellular and molecular mechanisms involved in bone remodeling by dental follicle during tooth eruption.
