WebTooth development is a complex process that involves a series of reciprocal interactions between the epithelium and the mesenchyme, similar to the development of other ectodermal organs. These interactions are mediated by major signaling pathways, members of which act reiteratively at diverse stages during the development of these organs. WebWhile osteoblasts, which are typical hard-tissue-forming cells, are generated from mesenchymal stem cells during normal and pathological bone metabolism, the induction of odontoblasts only occurs once during tooth development, and odontoblasts survive throughout the lives of healthy teeth.
