Tooth development – Histology and Embryology for Dental …
WEBThis is known as the root formation theory. To say this causes tooth eruption, it has to be both necessary and sufficient (a phrase commonly used in biological research). Because root-less teeth can erupt suggests root growth is not necessary for eruption.
Cellular and molecular mechanisms of tooth root development
WEBFeb 1, 2017 · The formation of a functional root depends on epithelial-mesenchymal interactions and integration of the root with the jaw bone, blood supply and nerve innervations. The root development process therefore offers an attractive model for investigating organogenesis.

WEBJan 9, 2015 · After the crown of the tooth is formed, development of the root portion begins. At the cervical border of the enamel (the cervix of the crown), cementum starts to form as a root covering of the dentin. The cementum is similar in some ways to bone tissue and covers the root of the tooth in a thin layer.

WEBJan 1, 2020 · The upper portion of the mammalian tooth, which is exposed to the oral cavity, is known as the dental crown, and the portion buried inside the jaw bone is called the dental root. Based on the crown/root proportion, mammalian teeth can be divided into four main types: brachydont, mesodont, hypsodont and hypselodont.
Signaling Pathways Critical for Tooth Root Formation - PMC
WEBJun 30, 2017 · Overall, the TGF-β signaling is important not only for postnatal tooth root formation but also for continuous crown dentin formation without changing the NFIC signal pathway. In contrast, BMP signaling is more specific for the root formation in which NFIC is likely a key downstream molecule for root elongation.
