Odontogenesis

Odontogenesis

Odontogenesis is the formation and development of teeth [ [http://medical.merriam-webster.com/medical/odontogenesis Medical Dictionary] ] . Tooth development can be divided into three overlapping phases. initiation, morphogenesis and histogenesis. During initiation, the oral epithelium folds inwards to form the tooth germs and the site of tooth develoment . Then undifferentiated mesenchymal cells migrates to the site of tooth formation and proliferates to determine the shape of the tooth during the morphogenesis phase. During histogenesis, differentiation of cells proceeds to give rise to the mature dental tissues [B.K.B. Berkovitz, G.R. Holland, B.J. Moxham. Oral Anatomy, Histology and Embryology. Mosby 2002. pg290-363] .

Tooth development is divided into roughly into 5 stages. These are the bud stage, cap stage, bell stage, dentinogenesis and amelogenesis.
