  • Title: [Neurocristopathic classification of dental abnormalities].
    Author: Couly G, Monteil J.
    Journal: Rev Stomatol Chir Maxillofac; 1982; 83(5):293-8. PubMed ID: 6961503.
    Abstract:
    The neural crest of the vertebrae provides the odontoblasts, which by migrating in the stomodeal epithelium induce in the latter the formation of predamantoblasts (enamel cell). The odontoblasts are then the point of departure of tissue interactions (ectodermal and neurectodermal) which characterise dental organogenesis. An analytical neurocristopathic classification of this organogenesis based upon the developmental properties of the odontoblast is suggested: --abnormalities of formation (anodontism, hypodontism); --abnormalities of migration (ectopism); --abnormalities of cell differentiation and multiplication (hypodontism, microdontism and macrodontism, disturbances in odontogenesis and their combinations, disturbances in amelogenesis). "No odontoblast, no tooth". The dental organ is an indicator of the developmental biological activity of the neural crest as well as its neurulation. Abnormalities in dental organogenesis are of predictive value in terms of other abnormalities of cephalogenesis, those related to the differentiation of the other cells of the neural crest (bone, muscle, cartilage) and those related to the neural tube with which they are territorialised: these are dysneurulations. This classification covers the clinical features of dental abnormalities seen in pediatric stomatology.
