Consequence of an alteration in growth, such as an infolding of the inner enamel epithelium and epithelial sheath of Hertwig
The epithelial antibodies fixation is more intense in two areas: in the enamel knot and in the peripheral parts of inner enamel epithelium. The facial mesenchyme remained weakly positive for both antibodies.
The expressions of Fgf4 and Fgf9 are detected in the inner enamel epithelium (IEE) [66], while the expression of Fgf2 is found in the SR, the expressions of Fgfrl and Fgfr2IIIb in the ameloblasts.
Neural crest cells play an important role in odontogenesis as reflected in the reciprocal induction that occurs between inner enamel epithelium and cells of the dental papilla (which originate from ectomesenchyme, a derivative of neural crest cells).
Its expression is increased in cap stage in enamel knot, inner enamel epithelium and dental papilla whereas Msx2 expressed in odontoblasts, cuspal formation, root initiation.
In both patterns, the outermost cells resemble those of the ameloblastic layer and the inner enamel epithelium. Histologic variations within the epithelial islands give rise to histologic subclasses (e.g., cystic, acanthomatous, granular cell, basal cell, and hemangiomatous).
In the developing tooth, VEGF and VEGFR-2 are expressed in odontoblasts and the inner enamel epithelium and may regulate odontoblast development and the differentiation of inner enamel epithelium to ameloblasts (Aida et al, 2005; Miwa et al, 2008).
Palato gingival grooves, also called palatoradicular grooves or radicular lingual grooves are developmental anomalies in which an infolding of the inner enamel epithelium and Hertwig's epithelial root sheath create a groove that passes from the cingulam and extend varying distances apically on to the root.
In the developing tooth, VEGF and VEGFR-2 are expressed in odontoblasts and the inner enamel epithelium may regulate odontoblast development and the differentiation of inner enamel epithelium to ameloblasts (Aida et al., 2005; Miwa et al., 2008) VEGF expression in pulp fibroblasts and odontoblasts of human teeth is higher in immature than mature permanent teeth, suggesting a role of VEGF in tooth maturation (Wang et al., 2007).
