The enamel organ
, a control gate for calcium influx into the enamel.
This superficial layer can result from the mineralization of an organic matrix under the inner epithelium of the enamel organ
The researchers said that after 3 weeks the cells bundle started to look like a tooth, containing dental pulp, dentin, enamel space and enamel organ
, the BBC reported.
The researchers said that after three weeks the bundle of cells started to resemble a tooth: "The tooth-like structure contained dental pulp, dentin, enamel space and enamel organ
Pindborg himself suggested that the tumor arises as a result of a reduction in enamel epithelium produced by the enamel organ
because it is often associated with an embedded tooth.
An odontogenic cyst is formed by activation of odontogenic cell rests entrapped within the bone tissue or gingival tissue of the jaws, such as the epithelial remains of Malassez, the dental lamina (cell rests of Serres), or the enamel organ
The literature mentions several hypotheses for the etiology of regional odontodysplasia such as trauma, local ischemia, viral infection, vascular defect, irradiation, vitamin deficiency, metabolic and nutritional disorders, Rh incompatibility, local somatic mutation, hyperpyrexia, manifestation of latent virus in the odontogenic epithelium during dental development, genetic mutation of odontoblasts, premature degeneration of the enamel organ
, and idiopathic factors (ALEVA et al.
Coronal resorption is manifested histologically by degeneration of the enamel and dentine of the coronal portion of the tooth, which is ultimately replaced by vascular connective tissue it occurs because of a defect in the enamel organ
of an unerupted tooth [Stafne and Austin, 1945; Blackwood, 1958; Owens et al.
