The cause of DE is still unclear. There is literature indicating that DE is an isolated anomaly. During the bell stage of tooth formation, DE may occur as a result of an unusual growth and folding of the inner enamel epithelium and ectomesenchymal cells of dental papilla into the stellate reticulum of the enamel organ.
