Etiology of Various Dental Developmental Anomalies -Review of Literature

The development of the tooth involves many complex biological processes, including epithelialmesenchymal interactions, differentiation, morphogenesis, fi brillogenesis and mineralization. After 37 days of development, a continuous band of thickened epithelium forms around the mouth in presumptive upper and lower jaws from the fusion of separate plates of thickened epithelium–primary epithelial band and gives rise to vestibular lamina and dental lamina [1].
