Etiology of Various Dental Developmental Anomalies -Review of Literature

Abstract

The development of the tooth involves many complex biological processes, including epithelial-mesenchymal interactions, differentiation, morphogenesis, fibrillogenesis 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]. A series of factors influence the normal development of the occlusion, interfering with the correct alignment of teeth and harmonic relationship with the adjacent and antagonistic elements [2]. The most spectacular period of development of the human body takes place in utero and during this period various disturbances may occur, producing changes which are congenital but not always inherited. The explanation for the tendency of the person to inherit certain features or characteristics from his parents is based upon the monumental principle observations of Mendel, who gave two principles on which the transmission of characteristics was based [3].
