Several theories have been suggested as etiological factors to explain why a tooth deviates from its normal path of eruption to become transposed: interchange in position of the anlage at the very early stage of tooth development [23], genetic control within the dental follicle [20, 21, 24], prolonged retention of the deciduous lateral incisor [25, 26], crowding and inadequate arch length [2].
Differential gene expressions by dental follicle needed for osteoclastogenesis, osteogenesis and pressure from underlying succedaneous teeth are responsible for timely shedding and eruption process of succedaneous teeth (3) and several local, systemic causes including syndromes (Cleidocranial dysplasia, Gardner's syndrome) and metabolic or hormonal diseases have been attributed in literature for impacted and embedded teeth.
