Transposition is a unique and extreme form of ectopic eruption in which a permanent tooth develops and erupts in the position which is normally occupied by other permanent teeth. Tooth transpositions are rare and they can be complete or incomplete. The aetiology of transposition is still obscure. Various populations have been studied, to determine the prevalence of tooth transpositions. 20% of the transpositions which occur on the maxillary arch involve the canine and the lateral incisor. Although they are rare, transpositions may involve the maxillary lateral and central incisors. Among all transpositions, Mandibular Lateral Incisor-Canine (Mn.I2.C) is the rarest, with a prevalence rate of 0.03%. Although various reports have been published on tooth transpositions, very few have noted the agenesis of teeth, particularly Mn.I2.C and its management. We are reporting a rare clinical case with associated hypodontia.
