Uncommon true isolated macrodontia of a maxillary tooth

Macrodontia is a rare dental anomaly which consists on the presence of any tooth or teeth larger than the average. In the present report the case of a child with an uncommon true isolated macrodontia of a maxillary central incisor is presented. The maxillary left central incisor was considered a macrodontic tooth since its mesiodistal crown dimension was 12.41 mm while the mesiodistal crown dimension of the maxillary right central incisor was 10.06 mm. The radiographic examination confirmed an enlarged maxillary left central incisor and a normal developing dentition. The patient did not report esthetic complaints, however, due the presence of anterior open bite and crowding, he was referred to orthodontic clinic. Thus, it must be point out the importance of the radiographic diagnosis to support the clinical findings, helping to plan and provide better treatment for the patient.
