Abstract

We present a case of mesiodens identified in a 1-year 9-month-old boy. The patient visited our clinic after receiving a traumatic injury, which caused intrusion of the maxillary right and left primary central incisors. A periapical radiograph revealed no root fractures, though a mesiodens was incidentally found. The intruded teeth naturally moved into their original positions and periodical examinations were scheduled. At 4Y2M, uncommon mesial inclination of the maxillary right primary central incisor was noted. A radiographic examination showed the enlarged dental follicle of the mesiodens, which appeared to cause the inclination, and we planned fenestration when enlargement of the lesion was identified. At 5Y1M, he received another traumatic injury and the maxillary right primary central incisor was exfoliated. At 5Y5M, the mesiodens spontaneously emerged into the oral cavity and a radiographic examination showed prominent rotation of the maxillary right central incisor. Two-thirds of the crown of the mesiodens could be seen at 6Y4M. At 6Y11M, the patient again received a traumatic injury, and intrusion of the maxillary left primary central incisor was observed. At 7Y0M, the mesiodens and maxillary left primary central incisor were extracted under infiltration anesthesia, after which inclination of the axis of the adjacent maxillary right central incisor gradually improved.
