Mesiodens surgery at deciduous and permanent dentition

ABSTRACT

Introduction and Objective:To report a rare case of a patient who presented two mesiodens and the treatment performed at two moments. Case report: A 7 year-old male patient reported a supernumerary tooth extracted at age 4. The dental clinical exam revealed giroversion of permanent maxillary right central incisor. Cone-beam computed tomography (CBTC) revealed a presence of a mesiodens located at the buccal surface mesially to the permanent maxillary left central incisor and also indicated that the mesiodens was located close to the f loor of the nasal cavity. The surgery was performed with a conservative intervention and osteotomy by preserving the adjacent structure. The one-year following-up postoperative x-ray indicated new bone deposition and a more favorable eruption position of the right permanent maxillary lateral incisor. Conclusion: It can be concluded that an early diagnosis by CBTC allowed an adequate treatment planning, which avoid the formation of cysts and a prolonged retention of permanent tooth.
