Abstract
Few reports of the ameloblastic fibroma at the deciduous dentition stage have been made due to its rare occurrence. This case report describes an ameloblastic fibroma that occurred in the mandible of a 3-year-old boy.A health examination for the 3-year-old boy revealed impaction of deciduous molar. A panoramic radiograph, taken in the neighboring dental office, showed impaction of the mandibular right second deciduous molar with translucent area around its coronal part. The patient was therefore referred to the Pediatric Dentistry Clinic, School of Dentistry, Aichi-Gakuin University for more detailed examination. CT findings suggested an odontogenic tumor. The patient underwent tumor resection and fenestration, and the tumor was histopathologically diagnosed as ameloblastic fibroma. In this case, the health examination discovered the impacted deciduous molar, which would rarely be a chief complaint by the parents, illustrating the importance of the health examination.There has been no recurrence for 1 year postoperatively. Periodic radiography and long-term follow-up will be necessary to verify the presence or absence of recurrence, eruption of the mandibular right second deciduous molar, tooth germ formation of the successor permanent teeth, and the growth of the mandible.
