Introduction: Ameloblastic fibro-odontoma (AFO) is a benign complex odontogenic tumor in the mandible in children and adolescents. Observation: A 9-year-old boy was referred to the dental department for the delayed eruption of tooth 26. He was asymptomatic, and on clinical examination, we found that tooth 26 was absent with tumefaction instead of the tooth. Cone beam computed tomography revealed an opaque mass in the root of 26. The management was surgical, and anatomopathological examination facilitated the diagnosis of AFO. Commentary: The upper maxillary localization of AFO is rare and is not often a practitioner's first thought. Surgical excision of the tumor is essential based on the histological diagnosis. The patient must be followed up after 3 months and regularly until the eruption of the affected tooth. Conclusion: AFO is one of the differential diagnoses to be considered when a young patient presents with firm swelling with delayed eruption of the opposing tooth, especially since it has good prognosis and is easy to manage.

-Introduction: Neurofibromatosis type I (NF1) is a genetic disease that may involve oral manifestations such as supernumerary teeth. Case report: A 17-year-old male patient with NF1 was referred by an orthodontist for avulsion of wisdom teeth and six supernumerary teeth. Ten teeth were removed under general anesthesia in December 2015. Discussion: Management of supernumerary teeth is very controversial and patient care of NF1 is complex. Conclusion: Even though the presence of supernumerary teeth in cases of NF1 is not well-known, patient care is extremely important and requires a team of specialists.Résumé -Les dents surnuméraires dans la neurofibromatose de type I : cas clinique et revue de la littéra-ture. Introduction : La neurofibromatose de type I est une maladie génétique qui peut induire des manifestations orales comme la présence de dents surnuméraires. Observation clinique : Un homme de 17 ans présentant une NF1 a été adressé par son orthodontiste pour l'avulsion de ses dents de sagesse et 6 dents surnuméraires. Les 10 dents ont été extraites sous anesthésie générale en décembre 2015. Discussion : La prise en charge des dents surnuméraires est très controversée et la prise en charge des patients atteints de NF1 est complexe. Conclusion : Même si la présence de dents surnuméraires chez les patients atteints de NF1 est mal connue, la prise en charge de ces patients est très importante et une équipe pluridisciplinaire est nécessaire.
