Treatment of ameloblastic fibro-odontoma on a 3-year-old child: case report

Ameloblastic fibro-odontoma (AFO) is a rare benign odontogenic tumor with characteristics of ameloblastic fibroma and enamel/dentin components. This study reports the case of a 3-year-old boy with swelling and delayed tooth eruption in the posterior mandibular region. Orthopantomography revealed a radiopaque mass in the left mandible with cortical bone infiltration. The diagnosis was confirmed through incisional biopsy. Treatment involved marginal resection and curettage, preserving the lingual cortical. Surgical planning was made using 3D biomodels. Osteosynthesis was performed using an L-shaped plate from the 1.5 system. At a four-year follow-up, the patient showed normal facial growth, satisfactory healing, and no signs of recurrence, highlighting conservative marginal resection as an effective approach to preserve mandibular contour, support facial growth, reduce recurrence risk and multiple surgical interventions, such as orthognathic surgeries.
