Compound Odontoma in a 12-Year-Old Boy With Impacted Premolar: A Case Report.

Odontomas are the most frequent odontogenic tumours and may obstruct the eruption of permanent teeth. A 12-year-old boy was referred for a painless mandibular swelling and absence of tooth 45 on panoramic radiography. Clinical examination showed persistence of 85, cone beam computed tomography (CBCT) revealed a well-circumscribed radiopaque cluster surrounded by a radiolucent rim between 46 and 44, and tooth 45 was displaced lingually. Under local anaesthesia, conservative enucleation was undertaken. Histopathology confirmed a compound odontoma composed of multiple tooth-like structures. Three-month panoramic follow-up showed early bone fill, and at six months, periapical radiography confirmed continued healing. The patient was referred for orthodontic traction/guidance of 45.
