Delayed Diagnosis and Multidisciplinary Management of a Compound Odontoma With Associated Dental Anomalies: A Rare Case Report.

Hyperdontia is a developmental anomaly that can disrupt normal tooth eruption and occlusal harmony. Compound odontomas, although benign and often asymptomatic, may cause delayed eruption and other complications requiring surgical management. This case report details the treatment of a 22-year-old female presenting with failure of eruption of the mandibular left permanent canine. Clinical and radiographic evaluation revealed a retained deciduous canine, a compound odontoma, and a horizontally impacted supernumerary tooth. Surgical intervention under local anesthesia involved extraction of the retained deciduous and supernumerary teeth, complete removal of the odontoma, and surgical exposure of the impacted canine with placement of an orthodontic traction chain to facilitate eruption. Postoperative recovery was uneventful, with satisfactory soft tissue healing and partial eruption of the permanent canine observed at the 3-month follow-up. This case emphasizes the importance of early diagnosis and timely management of odontogenic anomalies to prevent functional and esthetic complications. Coordinated surgical and orthodontic intervention can significantly improve prognosis and treatment outcomes.
