he intraosseous compound odontoma is a hamartoma which results in conglomerates of calcified masses resembling multiple tooth-like structures. Diagnosing this hamartomatous malformation is challenging since it occurs beneath the gingival margin. Cone-beam computed tomography helps to make a radiographic diagnose and visualize such compound odontoma. Cone-beam computed tomography helps identify and plan treatment for such concrescence of impacted supplementary teeth to prevent postoperative surgical complications such as maxillary tuberosity or oroantral fistula fracture. Purpose. To present and detect a case of compound odontoma by CBCT (cone-beam computed tomography). Materials and Methods. The article presents an incidental radiographic description of compound odontomas in a 21-year-old female diagnosed using cone-beam computed tomography. CBCT sxial and sagittal section is presented, revealing the compound odontome's exact position within the mandibular alveolar bone. The clinical significance of CBCT in radiographic diagnosis of compound odontoma was described. Results. CBCT is essential and helps identify the exact three-dimensional location of rare pathologies such as compound odontome. Discussion. CBCT helps precisely locate the position of compound odontoma, which can remain silent and asymptomatic within the jaw bone. The use of CBCT preoperatively helps to locate complex supernumerary teeth and to plan surgical treatment. Conclusion. Cone-beam computed tomography is essential for the identification and exact three-dimensional location of impacted compound odontoma. Dentists must have a sound knowledge of rare developmental tooth anomalies such as compound odontoma, which are incidentally detected on radiographic evaluation. © 2025 I.M.
