They are usually asymptomatic and are mostly discovered during the routine radiographic investigation. Histologically, they are hamartomas composed of different dental tissues that grows slowly are benign and behave in a nonaggressive manner. We hereby report a case of a 32‑year‑old female patient, who reported to our Department of Oral and Maxillofacial Surgery with a hard, nonpainful swelling in the lower right posterior region of the jaw. KEY WORDS: Benign tumors, complex/compound odontomas, mandibular neoplasms, odontomas, radiopaque mass INTRODUCTION unilocular, and they are separated from the normal bone by a well‑defined cortical line.[1] A complex odontoma “Paul Broca,” was the first person to use the term presents as an amorphous conglomeration of dental odontoma in 1867, who defined the term odontoma as a tissues consisting of enamel, dentin, pulp, cementum, tumor formed by the overgrowth of transitory or complete and enamel organ.[1] The treatment plan of choice dental tissues. is surgical removal of the lesion in toto, followed by histopathological study for final diagnosis. We hereby Odontomas are slow growing benign neoplasms present a case of a rare complex odontoma covering on representing about 22% of the odontogenic tumors found an impacted mandibular third molar in a 32‑year‑old in the jaws.[1] They develop from the epithelial as well as female patient. mesenchymal components of the tooth bud producing enamel and dentin.[1] They can occur anywhere in both the mandible or maxilla without any predilection for age CASE REPORT or sex, although they are usually found in conjunction A 32‑year‑old female patient reported to Department of with primary teeth.[2] Oral and Maxillofacial Surgery with a chief complaint of pain and mild swelling in the lower right posterior region Radiographically, odontomas are classified as complex of the jaw since 2–3 months [Figure 1]. The patient had and compound odontomas.

Despite their benign nature, however, they may cause relative pain, infection, inflammation of the associated region, and pericoronitis of the overlying mucosa with a different Figure 9: Six months postoperative orthopentomogram clinical appearance.
