A Rare Compound Odontoma in Mandibular Midline Region: Case Report and Literature Review

Background: Odontomas are the most common odontogenic tumors of the oral cavity. Although compound odontomas are common in the pediatric population, they are rare in the mandibular midline region during the primary dentition stage. Case Description: This article provides a rare case-report and literature review of a compound odontoma in the mandibular midline region during the primary dentition stage. A routine occlusal radiograph in an asymptomatic six-year-old patient demonstrated mixed, radiolucent-radiodense lesion apical to #N-#P (mandibular primary incisors) with intact lamina dura. Minor expansion and thinning of labial and lingual cortices were noted on cone beam computed tomographic (CBCT) images. This report discusses surgical management, histopathologic diagnosis, and 36-month clinical-radiographic follow-up of our case. Practical Implications: Compound odontomas are highly rare during the primary dentition stage in the mandibular midline (0.3%). Routine radiographs are vital for a timely diagnosis and treatment of these pathologies to prevent future orthodontic complications.
