Abstract：
Segmental odontomaxillary dysplasia (SOD) is a rare and unusual nonhereditary developmental disorder that affects one side of the maxilla, impacting the hard tissue, soft tissue, and dentition in the affected area. It most frequently presents with enlargement of the gingival and osseous tissue of the affected side and hypodontia of the involved quadrant. Cutaneous irregularities of the impacted area are also common. We report a case of SOD arising in the right maxilla of a three-year-old female. Our report and review of the literature highlight the clinical, radiographic, and histopathologic characteristics of SOD, as well as the management of patients and the proposed etiologies of its pathogenesis.
