Abstract: Segmental odontomaxillary dysplasia (SOD) is a rare, non-hereditary, and developmental condition affecting the bone that was first recognized by Miles and colleagues as a type of hemimaxillofacial dysplasia (HFD). It was later separated by Danforth et al. The difference between them was the ipsilateral facial hypertrichosis which occurs with HFD. SOD occurs unilaterally in the maxilla mostly extending from the canine to the tuberosity on the same side. According to the literature, there is no clear underlining cause for this condition. Danforth and associates demonstrate the oral manifestation and the dental anomaly associated with SOD. To illustrate this rare condition we are presenting a case of SOD with five years follow up.

Case Report:
A 20-year-old female presented for extraction and sinus lift. Her medical history was significant for attention-deficit/hyperactivity disorder (ADHD), and asthma. On clinical examination, there was no facial asymmetry. Intra-orally, hard gingival swelling and missing teeth in the left maxilla were noted. Radiographs depicted abnormal bony trabeculation in the same quadrant with vertically oriented trabeculation and enlargement in the buccolingual dimension. There was no significant change radiographically in the size or the shape of the entity for five years.

Conclusion:
Since this entity has a wide range of clinical manifestation patients may seek care from multiple different dental and medical providers before a correct diagnosis is made. Familiarity with the clinical and radiographic findings of SOD greatly increases the likelihood of diagnosis and appropriate treatment
