title: Gingival peripheral odontoma in an adult: case report.
abstract: BACKGROUND
  Odontoma arising in the extraosseous soft tissue is extremely uncommon. We describe our experience of gingival peripheral odontoma in which the initial presentation was a small asymptomatic nodule.
  
  
  METHODS
  Case study.
  
  
  RESULTS
  A 44-year-old man reported with a firm gingival mass of the anterior maxilla which had been gradually enlarging over 5 years. Radiographic examination showed a dense radiopaque mass occupying most of the tumor and no evidence of underlying intraosseous lesion. The pathology was reported as odontoma.
  
  
  CONCLUSIONS
  This is the fourth reported case of peripheral odontoma in the gingiva.
