          Abstract

          Background

          Peripheral odontoma arising in the extraosseous soft tissues is rare and if not removed early, may enlarge over time and eventually erupt in the oral cavity.

          Case presentation

          A 15-year-old girl presented with “denticles on the gingiva”. During the intraoral examination, seven small tooth-like structures were found. These were exposed in the anterior left gingiva between the permanent maxillary lateral incisor and canine teeth, and the left first premolar was absent. Radiographic examination revealed irregular tooth-like structures without evidence of bone involvement.

          Conclusion

          The lesion was surgically removed, and the specimens were analyzed histopathologically. The diagnosis of compound odontoma was established.

          Clinical significance

          This is the twelfth reported case of peripheral odontoma in the gingiva and the first one that erupted in the oral cavity.

          Large erupting complex odontoma: a case report.

          Odontomas are the most common odontogenic tumours. They are usually asymptomatic and are often discovered during routine radiography. We report a case of a large erupting complex odontoma that caused pain, infection and facial asymmetry. This case is significant as there are few reports of complex odontoma erupting in the oral cavity.

            Intraosseous odontoma erupted into the oral cavity: an unusual pathology.

            Odontoma arising in the extraosseous soft tissue is extremely uncommon. Two forms of odontoma are presently recognized: peripheral odontoma and erupted odontoma. We report an erupted odontoma arising in the posterior maxilla, and discuss the main differences between both forms of clinical presentation.

              Erupted compound odontome

              Odontomas are considered to be hamartomas rather than a true neoplasm. They consist chiefly of enamel and dentin, with variable amount of pulp and cementum when fully developed. They are generally asymptomatic and are included under the benign calcified odontogenic tumors. They are usually discovered on routine radiographic examination. Eruption of an odontoma in the oral cavity is rare. Peripheral compound odontomas arise extraosseously and have a tendency to exfoliate. In this article we are reporting a case of a 15-year-old girl with peripheral compound odontoma, with a single rudimentary tooth-like structure in the mandibular right second molar region, which is about to be exfoliated. Its eruption in the oral cavity and location in the mandibular posterior region is associated with aplasia of the mandibular right second molar, making it an interesting case for reporting.
