Abstract

BackgroundPeripheral 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 presentationA 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.ConclusionThe lesion was surgically removed, and the specimens were analyzed histopathologically. The diagnosis of compound odontoma was established.Clinical significanceThis is the twelfth reported case of peripheral odontoma in the gingiva and the first one that erupted in the oral cavity.

Highlights

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
Clinical significance: This is the twelfth reported case of peripheral odontoma in the gingiva and the first one that erupted in the oral cavity
We report a case of a 15-year-old girl with a peripheral compound odontoma characterized by multiple rudimentary teeth which erupted spontaneously in the anterior maxillary region

Summary

Conclusion

Due to the rare occurrence of peripheral odontomas, the present case is the first report of an erupted peripheral odontoma. It is important to note that the increased tooth mobility caused by these lesions may result in the spontaneous exfoliation of these denticles, which may lead to the patient swallowing them. Clinical significance This is the twelfth reported case of peripheral odontoma in the gingiva and the first one that erupted in the oral cavity. NGG accompanied the clinical case and drafted the article. MRGS accompanied the clinical case and drafted the article.
