Summary:Hyperplastic dental follicles cause fibrous tissue hyperplasia around the crown of an impacted tooth. Their radiological findings are similar to those of dentigerous cysts, and differential diagnosis is difficult. This case involved an 11-year-old female with a history of a tumor affecting a mandibular canine. The histopathological diagnosis of the tumor was a compound odontoma. The impacted canine was followed. After 4 years of follow-up, panoramic radiography showed an increase in radiolucency surrounding the crown. Biopsy and fenestration were performed for a suspected dentigerous cyst. The histopathological diagnosis was a hyperplastic dental follicle, and the patient underwent extraction of the canine tooth and cyst removal under local anesthesia. The histopathological diagnosis of the excised specimen was a hyperplastic dental follicle. We experienced a case in which a hyperplastic dental follicle arose during follow-up after odontoma removal, and reported its clinical course and radiographic findings.
