A case of central odontogenic fibroma with the impacted deciduous second molar in a 3-year-old boy is presented. Panoramic radiograph demonstrated a monolocular radiolucent lesion over the crown of the deciduous second molar. Under clinical diagnosis of a dentigerous cyst or benign tumor, the lesion was extirpated, and the crown was exposed to the oral cavity by marsupialization. The removed specimen was histologically diagnosed as odontogenic fibroma. The impacted deciduous second molar erupted completely in normal position 1 year after marsupialization. A tooth germ of the permanent second premolar was observed on the panoramic radiograph 3 years and 5 months after surgery, and there was no evidence of the tumor recurrence after 4 years.
