Central odontogenic fibroma(COF) is a very rare benign tumor that accounts for 0.1-1.5% of all odontogenic tumors. Most COF develop in the molar-premolar region in the mandible and anterior to the first molar in the maxilla. Radiographically, the lesions appear as a unilocular or multilocular radiolucent image. Some maxillary lesions have cleft like depression in the palatal mucosa are found. This report presents a COF with external root resorption and palatal soft tissue depression on CBCT images. A 27-year-old man referred for evaluation of unilocular radiolucent lesion with external root resorption in the right anterior maxillary region. On clinical examination, the right anterior maxillary teeth responded positive to the cold stimulus and its response to the vitality test remained within the normal range. On radiographic examination, osteolytic lesion with external root resorption and palatal mucosa depression as a radiolucent shadow. After excisional biopsy, the lesion was diagnosed as COF in histopathologic examination. There was no recurrence at a follow-up 10 months.
