Ameloblastic fibrodentinoma (AFD) is a rare benign mixed odontogenic tumor that occurs predominantly in children and young adults. AFD is usually associated with delayed eruption of the tooth and shows painless swelling. We present a case of AFD affecting an 8-year-old Japanese girl with a complaint of delayed eruption of her left mandibular second premolar tooth. Intraoral examination did not reveal any sign of pain or swelling in the left mandible. Panoramic radiography revealed a radiolucent and well-circumscribed lesion, which contained radiopaque material at the premolar lesion of the left mandible. The second deciduous molar tooth was unerupted and the second premolar tooth was congenitally lacking. Our provisional diagnoses were odontogenic tumor. The biopsy confirmed AFD. The treatment included total excision of the tumor and the second premolar tooth. No recurrence has been noted during the 2 years of follow-up.
成釉细胞纤维牙本质瘤（AFD）是一种罕见的良性混合性牙源性肿瘤，主要发生于儿童和青年。AFD通常与牙齿萌出延迟有关，并表现为无痛性肿胀。我们报告一例AFD病例，患者为一名8岁日本女孩，主诉左下颌第二前磨牙萌出延迟。口腔检查未发现左下颌有任何疼痛或肿胀迹象。全景X线片显示左下颌前磨牙区有一透射性且边界清晰的病变，病变内含有不透射线物质。第二乳磨牙未萌出，第二前磨牙先天性缺失。我们初步诊断为牙源性肿瘤。活检证实为AFD。治疗包括肿瘤及第二前磨牙的完整切除。随访2年未见复发。
