Ameloblastic fibro-odontoma (AFO) is a rare, benign epithelial mixed odontogenic tumor. It occurs as an intraosseous lesion, generally asymptomatic and more prevalent in children and adolescent. AFO is found on radiographic evaluation of patients with unerupted or impacted teeth in many cases. Histological examination reveals a fibrous soft tissue, islands of odontogenic epithelium and a disordered mixture of dental tissues. The treatment modality in most cases involves conservative surgery with enucleation. We present a case of 13-year-old boy with a missing right central incisor, mimicking-like odontoma on radiograph but proved to be AFO and treated with enucleation with preservation of impacted tooth. There was no recurrence after one year of follow-up. This report discusses the clinical, radiographical, histological features and surgical assessment to preserve the impacted tooth associated with AFO.
成釉细胞纤维牙瘤（AFO）是一种罕见的良性上皮性混合牙源性肿瘤。它表现为骨内病变，通常无症状，在儿童和青少年中更为常见。在许多病例中，AFO是在对未萌出或阻生牙患者进行影像学评估时发现的。组织学检查显示为纤维软组织、牙源性上皮岛和牙组织的无序混合。大多数情况下的治疗方式包括采用刮除术的保守手术。我们报告一例13岁男孩，其右侧中切牙缺失，X线片上类似牙瘤，但经证实为AFO，并采用刮除术治疗，同时保留了阻生牙。随访一年后无复发。本报告讨论了与AFO相关的临床、影像学、组织学特征以及保留阻生牙的手术评估。
