An odontoma refers to any tumor of odontogenic origin. Three distinct types of odontomas have been distinguished in the dental literature: complex, compound, and ameloblastic fibro-odontoma. Odontomas are usually associated with overly retained primary and unerupted permanent teeth. The exact etiology of odontomas is unknown, but local trauma, infection, inheritance, and genetic mutation have been postulated as possible causes of odontomas. Studies have found that males are more likely than females to have odontomas, with most frequent occurrence in the second decade of life. One hundred four biopsy reports with a diagnosis of odontoma were analyzed for age, race, gender, location, pre-operative diagnosis, and postoperative laboratory findings. Most odontomas occurred in the 11-20 age group, with Caucasians predominating. The majority were located in the maxilla, and 85 percent were correctly diagnosed clinically by the attending dentist prior to confirmation by histologic pathology reports of the biopsy specimens. The vast majority were compound odontomas (64.4%) with complex odontomas comprising 31.0% of the total lesions. No ameloblastic fibro-odontomas were diagnosed.
牙瘤是指任何起源于牙源性的肿瘤。在牙科文献中已区分出三种不同类型的牙瘤：复合性牙瘤、组合性牙瘤和成釉细胞纤维牙瘤。牙瘤通常与过度滞留的乳牙和未萌出的恒牙有关。牙瘤的确切病因尚不清楚，但局部创伤、感染、遗传和基因突变被认为是牙瘤可能的病因。研究发现，男性比女性更易患牙瘤，最常见于生命的第二个十年。对104份诊断为牙瘤的活检报告进行了年龄、种族、性别、位置、术前诊断和术后实验室检查结果的分析。大多数牙瘤发生在11至20岁年龄组，以白种人为主。大多数位于上颌骨，85%在活检标本的组织病理学报告确认之前，经主治牙医临床正确诊断。绝大多数是组合性牙瘤（64.4%），复合性牙瘤占全部病变的31.0%。未诊断出成釉细胞纤维牙瘤。
