按世界卫生组织（ＷＨＯ）１９９２年新分类标准对８２１例牙源性肿瘤重新诊断归类，统计分析不同类型的构成比例、年龄、性别及部位分布。结果显示最常见的牙源性肿瘤是造釉细胞瘤（５３．８％），与北美地区报道牙瘤（５１．４～６７．０％）常见结果不一致。男性患者略多于女性（１．３：１），高发年龄为１０～３９岁（６９．ｏ％）。下颌骨多于上颌骨（３．１：１），且以下颌磨牙区和下颌角区最常见（４３．２％），其中造釉细胞瘤下颌骨与上颌骨之比为１２．７：１，远高于北美地区的报道（２．５：１）。 According to the World Health Organization (WHO) 1992 new taxonomic classification of 821 odontogenic tumors re-diagnosis, statistical analysis of different types of composition ratio, age, gender and site distribution. The results showed that the most common odontogenic tumor was ameloblastoma (53.8%), which was inconsistent with the common findings of odontoma (51.4-67.0%) in North America. Male patients slightly more than women (1.3: 1), high incidence of 10 to 39 years old (69.%). There were more mandibular than maxillary (3.1: 1) mandibular molars and mandibular angle (43.2%). The ratio of mandibular to maxilla was 12.7: 1 , Much higher than those reported in North America (2.5: 1).
