BACKGROUND
The aim of this study was to determinate the relative frequency of odontogenic tumors (OTs) in a Brazilian population and to compare this data with previous reports.
METHODS
We reviewed the achieves of 19 123 specimens from oral pathology laboratory of Universidade Federal de Minas Gerais, from 1954 to 2004. Using the criteria of histologic typification published by the World Health Organization in 1992, we classified the OTs.
RESULTS
A total of 340 OTs were found. The frequency of OTs comprises 1.78% of all pathologic specimens in our laboratory. The most frequent tumor was ameloblastoma (45.2%), followed by odontomas (24.91%), and myxomas (9.1%).
CONCLUSIONS
Odontogenic tumors are uncommon lesions in this Brazilian population and malignant OTs are very rare. The relative frequency of various types of OTs, age, and gender distribution are similar to those reported in African, Asian but not to Chilean and North American series.
背景
本研究的目的是确定巴西人群中牙源性肿瘤（OTs）的相对发生率，并将该数据与先前的报告进行比较。
方法
我们回顾了1954年至2004年米纳斯吉拉斯联邦大学口腔病理实验室的19123份标本记录。根据世界卫生组织1992年公布的组织学分类标准，我们对牙源性肿瘤进行了分类。
结果
共发现340例牙源性肿瘤。牙源性肿瘤的发生率占我们实验室所有病理标本的1.78%。最常见的肿瘤是成釉细胞瘤（45.2%），其次是牙瘤（24.91%）和黏液瘤（9.1%）。
结论
牙源性肿瘤在该巴西人群中是罕见病变，恶性牙源性肿瘤非常罕见。各种类型牙源性肿瘤的相对发生率、年龄和性别分布与非洲、亚洲报告的情况相似，但与智利和北美系列不同。
