To analyze the relative frequency of different types of odontogenic tumors based on the WHO 2005 histopathological classification of odontogenic tumours and to compare the data with published literature.
Data collected from seven different hospitals in the same region of the city (south Chennai) were systematically searched for all cases of odontogenic tumors operated on between the years 2005-2010. The histopathology slides of the tumours were reanalyzed for cross verification. The data were also checked for duplication and for recurrence cases. Age, gender and site prevalence were also studied.
Of the 107 cases collected, with full records, 60 (56%) were odontomas. The second most common was ameloblastoma (14%), followed by Keratocystic odontogenic tumour (13%). The rest of the tumours formed 17% of the total.
A comprehensive tumour database should be initiated so that cross referring of cases would be easier and the patients, surgeons and the pathologists would be able to safe guard the information about the tumour for future reference. Many private hospitals lack the facility to store and catalogue histopathological evidences for a prolonged period of time.
根据世界卫生组织2005年牙源性肿瘤组织病理学分类分析不同类型牙源性肿瘤的相对频率，并将数据与已发表文献进行比较。
系统检索从该市同一地区（金奈南部）七家不同医院收集的2005年至2010年间所有牙源性肿瘤手术病例的数据。对肿瘤的组织病理学切片进行重新分析以进行交叉验证。还检查了数据的重复性和复发病例。同时研究了年龄、性别和部位患病率。
在收集的107例有完整记录的病例中，60例（56%）为牙瘤。第二常见的是成釉细胞瘤（14%），其次是牙源性角化囊性瘤（13%）。其余肿瘤占总数的17%。
应建立一个全面的肿瘤数据库，以便更方便地交叉参考病例，患者、外科医生和病理学家能够保存有关肿瘤的信息以供将来参考。许多私立医院缺乏长时间存储和编目组织病理学证据的设施。
