A study on odontogenic cysts and tumors.
The aim of this study is to determine the frequency of odontogenic cysts and tumors and their distribution according to age, gender, site and histopathologic types of those reported over a period of 1998-2012 in a Tertiary Health Care Center at South Kerala.
The archives of Department of Oral Pathology and Microbiology, were retrospectively analyzed.
Archival records were reviewed and all the cases of odontogenic cysts and tumors were retrieved from 1998 to 2012.
Descriptive statistical analysis was performed using the computer software, Statistical Package for Social Sciences (SPSS) IBM SPSS Software version 16.
Of 7117 oral biopsies, 4.29% were odontogenic tumors. Ameloblastoma was the most common odontogenic tumor comprising 50.2% of cases, followed by keratocystic odontogenic tumor (24.3%). These tumors showed a male predilection (1.19: 1). Odontogenic tumors occurred in a mean age of 33.7 ± 16.8 years. Mandible was the most common jaw affected (76.07%). Odontogenic cysts constituted 12.25% of all oral biopsies. Radicular cyst comprised 75.11% of odontogenic cysts followed by dentigerous cyst (17.2%).
This study showed similar as well as contradictory results compared to other studies, probably due to geographical and ethnic variations which is yet to be corroborated.
一项关于牙源性囊肿和肿瘤的研究。
本研究的目的是确定1998年至2012年期间在南喀拉拉邦一家三级医疗保健中心报告的牙源性囊肿和肿瘤的发生率及其按年龄、性别、部位和组织病理学类型的分布情况。
对口腔病理学和微生物学系的档案进行回顾性分析。
查阅档案记录，检索1998年至2012年期间所有牙源性囊肿和肿瘤病例。
使用计算机软件社会科学统计软件包（SPSS）IBM SPSS软件版本16进行描述性统计分析。
在7117例口腔活检中，4.29%为牙源性肿瘤。成釉细胞瘤是最常见的牙源性肿瘤，占病例的50.2%，其次是角化囊性牙源性肿瘤（24.3%）。这些肿瘤显示男性居多（1.19:1）。牙源性肿瘤的平均发病年龄为33.7±16.8岁。下颌骨是最常受累的颌骨（76.07%）。牙源性囊肿占所有口腔活检的12.25%。根尖囊肿占牙源性囊肿的75.11%，其次是含牙囊肿（17.2%）。
与其他研究相比，本研究显示了相似以及矛盾的结果，可能是由于地理和种族差异，这还有待证实。
