Odontogenic cysts and tumors are the most frequent osseous destructive lesions of the jaws; however, there is little information regarding the relative frequency of these lesions among the Iranian population.
The purpose of this study was to determine the distribution of clinically and histologically- diagnosed odontogenic cysts and tumors during a period of 13 years in Hamadan, and also its correlation with age, gender, and the site of the lesion.
A descriptive cross-sectional study was performed on 413 oral and maxillofacial specimens during 1996 to 2008.The age and the gender of patients, as well as the site of lesion were recorded. The data were analyzed using SPSS software.
Totally, 70 specimens were recorded as odontogenic cysts and 11 specimens were diagnosed as odontogenic tumors. The most frequent odontogenic cysts were dentigerous cysts (27.2%), followed by radicular cysts (18.6%) and odontogenic keratocysts (18.6%). In addition, cysts were more frequent in male than female individuals. Ameloblastoma was the most frequent odontogenic tumor (64%).
Odontogenic cysts were in correlation with age, gender and location. These results showed that dentigerous cyst and odontogenic keratocyst were more frequent than other studies. More investigations should be performed to determine the frequency of odontogenic tumors in Iran.
牙源性囊肿和肿瘤是颌骨中最常见的骨质破坏性病损；然而，关于这些病损在伊朗人群中的相对发病率的信息却很少。
本研究的目的是确定在哈马丹13年期间临床和组织学诊断的牙源性囊肿和肿瘤的分布情况，以及其与年龄、性别和病损部位的相关性。
对1996年至2008年期间的413例口腔颌面标本进行了描述性横断面研究。记录了患者的年龄、性别以及病损部位。使用SPSS软件对数据进行分析。
总共记录了70例牙源性囊肿标本，11例被诊断为牙源性肿瘤。最常见的牙源性囊肿是含牙囊肿（27.2%），其次是根端囊肿（18.6%）和牙源性角化囊肿（18.6%）。此外，囊肿在男性中比女性中更常见。成釉细胞瘤是最常见的牙源性肿瘤（64%）。
牙源性囊肿与年龄、性别和部位相关。这些结果表明含牙囊肿和牙源性角化囊肿比其他研究中更常见。应进行更多调查以确定伊朗牙源性肿瘤的发病率。
