Tumors of the odontogenic origin (OTs) are rare tumors accounting for 1% of all the jaw tumors in the oral cavity. The behavior of these tumors ranges from hamartomatous proliferation to malignant neoplasm.
The aim of this study was to determine the epidemiological data, clinical and histopathological picture with variants of the OTs diagnosed at our institute in the Vidarbha region.
A retrospective study was carried out with the permission from the institutional authorities. The archival records of the Department of Oral Pathology and Microbiology were reviewed.
A total of 93 cases of OTs were reviewed retrospectively from the archival records of the Department of Oral Pathology and Microbiology from January 2008 to December 2018. Statistical analysis was carried out and the determination of the age, gender, jaw, site, diagnosis, variants and year-wise distribution of odontogenic lesions was taken out using the SPSS software.
Ninety-three cases of OTs were identified. The most common OT identified was ameloblastoma ( = 37/39.7%) followed by keratocystic OT ( = 8/8.6%), adenomatoid OT ( = 7/7.5%) and odontome (O) ( = 6/6.4%). The tumors were diagnosed in a wide age range from 1 to 3 decennium of life. The mandibular posterior region was the most commonly affected anatomical site with the maxilla and mandible ratio of 1:6.
OTs were found to be rare in the sample studied. The findings of the study were in concordance to those of Asian and African series. Variations were shown from the series of American reports, and further investigations are needed for this disparity.
牙源性肿瘤（OTs）是罕见肿瘤，占口腔颌骨肿瘤的1%。这些肿瘤的行为从错构瘤性增殖到恶性肿瘤不等。
本研究的目的是确定在我们位于维达巴地区的研究所诊断出的牙源性肿瘤的流行病学数据、临床和组织病理学特征及其变异情况。
在获得机构当局许可后进行了一项回顾性研究。对口腔病理学和微生物学系的存档记录进行了审查。
从口腔病理学和微生物学系2008年1月至2018年12月的存档记录中回顾性分析了93例牙源性肿瘤病例。进行了统计分析，并使用SPSS软件确定了牙源性病变的年龄、性别、颌骨、部位、诊断、变异及逐年分布情况。
共鉴定出93例牙源性肿瘤。最常见的牙源性肿瘤是成釉细胞瘤（37例/39.7%），其次是角化囊性牙源性肿瘤（8例/8.6%）、腺样牙源性肿瘤（7例/7.5%）和牙瘤（6例/6.4%）。这些肿瘤在1至3个十年的广泛年龄范围内被诊断出来。下颌后部区域是最常受累的解剖部位，上颌与下颌的比例为1:6。
在所研究的样本中发现牙源性肿瘤较为罕见。本研究结果与亚洲和非洲系列研究结果一致。与美国报告系列存在差异，需要对此差异进行进一步研究。
