This study is based on an analysis of oral biopsy specimens that were diagnosed histopathologically in the Department of Oral Pathology, School of Dentistry, HIGASHI-NIPPON-GAKUEN UNIVERSITY from 1979-1989. 1. The total number of specimens during the ten years were 503 (dental hospital: 363, other personal dental clinics: 140), it corresponding to 440 cases (patients). 2. There were 224 men, 210 women, and 6 unknown. 3. The most common cases were radicular cysts 11.1% (49 cases), the second dental granuloma 9.5% (42 cases), followed by fibroma (fibrous polyp) 7.7% (34 cases). 4. The largest group of all specimens were cysts (35.7%), the second inflammatory lesions (28.0%), followed by tumors (26.6%). 5. About 80% of oral tumors were benign and about 20% were malignant. Of 24 cases with malignant tumors, the majority were squamous cell carcinoma (20 cases, 87%), followed by malignant melanoma (2 cases, 8.7%), verrucous carcinoma (1 case, 4.3%), and clear cell carcinoma (1 case, 4.3%). 6. About 13% of all oral tumors were odontogenic tumors, and the most common were ameloblastoma (8 cases, 53.3%), followed by odontoma (5 cases, 33.3%), and cementifying fibroma (2 cases, 13.3%). 7. The most common cases of specimens from other dental clinics were radicular cysts (23 cases, 16.4%), the second fibroma (fibrous polyp) (17 cases, 12.1%), and followed by dental granuloma (15 cases, 10.1%).
本研究基于对1979年至1989年在日本东北学园大学牙科学院口腔病理科进行组织病理学诊断的口腔活检标本的分析。1. 十年间标本总数为503例（牙科医院：363例，其他私人牙科诊所：140例），对应440例患者。2. 男性224例，女性210例，6例性别不明。3. 最常见的病例是牙根囊肿，占11.1%（49例），其次是牙肉芽肿，占9.5%（42例），然后是纤维瘤（纤维性息肉），占7.7%（34例）。4. 所有标本中最大的一组是囊肿（35.7%），其次是炎症性病变（28.0%），然后是肿瘤（26.6%）。5. 约80%的口腔肿瘤为良性，约20%为恶性。在24例恶性肿瘤病例中，大多数是鳞状细胞癌（20例，87%），其次是恶性黑色素瘤（2例，8.7%），疣状癌（1例，4.3%），以及透明细胞癌（1例，4.3%）。6. 所有口腔肿瘤中约13%为牙源性肿瘤，最常见的是成釉细胞瘤（8例，53.3%），其次是牙瘤（5例，33.3%），以及牙骨质化纤维瘤（2例，13.3%）。7. 其他牙科诊所标本中最常见的病例是牙根囊肿（23例，16.4%），其次是纤维瘤（纤维性息肉）（17例，12.1%），然后是牙肉芽肿（15例，10.1%）。
