A 14-year retrospective study was performed on 47 odontomas from the files of the 1st Department of Oral and Maxillofacial Surgery at Nihon University School of Dentistry. Fifty-seven percent of the patients were male and 42.6% were female. The age distribution was 8 to 48 years with a mean age of 22 +/- 9.0 years. There were no particular symptoms associated with the odontomas, and 63.8% of our patients had no symptoms. However, 12 patients complained of swelling and 9 of pain. The tumor was found in the maxilla in 42.6% and in the mandible in 57.4%. According to the WHO histological type classification, 53.2% of the tumors were classified as compound odontoma and 46.8% as complex odontoma. The size of the tumor ranged from 5 mm to 42 mm in diameter. The average complex odontoma was much bigger than the average compound odontoma. Ghost cells were found 11 cases in our series. In addition, odontogenic epithelium was found in 16 cases. Twenty seven patients had impacted teeth in association with odontoma and 24 of the 27 teeth were removed at the time of surgical enucleation of the tumor, while 3 cases were treated by orthodontically assisted eruption. There was no recurrence in any of the studied cases.
对日本大学牙科学院口腔颌面外科第一部存档的47例牙瘤进行了一项为期14年的回顾性研究。患者中57%为男性，42.6%为女性。年龄分布为8至48岁，平均年龄为22±9.0岁。牙瘤无特定症状，63.8%的患者无症状。然而，12例患者主诉肿胀，9例主诉疼痛。肿瘤位于上颌骨的占42.6%，位于下颌骨的占57.4%。根据世界卫生组织组织学类型分类，53.2%的肿瘤被归类为复合性牙瘤，46.8%为复杂性牙瘤。肿瘤大小直径范围为5毫米至42毫米。平均而言，复杂性牙瘤比复合性牙瘤大得多。本系列中有11例发现了牙釉质细胞。此外，16例发现了牙源性上皮。27例患者的牙瘤伴有阻生牙，其中24颗牙在肿瘤手术摘除时被拔除，3例采用正畸助萌治疗。所有研究病例均无复发。
