犬含牙囊肿病例报告

Case Report of Canine Dentigerous Cyst

本院接诊了1例乳齿未脱、右下颌恒犬齿缺失的患犬病例,将患犬麻醉后采用口腔探查和X线检查的方法进行诊断,初步诊断该患犬为含牙囊肿,即由未萌出的右下颌恒犬齿发育过程中相关的残留上皮所形成。手术拔除未萌发犬齿,使用刮匙将囊壁完整去除,用金刚砂车针打磨囊壁齿槽骨并使用生理盐水冲洗囊腔,结节缝合齿龈黏膜,术后恢复良好。患犬于术后3个月复查,镇静后拍摄口腔X线片,可见有新骨生成,无囊肿复发表现。表明治疗含牙囊肿时,拔除未萌发的牙齿并将囊壁清理干净,可获得良好的预后,但需要结合口腔X线和组织病理学检查结果进行诊断,后续需要进行影像学监测。

This report presents a case of a canine with retained deciduous teeth and missing permanent mandibular teeth on the right side.The dog was diagnosed with a dentigerous cyst using oral exploration and X-ray examination after anesthesia.The cyst was formed by residual epithelium associated with the developmental process of the unerupted permanent mandibular teeth.Surgical treatment involved extraction of the unerupted teeth,complete removal of the cystic wall using curettes,grinding of the alveolar bone with a diamond bur,irrigation of the cystic cavity with normal saline,and closure of the gingival mucosa.The postoperative recovery was satisfactory.A follow-up examination at 3 months postoperatively revealed new bone formation on dental X-rays,with no signs of cyst recurrence.This case highlights that a favorable prognosis can be achieved by removing unerupted teeth and thoroughly cleaning the cystic wall during the treatment of dentigerous cysts.However,diagnosis should be confirmed with oral X-rays and histopathological examination,and follow-up imaging monitoring is necessary.
