【摘要】：目的:探讨1例双侧下颌第二磨牙阻生伴牙旁囊肿的病因及治疗,为其诊治提供参考。方法:患者囊肿累及左下颌第一磨牙,术前行根管治疗,局麻下拔除左下颌第二磨牙,刮匙刮除病变区残余牙囊、肉芽组织及囊肿壁,球钻打磨创腔及尖锐骨创缘,并磨除左下颌第一磨牙远中部分根尖,术中取组织行组织病理学检查。结果:X线片可见双侧下颌第二磨牙近中阻生,左下颌第二磨牙冠周有一边界清楚类圆形密度减低区,邻牙牙根吸收。术后病理回报示牙旁囊肿。结论:牙齿阻生伴牙旁囊肿可发生于除第三磨牙以外的其余牙位,其诊断需结合临床表现、病理和影像学检查,多学科会诊有利于其诊断和治疗。
[Abstract]:Objective: to investigate the etiology and treatment of bilateral mandibular second molar impaction associated with parodontal cyst, and to provide reference for its diagnosis and treatment. Methods: the first molar of left mandible was involved in the cyst, root canal treatment was performed before operation, and the second molar of left mandible was extracted under local anesthesia. The residual bursa, granulation tissue and cyst wall in the lesion area were removed by curettage, and the wound cavity and sharp bone were ground with a ball drill, and the distal tip of the left first molar was removed. Results the bilateral mandibular second molars had proximal and middle impingement and there was a clear circular reduced density region around the crown of the left mandibular second molar. The pathological results of the adjacent tooth root resorption show the parodontoid cyst. Conclusion: tooth impaction with parodontoid cyst may occur in the other teeth except the third molar, and its diagnosis should be combined with clinical manifestation, pathology and imaging examination. Multi-disciplinary consultation is beneficial to its diagnosis and treatment.
