Abstract:

The cystic lesions of the jaws are mostly asymptomatic, can continue growing to a considerable size, usually cause bone expansion, facial deformity, impacted tooth/teeth, displacement and loosening of the originating tooth or adjacent teeth, and occlusion disorder. The causative tooth of an apical periodontal cyst is treated with root canal therapy either shortly before operation or extraction during enucleation. When the standing tooth/teeth of the pulp vitality is associated with odontogenic developmental cysts or cystic tumors, especially tooth roots are protruded into the cyst cavity, many questions are be answered: how to treat involved teeth, be preserved or extracted in connection with enucleation, when is root canal treatment performed, whether apicectomy is carried out. Impacted tooth enclosed in the cavity of developmental cysts may be treated by various approaches, such as marsupialization,enucleation in combination with extraction or coronectomy according to patient's age, root development, the angle and the depth of the impacted toothas well as location and size of the lesion in the jaw. We reported our experience regarding the management of tooth/teeth associated with the cystic lesions of the jaws and reviewed the recent literatures

摘要:

颌骨囊肿及部分囊性肿瘤持续生长,可造成面部畸形,牙萌出障碍、松动移位,咬合关系紊乱等。牙髓活力丧失的根尖周囊肿的病源牙,常采用根管治疗术或囊肿刮除术中拔除。而牙源性发育性囊肿或囊性肿瘤累及的健康牙,尤其是牙根突入病变内时如何处理,保留或是术中拔除,何时根管治疗,是否行根尖切除等,尚无一致的意见。对于牙源性发育性囊肿内的阻生牙,根据患者年齡、牙的发育阶段、深度与角度,以及病变部位与大小等,有多种不同处理方式,如袋形术、刮除术中牙拔除或截冠术等。本文复习近年的文献,并结合作者的经验,介绍颌骨囊性病变受累牙处理的现代理念与方法。
