髓室底或根管侧壁穿孔是指由于医源性原因、龋坏、病理性吸收等造成髓室或根管穿通至牙周组织。该症常引起穿孔处组织反复肿胀、顽固性咬合疼痛及骨组织丧失,导致治疗失败,进而需拔除患牙。2007年12月-2008年12月,我们采用无机三氧化聚合物(MTA)修补髓室底与根管侧壁穿孔17例,疗效满意。现分析报告如下。 The perforation of the pulp chamber or root canal wall refers to the penetration of the pulp chamber or root canal into the periodontal tissue due to iatrogenic causes, carious lesions, pathological absorption, and the like. The disease often causes repeated tissue perforation at the swelling, intractable bite pain and loss of bone tissue, resulting in treatment failure, and then need to remove the affected teeth. December 2007 - December 2008, we use inorganic trioxometalate (MTA) to repair 17 cases of perforation of the medullary canal and canal wall, with satisfactory results. The analysis report is as follows.
