Periapical diseases are induced as a result of the direct or indirect involvement of oral bacteria. The etiologic factor being the degenerating pulp tissue. A periapical lesion is formed within an area of apical periodontitis which cannot form by itself and is inflammatory in origin. If the microbial etiology of periapical lesions and in the root canal is removed by nonsurgical root canal therapy the lesions regress. Mere surgical removal of the periapical lesions without proper root canal disinfection and obturation will not result in the healing of periapical tissues. Nonsurgical treatment with triple antibiotic paste offers a high success rate in the healing of large periapical lesions. The present clinical cases show the nonsurgical endodontic management of large periapical pathosis using triple antibiotic paste and mineral trioxide aggregate.
根尖周病是由口腔细菌直接或间接感染引起的。病因是牙髓组织退变。根尖周病变是在根尖周炎区域内形成的，根尖周炎自身无法形成，且起源于炎症。如果通过非手术根管治疗去除根尖周病变和根管内的微生物病因，病变就会消退。仅仅手术切除根尖周病变而不进行适当的根管消毒和充填，不会导致根尖周组织愈合。使用三联抗生素糊剂进行非手术治疗在大型根尖周病变的愈合方面成功率很高。目前的临床病例展示了使用三联抗生素糊剂和矿物三氧化物凝聚体对大型根尖周病变进行非手术牙髓病治疗的情况。
