很多文献描述了累及同一牙的牙髓、牙周病变病理学之间的关系。通常存在三种可能的情形:第一,牙髓病变伴随直接由牙髓病引起的牙周组织破坏;第二,进展性的牙周病变通过副根管或根尖组织累及牙髓;第三是所谓联合损害,即进行性的牙周病和牙髓病相互影响。 Many documents describe the relationship between the pulp involved in the same tooth and the pathology of periodontal lesions. There are usually three possible scenarios: first, endodontic lesions are associated with periodontal tissue destruction that is directly caused by endodontic disease; second, progressive periodontal disease affects pulp through the root canal or root apical tissue; third Is the so-called joint damage, that is, progressive periodontal disease and endodontic interaction.
