Endo-Perio restorative continuum-a case report

The relationship between pulpal and periodontal diseases was described first by Simring and Goldberg in 1964.(1) It is caused due to cross infection between the root canal and periodontal ligament.(2) It occurs by the way of intimate vascular and anatomic connection between the pulp and periodontium.(3) Lesion of the alveolar bone and the periodontal ligament may originate either from the pulp tissue or the periodontium. Teeth with necrotic pulp shows periradicular bone loss secondary to endodontic pathosis. The goal of endodontic and periodontal therapy is to maintain the natural dentition and also to restore the lost periodontium. In this case routine endodontic treatment, periodontal flap surgery with crown lengthening followed by post and core and a full crown restoration was done in 45 and46. Thus the treatment of endodontic-periodontal lesion requires both endodontic and periodontal regenerative treatments.(4)
