An Interdisciplinary Approach in the Management of Endodontic – Periodontal Lesion: Report of 2 Cases

The term endodontic-periodontal lesions have been used to describe lesions due to inflammatory products found in varying degrees in both pulp and periodontal tissues. These tissues share common embryonic derivation, vasculatures, lymphatic, neural pathways and microflora. As the tooth matures and the root is formed, three main avenues are created between pulp and periodontal ligament, i.e. dentinal tubules, lateral and accessory canals, and apical foramen. These are the pathways that may provide a means by which pathological agents pass between the pulp and periodontium, thereby creating the endo-perio lesion. Lateral canals play an important role in the spread of microbial products from pulp to periodontium. This paper reports two cases with a primary endodontic lesion with secondary periodontal involvement and their management by an interdisciplinary approach.
