Regenerative Surgical Management of an Endodontic Periodontic Lesion of the Mandibular Molar Combined With External Inflammation Root Resorption.

Endo-perio lesions are lesions involving pulp tissue with periodontal tissue. The bacterial infection of the pulp can spread to the furcation area through the accessory canal, causing damage to the furcation area. Regeneration therapy has good success when performed with flap surgery and is performed in cases of Grades I and II furcation involvement.
