Guided tissue regeneration in the management of severe periodontal-endodontic lesions

Diagnosis of combined periodontal-endodontic lesions can prove difficult and frustrating. They are often characterised by extensive loss of periodontal attachment and alveolar bone, and their successful management depends on careful clinical evaluation, accurate diagnosis, and a structured approach to treatment planning for both the periodontic and endodontic components. Recent advances in regenerative periodontics have led to improved management of periodontal-endodontic lesions. This paper reviews the management of such lesions in light of these recent advances and illustrates this through reports of two patients who had severe periodontal involvement.
