Treatment of Combined Endodontic-Periodontic Lesions Using Guided Tissue Regeneration: Clinical Case and Histology
Ghezzi, Carlo / Virzi, Mauro / Schupbach, Peter / Broccaioli, Alessandro / Simion, Massimo
The aim of this case report is to histologically evaluate periapical healing after combined endodontic-periodontic treatment. A maxillary left central incisor was treated with conventional endodontic therapy, followed by periodontal surgery. The facial bony defect was filled with a mixture of autologous bone and Bio-Oss. A resorbable membrane was used. Histology showed the presence of new cementum, ligament, and bone around the apex of the treated tooth. This finding was clinically associated with minimal residual probing depth and maximum attachment gain. This histologic report demonstrates the possibility of true regeneration in a case of severe periodontal attachment loss resulting from an endodonticperiodontic lesion.
