CORRECTION OF A LARGE PERIRADICULAR LESION AND MUCOSAL DEFECT USING COMBINED ENDODONTIC AND PERIODONTAL THERAPY - A CASE-REPORT

The successful treatment of a large endodontically induced periradicul ar defect and soft tissue fenestration by combined endodontic and peri odontal therapy is described. Endodontics was performed on the mandibu lar left central incisor, the apex was resected and a retrograde amalg am was placed. The defect was thoroughly debrided and the exposed roof surface was planed with curettes. Demineralized freeze-dried bone all ograft and a nonresorbable membrane were placed over the defect and th e exposed roof surface. The membrane was removed in 6 months and there appeared to be bone regeneration with complete closure of the soft ti ssue fenestration. Endodontic therapy in combination with guided tissu e regeneration and bone grafting may provide another modality of treat ment for endodontically related hard and soft tissue defects.
