Adjunctive role of photodynamic therapy in the nonsurgical endodontic retreatment of a molar with grade II furcation involvement

Abstract

Endodontic therapy has a high survival rate, but in cases of post-treatment pathosis, retreatment may be required. This case report presents a similar case of endodontic failure which resulted in a coexistent periradicular-periodontal lesion. The case was managed by nonsurgical endodontic retreatment followed by photodynamic therapy in the periodontal region. Satisfactory results were obtained when the case was followed up clinically and radiographically for 18 months.
