Abstract Introduction: The success of a combined periodontal and endodontic lesion depends on the elimination of both these disease processes. In the case of a combined endo-perio lesion, endodontic therapy results in healing of the endodontic component of involvement, while the prognosis of teeth would finally depend on the healing of the periodontal structure. Treatment: This case report evaluates the efficacy of autologous fibrin glue and bone graft, that is, sticky bone in the management of bone defects associated with endo-perio lesion. The endo-perio lesion is first treated endodontically, followed by periodontal therapy. Conclusion: The patient was kept on follow-up for 9 months, and satisfactory results in terms of bone fill and reduction in pocket depth were obtained. Take-away Lessons: The sticky bone enhances regeneration in treatment of endo-perio lesions.
