Endodontic surgery was performed in combination with placement of an enamel matrix protein derivative. Methods: Endodontic surgery was performed, including root end resection at a 90° angle. Ultrasonic tips were used for retrograde preparation, and the retrograde cavity was sealed with zinc oxide–eugenol. The area was filled carefully with enamel matrix proteins. Sutures were removed after a 2-week healing period. Results: There were no symptoms of pain, inflammation, or discomfort at 18 months post-surgery. Radiographs showed complete healing of the periradicular lesion. Conclusions: Combining an enamel matrix protein derivative with conventional surgery may improve the clinical outcome of large endodontic lesions. Additional research is warranted.
