Forty two patients with necrotic anterior and premolar teeth with or without periapical radiolucency were diagnosed clinically and radigraphically was endodontically treated in tow visits, at first visit mechanical preparation was done then Intracanal medicament was injected in root canals. The patients were divided into 3 equal groups of 14 patients each according to the intracanal medication used: A. group A: ledermix intracanal medicament. B. group B: Calcium hydroxide intracanal medicament. C. group C: No intracanal medicament used.
