Nonsurgical management of a large periapical lesion using aspiration in combination with a triple antibiotic paste and calcium hydroxide

Iranian Endodontic Journal, 2010
Persistent microorganisms in the root canal are known to cause endodontic treatments failure. Overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions.
