Periapical lesions of endodontic origin are common pathological conditions affecting periradicular tissues. Microbial infection of pulpal tissues is primarily responsible for initiation and progression of apical periodontitis. The primary objective of endodontic therapy should be to restore involved teeth to a state of normalcy nonsurgically. Different nonsurgical management techniques, namely, conservative root canal therapy, decompression technique, method using calcium hydroxide, aspiration-irrigation technique, lesion sterilization and tissue repair therapy, active nonsurgical decompression technique, and the apexum procedure have been advocated...
