Endodontic treatment's primary purpose is to treat pulpal and periapical pathosis (1).For dental health care practitioners, especially endodontic experts, an inflammatory apical or peri-radicular lesion in an already obturated tooth that persists or progresses is a serious concern. According to different research populations, this post-treatment apical periodontitis/post endodontic diseases prevalence varies from 16 to 65 percent (2). The presence of microorganisms throughout the root canal system and/or in the apical region has been suggested as the major reason, while other factors such as presence of cysts, cystic components like cholestrol crystals, persistent inflammatory activities were also been associated (2). Nonsurgical or surgical retreatment is always the primary line of treatment (3). Retreatment and periapical surgery have been suggested as treatment modalities with different levels of success rates (4). Intentional replantation is advocated as an alternative way for treating post-endodontic pathology or failed non-surgical retreatment and also when we face a difficulty in surgically approaching the site, need to not damage the innate anatomical structures, or to improve operational efficacy(5).
