Abstract
|
|
|
|
This study evaluated critical factors influencing the success of regenerative endodontic treatment for necrotic immature permanent teeth. The study enrolled patients who had regenerative endodontic treatment in a necrotic immature permanent tooth through 1-year follow-up. Possible explanatory variables related to the success rates for 46 teeth were age, gender, dental stage at the initial appointment, etiology, treatment information, and clinical and radiographic outcomes. The dental stage at the time of regenerative endodontic treatment did not influence the success rate. The success rate was significantly related to the etiology of the necrotic immature tooth. The success rate according to etiology decreased in the following order: dens evaginatus, caries, and trauma. There was also a significant difference according to the type of antimicrobial. The success rate was influenced by appropriate disinfection of the root canal system, provision of a scaffold, and coronal sealing. Above all, careful case selection is necessary for treating a necrotic immature permanent tooth, especially in cases of trauma.
