title: Revascularization of immature, nonvital permanent tooth using platelet-rich fibrin in children.
abstract: The purpose of this paper was to present a new approach wherein revascularization of the immature, nonvital permanent tooth was performed using platelet-rich fibrin (PRF) as a novel scaffold material. This was performed after disinfection of the root canal space using triple antibiotic paste followed by placing a PRF membrane in the root canal. The patient was followed up regularly at three-, six-, nine-, and 12-month intervals for review. After 12 months, clinical examination showed negative response to percussion and palpation tests but positive response to cold and electric pulp tests. Radiographic examination revealed continued thickening of the root dentinal walls, narrowing of root canal space, root lengthening, and closure of the root apex with normal periradicular architecture. However, more clinical research using large samples is necessary to prove it advantageous for regenerative endodontic therapy in children.
