Introduction: Treatment of necrotic tooth requires extensive management due to chances of fracture. Revascularization is the procedure for the management of immature necrotic tooth. Aim: The study was done to assess endodontic revascularization of the necrotic permanent anterior tooth with Platelet Rich Fibrin (PRF), Platelet Rich Plasma(PRP), and blood clot. Materials __ampersandsignamp; Methods: Thirty patients within the age range 15-25 years with the non-vital maxillary anterior tooth with or without periapical pathology and immature apex were selected and subjected to revascularization endodontics PRF, PRP and blood clot. Healing, root lengthening, apical closure and dentinal wall thickness was determined. Results: Group I used PRF, group II used PRP plus collagen and group III used blood clot. Group I had 6 males and 4 females, group II had 5 males and 5 females and group III had 4 males and 6 females. There was excellent healing seen in 80% in group I, 30% in group II and 10% in group III. Mann Whitney U test showed a significant difference (P 0.05) Conclusion: It was concluded from the present study that PRP had superior result in terms of apical closure, root lengthening and dentine wall thickness compared to the blood clot and PRF.
