Introduction: Regenerative Endodontic Treatment On Immature Teeth With Apical Periodontitis Is Rapidly Becoming An Accepted Treatment Alternative To Conventional Apexfication. Aim This Study Was Designed To Evaluate And Compare The Clinical And Radiographic Findings Of A Regenerative Procedure Using Platelet-rich ?brin (PRF) And Blood Clot In Immature Necrotic Permanent Teeth 12 Months After The Procedure Subjects &Methods: 30 Teeth Were Divided Into Two Groups 15 Participants In Each ,control Group Treated With A Standardized Revascularization Treatment Protocol Using Blood Clot As Scaffold And Study Group Used PRF As Scaffold And Monitored For Clinical And Radiographic Changes For 12 Month. Standardized Radiographs Were Collected At Regular Intervals, And Radiographic Changes Were Quantified.

Results: All Treated Teeth Showed A Statistically Significant Increase In Radiographic Root Thickness It Was 0.88ml In The Study Group Compared To 0.67ml In The Control Group With (p Value= 0.001)also There Was An Increase In The Mean Root Length Of The Treated Teeth Both Study Group And Control Group,(1.25 Ml In The Study Group Versus 0.98ml In The Control Group, P= 0.001).the Success Rate In Clinical Evaluation Criteria Post Intervention Was High With No Significant Difference Between The Study Versus The Control Group 86.7% (n=13) Of Study Groups To 80% (n=12) In The Control Group) Conclusion: Blood Clot And PRP Showed Comparative Results In Terms Of Periapical Healing, Dentinal Wall Thickening, Root Lengthening And Apical Closure
