Brief summary
The purpose of the study is to investigate the effect of injectable platelet rich fibrin augmented with Vitamin C (ascorbic acid) in healing of chronic peri-apical lesion, by assessing it radiographically 2dimensionally and 3 dimensionally
Detailed description
all patients will be informed about the study through informed constant that will describe the natural of the study beside the potential risks of it. After accurate diagnosis clinically and radiographically, patients who will meet the eligibility criteria will be randomized. The standardized operating procedure of regenerative therapy requires two treatment visits. During the first appointment, infection is controlled and inflammation is relieved. Regenerative procedure and revascularization are accomplished during the second appointment. At the first visit, perioperative CBCT will be taken, access cavity with full mechanical preparation will be accomplished followed by application of double biotics paste for 3 weeks. At the second appointment the intra-canal medicaments will be removed then 10 ml of blood of whole venous blood will be drawn from the patient's forearm and transferred into two plain plastic test tubes without an anticoagulant and will centrifuge immediately u at 700 rpm for 3 minutes then liquid platelet rich fibrin layer will be taken with plastic syringe and according to the group of the patient that will be assigned, the patient will receive either the iprf alone or to be mix with Vitamin C and injected inside the canal. Collagen membrane will be placed over the iprf or iprf with Vitamin C then the tooth will be restored with resin filling material, the patients will be followed every 3 months for 1 year, at every follow up periapical radiograph will be taken with standardized bite block and after 1 year CBCT will aslo be taken with same parameter of the perioperative one t be compared and asses the reduction of the periapical lesions
Interventions
OTHERinjectable platelet rich fibrin augmented with Vitamin C
According to the amount of the injectable platelet rich fibrin that will be obtained after the centrifugation of blood, the amount of Vitamin C will be calculated to be; for each 1 ml of injectable platelet rich fibrin, 250 μg of Vitamin C will be mixed with the i-PRF and injected inside the canals using a plastic syringe with a 25-gauge needle that was placed 1mm short of the working length and will be withdrawn gradually while injecting till reaching the canal orifice

Masking description
The investigator will not be blinded due to the natural of the intervention and control which require blood withdrawal from the patient or to be mixed with the Vitamin C. * The patients and the outcome assessors are blinded to the intervention. * The patients will not be informed which technique of treatment will be used. * Data analyst will be blinded, he/she will receive data excel sheets with group A and group B
