About this study
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
Read the 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

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
injectable platelet rich fibrin augmented with Vitamin COther
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

Questions about this trial
What is this clinical trial studying?
A study testing injectable platelet rich fibrin augmented with Vitamin C in people with Periapical Periodontitis, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact wesam osama (01005540821, wessam_osama@dentistry.cu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Healing of periapical lesion (time frame: 1 year follow up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05585359, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Oct 2022.
