About this study
Official title: Regenerative Endodontic Procedure of Immature Permanent Teeth With Apical Periodontitis Using Platelet-rich Fibrin : A Pilot Randomized Controlled Trial
This study evaluates the clinical effect of regenerative endodontic procedure using PRF in immature permanent teeth with apical periodontitis. Half of participants will receive the PRF instead of blood clots in the regenerative endodontic procedure, while the other half will receive a blood clots in the regenerative endodontic procedure.
Read the detailed description
The conventional method of regenerative endodontic procedure using a blood clot as scaffold materials has shown successful results. However, it is very difficult to induce bleeding and place mineral trioxide aggregate over a blood clot. Platelet-rich fibrin (PRF), a second-generation platelet concentrate. PRF is a matrix of autologous fibrin containing a large quantity of platelets, growth factors and leukocytes. PRF preparation technique is very simple, inexpensive and doesn't require any chemical agents. The purpose of this study is to test the hypothesis that the use of PRF in regenerative endodontic procedure of immature permanent teeth with apical periodontitis will accelerate periapical bone healing and stimulate the root maturation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PRFDevice
Also called mineral trioxide aggregate
Regenerative Endodontic Procedure with PRF: autologous PRF will be used instead of blood clot in the second vist.
| Study group | Role | What they receive |
|---|---|---|
| Regenerative Endodontic Procedure + PRF | Experimental | Visit 1: root canal dressing with triple antibiotic paste. Visit 2: a 5 ml sample of whole blood was drawn intravenously from the patient's forearm. The blood sample is centrifuged at 400 g for 10 min. The prepared PRF membrane is cut into segments, the fragments are placed into the canal space. The coronal is sealed mineral trioxide aggregate and composite resin. Receives: Device: PRF |
| Regenerative Endodontic Procedure | No intervention | Regenerative Endodontic Procedure Visit 1: root canal dressing with triple antibiotic paste. Visit 2: Blood clot formation is induced in the root canal after disinfection. No PRF was used in this group. Then the canal access is sealed with mineral trioxide aggregate and composite resin. |

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evidence of periapical healing (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 5 Sep 2021; AzTrials last refreshed its copy on 7 Nov 2026.
