Bone Regeneration Using PRF After Cyst Enucleation (PRF-Bone)

February 14, 2026 updated by: Lamees Fozi Alareeki, Sana'a University

Clinical Efficacy of Platelet-Rich Fibrin in Osseous Regeneration After Cystic Enucleation

This randomized controlled clinical trial aims to evaluate the clinical efficacy of autologous platelet-rich fibrin (PRF) in promoting osseous regeneration following cystic enucleation in the jaws. The study will assess bone healing outcomes and compare PRF application with conventional management methods.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is designed as a randomized controlled clinical trial to evaluate the effectiveness of autologous platelet-rich fibrin (PRF) in enhancing bone regeneration after cystic enucleation in the jaws.

PRF is an autologous biomaterial rich in growth factors that may enhance bone healing and tissue regeneration. Participants undergoing cystic enucleation will be randomly assigned to either a PRF-treated group or a control group receiving conventional treatment without PRF.

Clinical and radiographic assessments will be performed to evaluate bone regeneration, healing rate, and postoperative outcomes. If PRF demonstrates significant improvement in osseous regeneration, it may represent a minimally invasive and cost-effective alternative to traditional bone grafting procedures.

Ethical approval will be obtained from the Ethical Committee of the Faculty of Medicine and Health Sciences, Sana'a University, Yemen.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients diagnosed with odontogenic cysts requiring surgical enucleation.
  • Presence of a postoperative osseous defect in the jaws after cyst enucleation.
  • Age ≥ 18 years.
  • Systemically healthy patients (ASA I or II).
  • Patients willing to participate and sign informed consent.

Exclusion Criteria:

  • Patients with systemic diseases affecting bone healing (e.g., uncontrolled diabetes, osteoporosis).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: PRF Group
Participants undergoing cystic enucleation in the jaws will receive autologous Platelet-Rich Fibrin (PRF) placed into the osseous defect immediately after surgical enucleation.
Biological: Autologous Platelet-Rich Fibrin (PRF)
Autologous platelet-rich fibrin (PRF) prepared from the participant's own venous blood will be placed into the osseous defect immediately after cystic enucleation. PRF will be prepared using standard centrifugation protocols and applied to promote bone regeneration.
Active Comparator: Control Group
Participants undergoing cystic enucleation of jaw cysts will receive conventional surgical management without the application of platelet-rich fibrin (PRF). The osseous defect will be left to heal naturally following standard enucleation and wound closure procedures.
Procedure: Conventional Surgical Management
Conventional cystic enucleation will be performed without the use of platelet-rich fibrin (PRF). The osseous defect will be managed according to standard surgical protocol and allowed to heal naturally.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Radiographic bone regeneration in cystic defects following enucleation
Time Frame: 6 months after surgery
The amount of bone regeneration will be evaluated radiographically using CBCT imaging to measure the percentage of defect fill and bone density changes at 6 months postoperatively.
6 months after surgery
