About

The goal of this clinical trial is to learn if platelet-rich fibrin (PRF), a substance made from a person's own blood, helps preserve the bone in the jaw after tooth extraction in adults. The main questions it aims to answer are:

Does PRF help reduce the loss of bone height after tooth removal? Does PRF improve how much of the socket fills with new bone?

Researchers will compare extraction sites treated with PRF to untreated sites in the same person to see if PRF helps preserve more bone.

Participants will:

Have two teeth removed on opposite sides of the mouth Receive PRF in one socket, while the other socket is left to heal naturally Undergo 3D X-ray scans (CBCT) right after extraction and again 3 months later

This study will help researchers understand if using PRF alone can improve healing and reduce bone loss after tooth extraction.

Enrollment: 12 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Participants were eligible for inclusion if they met the following criteria:

• Age ≥ 18 years

• Smoking fewer than 10 cigarettes per day

• Presence of adequate bony support (≥ 60%)

• Indications for bilateral tooth extraction

• Patients classified as ASA I or II (American Society of Anesthesiologists).

• No systemic conditions known to impair healing, including the following:

  • Use of bisphosphonates
  • Anticoagulant or antiplatelet therapy
  • History of head and neck radiotherapy
  • Chronic use of NSAIDs or corticosteroids

Exclusion criteria

Patients were excluded if they met any of the following conditions:

• ASA classification III or IV
• Pregnancy or lactation
• Presence of active infection at the surgical site or need for medications beyond standard analgesics
• Presence of chronic lesions at the extraction site (patients requiring curettage of the lesion were included; those with acute infection requiring antibiotics were excluded).

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: Double Blind

---

12 participants in 2 patient groups

Split-Mouth PRF Arm

Experimental group

Description:

Each participant will have two symmetrical tooth extractions. One socket will be randomly assigned to receive platelet-rich fibrin (PRF), and the contralateral socket will serve as a control, healing naturally without any graft material. This split-mouth design allows each participant to act as their own control. Radiographic assessments using cone-beam computed tomography (CBCT) will be conducted at baseline and 3 months to measure bone height, ridge width, and socket fill.

Biological: Platelet-rich fibrin (PRF)

Split-Mouth Control Arm

No Intervention group

Description:

Each participant will have two symmetrical tooth extractions. One socket will be randomly assigned to receive platelet-rich fibrin (PRF), and the contralateral socket will serve as a control, healing naturally without any graft material. This split-mouth design allows each participant to act as their own control.
