What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Antibiotic-enriched Platelet-Rich Fibrin (PRF)Biological

    Platelet-rich fibrin prepared with the addition of antibiotic prior to centrifugation and applied into the mandibular third molar extraction socket to provide local antibiotic delivery.

  • Platelet-Rich Fibrin (PRF)Biological

    Standard platelet-rich fibrin prepared without antibiotic addition and applied into the mandibular third molar extraction socket.

Study groupRoleWhat they receive
Test Group - Antibiotic and PRFExperimentalParticipants will receive platelet-rich fibrin prepared with the addition of antibiotic prior to centrifugation. The antibiotic-enriched PRF clot will be placed into the mandibular third molar extraction socket to provide local antibiotic delivery at the surgical site.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of postoperative infection

    Occurrence of postoperative infection following mandibular third molar surgery, assessed through clinical examination based on the presence of signs and symptoms of infection (e.g., purulent discharge, erythema, fever, or need for additional antibiotic therapy).

    Measured: Up to 7 days after surgery

  2. Facial swelling qualitative analysis

    Change in facial volume from baseline, assessed by three-dimensional facial scan superimposition and expressed as colorimetric variation between the preoperative and postoperative scans.

    Measured: Change from baseline (before surgery) at 2 day after surgery and at 7 days after surgery

  3. Facial swelling quantitative analysis - volumetric differences

    To compare postoperative facial swelling between treatment groups using quantitative three-dimensional analysis based on volumetric differences. Facial volume changes will be measured in cubic centimeters (cm³) through three-dimensional facial scan superimposition.

    Measured: Change from baseline (before surgery) at 2 day after surgery and at 7 days after surgery

  4. Facial swelling quantitative analysis - linear differences

    To compare postoperative facial swelling between treatment groups using quantitative three-dimensional analysis based on linear measurements. Facial changes will be assessed by evaluating linear differences (mm) between preoperative and postoperative three-dimensional facial scans.

    Measured: Change from baseline (before surgery) at 2 day after surgery and at 7 days after surgery

Secondary outcomes (2)
  1. Trismus analysis

    To compare postoperative limitation of mouth opening between treatment groups following mandibular third molar surgery. Trismus will be assessed by measuring maximum mouth opening (MMO) in millimeters (mm).

    Measured: Change from baseline (before surgery) at 2 day after surgery and at 7 days after surgery

  2. Pain analysis with Visual analogue scale (VAS)

    To compare postoperative pain intensity between treatment groups following mandibular third molar surgery. Pain will be assessed using a Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst possible pain).

    Measured: Change from baseline (before surgery) at 2 day after surgery and at 7 days after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Antibiotic-enriched Platelet-Rich Fibrin (PRF) and Platelet-Rich Fibrin (PRF) in people with Facial Swelling and Tooth Position Anomalies, run by Amerigo Giudice at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 10 exclusion criteria. 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: under way, not looking for participants, as of the sponsor's last update on 20 Aug 2026. 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 Italy. 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?

This study is still under way. Results are not available in the source record yet.

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?

Incidence of postoperative infection (time frame: Up to 7 days after surgery). The study lists 4 primary outcomes in all. 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 20 Aug 2026; AzTrials last refreshed its copy on 8 Nov 2026.
