Background and study aims
Impacted mandibular third molar extraction (also known as wisdom teeth removal) is one of the most common operations in oral and maxillofacial (mouth and teeth) surgery. Wisdom teeth grow at the back of the mouth and are the last teeth that come up through the gums, usually when people are young adults. Due to a lack of space, wisdom teeth can come through the gums on an angle causing them to be impacted. This usually means they need to be removed surgically. The operation consists of a small cut into the gum, extracting (removing) the tooth and then stitching up the area where the tooth was. Usually, the wound heals within a week or two however patients can experience some pain and are at risk of developing dry socket (a dull ache in the gum or jaw and a bad smell or taste coming from the area the tooth was removed). In order to encourage healing, platelet rich fibrin (PRF) has been suggested to be used on the tooth removal area. PRF is collected from the patients’ blood and is then processed to separate out the platelets in order to be placed on the site where the tooth was removed. PRF is thought to help increase healing and reduce the possibility of complications. The aim of this study is to see how well PRF helps reduce edema (swelling) and pain after impacted mandibular third molars surgery.
Who can participate?
Adults aged 17-27 who require the removal of their impacted mandibular third molar.
What does the study involve?
Participants give a small sample of blood which is then processed in order to separate out the PRF. Participants then undergo the removal of their wisdom teeth in their lower jaw. Both of the lower wisdom teeth (right and left) are removed according to the standard level of care. However, the right side tooth removal area receives PRF (placed on the area with dental forceps (tool)) and the left side tooth removal area does not receive PRF. Both tooth removal areas are stitched up. Participants receive follow up for seven days after the procedure where they are tested for pain and edema.
What are the possible benefits and risks of participating?
Participants may benefit from a shorter recovery time. There are no notable risks with participating however participants may feel some discomfort when giving the blood sample.

Scientific title | Effect of platelet rich fibrin on edema and pain following third molar surgery: A split mouth control study |
Study objectives | The aim of this study is to evaluate the efficacy of platelet-rich fibrine (PRF) on postoperative edema and pain after impacted mandibular third molar surgery. |
Ethics approval(s) | Local Ethical Committee of the Ankara University Faculty of Dentistry, 28/11/2011, ref: 25/1 |
Health condition(s) or problem(s) studied | Bilateral impacted third molars |
Intervention | Participants are selected based off their need for the removal of bilaterally (right-left) impacted mandibular third molars. Prior to the procedure, participants have blood collected. After placing the collected blood in a centrifuge for 12 minutes to separate the different components, the platelet rich fibrin (PRF) is collected and prepared to be applied to the patient. Participants then have both their left and right mandibular third molar extracted (done to the standard level of care). After extraction, participants receive PRF only to the right tooth extraction area. The left tooth extraction area does not receive anything. Both extraction sits are sutured. PRF is placed into the extraction area (tooth socket) using dental forceps. Participants are followed up for seven days after the study. Follow up involves measurements of participants pain and edema of the extraction areas and takes place at the Ankara University Dentistry faculty Oral and Maxillofacial Surgery department. For standardisation reasons, all measurements are done by the same surgeon. |
Intervention type | Procedure/Surgery |
Primary outcome measure | Pain is measured using a visual analogue scale (VAS) and Verbal rate scale (VRS) at 6 and 12 hours and 1, 2, 3 and 7 days after surgery. |
Secondary outcome measures | Edema is measured using a flexible ruler at baseline, 2 and 7 days. |
Overall study start date | 06/06/2011 |
Completion date | 19/10/2013 |
