Brief Summary

The fear of oral surgeries is mostly dedicated to pain and swelling in the following days. It is not surprising, that it is of high interest to do anything to reduce these consequences. Maybe this is a reason, why using platelet concentrates in oral health rehabilitation has become common in the last couple of years. Less swelling, less pain, quicker healing. The aims of the present study are to determine the effect of a platelet rich fibrin on postsurgical inflammatory complications and patient-centred outcomes and perceptions, in patients undergoing third molar extractions by split mouth technique. 25 medically healthy adults will be assigned to one of 2 groups (1 test- and 1 control group). This means due to the split mouth technique patients undergo a third molar extraction twice. The first time the patient will be randomly assigned to the test- or control group and the second time the patient will be in the other group (test or control group). The test groups socket will be filled with a PRF (platelet-rich fibrin)-Clot before suturing the wound during third molar surgery. As well, a blood count and coagulations values will be determined. The control group will be operated conventionally. Swelling will be measured at day 1, 3 and 7 post surgery by CBCT (cone-beam computed tomography) facial scan. Subjects will be examined clinically by examiners at the seventh day after surgery for postoperative complications. In addition, Visual analogue scores (VAS) on pain, swelling and bleeding will be obtained from the patients from day 0 through day 7. The present study will answer an important clinical question with regards to the recommendation of platelet-rich fibrin usage to prevent post-operative complications with third molar surgery and to recommend a platelet-rich fibrin, if required.

Outcome Measures

Primary Outcomes (1)

• Change in Swelling

  Buccal swelling will be measured manually as well as within creating a 3D face scan pre-surgical and at day 1, 3, 7 and 14 post-surgical. Scans will be superimposed and compared with Romexis software. Manual measurement: Lines between lateral corner of the eye- jaw angle, Tragus- outer Mouth corner, Tragus-Pogonion will be measured in mm and be compared pre-surgical and at day 1, 3, 7 and 14 post-surgical. longer lines suggest more swelling and a worse outcome.

  Pre-surgical and at day 1, 3, 7 and 14 post-surgical
