The Clinical Impact of E-PRF and H-PRF on Healing After Mandibular Third Molar Surgery
- Conditions
- Platelet-Rich Fibrin
- Interventions
- Biological: H-PRF (Horizontal-platelet rich fibrin)Biological: E-PRF
- Registration Number
- NCT05772975
- Lead Sponsor
- Amila Haskic
- Brief Summary
This clinical trial aims to compare the effect of platelet concentrates E-PRF and H-PRF on soft and hard tissue healing in healthy individuals after lower third molar surgery. The main questions it aims to answer are:
Do E-PRF and H-PRF reduce complications after third molar surgery? Do E-PRF and H-PRF improve soft tissue healing after third molar surgery? Do E-PRF and H-PRF improve hard tissue healing after third molar surgery? Participants will be divided into 2 study groups and one control group. Third molar surgery will be performed according to standard protocol. In study groups, dentoalveolar defects will be filled with E-PRF and H-PRF which are products of centrifugation of the patient's blood without additives. Soft tissue and hard tissue healing will be compared between the groups.
- Detailed Description
A Randomized, Three Parallel Arms Clinical Trial. The primary objective is to assess the clinical impact of E-PRF vs H-PRF vs Control on the soft tissue healing and post-op discomfort and complications after mandibular third molar surgery between the three groups during the healing period of 7 days.
The secondary objective is to compare bony healing between the three groups over three months using an Orthopantomograph (OPG) X-ray.
All subjects from the University of Sarajevo Faculty of Dentistry with Dental Clinical Center. Subjects that are coming for the removal of impacted mandibular third molars and match the inclusion criteria will be told about the research and offered the opportunity to participate.

Group Intervention Description H-PRF H-PRF (Horizontal-platelet rich fibrin) After the impacted mandibular third molar has been surgically removed H-PRF is placed in the dentoalveolar defect PRF made with horizontal centrifuge and the wound is primarily closed. E-PRF E-PRF After the impacted mandibular third molar has been surgically removed E-PRF is placed in the dentoalveolar defect and the wound is primarily closed.
- Primary Outcome Measures
Name Time Method The impact of E-PRF vs H-PRF vs Control on bone regeneration 3 months Bone healing will be evaluated by comparing digital OPGs i.e. radiographic bone densitiy profiles in extraction sockets will be compared.
The impact of E-PRF vs H-PRF vs Control on soft tissue healing 7 days Soft tissue healing evaluation will be done by modified Landry, Turnbull and Howley healing index. For each post-extraction site, the following parameters will be evaluated by dichotomic scale (0/1): tissue color, response to palpation, presence of granulation tissue, epithelialization of incision margins and suppuration.
- Secondary Outcome Measures
Name Time Method The impact of E-PRF vs H-PRF vs Control on postoperative trismus 7 days The primary outcome is to asses the percentage of trismus after mandibular third molar surgery in study groups vs control. Trismus will be measured as the distance between the upper right and lower right central incisors during maximum mouth opening using digital caliper.
The impact of E-PRF vs H-PRF vs Control on periodontal pocket depth 3 months Pocket depth will be measured using a periodontal probe taken from the margin of the gingiva to the base of the pocket along the distal surface of the mandibular second molar at three points: distobuccal, mid-distal, distolingual.
The impact of E-PRF vs H-PRF vs Control on postoperative pain 7 days The primary outcome is to asses the level of pain after mandibular third molar surgery in study groups vs control. A visual analog scale (VAS) will be used to evaluate postoperative pain. A 10-point VAS with a score of 0 equals "no pain" and 10 equals "very severe pain" will be used to asses subjective pain. Patients will be asked to record number of analgesic taken during the monitoring period of 7days.
The impact of E-PRF vs H-PRF vs Control on postoperative swelling 7 days The primary outcome is to asses the percentage of swelling after mandibular third molar surgery in study groups vs control. Facial swelling will be evaluated by measuring 3 facial distances: from the tragus to pogonion (TPO), tragus to labial commissure (TCO), and angulus mandibulae to lateral canthus (ACA).
