Plain English summary of protocol

Background and study aims
Some physiological changes may occur following tooth extraction, and the symptoms may affect the patient’s quality of life. Many techniques have been developed to improve pain and soft tissue healing. The aim of this study is to compare the pain and early soft tissue healing characteristics of extraction sites treated with leukocyte-and-platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF).

Who can participate?
Patients aged 18–50 undergoing tooth extraction

What does the study involve?
Participants are randomly allocated into three groups to be treated with advanced platelet-rich fibrin, leukocyte platelet rich fibrin, or no additional treatment after tooth extraction. Afterwards, participants in each group are assessed for pain, number of analgesics used, and early soft tissue healing.

What are the possible benefits and risks of participating?
The treatment may accelerate soft tissue healing and decrease pain. Some participants may feel unwell or faint during or after the procedure.

Where is the study run from?
Umm Al-Qura University (Saudi Arabia)

When is the study starting and how long is it expected to run for?
October 2019 to April 2020

Scientific titleThe effectiveness of advanced platelet-rich fibrin in comparison with leukocyte-platelet-rich fibrin on outcome after dentoalveolar surgery
Study objectivesAdvanced platelet-rich fibrin is more effective than leukocyte platelet-rich fibrin in decreasing post-extraction pain and early soft tissue healing.
Ethics approval(s)Approved 19/01/2020, Umm Al-qura University Faculty of Dentistry Institutional Review Board (Umm Al-Qura University, Makkah, 24373, Saudi Arabia; +966 (0)125270000; irb.uqudent@uqu.edu.sa), irb: 143-19
Health condition(s) or problem(s) studiedPain and soft tissue healing after tooth extraction
InterventionPatients are divided by stratified randomization into three groups:
Group Ӏ: 20 patients treated with advanced platelet-rich fibrin after tooth extraction
Group ӀӀ: 20 patients treated with leukocyte platelet-rich fibrin after tooth extraction
Group ӀII: 20 patients receive no additional treatment

Afterwards, patients in each group are assessed for post-extraction pain on the first and second day by VAS, the number of analgesics taken after 6, 12, 18, 24 hours, and early soft tissue healing at the first and second week by LWHI.

Follow up is weekly for 2 weeks.
