NCT02831374.

Study name	Effectiveness of platelet rich plasma in wound healing
Methods	Randomised parallel assignment
Participants	40 participants
Interventions	PRP gel
Outcomes	Primary outcome measures Assessment of pain (time frame: 1 week). Postoperative pain was assessed using a 10‐point visual analogue scale with a score of 0 equals 'no pain' and 10 equals 'very severe pain'. Assessment of facial swelling (time frame: 1 week). Facial swelling was assessed by modification of Schultze‐Mosgau and colleagues method, which involved measuring the length from the tragus to the oral commissure and tragus to the pogonion. The arithmetic sum of the 2 measurements was considered as facial swelling at the time point. Assessment of trismus (time frame: 1 week). The maximum distance between the maxillary central incisors and the mandibular central incisors was taken as mouth opening. The difference between postoperative and preoperative mouth opening value was considered as trismus. Assessment of soft‐tissue healing (time frame: 1 week). Assessment of soft‐tissue healing was based on the criteria given by Landry and colleagues and Gonshor. Assessment of bone healing (time frame: 1 week). Third molar sockets were assessed radiographically for bone healing by modification of the Kelley's method as described by Olufemi and colleagues.
