Study summary

In this study, it was aimed to investigating and comparing the postoperative effects of leukocyte- and platelet-rich fibrin (L-PRF) and advanced platelet-rich fibrin (A-PRF) in terms of pain, swelling on the cheek, and trismus after mandibular third molar surgery. The study included a total of 27 patients with bilateral impacted mandibular third molar which surgically operated at different times. Patients were evaluated in two randomly separated groups. For the first group; A-PRF and for the second group; L-PRF was applied into the tooth socket. The outcomes variables were; pain, swelling, the number of analgesics taken, and trismus. These variables were also assessed on the basis of; 1st, 2nd, 3rd and 7th days following the operation.

What researchers measure

Primary outcomes

  1. Pain Scores Evaluted

    For the postoperative period, the pain scores change was evaluated with the help of the visual analog scale (VAS) ranging from 0 (no pain) to 10 (most severe pain).

    Time frame: 1st day after the operation.

  2. Pain Scores Evaluted

    For the postoperative period, the pain scores change was evaluated with the help of the visual analog scale (VAS) ranging from 0 (no pain) to 10 (most severe pain).

    Time frame: 2nd day after the operation.

  3. Pain Scores Evaluted

    For the postoperative period, the pain scores change was evaluated with the help of the visual analog scale (VAS) ranging from 0 (no pain) to 10 (most severe pain).

    Time frame: 3rd day after the operation.

  4. Pain Scores Evaluted

    For the postoperative period, the pain scores change was evaluated with the help of the visual analog scale (VAS) ranging from 0 (no pain) to 10 (most severe pain).

    Time frame: 7th day after the operation.

Secondary outcomes

  1. Number of Analgesics Taken by the Patients

    Time frame: Each patient was evaluated on the 1st, 2nd, 3rd, and 7th days after the operation.

  2. Trismus

    Trismus was assessed by measuring the distance between the mesioincisal corner of the maxillary and mandibular right incisors while mouth was fully opened

    Time frame: Each patient was evaluated in order to obtain measurements on the 1st, 2nd, 3rd, and 7th days after the operation.

  3. Swelling on the cheek

    In order to record swelling, a modification of the tape measurement method

    Time frame: Each patient was evaluated in order to obtain measurements on the 1st, 2nd, 3rd, and 7th days after the operation.
