Recep Tayyip Erdogan University42 enrolled

Overview

This study evaluates the effects of two different blood products obtained from the patient's own blood (Concentrated Growth Factor \[CGF\] and Platelet-Rich Plasma \[PRP\]) on healing after wisdom tooth extraction. The aim is to determine whether applying these materials to the extraction area reduces postoperative pain, facial swelling, and the risk of dry socket compared to standard healing.

This prospective, randomized, controlled clinical trial compares the efficacy of autologous platelet concentrates in reducing postoperative sequelae following the surgical extraction of impacted mandibular third molars. A total of 42 patients were randomly assigned to one of three groups: Control Group: Standard surgical extraction without additional biomaterials. CGF Group: Standard extraction followed by the placement of a CGF clot into the extraction socket. PRP Group: Standard extraction followed by submucosal injection of PRP. The primary outcome measured is postoperative pain (Visual Analog Scale) on postoperative days 1, 3, and 7. The secondary outcomes include facial swelling (linear measurements) on postoperative days 1, 3, and 7, and the incidence of alveolar osteitis (dry socket).

Outcomes

Primary Outcomes

Postoperative Pain

Assessed using a Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (worst pain imaginable).

Time frame: Postoperative days 1, 3, and 7.

Secondary Outcomes

Facial Swelling

Measured using linear distances between specific facial landmarks (tragus to mouth commissure, tragus to pogonion, lateral canthus to mandibular angulus) to evaluate edema.

Time frame: Preoperative and Postoperative days 1, 3, and 7.

Incidence of Alveolar Osteitis

Evaluated based on clinical signs such as loss of blood clot, intense throbbing pain, and halitosis (dry socket).

Time frame: Postoperative days 1, 3, and 7
