Effect of concentrated growth factor (CGF) on short-term clinical outcomes after partially impacted mandibular third molar surgery: A split-mouth randomized clinical study

Purpose: The aim of this study was to evaluate the effectiveness of concentrated growth factor(CGF) on soft tissue healing and postoperative side effects following third molar surgery. Methods: This study was designed on 60 patients as a randomized single-blind clinical trial. The predictor variable was the implementation of CGF fibrin matrix, which was categorized as CGF and non-CGF. The primary outcome variable of the study was the healing of soft tissue around the extraction socket. The secondary outcome variables were pain, swelling and trismus. Data were analyzed using the non-parametric Brunner and Langer model. Statistical significance was set at P < .001. Results: Sixty patients (39 female, 21 male; mean age 25.82) with impacted mandibular third molars participated in the study. Statistical analysis revealed that there were significant differences between the control and test groups with regard to soft tissue healing, postoperative pain, swelling, and trismus (P < 0.001). Conclusion: The application of CGF accelerates soft tissue healing and is beneficial in minimising postoperative side effects, particularly pain, swelling and trismus, after extraction of mandibular third molars.
