The primary outcomes assessed were pain and analgesic use, swelling, hemostasis, trismus, infection and dry socket, inferior alveolar nerve injury and paresthesia, fever, patient-reported outcomes, and satisfaction.

Clinical studies involving healthy adults undergoing third molar extraction with or without CGF application were considered eligible based on population, intervention, comparison, outcomes, and study design framework.
