Postoperative Pain and Swelling After Flap vsFlapless Technique For Mandibular Third Molar Surgery

Impacted mandibular third molars frequently require surgical extraction, often involving mucoperiosteal flap elevation and bone removal. These steps may contribute to postoperative complications such as pain, swelling, and trismus. Minimally invasive alternatives, including flapless extraction, aim to reduce surgical trauma.

This study compares postoperative pain and swelling after flap versus flapless techniques in patients with partially impacted mesioangular mandibular third molars. Pain will be assessed using a 10-point Visual Analogue Scale (VAS), and swelling will be measured using standardized anthropometric facial measurements. A total of 160 participants will be randomized into two equal groups. All procedures will be performed by a single surgeon to reduce bias.
