Flap versus flapless removal of a partially impacted lower wisdom tooth
Official title: Comparison of Postoperative Pain and Swelling in Flap Versus Flapless Technique for Surgical Removal of Partially Impacted Mandibular Third Molars: A Randomized Controlled Trial
Run by Watim Medical & Dental College · NCT07247929 · Data updated 2026-11-12
This trial will test whether a flapless technique causes less pain and swelling than the traditional flap method for adults (18–45) having a partially impacted lower wisdom tooth removed.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–45 with a partially impacted mesioangular mandibular third molar, a second episode of pericoronitis, ipsilateral swelling, and no radiographic periodontal bone loss are ideal candidates.
✕Probably not a fit
Patients with diabetes, bleeding disorders, immunocompromised status, acute periapical infection or severe trismus, or fully impacted/other angulated molars are unlikely to benefit from or be eligible for this comparison.

What this trial studies
This randomized controlled trial will assign 160 adults with partially impacted mesioangular mandibular third molars to either a flap or a flapless extraction technique. Pain will be recorded on a 10-point visual analogue scale and facial swelling will be measured with standardized anthropometric measurements, with primary comparison on the second postoperative day. All procedures will be performed by a single surgeon to minimize operator variability. The trial excludes patients with systemic conditions, bleeding disorders, acute infections, or severe trismus to reduce confounding factors.
Why it matters
Potential benefit: If successful, the flapless approach could reduce early postoperative pain and facial swelling, helping patients recover faster after lower wisdom tooth removal.
How similar studies have gone: Previous small trials and case series have suggested flapless extraction may reduce early pain and swelling in some patients, but results across studies are mixed and not definitive.
