NCT ID NCT05935306
First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time
Summary
This trial asks whether photobiomodulation — a type of low-level laser therapy — can lessen pain and swelling after endodontic (root-end) surgery. Thirty-four adults needing surgery on an upper tooth will be randomly assigned to receive either the laser treatment or a sham procedure, alongside standard ibuprofen. Pain, swelling, and healing will be tracked over a week, with follow-up X-rays at one and three months.
