Ozonized gel vs low-level laser for healing gums after gingivectomy

Effect of Ozonized Gel Compared to Photobiomodulation Therapy on Wound Healing Following Surgical Gingivectomy : A Randomized Controlled Clinical Trial

Not applicable Interventional Alexandria University · NCT07234994

Researchers will see if applying ozonized gel or using low-level laser (photobiomodulation) after gingivectomy helps adults heal faster and with less pain.

What this trial studies

This randomized controlled trial will compare wound healing after surgical gingivectomy across three groups: ozonized hydrogel application, photobiomodulation with a 635 nm diode laser, and a control group receiving standard postoperative care. Forty-eight wound sites will be randomized equally, with treatments given immediately post-op and repeated on days 3, 7, and 14, and clinical follow-ups on days 3, 7, 14, and 28 to record healing and pain. Outcome measures include clinical wound healing assessments, patient-reported pain and feedback, and routine postoperative examinations. Adults aged 18–40 with good oral hygiene and adequate keratinized tissue are eligible, while smokers, pregnant women, and those with systemic conditions affecting healing are excluded.

Who should consider this trial

Good fit: Adults 18–40 indicated for surgical gingivectomy with good oral hygiene, adequate keratinized tissue, non-smokers, and able to follow postoperative instructions are ideal candidates.

Not a fit: Smokers, pregnant patients, people with systemic diseases affecting wound healing, or those with poor oral hygiene are unlikely to match the trial's eligibility and may not benefit.

Why it matters

Potential benefit: If successful, the preferred treatment could shorten healing time and reduce postoperative pain after gingivectomy.

How similar studies have performed: Previous dental research has reported that both ozonized products and photobiomodulation can aid tissue repair and pain control, but direct head-to-head comparisons after gingivectomy are limited.
