Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with Cairo RT1 or RT2 gingival recession in the mandibular anterior region and keratinized tissue width less than 2 mm seeking free gingival grafting.

Probably not a fit

Patients without insufficient keratinized gingiva or those not meeting the specific inclusion criteria may not benefit from these adjunctive treatments.

What this trial studies

This randomized, parallel-group study compares three approaches after free gingival graft surgery: the graft alone, graft plus 810-nm diode laser therapy, and graft with hyaluronic acid gel. Participants are adults with inadequate keratinized gingiva in the mandibular anterior region and are followed for six months to assess graft shrinkage, wound healing, clinical periodontal outcomes, pain, and quality of life. The laser group receives light treatment on the day of surgery and on postoperative days 1, 3, 7, and 14; the hyaluronic acid group receives gel application in addition to surgery. Outcomes include donor- and recipient-site pain, epithelialization, and standard periodontal measurements such as recession depth and keratinized tissue width. The study aims to determine whether these adjuncts improve healing, esthetics, and patient-reported outcomes compared with grafting alone.

Why it matters

Potential benefit: If successful, patients could experience faster healing, less graft shrinkage, reduced pain, and better esthetic and functional outcomes after gingival grafting.

How similar studies have gone: Previous studies in similar domains have shown mixed results; this trial tests whether targeted adjuncts can provide additional healing benefits after gingival grafts.
