Free Gingival Graft Adjunct With Low Level Laser Therapy

Abant Izzet Baysal University30 enrolled

Overview

The present placebo-controlled parallel design clinical study was planned to determine the effect of low level laser therapy on clinical periodontal conditions and dimensions of free gingival graft as well as postoperative pain levels in the surgical area.

Background: Shrinkage of the free gingival graft (FGG) and patient's discomfort during healing period are important concerns. Therefore, this study aimed to evaluate the effect of low level laser therapy (LLLT) in terms of enhancing wound healing, reducing graft shrinkage and postoperative pain. Methods: Thirty patients were randomly assigned to receive either FGG+ LLLT (test, n = 15) or FGG + placebo LLLT (control, n = 15). In the test group, a diode laser (aluminum-gallium-arsenide, 810 nm, 0.1 W, continuous mode, time of irradiation:60 s, energy density: 6 J/cm2, spot size:0.5 cm) was applied immediately after the FGG surgery and 1,3,7, and 14 days later. The control group received the same sequence of irradiation with the laser-off. Comparison of the graft surface areas between groups at 1st, 3rd and 6th months were made with an image-analyzing software. Complete wound epithelization, visual analogue scale (VAS) pain score of recipient site and the number of analgesic used were evaluated after the surgery.

low level laser therapy was utilized adjunct with free gingival graft.

Clinical examinationOTHER

The shrinkage of the graft area was calculated according to the differences between the graft area at baseline, 1st, 3rd, and 6th months. Epithelization was determined via bubbling test by using 3% hydrogen peroxide (H2O2) at 7, 14, 21, and 28 days after surgery.

Outcomes

Primary Outcomes

Graft shrinkage

The shrinkage of the graft area was calculated according to the differences between the graft area at baseline, 1st, 3rd, and 6th months.

Time frame: 1-, 3-, and 6-months after FGG surgery

Secondary Outcomes

Epithelization

Epithelization was determined via bubbling test by using 3% hydrogen peroxide (H2O2). This test was carried out at 7, 14, 21, and 28 days after surgery.

Time frame: 7, 14, 21, and 28 days after FGG surgery
