简要总结
The aim of this randomized split-mouth design clinical trial is to clinically evaluate the effectiveness of diode laser in the healing of donor site of palate in free gingival graft.
详细描述
Free gingival graft is the most predictable and successful method for increasing the width of keratinized tissue around teeth/dental implants and vestibular deepening. However, patient discomfort during the healing time is a major disadvantage of this procedure. Several methods have been introduced to accelerate the healing time and reduction of patient's pain during first days after surgery. Low-level lasers have shown promising results in biostimulation of cell growth and differentiation in cultures. However, there are lack of well designed double blind placebo controlled randomized controlled clinical studies evaluating the effects of Low-level laser therapy in acceleration of wound healing and pain relief of patients undergoing free gingival grafts.

结局指标
主要结局
degree of epithelialization
时间窗: At day 21
3% hydrogen peroxide (H2O2) was applied to the wound by a sterile gause to see the bubbling * Complete epithelialization: bubble was not seen * Partial epithelialization: bubbles were seen in lesser than half of donor site * No epithelialization: bubble were seen in more than half of donor site
次要结局
- Visual analogue scale (VAS) pain score(at day 14)
- Clinical healing(at day 21)
