Aim: This case series study evaluated the application of Er;Cr:YSGG laser for a free gingival graft procedure and the effect of low level laser therapy on post surgical pain and wound healing.
Cases: 6 cases with mucogingival problems needing free gingival grafts were selected. First, the recipient site was anesthetized and de-epithelialization was done with a Er;Cr:YSGG laser. After tracing the palatal donor site with the laser, the graft was harvested. For root modification of the recipient tooth, conditioning of the dentin was done by the same laser. The inner side of graft was trimmed by the laser before suturing at the recipient site. After final adaptation of the grafts and suturing process, the recipient and donor sites were irradiated by therapeutic laser for reduction of post surgical complications.
Results: All patients reported the reduction in pain level after day 2 on donor and recipient site. Also, the wound healing was achieved after 14 days in all cases in donor site.
Conclusion: According to high surface absorbance, better incision, coagulation and application on both soft and hard tissues, Er;Cr:YSGG laser can be safe, minimally invasive manner and useful for all steps of the free gingival graft procedure.
