Abstract

Introduction: This study aimed to investigate the efficacy of a 980-nanometer diode laser. Application for the Free Gingival Graft (FGG) treatment and assess the Adjunctive Photobiomodulation Therapy (PBMT) effects on accelerating wound healing, postoperative pain relief, and inflammation reduction.
Materials and methods: The FGGs method was applied to five cases involving mucogingival issues. First, graft margins were outlined on the palate using a tin foil template and the recipient bed was prepared, and FGG was obtained from the palatal area. After final graft adaptation, suturing was done, the recipient site was irradiated by the low-level 980nm diode laser with the following settings, 0.2W, 5.2J/cm², 10 seconds, and Continuous Wave (CW) mode in the same session and two weeks later in the follow- up session.
Result: Results were assessed after two weeks and six months following the operation, and a satisfactory tissue healing was seen in each participant.
Conclusion: This case series demonstrated that PBMT is a safe, minimally invasive, and helpful method for improving FGG survival in the recipient sites. Consequently, it can cause a significant reduction in the duration of the healing period and post-surgical complications such as pain and inflammation in the recipient site.
