Wound healing after surgical gingivectomy occurs by secondary intention [To the best of our knowledge, no study to date has examined the effect of PBMT in combination with pure HA gel on wound healing after gingivectomy. The latter was used in the current study as recently, there has been a surge in the use of HA for cosmetic and medical reasons. In 2022, a systemic review by Rodríguez-Aranda et al. [The effect of HA on wound healing can be explained based on its properties that acts to promote soft tissue healing. One of the main known properties of HA that it has an.anti‑inflammatory effect [Our findings regarding wound healing assessment by Landry Healing Index showed that application of HA and PBMT in the test group positively promoted wound healing following surgical gingivectomy procedure (Fig. 
Wound healing after surgical gingivectomy in the two study groupsFurthermore, in accordance to our findings Turgut Çankaya et al. [In the current study, the addition of pure 2% HA gel after PBMT exhibits a positive impact on wound healing acceleration as shown in Table Uslu and Akgül [Contradictory to our results, Masse et al. [Small sample size and lack of histological evaluation of wound healing can be considered as limitations of the study. Within the limitations of the present study, PBM and 2% HA applications after surgical gingivectomy improved the quality of life of the patients. Further clinical trials with larger populations are recommended to assess the synergistic effect of PBM and HA application on wound healing in different periodontal surgical procedures. Moreover, histological assessment of soft tissue healing is also recommended.
