Objective: The aim of this study was to compare the effects of laser photobiomodulation (PBM) and topical ozone therapy on the reepithelialization of palatal donor site wounds through clinical assessment and computer-aided image analysis and to assess the patient morbidity following free gingival graft (FGG) surgeries. Material and methods: Thirty-six patients requiring FGG were randomly allocated into three groups: laser group (n=12), ozone group (n=12), and control group (n=12). Epithelialization was evaluated by applying 3% hydrogen peroxide (H2O2) to the wound area and also measured by using digital image analysis (ImageJ). Bland-Altman plots were used for assessing agreement between H2O2 and ImageJ measurements. Parameters in relation to patient morbidity were assessed by using visual analog scale (VAS) on the first 3, 7, 14, and 30 days postoperatively. Results: At day 14, statistically significant smaller wounds were observed with digital image analysis in the ozone group as compared with the control group (p=0.034). However, intergroup comparison of the remaining wound area evaluated by the clinician using the H2O2 method did not reveal any significant differences (p>0.05). Nonetheless, according to Bland-Altman analysis, the lower and upper limits showed a moderate agreement between the two measurement methods. The mean VAS sores exhibiting postoperative discomfort was observed to be significantly higher in the control group compared with the laser group (p=0.002) and ozone group (p<0.001) at day 7. Conclusions: Adjunctive ozone therapy could have a significantly beneficial effect on the acceleration of palatal wound healing following FGG procedures. Both PBM and ozone treatment modalities reduced postoperative discomfort as compared with spontaneous healing.
