Introduction: The Er,Cr: YSGG laser has a suitable wavelength for the ablation of both hard and soft tissues of the periodontium and can be considered a potential tool in periodontal surgeries. The current study aimed at evaluating the application of this laser versus conventional instruments in periodontal pocket reduction flap surgery.Methods: Eight patients requiring periodontal surgery were included. Using a split-mouth study design, two posterior sextants of a dental arch were randomly allocated into either a test group, open flap debridement periodontal surgery using the Er,Cr:YSGG laser, or a control group using the conventional method. Laser parameter settings of a 2780 nm wavelength, H mode (60 µs pulse duration), 25-50 Hz, 2-3.5 W output powers, and Air-20%, Water-60-80% were applied and adjusted individually for each step of the flap surgery procedure. Baseline, 1-3 month measurements of plaque index, Gingival Index, gingival recession, probing depth, and clinical attachment level were recorded for comparisons. Data were analyzed by a linear model for correlated data using the generalized estimating equations method and the least significant difference.Results: In both treatment groups, reductions in PI and GI were observed in the 3-month follow-up period. These indices were significantly lower in the laser-treated sides compared to the conventional group (P<0.05). The Mean PD and CAL were lower at 1 month and 3 months compared to the baseline in both groups (P<0.05). However, these parameters were not statistically different in the treatment groups during these follow-up timelines. An increase in GR was observed from the baseline to 1 month and 3 months with less recession in the laser-treated sides (P=0.016).Conclusion: Based on the results of the present study, the Er,Cr:YSGG laser-assisted periodontal flap surgery resulted in similar treatment outcomes to the conventional method and may be considered a safe and effective treatment modality DOI:10.34172/jlms.2022.04.
