【 摘 要 】

Introduction: the Er,Cr:YSGG laser has a suitable wavelength for the ablation of both hard and softtissues of the periodontium and can be considered as a potential tool in periodontal surgeries. Thecurrent study aimed at evaluating the application of this laser versus conventional instruments inperiodontal pocket reduction flap surgery.Methods: Eight patients (16 dental arches) requiring periodontal surgery were included (Trialregistration number: IRCT201711129014N199). Using a split-mouth study design, two posteriorsextants of a dental arch were randomly allocated into either a test group, open flap debridementperiodontal 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, 2-3.5W output powers and Air-20%, Water-60-80% were applied and adjusted individually for eachstep of the flap surgery procedure. Baseline, 1 and 3-month measurements of plaque index (PI),Gingival Index (GI), gingival recession (GR), probing depth (PD) and clinical attachment level (CAL)were recorded for comparisons. Data were analyzed by a linear model for correlated data using thegeneralized estimating equations (GEE) method and the least significant difference (LSD).Results: In both treatment groups, reductions in PI and GI were observed in the 3-month follow-upperiod. These indices were significantly lower in the laser-treated sides compared to the conventionalgroup (P<0.05). The Mean PD and CAL were lower at 1 month and 3 months compared to thebaseline in both groups (P<0.05). However, these parameters were not statistically different inthe treatment groups during these follow-up timelines. An increase in GR was observed from thebaseline 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 flapsurgery resulted in similar treatment outcomes to the conventional method and may be consideredas a safe and effective treatment modality.
