Comparison of Nd:YAG, Er,Cr:YSGG and Diode Lasers in Nonsurgical Periodontal Treatment

Mariya Miteva ^[10]

Abstract: Purpose: The aim of the study was to evaluate and compare the clinical efficacy of Nd: YAG, Er, Cr: YSGG and Diode lasers as an additional tool for non-surgical periodontal therapy. Methods: The study included 60 male and female patients with chronic generalized periodontitis who were divided into the following groups: 1-SRP + Nd: YAG, 2-SRP + Er, Cr: YSGG, 3-SRP + Diode, 4-SRP (control group). A hygienic phase of periodontal treatment was performed for all patients. Probing pocket depth, gingival margin and clinical attachment level were registered for the patient prior to the treatment initiation as well as at 1, 5 and 3 months after it. In groups 1, 2 and 3 the periodontal pockets were treated with the corresponding laser after SRP, whereas the control group was not treated with a laser as an additional tool. Results: At three months after treatment, there was no statistically significant difference in the measured clinical parameters between the SRP group and the groups for which high-energy lasers had been used. Conclusion: The results of the study and their statistical processing showed similar results between all study groups and it was proved that the application of SRP + high-energy laser did not lead to better clinical results. The experimental-statistical study requires to be traced for longer period of time in order to adequately evaluate the presence and frequency of recurrences after the administered treatment methods.
