Er,Cr YSGG Provides An Efficient Laser Crystal
Product Description
Due to the variety of treatment options, dentine hypersensitivity (DH) is a painful disease and a clinical challenge. As a potential solution, high-intensity lasers have been researched. This clinical trial was designed to examine the effects of Er:YAG and Er,Cr:YSGG lasers on DH. It was randomized, controlled, and double-blind. The 28 participants in the study group all satisfied the requirements for inclusion. Sensitivity was measured using a visual analogue scale before therapy as a baseline, immediately before and after treatment, as well as one week and one month following treatment.
No variations between the pretreatment sensitivities were seen for either the air or probe stimulation. The evaporative stimulation decreased the pain level right after treatment, but the levels stayed consistent after that. The least amount of discomfort was seen after Er:YAG laser irradiation. Group 4 saw the greatest pain reduction with the mechanical stimulation right away, but by the conclusion of the research, pain levels had risen. During the 4 weeks of clinical follow-up, groups 1, 2, and 3 shown a decrease in pain that was substantially different from that of group 4's.The Er:YAG and Er,Cr:YSGG lasers are effective for treating DH, although none of the laser treatments examined were able to totally eliminate pain, based on the findings and within the parameters of this study.
YSGG (yttrium yttrium gallium garnet) doped with chromium and uranium provides an efficient laser crystal for light generation at 2.8 microns in the important water absorption band.
Advantages of Er,Cr: YSGG
1.Lowest Threshold and Highest Slope Efficiency (1.2)
2.Flash lamp can be pumped by Cr band, or diode can be pumped by Er band
3.Available in continuous, free-running or Q-switched operation
4.Inherent crystalline disorder increases pump line width and scalability
