High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to provide better results compared with conventional treatments, a significant variation exists in the applied laser parameters such as different wavelengths and energy densities of laser. The objective of this study was to collect preliminary information about the type and parameters of surgical lasers and how to use them technically based on the available literature on this topic</span></span><span style="font-size:9.0pt"><span style="font-family:" verdana="">. </span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Materials and Methods:</span></span></span></b> <span lang="EN" style="font-size:9.0pt"><span style="font-family:" verdana="">After initial screening of 152 potentially relevant articles identified through an electronic search, 44 articles were selected based on the eligibility criteria by three independent reviewers.
