TY - JOUR AU - AB - Laser have various periodontal applications including calculus removal (erbium yttrium scandium gallium garnet and erbium yttrium aluminum garnet lasers), decontamination of root and implant surfaces and bio stimulation, incision and ablation, osseous surgery, excision of the soft tissue, and bacterial reduction. This chapter analyzes the most important occasions in which lasers are used in implant and periodontal field practices. There is a strong evidence that laser is used for surgi- cal and nonsurgical periodontal therapies including root bio modification, bacterial decline and decontamination of infected implant surface (in peri-implantitis), and removal of the pocket epithelium. This chapter also highlights the most com- mon disadvantages as well as the advantages of using lasers in periodontal therapy. Waterlase® and Periowave™ systems are recent devices that have further revolu- tionized the laser technology for its favorable clinical applications; however, the pro- cedural cost with the laser device constitutes an obstacle for its routine application. Keywords: erbium yttrium scandium gallium garnet laser, erbium yttrium aluminum garnet laser, periodontal therapy, peri-implantitis, bacterial reduction 1. Introduction LASER, an abbreviation of light amplification by stimulated emission of radia- tion, was first established by Maiman in 1960 [1], a scientist of the Hughes Aircraft Company.
