Experimental: Test Group
Combined laser therapy: An Er:YAG laser (160 mj/pulse, 10 Hz) (AT Fidelis Fotona, Ljubljana, Slovenia) with water irrigation was first used to remove subgingival calculus and infected cementum.The Er:YAG laser beam was delivered into the periodontal pockets using a chisel-shaped quartz tip in contact mode under water irrigation, from a coronal to an apical direction with the tip inclined at 10o to 15o to the root surfaces. After Er:YAG laser application, Nd:YAG laser treatment (AT Fidelis Fotona, Ljubljana, Slovenia) was performed at an energy level of 100 mJ/pulse, and 20 Hz for removing pocket epithelium and detoxiﬁcation purpose. Irradiation was accomplished with a 320 μm fiber optic delivery system. The fiber was inserted into the periodontal pocket base in parallel alignment with the root surface, and the fiber was slowly moved from apical to coronal in a sweeping motion during the laser light emission.
