**4. Advantages of using lasers in the periodontal therapy**

Less pain. Less need for anesthetics (an advantage for medically compromised patients). No risk of bacteremia. Excellent wound healing. No scar tissue formation. Bleeding control (dependent on the wavelength and power settings). Usually no need for sutures. Use of fewer instruments and materials and no need for autoclaving (economic advantages). Ability to remove both hard and soft tissues. Lasers can be used in combination with scalpels (however, the laser is a tool and not a panacea) [67].
