Ultrasonic techniques. Overcoming the hesitation to use the devices all the time. When you think back to the first generation of ultrasonic scalers, you realize how far dentistry has progressed. Many different types, designs, and uses for scalers are available today. The original ultrasonic scaler, though, was designed to remove decay.
Class 1M lasers produce large-diameter beams, or beams that are divergent. The MPE for a Class 1M laser cannot normally be exceeded unless focusing or imaging optics are used to narrow down the beam. If the beam is refocused, the hazard of Class 1M lasers may be increased and the product class may be changed. Class 2. A Class 2 laser emits in the visible region (400-700nm).
