Ultrasound Scanner
(2596 Views)
In the process of plaque removal, ultrasound scanners are being increasingly used. In ultrasound scanners the working ends are moved within a frequency range that matches the ultrasound waves from about 35 kHz to gHz. The movement of the working ends of ultrasound scanners is different from the working ends of well-known drills as they swing rather than rotate. While using an ultrasound scanner, the tooth has to be thoroughly cooled with water as the ultrasound waves produce a lot of heat, which might lead to tooth nerve damage. Another risk of using ultrasound scanner is that it leads to the loss of teeth substance. Often, dentists use ultrasound scanners to remove the discoloration caused by excessive tea, coffee or nicotine. This however, leads to the loss of tooth surface and a better way of removing discoloration is bleaching. Nevertheless, ultrasound scanners are commonly used for the removal of plaque. Calculus is removed by the ultrasonic metallic units and after the plaque removal, the enamel is polished. In order to stop the plaque from coming back, most ultrasonic units roughen the surface of the tooth during tooth removal. As such, it has been proven that an ultrasound scanner should be used only for plaque removal and discoloration of teeth should be treated with bleaching.
