The cavitron is an ultrasonic scaler. Power scalers do a more thorough job in less time. This results in significantly decreased scaling time and healthier, cleaner teeth and gums. Hand scalers require repetitive scraping movements and are restricted to adaptation of only one or two sides of the instrument. In comparison, all four sides of a power scaler can be adapted, because the device moves in an elliptical motion. This comes in handy when removing stain and deposits from behind and between the teeth. Ultrasonic scalers are more effective in removing stain as well. The ultrasonic vibration helps control oral bacteria by breaking down the cell wall of the bacteria. The water used to cool the cavitron then helps to rinse away bacteria, stain and debris.
