FREQUENTLY ASKED QUESTIONS
What is Ultrasonics/Ultrasound: Sound waves vibrating at frequencies greater than 20,000 cycles per second, i.e., beyond the range of human hearing. Ultrasonic is an adjective, and ultrasound is a verb.
How is ultrasound produced: Ultrasound is produced, commonly, by a transducer. The transducer converts electrical energy into vibrating ultrasonic waves. When you pass ultrasonic waves through a conducting medium e.g. solution - cavitation occurs. These vibrations cause large numbers of invisible bubbles to explode with great force on the surfaces of the objects. This force destroys the cell walls of bacteria and removes film from surfaces e.g. stains from teeth
Areas where Ultrasound is used: In medicine ultrasonic devices are used to examine internal organs without surgery and are safer to genetic material than X rays. The waves with which the body is irradiated are reflected and refracted; these are recorded by a sonograph for use in diagnosis.
In the aeronautical industry machine parts, ball bearings objects can be cleaned ultrasonically. Small delicate surgical instruments are also cleaned with ultrasonics prior to sterilisation.
Is ultrasound used in ultrasonic toothbrushes dangerous?
No, all ultrasound products developed by EMAG AG are absolutely safe. Ultrasound has been used in medicine for various purposes for decades. It is harmless. The ultrasound in Emmi-dent uses only 0.2 watts. Medical research has proven that ultrasound up to 50 watts is not harmful to the human body. Teeth cleaning and oral hygiene with ultrasound can be used by anyone, whether young or old, or a person with a pace maker or using other medical technological aids.
Will the ultrasound from an Ultrasonic toothbrush intefere with other equipment, such as a pacemaker?
As ultrasound is a movement of air caused by very high frequency noise, not an electrical charge, there is no reason to expect ultrasound will interfere with other equipment. If you are concerned, you should check with your doctor or the manufacturer of your device.
What is the difference between a sonic and an ultrasonic toothbrush?
Sonic toothbrushes rely on mechanical action to abrade the debris from your teeth. Typical “sonic” toothbrushes have bristle movements of 15 to 40 thousand movements per minute. Ultrasonics operate at 96 million vibrations per minute i.e. 4,800 times more powerful.
Ultrasound brushes use high frequency ultrasound to detach bacteria. This means the ultrasound does the hard work, with the brush head only required to gently sweep the debris away.
