More and more doctors choose and recommend ultrasonic toothbrushes for their patients. How do they work, how do they differ from regular electric and sonic brushes, what is their therapeutic effect and will they become the “brushes of the future”?
There is a theme – let’s open our mouths..
We could not leave the topic of ultrasonic toothbrushes without attention. This device first appeared in the nineties of last century on sale since 1995 , it has gained popularity in recent years: yet any technical innovation needs both the “promotion” and the recognition of its effectiveness by professionals and ordinary users.
Electric toothbrush, sound or ultrasonic?
The main confusion for consumers is the difference between simple electric toothbrushes, sonic brushes and ultrasonic. While preparing this material we faced with a total lack of understanding of the issue by consultants of many online stores, calling sonic brushes as ultrasonic, ultrasonic electric and openly lumping these devices absolutely different by device and principle of action into one pile.
In recent years, electric toothbrushes evolved in sports style – faster, higher, stronger – and increased not only the number of functions and options used in the devices eg, gum pressure sensor, timer, head replacement indicator , but also the number of movements of the head itself or two heads performing the rotation in different directions .
Minus of rotary brush head – poor hygiene: there is inevitable clogging of residual paste and dirt under the moving part, which leads to unpleasant smell of the cleaning heads.
Some manufacturers Oral-B, Panasonic, Philips, etc. have improved their models: now the brush head does not rotate – it fits tightly to the base, and the movement performs itself bristles, and these movements have become “volumetric”: the rotation added pulsation.
That’s how most of the so-called “sonic” electric toothbrushes are set up, but their main difference is that they built in a frequency generator that generates a sound wave. These brushes often use linear motors, which increases their reliability and durability.
Each bundle of bristles on these appliances performs 9,000 to 18,000. up to 31-34 thousand. The more “advanced” models at a rate of brush strokes per minute for best cleaning results.
The high frequency sound vibrations help “whip” the toothpaste and saliva and this cleansing, oxygen-rich substance is able to penetrate into the interdental spaces and there fight the plaque which loosens under the influence of the sound vibrations and is easier to remove.
The big advantages of sonic brushes for the user are their gentle, gentle brushing and high hygiene compared to conventional electric brushes.
The ultrasonic toothbrush works on teeth and gums by ultrasound, which is invisible to the human ear.
The honor of inventing this new means of hygiene is owned by American Dr. Robert Bock, and for quite a long time, ultrasonic brushes were sold exclusively under the Ultrasonex brand name and had no analogues.
Do you know what’s in your mouth??
The ultrasonic toothbrush uses a dual motor type USM Ultra Sonic Motor – a motor in which the working element is a piezoelectric ceramic.
Because of this it is able to convert electrical energy into mechanical energy with a very high efficiency of over 90%, that is, the power consumption of such brushes is uniquely low.
There is a piezoelectric plate under the brush head which converts the electrical energy into mechanical vibrations at a frequency of 1.6-1.7 MHz.
This frequency is not selected by chance: its effect together with low electric power transmitted to the piezoceramics up to 0.2 W creates vibrations in an elastic medium like water in the mouth at a distance of no more than 4 mm from the bristles.
Ultrasonic toothbrushes use ultrasound alone or in combination with audible vibrations. The brush is equipped with a microprocessor that counts intervals of 30 seconds and allows you to determine the time of exposure, after which the brush should be moved to another area of the mouth.
How does ultrasound clean your teeth??
During the use of an ultrasonic brush in the mouth feels a pleasant warmth: tissues are heated by about 1 ° C, which makes the biochemical processes in the mouth more intense. The endogenous heat generated in the tissues dilates the blood vessels and therefore improves blood microcirculation.
The result is an increase in the activity of several enzymes, the intensity of tissue redox processes. Tissues produce biologically active substances: heparin, histamine, serotonin, etc.
Ultrasound activates the absorption of beneficial substances and trace elements contained in toothpastes and oral balms. With its unparalleled micro-oscillation frequency of 102 million vibrations per minute, this toothbrush can remove all kinds of plaque, from food plaque to tobacco plaque.
At the right dosage ultrasound has analgesic, resolving and antispasmodic effect.
What Dentists Brush Your Teeth with?
Our inquisitive compatriots have arranged the real intellectual and not so much disputes on forums about ultrasonic toothbrushes. Forum members were baffled by two questions: how to check in everyday conditions the presence of ultrasound, indistinguishable by the human ear, and whether it is harmful.
To arrange the test, citizens offered: to dip the brush into mineral water supposedly should increase gas emission into a container with water and lime scale the latter should crumble to follow the behavior of cats and mosquitoes in the area of the device they should get nervous to put the brush to a ferrite antenna of a Chinese radio receiver..
On the harm of ultrasound brushes were also expressed many unexpected and diametrically opposed: that it destroys cells, it can break the teeth, but for some reason does not cope with dental calculus, or does not work at all.
This variety of “smart thoughts” is commented upon by our professional advisor, “The physical nature of all sounds is the same. The term “ultrasound” means “inaudible sound”. Despite the fact that we do not hear it, it is constantly present with us. Animals use ultrasound to navigate and communicate.
Even the wings of small insects emit ultrasound as they fly. Claims of harm from exposure to low levels of ultrasound are unsubstantiated. As the medieval scientist Paracelsus said, “any substance can be considered a poison, the only difference is the amount”.
In an ultrasonic toothbrush selected safe level of ultrasound, which passed the certification test. In MSanPin 001-96 set the permissible level of sound pressure 100 dB, the ultrasonic brush produces no more than 37 dB. Many people here confuse ultrasonic mechanical vibrations with often harmful electromagnetic radiation – these are different things.
Toothbrush ultrasound level is not designed to break up calculus – either professional devices with strong ultrasound or abrasive devices can do it. But the ultrasonic brush provides a higher level of hygiene – this can be felt after the first use”.
