There is an opinion that electric toothbrushes cleanse the teeth and oral cavity better than more common manual. We decided to check if this is so.
On the Internet you can find many articles With a comparison of electrical and hand dentitions, and usually their authors are inclined in favor of the former. Media write about this (for example, "Gazeta.ru" And "Express Gazeta") And specialized Dental Portals. Resourcesdedicated to technology and new technologies, also Consult Readers choose electric toothbrushes due to their greater effectiveness. Discuss This question and users social networks.
Electric toothbrushes were Invented Back in 1954, but widespread are relatively recently. These devices Differ By the type of movement (vibrational and rotational-spatting) and in speed (sound, that is, rotating at a speed that creates the sound captured by the human ear, and faster ultrasonic ones).
The cost of electric brushes is much higher than usual: on popular marketplaces in Russia in July 2023 prices manual brushes start from 19 rubles, while electric Models Popular brands cost from 990 rubles (in addition, periodically for them it is necessary buy Replaceable nozzles). Therefore, before switching from a manual brush to an electric one, many have a question whether she is worth her money.
Researchers of the authoritative Medical Kokrain Library in 2014 conducted review The scientific literature that existed at that time about the effectiveness of electrical toothbrushes (without specifying their type) compared to manual and came to the conclusion that in the short term, the former and really better cope with the dentist and inflammation of the gums. At the same time, the long -term effect of such brushes on the health of the oral cavity remained unclear.
In 2019, German scientists published generalized data 11-year observation of the health of the oral cavity 2819 people. They concluded that those who used electric toothbrushes developed (or progressed more slowly) periodontal disease and caries, cases of teeth loss also occurred less often. Scientists note that, apparently, in the long run, the use of such brushes is preferable for the health of the oral cavity. In this study, as in the previous one, the type of electric shock was not taken into account.
Dentists Markthat the key moment in the use of dental brushes is the right technique. To brush your teeth at least two minutes, making circular movements, holding the brush at the right angle and without pressing it on it. In many modern ones models All this is controlled automatically: there is an integrated timer that allows you to monitor the cleaning time, the brush head makes the necessary circular movements, and it would be much faster than it would be possible to do it manually, in some devices there is even a sensor that gives a signal if the user pressed the brush to the teeth too much and thereby harm the enamel or tar.
Such ease of use is especially important for children and adolescents who may not know about the right technique or not attach the importance of how exactly they brush their teeth. In 2018, German scientists conducted experiment: They took 60 teenagers aged 13 to 17 years and divided them into two groups, the first of which used a conventional brush, and the second-rotational-cellular electric. During the experiment, the process of brushing the teeth took place under the supervision of specialists, and it turned out that adolescents using electric brushes brushed their teeth longer. Two weeks later, the dentists examined the subject of the subjects of the subjects and found out that in the group using the electric shock, the number of dentition was below more than 30%.
In 2019, a group of scientists from different countries I studied The effectiveness of electric toothbrushes of a rotational-celly type when brushing teeth in children. The study was attended by 41 children in two age categories (three to six and seven to nine years); The younger group was brushed by parents, the eldest did it on their own under the supervision of adults. The experiment lasted about a month and took place in four stages: each child used both types of brushes twice for the study; The order in which they were applied was defined randomly. As a result, it turned out that electric brushes were 32.3% more efficiently removed to the tooth coat in children in the younger group and by 51.9% in the eldest.
But the studies conducted among the elderly subjects Brazilian And Norwegian Scientists have not revealed a statistically significant difference in the health of the teeth and the amount of dental plaque after cleaning with an ordinary toothbrush and electric.
According to data research, carried out back in 1996 by German dentists, electric toothbrushes of various types are more convenient for people wearing braces. During the experiment, 38 patients undergoing treatment at an orthodontist, for four weeks, different types of electric toothbrushes were used, and it turned out that their use allowed to maintain oral hygiene without attracting additional tools (interdental brush and dental thread) necessary for manual cleaning.
At the same time, experts Markthat the use of an electric brush for all its advantages is not a necessary condition for the health of the teeth. Manual brush too Can It is quite effective to maintain the cleanliness of the oral cavity, if you use it correctly. Much more important The regularity of teeth brushes than the type of brush.
Thus, authoritative clinical studies confirm that electrical toothbrushes of various types compared to manual are more effectively removed toothache in children and adults and help preserve the health of the teeth longer. The results of studies conducted on the elderly did not show a statistically significant difference between conventional brushes and electric ones. Nevertheless, dentists note that if you use a manual brush correctly, it can also quite effectively maintain oral hygiene, it is not necessary to buy an expensive electric shock for this. At the same time, with the help of such devices, taking care of the cleanliness of teeth is really easier due to a variety of sensors and timer, which help to control the correctness of the technique and the necessary duration of the procedure.
