INTERESTING FACTS FROM THE WORLD OF DENTISTRY.
1. John Lennon's tooth.The legendary musician's tooth was sold at auction in 2011 for $30,000.
A photo. John Lennon.
To date, Lennon's molar is considered the most expensive tooth in history. For a long time, the tooth of Isaac Newton kept the palm - at one time it cost about $ 4,000 in terms of modern money. However, already in the 21st century, world auction houses were able to sell the teeth of Napoleon, Elvis Presley, and Winston Churchill's dental prosthesis at a very high price.
As for John Lennon, the auction organizers initially expected to raise about $10,000, but the total amount of the sale exceeded all expectations and amounted to $32,000. It is noteworthy that the artifact went to the new owner not in the at its best- he is literally eaten away by caries. At one time, the legendary performer realized that he was unlikely to be able to cure a bad tooth, so he pulled it out on his own, and then gave it to his maid as a souvenir for her daughter, who was a devoted fan of The Beatles. Subsequently, John Lennon's tooth wandered from one owner to another until it was bought by Canadian dentist Michael Zook for the above amount. It was he who at one time acquired Elvis Presley's tooth in a similar way, and in general he collected quite large collection, including the teeth of many exotic animals.
As Michael himself stated, when he found out that this lot would be at auction, the money no longer mattered to him. But much more interesting is not even how he decided to spend such a sum, but the purpose for which the Canadian acquired the tooth of the great musician. It turns out that Michael Zuk seriously expects that when science advances, he will be able to copy Lennon's DNA with the help of Lennon's molar and then clone John.
Indeed, human quirks know no bounds!

4. Teeth Love Day.
China recently hosted an annual celebration dedicated to the nation's dental health.
China is not only the birthplace of the greatest scientific discoveries and philosophical teachings. It also hosts one of the most unusual and useful holidays on the planet. Every year on September 20, millions of Chinese celebrate Love Your Teeth Day. Moreover, the holiday has the status of a national one - at one time it was initiated by the government itself.
Relative to the whole of Chinese history, this holiday is very young - it was first celebrated on September 20, 1989. Then only a few million inhabitants of the Celestial Empire took part in it. However, a few years later it was actively celebrated by more than 600 million Chinese. It is interesting that “Love Teeth Day” is held under a new motto every year. The correct technique of using a toothbrush, a balanced diet is the key to oral health, the role of a beautiful smile - these and other topics have become central over the years. In addition to the usual folk festivals and demonstrations of banners, there are specific benefits from the holiday. It is on these days that many open lectures take place, and some public and private clinics conduct free consultations on the dental health of the population.
The urgency of such a step on the part of the government is very high. Although many Chinese tend to lead healthy lifestyle of life, among the poor people living in the province, diseases of the teeth and gums are very common. This is especially true for the elderly population. Almost 90% of people of retirement age in China have caries, and 7% of this number have no remaining teeth at all.
5. Japanese dentists have found the reason for the fear of patients.
An unusual experiment was conducted by scientists from the Japan Dental Association. Doctors invited 34 people with various dental diseases, aged 19 to 49 years.
None of the patients were offered free treatment, they were asked to fill out questionnaires with simple questions. Such as: is there fear when they hear a drill, and do they have inner excitement during treatment.
Based on the completed questionnaires, all patients were divided into 2 groups of fear: slight fear and panic. After that, each volunteer was placed in an MRI machine and asked to relax. While scanning a person around him, scientists moved dental instruments, turning the drill on and off, and monitored the condition of the instruments and the patient.
As a result, they received an exhaustive result - a proof. At the dentist's appointment, the patient is not afraid of the drill itself or the process of drilling the tooth, but is afraid of the very sound that the drill makes. Only in the group with panic fear from the sounds of a fast-moving instrument, areas in the cerebral cortex responsible for emotions and behavioral functions were activated.
The solution to reduce patients' fear is to reduce the noise level emitted by dental drills. In addition, scientists recommended that dentists conduct soothing conversations with patients.
6. American designers have created an Internet toothbrush.
On January 5, 2014, American "kulibins" showed the public the first toothbrush that can connect to the Internet, transmitting data on the condition of the teeth and the quality of their cleaning. At the international exhibition on January 5, 2014ConsumerElectronics showUS inventors have discovered a new product "Smart" brush. Initially, the project was French.
This miracle of technology has specific sensors that “understand” the quality of brushing teeth from tartar and plaque. At the end of cleaning, the collected information is sent via Bluetooth to the owner's smartphone, on which a special application is installed. Based on these data, a person will be able to analyze his work on oral hygiene and identify those places that he “didn’t clean” or “didn’t get”.
According to statements, the cost of this brush, depending on the modification, will be in the range of 100 to 200 US dollars. The designers only needed to finish the tool a little to make it more convenient and comfortable to use.
7. Russia has invented a golden toothbrush!
Russia has invented a golden toothbrush. Patent for a self-disinfecting toothbrush, which also has medicinal properties, was recently received by a Russian inventor from Rospatent. Regular use of such a brush protects not only from various diseases of the teeth and oral cavity, but also from SARS, influenza and many other diseases, strengthening the immune system.
According to the inventor of the brush Evgeny Rodimin, healing properties the miracle brush is given noble metals - gold and silver, or rather, silver ions, which are released when it is immersed in water. At the heart of the invention is a discovery that is still almost unknown to the scientific community. The fact is that silver, which is constantly in contact with gold, after immersion in water, releases ions much more actively than under normal conditions.
Although in Russia no one still makes brushes that emit silver ions, abroad the properties of ions to disinfect water and strengthen the immune system have been used by toothbrush manufacturers for more than a year. The novelty of the Russian invention is that, thanks to gold plating, the brush emits 600 times (!) More silver ions than "foreign" counterparts.
Accordingly, both the healing effect and the speed of self-disinfection of the Russian brush exceed the best foreign indicators. It is also important that if the brush is ever introduced into production, it will be much cheaper than less efficient imported ones. At present, the author has somewhat modernized his invention and will soon receive a second patent.

Much more important is the ability to control your lips and correctly change the position of the tongue, because, in fact, the sound from clicking on any of the teeth will be approximately the same, and a meaningful melody arises due to the acoustic properties of the oral cavity. With the right approach, the musician can make sounds reminiscent of playing the xylophone.

In everyday life, the words "dentist" and "dentist" are often used interchangeably in the sense medical worker who treats teeth. Are these words really synonymous or are there differences between them? How do specialists differ, what specializations do health workers have in dentistry?
Dentist vs Dentist: What's the Main Difference?
A dentist is a doctor who received a higher medical education at a university in the specialty "Dentistry". After completing general education, he chooses a specialization - therapeutic, surgical treatment, prosthetics.
The word "dentist" is rarely used in our country, most often this is the name of foreign specialists involved in the treatment of diseases of the oral cavity. In the Russian-speaking environment, it is synonymous with the concept of "dentist".
Who is this? These are specialists with a secondary special education who have graduated Medical College and also have the right to treat teeth. In addition, they include dental technicians who make prostheses. Thus, the dentist and the dentist are not exactly synonymous, but in some situations the words can be replaced.
What does a "dentist" do?
The dentist has the right to perform a limited list of tasks. He treats simple diseases, but if the solution of the problem with which the patient applied is not within his competence, the specialist is obliged to redirect the patient to a doctor of the highest category with the appropriate specialization.
Professional tasks:
- initial examination of the oral cavity, diagnosis;
- filling of shallow caries without complications;
- treatment of gum disease - stomatitis, gingivitis;
