INTERESTING FACTS FROM THE WORLD OF DENTISTRY.

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 new owner did not get the artifact in the best possible condition – it was 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 a rather 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!

2. Stars with a gap between the teeth.

Why don't stars with a gap between their teeth want to get rid of it once and for all?

Stars with a gap between their teeth have been popular at all times, they have never been ashamed of their lack and even managed to turn it into a fashion trend. We present to your attention the most famous celebrities with a gap between their front teeth, who are immensely proud of them.

A photo. Actress Brigitte Bardot.

The legislator of this strange fashion is the recognized sex symbol of the 50s, the famous actress Brigitte Bardot, who, by the way, now lives in a villa in Saint-Tropez, along with several hundred animals. This seductive woman conquered everyone not only with her rounded shapes and revealing outfits, but also with a sensual smile, the invariable attribute of which was a small gap between her front teeth.

A photo. Actress Vanessa Paradis.

Vanessa Paradis is another French woman with a gap between her teeth, who drove hundreds of men crazy. Unlike most of her colleagues, she never thought about orthodontic treatment and considered her smile a gift from God. The actress has repeatedly said that the diastema - the scientific name for the gap between the teeth - makes it special and brings happiness, and also that it is convenient to drink through a straw with its help.

A photo. Elton John.

Sir Elton John's army of fans has become even larger after he stated that he was not going to change anything in his appearance, including removing the diastema.

A photo. Madonna.

The most famous American diastema is Madonna. Despite the fact that the singer's teeth were subjected to aesthetic correction more than once, she flatly refused to remove the diastema. Moreover, the star made a real scandal when the publishers of a popular magazine "smeared" her gap in one of the photos.

A photo. Willem Dafoe.

If we were to present an award for the most outstanding gap between the teeth, Willem Dafoe would certainly receive it. Firstly, he has more than one - the actor has rather rare teeth, which gives his already unusual and somewhat frightening image a special piquancy. And secondly, the actor is so proud of them that he even starred in a short film known in Russia as "The Slit". The author of this unusual picture was our young director Grigory Dobrygin. The film is entirely devoted to Defoe's teeth, or rather the gaps between them.

3. Monuments dedicated to dentists.

The owner of one of the clinics in the Ukrainian city of Vinnitsa built a sculpture of a dentist in the courtyard of his institution. The iron doctor has a toothbrush in his hands, and dental instruments are located in his chest pocket. Next to the sculpture is a chair and an ancient drill that was used for dental treatment many decades ago. Sculpture in Vinnitsa has become very famous, attracting many tourists and citizens of the city.

A monument to a children's dentist was erected in Tyumen. It is located at the children's department of the dental clinic No. 3. The sculpture is an image of a slender, long-haired young man with a broad smile, who holds a huge tooth in one hand, and behind his back are tongs of no smaller size. Despite the grotesque depiction of the tooth extraction procedure, the children from the bronze doctor are simply delighted. Many even have a peculiar ritual - to touch the monument or rub a tooth in his hand so that the treatment is successful.

Unusual monuments - a monument to the tooth in the city of Chita.

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. Despite the fact that many Chinese people tend to lead a healthy lifestyle, among the poor people living in the provinces, 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. A patent for a self-disinfecting toothbrush, which also has healing properties, was recently received by a Russian inventor at 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, Yevgeny Rodimin, the healing properties of the miracle brush are given by 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.

8.Teeth as a musical instrument.

The story of how "tapping" melodies on the teeth became a whole musical direction.

Zubariki is the art of melodic tapping with fingers on the tops of the front teeth. This term appeared at the beginning of the 20th century on the territory of Tsarist Russia, however, the masters of "dental music" existed even earlier. Usually, the nails of four fingers of both hands are used for sound extraction, however, various techniques are common among craftsmen, so the number of fingers involved is not critical. 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 Russia, "zubariki" were constant fun in the street and criminal environment. The film "Republic of SHKID" brought her the greatest fame, where the characters were very good at musical playing on their teeth. However, fans of this style are found all over the world: there are many videos on You Tube in which people demonstrate their musical abilities in this way, and sometimes there are real nuggets among them. Be that as it may, do not rush to look for a new use for your teeth, because from a medical point of view, such an occupation is harmful to them. Constant mechanical impact often causes enamel damage and chips, so we advise you to master more familiar and safer musical instruments.

The found tooth is about 14 thousand years old. Scratches were found on it in places of accumulation of caries. Perhaps the person who tried to heal a tooth was the first dentist in the world. The treatment was carried out with the help of instruments made of hard rock. With these tools, the physician scraped off the parts affected by caries from the tooth.

Also, a hole was found in the tooth, filled with an unknown material similar to wax.

Many treatises were devoted to hygiene in India; on the recommendation of ancient doctors, teeth were cleaned with a brush made of soft tree branches; tooth powder was prepared from honey, long pepper, dry ginger, and so on.

Since time immemorial, people have been interested in questions related to their teeth: why do they deteriorate and hurt, and how to deal with this nuisance?

We dug a little into the archival data and, with the help of archaeologists, historians and journalists, selected for you the most interesting, in our opinion, facts about dentists, dentistry and everything that was somehow connected with teeth, from ancient times to our days .

So, did you know that:

The very first dentists were the ancient Etruscans. They already knew how to insert new teeth, which were cut from matching animal teeth. Dentures, made in the seventh century BC, were quite durable and quite suitable for chewing rough food.

The oldest dental drill is about 9,000 years old. It was found in the excavations of Mergar, a Pakistani burial site dating back to the Neolithic era. In addition, eleven of the ancient people buried there, during the examination, were found to have traces of dental intervention.

The healers of ancient Japan removed teeth simply with their bare hands, after loosening them with a wooden chisel and hammer.

Ancient Egypt is considered the birthplace of the first toothpaste, which was obtained from a mixture of crushed pumice, eggshells, myrrh and ashes from the burnt insides of a bull. Therefore, even five thousand years ago, young Egyptians could boast of a snow-white smile after using such a mixture for brushing their teeth.

The ancient Egyptians already knew how to fill their teeth. And their missing teeth were replaced with artificial ones, which were tied with the help of gold wire to neighboring teeth.

The ancient Greeks believed that toothache was the result of telling a lie.

In ancient Rome, urea was the main ingredient in toothpaste. The ammonia contained in it does an excellent job of cleaning the teeth from plaque.

The first animal bristle toothbrushes appeared in China as early as the fourteenth century. The toothbrush, which is familiar to us, acquired thanks to the British. In 1870 in England, for the first time, bristles were inserted into a bone handle and tied through holes in it. In 1938, the Americans invented nylon, which almost immediately began to be used to make artificial bristles for toothbrushes.

French court ladies during the time of King Louis XI tried to avoid eating solid foods, as they seriously believed that increased chewing leads to the formation of wrinkles on the face.

The famous Frenchman from Angers, Pierre Fauchard, became the first orthodontist. He, being a famous dentist during the time of Louis XV, in 1728 invented a plate for straightening teeth - a thin strip of silver or other metal, which was attached to the teeth with the help of wire and silk ligature. By the way, he was the first to cover the “spoiled” teeth with caps of gold, which were then applied to porcelain matched in color. Since that time, porcelain and metal-ceramic crowns have been leading their glorious history. This pioneer and founder of modern dentistry also invented dental pins. Fauchard could attach several more artificial teeth to the pinned teeth - these designs became the founders of modern dental bridges. And this all happened almost 300 years ago. Incredible!

The dental bur was invented in 1790 by John Greenwood. Also, being George Washington's dentist, he made four removable dentures for him, and made the first foot drill from his mother's spinning wheel.

Isaac Newton's single tooth was the most expensive tooth in human history. It was sold at auction in 1816 for 730 pounds sterling (in terms of the modern rate - about 3200 US dollars) to a nobleman, who later decorated his ring with this tooth. But, in the fall of 2011, this record was broken.

On November 5, 2011, another sensational news spread around the world - the molar tooth of the famous British rock musician, the Beatle John Lennon was sold at auction. Auctions were held in the English city of Stockport, where the auction house Omega Auctions auctioned John Lennon's yellowed tooth affected by caries. During the auction, Canadian dentist Michael Zuk bought Lennon's tooth over the phone for £19,500, or €22,600, or $31,000 in current exchange rates. This is a new record! Now the most expensive tooth in the world is John Lennon's tooth.

In the nineteenth century, a fairly inexpensive technology for making artificial teeth from ceramics was invented. Up to this point, the teeth of soldiers who died during the war were used to make prostheses. So during the civil war in the United States, England received a huge amount of scarce "material" for dentures.

George Washington, who by the time of his presidency had lost all but one of his teeth, was very attentive to the health of his horses' teeth. Every day he checked their condition and quality of cleaning, giving grooms and veterinarians a lot of trouble.

In 1867, Lucy Taylor became the first American woman to earn a dental degree. In the same year, her compatriot named Rigg carried out the first, in the history of dentistry, curettage of periodontal pockets.

In 1868 George Green, a mechanic for the S.S. White, invented the foot-operated pneumatic drill, which allowed the dentist to work with one hand, and was the prototype of modern turbine installations.

Chewing gum acquired its flavor in 1870 and was named "Black Jack", thanks to Thomas Adams - a well-known inventor and manufacturer of chewing gum at that time.

Who would have thought that a dentist would invent the electric chair. Incredible, but true. In the nineteenth century, the American Albert Southwick wanted to use a dental chair with an electric current applied to it to anesthetize the teeth. But history decreed otherwise. At that time, there was very fierce competition for the creation of new AC-based power supply systems. At the same time, experiments with electric current (including the killing of animals) were carried out by Thomas Edison and his employees Harold Brown and Fred Peterson. In 1890, in New York City, the electric chair accepted its first victim, a certain William Kemmler, and has since become known as "Thomas Edison's Electric Chair".

Mao Zedong never took a bath, washed his hair or brushed his teeth. He, like millions of Chinese who imitated him at that time, loved to chew tea leaves and rinsed his mouth with tea, thus getting rid of plaque. "Does a tiger brush its teeth?" - liked to repeat Mao Zedong. This policy has led to the fact that dental diseases in China are observed in 97% of the population, there is a catastrophic lack of dental clinics and qualified specialists. In order to somehow correct this situation, the Chinese declared September 20 - “Love Your Teeth Day”. On this day, mass explanatory work is carried out among the population about the rules of oral hygiene and the need for dental and gum treatment at the dentist.

In 1890, rubber gloves were first used in surgical dentistry, which significantly improved asepsis during operations.

In China, there are collection centers for used toothpicks. There you can hand over toothpicks - they are taken by weight, and get paid for it.

In the nineteenth century, one of the popular gifts at weddings in England was false teeth. At that time, the British believed that there was no point in treating teeth and they were ruthlessly removed at a very young age.

In 1907, the first electric drill saw the light of day.

Teeth are the only part of our body that cannot repair itself. Therefore, the abrasion of teeth with age is a natural process provided by nature.

In 1929, the first electric toothbrush was invented in America.

Curious laws exist in the USA. For example, in Vermont, a wife cannot wear dentures without her husband's written permission. And in Providence, Rhode Island, it's illegal to buy a toothbrush on Saturday.

The force of compression of the masticatory muscles is colossal. With the contraction of the muscles of both jaws, it can reach 400 kg. Under normal conditions, we chew food with a force of only 10-15 kg. The level of strength that allows you to calmly crack nuts is about 100 kg. And then, in order to prevent the destruction of periodontal tissues, a natural mechanism is activated that limits the force of compression of the jaws.

In 1956, dentists received the first automatic scalers - devices for removing tartar.

The hardest tissue in the human body is tooth enamel, which is the outer protective shell of the top of the tooth. Tooth enamel practically does not contain water, and in terms of hardness it is only slightly inferior to diamond.

In 1958, Raphael Bovin invented the first polymeric filling material based on a special resin - Bis-GMA.

Almost all calcium contained in the human body, and this is from one to one and a half kilograms, is found in the bones of the skeleton and teeth. Interacting with phosphorus, calcium makes teeth and bones strong and healthy.

Periodontal diseases are the most common in the world. About 70% of the world's population suffers from some degree of gum disease, gingivitis and periodontitis.

The widespread use of implants in modern dentistry became possible thanks to Professor Ingvar Brånemark from Sweden, who in 1965 discovered osseointegration - the process of healing and fusion of bone tissue with a titanium implant. The bioinertness of titanium has practically nullified its rejection by the body.
