A History of Dentistry

I ran into an interesting article concerning the history of dentistry. I copied and pasted it below. I felt it was worth blogging about. 

Be glad you were born in the twentieth century!

 
Judging from what archaeologists have learned from examining the bones and teeth of long-dead humans, people have been bothered by dental problems for thousands of years. Simply put, many of these ancient folk had holes in their teeth and probably suffered from toothaches and also abscesses, whose pain can be excruciating. At least in some places, they did what they could. Evidence of the use of dental drills has been found in Neolithic graves in Pakistan. (The Neolithic Age lasted from 12,000 to 5,000 years ago.) But whether this procedure brought relief to anyone is open to conjecture, of course.

The earliest writing regarding toothaches took place about 5,000 years ago in Mesopotamia. Etched on cuneiform tablets, the Sumerians wrote of demons and tooth worms causing tooth decay. People would pray to gods such as Shamash, Anu or Ea to cure them of their painful oral afflictions.
Then about 2250 B.C.E. (before the Common Era), physicians began treating toothaches with something other than invocations to some god or another. A mixture of henbane and beeswax was heated by a hot iron, and then the smoke directed to the decayed tooth. The cavity was then treated with a cement of powdered henbane seed and gum mastic.

The first dentists appeared in Egypt about 2600 B.C.E. (about the time the Pyramids were built), and one of the best was named Hesi-Re, considered the "chief toother." However, there's no evidence that these dentists did anything more than treat toothaches and oral lesions.

The Chinese of about 5,000 years ago treated toothaches with substances such as arsenic, which typically killed the pain and perhaps the patient as well. Acupuncture was also used for tooth problems; 26 body sites were designated for relief of toothache.

As for the much revered ancient Greeks (Hippocrates, Aesculapius and Aristotle, et al.), they believed that all disease, including tooth decay, was caused by an imbalance of the four bodily fluids or humors. This was how bleeding began as a treatment, and it continued to be used in dentistry until the early years of the twentieth century!

The first dental bridges were produced by the Etruscans, who flourished between 1000 and 400 B.C.E in what is now Italy. They connected rings of gold with natural teeth, and the bridges found in mouths around the planet today are descendants of these prostheses.

The Romans, conquerors of the Etruscans, invented gold crowns, methods for securing loose teeth and created artificial replacements made of bone, wood and ivory. Moreover, by the first century C.E. many Roman physicians specialized in dentistry, particularly extractions. A common Roman treatment for toothache was gargling with a mouthful of urine - one's own or somebody else's. And during the first half of the first century C.E. the first cavity was reportedly filled by one Aulus Cornelius Celsus, who used a mixture of lint and lead pressed into the depression with forceps.
By 659 C.E. the Chinese were filling cavities with a mixture of silver, tin and mercury, or amalgam, as dentists call it, about 1,000 years before Western dentists began using it.

In the Middle Ages, dentistry seemed to have regressed somewhat, particularly in Europe. The prevailing theory of this time was that tooth decay was caused by tooth worms, and there were various ways of defeating these little devils, or so people thought. Blood-letting was a common treatment, as well as leeching, blistering of the skin, administering laxatives, placing garlic cloves in the ear or destroying the dental nerve by using a red-hot iron or strong acid. Interestingly, in medieval England, teeth were removed as a form of punishment.

In England during the middle 1600s, thousands of deaths were attributed to botched dental procedures, mainly because of infections resulting from unsanitary conditions. Also, many people lost their teeth because of scurvy, a deficiency of vitamin C.

In addition to scurvy ravaging people's teeth, many people began consuming large quantities of processed sugar, which caused an exponential increase in tooth decay. Reacting to such matters, William Shakespeare often mentioned dental pains and foul breath in his various plays.
In Italy of the 1400s, a physician named Giovanni d'Arcoli began filling teeth with gold leaf, admirably progressive for the time, but he also advocated cautery, bloodletting and laxatives as toothache remedies.

In 1530, Medicine for the Teeth by Anonymous was the first book dedicated entirely to dentistry. Written in German, rather than Latin, it was widely used as a training manual for many years to come.

In the 1700s, John Hunter of England began transplanting human teeth. Hunter would pay people for their healthy teeth and then implant them in the mouths of his patients. These implanted teeth would be tied to adjoining teeth until they stabilized. However, they rarely lasted for longer than a few months.

In the American colonies of the middle 1700s, many dentists implanted dentures and bridges. Patriot Paul Revere was one such dentist. Revere was the first dentist to identify a corpse using postmortem dental forensics. John Greenwood worked on George Washington's teeth, which tormented the poor man his entire adult life, though he never had wooden teeth; they were made of hippo ivory. Moreover, during the American Revolution, scavengers would rob graves for teeth to be used as dentures.

Dentistry began to take its modern form in 1728 when Frenchman, Pierre Fauchard, published his book The Surgeon Dentist, a comprehensive work whose use eventually crowned Fauchard as the father of modern dentistry.

In England during the middle 1800s, anybody could become a dentist without any training whatsoever, though some people paid as much as $1,000 to learn the trade.

The first root canals were performed in the United States in the 1830s. Arsenic was used to devitalize the pulp or root, which was then scooped out, all of this done without anesthetic.

In 1773, nitrous oxide (a.k.a. laughing gas) was discovered by chemist Joseph Priestly, but it wasn't used as an anesthetic until 1844. About the same time, ether was also used as an anesthetic in dentistry. Then chloroform drew people's attention, first used as an anesthetic in 1847.
In the Western dentistry of the time, early amalgam fillings contained a mixture of silver and mercury. By itself mercury is quite toxic. If it doesn't bind completely with the silver, leakage can occur, harming the patient. And these fillings were poured at a temperature of over 200 degrees, certainly very hot when applied to the exposed nerves in one's teeth!

In America in the late 1800s, itinerant dentist Edgar "Painless" Parker made a show of extracting teeth and, in England, William Hartley, a.k.a. Sequah, could extract as many as eight teeth per minute!

The first set of porcelain dentures were produced in France in 1788. These were the first successful artificial teeth produced from inorganic matter. In the middle 1800s, cheap Vulcanite rubber was used for dentures. And acrylic resins became widely used when rubber became scarce during World War Two.

Dentists began using cocaine as a local anesthetic in the late 1800s. Then it was replaced by Novocain in 1905. About the same time, people began using toothbrushes and toothpaste.
In 1895, Wilhelm Roentgen discovered X-rays (or ultraviolet rays), revolutionizing science and medicine. Just a year later the first radiographs of teeth were made. Tragically though, many people were harmed by the use of X-rays until precautions such as shielding became standard.
In 1906, Charles Land was credited for developing the first porcelain jacket crowns.

Around 1900, fluoride, an actual component in tooth enamel, began being used to fight tooth decay in the United States, and now most of the water in this country's water supply is fluoridated. Some people think fluoridation may have long-term health effects, though this has never been proven. However, using "too much" has been blamed for staining teeth brown.

In the early decades of the 1900s, teeth whitening became the rage. Unfortunately, many of these applications either didn't work or were harmful to teeth. In the early 1930s, a whitening agent called Tartaroff contained hydrochloric acid, which indeed whitened the teeth but also destroyed tooth enamel in the process.

The first electrically driven dentist drill was produced in 1870. And then in the 1950s the first ultra speed drills came into production, working at upwards of 400,000 rpm. These days, some dentists use laser drills, which provide much greater precision and therefore help prevent degradation of the teeth being repaired.

Nowadays, composite plastic resins, developed for dentistry in the 1980s, can be used to fill teeth rather than gold or amalgam, whose use is much more obvious and not as esthetically pleasing, though the metallic material tends to cost less and lasts longer.

Well, the history of dentistry continues to evolve as we speak. Perhaps one day genetic manipulation or the application of some miracle formula will eliminate tooth decay altogether. But until that time, though the physical pain may not be as great as in the olden days, the pain in one's wallet, so to speak, will nevertheless continue for the foreseeable future.

My Semester Break

Hey everyone,

So im just coming off my break and currently trying to get back in the swing of things with school. My break was without a doubt one of the most amazing experiences of my young life. Have a read about our trip to Zermatt, Switzerland and I also included a little bit about this past Friday night at the end of the blog. Enjoy!

Our Trip:

The gentlemen partaking in this trip of a lifetime were Benjamin Quinn, Keith Sproul and myself. Pictured below at one of the million summits: 

Myself, Ben and Keith at 13000ft!
Switzerland, in general is an amazing country. It was the best quality snowboarding I have ever done. The snow was perfect and the weather was perfect. Not too cold and not too hot. We only had one day when there was a blizzard and even than we only lost 1/4 of a day of snowboarding.

Good shot of how small the village looks (only half way up the mountain)
This mountain was huge. You would not believe exactly how big Zermatt is. Because its so big we spent a lot of time on chair lifts and gondolas. From the bottom to the very top took at least half an hour to 45 minutes. It equally took as long to snowboard down to the bottom. The grooming of the trails were 2nd to none. All trails were in immaculate condition and the terrain was so vast that you could go off trail for miles and still get to where you want to go. My only con was that none of the trails were overly challenging. Zermatt is more tailored toward family and intermediate skiers/ snowboarders. Regardless of this, everyday was literally a day in paradise for us.
This is known as Glacier Paradise, Heaven on Earth

The mighty Matterhorn piercing the clouds
I represented the X-Ring a lot. Still so proud to be a Xaverian Alum
StFX!

My first powder experience, I was so happy!
The apartment we stayed in was also fantastic. We all had to sleep in one big (I use that term loosely) room but luckily none of us were snorers. We had a kitchen with a stove so to save money we cooked a lot of our own food. It was Ben's birthday when we were there so on that night we cooked up some nice salmon with lemon and mashed potatoes. Simple but delicious. Not buying food every night definitely cut down on costs for us. In addition, the service at the apartment was tremendous. The gentleman owning all the apartments was named Richard and when he spoke he sounded just like gold member off Austin Powers :), he was the nicest guy though. He would deliver fresh bread to our room at 7:00am each morning and the day of Ben's birthday he delivered a cake to our room as well (with candles). I suppose for the money we paid that was the way we should have been served but none the less we couldn't have been more happy with the service.
Outdoor rink in the middle of the village. I wish I brought my skates to show the swiss how its done!

Fun facts about Zermatt:

1. The village itself is full of rich people who like to let you know they're rich

2. They have street meat vendors in the village but you can't get a coke to drink, you can only get champagne.

3. The village is completely car free, they use little electric buggies as taxis so people can get around.

4. The village is situated 1600 feet about sea level

5. Justin Timberlake was there...we think

6. We gathered that Swiss people are the most efficient people in the world. If they say "I'll meet you at 11:07", as the clock strikes 11:07 they show up. Extremely punctual and kind people made the trip pleasant for all 3 of us. Oh and their chocolate is to die for. Those of you that know me well can imagine the field day I had in the chocolate aisle at the grocery store.

7. To falsify number 6 a little, I broke up a fight in the middle of the street between a 50 year old and a 65 year old, I believe they were arguing about cab fair.

8. Zermatt actually lies directly on the Italian border. So on the 3rd day we were there we snowboarded into Italy and had real pasta for lunch.....As expected, the food was great and the service was shit. This was a full day expedition.

(I am noticing that as i type all of this up I am enforcing a lot of stereotypes hahaha)

Birthday Celebrations:



This past Friday (March the 9th) we celebrated 5 peoples birthday in our DDS class. It was an amazing night, we went out for a nice dinner and then myself and my friend Arnold left dinner early so we could get birthday cakes ready and let the other people joining the party into my apartment.  The birthday people walked in and we surprised them and sung happy birthday etc. After a couple hours at my place we had another surprise up our sleeves and had everybody go outside to find a limo waiting there! We rode around downtown Poznan for an hour in the back of a limo and had a blast. A little cheezy I know, but everybody had a great time and it was something none of us will soon forget. Shout out to Arnold and Martyna for helping out and making it possible!



















That is all I have for now, The next couple months are crunch time and school needs to once again become the focus. I will tentatively be coming home to Canada on June 30th but that is of course subject to change. Hope all from home are doing well and missing you guys a tonne. Until next time! Cheers
