The first person to have historically used anaesthesia to perform surgery was a dentist!
William Thomas Green Morton was the first dentist to use anaesthesia to achieve a painless tooth extraction on September 30th 1846. He used ether as an anaesthetic agent in his own dental office. Then, on October 16, 1846, Morton participated in a surgery where Dr. John Collins Warren used ether as anaesthesia on a patient at Massachusetts General Hospital to remove a tumour in the neck without pain. Following this procedure, the news spread out globally and Morton convinced the medical world of the importance of performing surgical procedures without pain.
Victor Nunes is a retired art director living in São Paulo, Brazil. He now has a creative hobby which is very unique: he uses bits of foods and other household appliances in which he completes by drawing faces and other sketches.
His artwork is very imaginative. In this example he utilizes old toothbrushes to draw faces, people, and even what looks like to be a dentist! On his other sketches he uses everything from popcorn, scissors to bits of lettuce, designing the most funny but impressive pieces of art! He mentioned that he draws everyday, and he regularly publishes his remarkable masterpieces on his Facebook page, which will surely make you smile!
Bleach, or sodium hypochlorite, is known to remove colour, whiten or disinfect, often by oxidation. Most people associate it with its ability to clean and make whiter clothes. But bleach can be used for other purposes as well, as much for dental, medial and household purposes.
In high concentrations, bleach has an anti microbial effect and is a dentist’s best friend for root canal therapy! Liquid sodium hypochlorite quickly reacts with microbes to irreversibly denature and destroy many of them that are considered pathogens. In most countries, bleach is used by the dentist during root canal treatment to disinfect an abscessed tooth. It has also been reported that in lower concentrations, bleach can be used as a mouthwash, when very diluted in water, in adjunction with gum disease treatment.
When bleach is in very low concentrations, it can be used to treat eczema. BBC News documented a study that involved 31 children with eczema and who took baths in water that contained a small amount of bleach. All children ended up having less skin irritation. The reason bleach helped was its disinfectant ability, killing germs that usually make eczema even more challenging to treat. These microbes cause infections and alleviate eczema’s symptoms like redness, irritation and the spread of the rash to other parts of the body. Diluted bleach disinfects those germs and reduces the symptoms. But it’s important not to conduct this bleach treatment alone and be medically assisted because high concentrations of bleach can be toxic.
Another study suggested that bleach treatments can slow down aging of the skin. Older mice were given daily 30 minute baths in water containing small amounts of bleach. They have all gained a baby skin. Bleach is not only a disinfectant but also an anti inﬂammatory agent that multiplies skin cells, providing those mice with thicker epidermal layer that became thin with age. Again the study does not encourage humans to add bleach in their baths.
Breakfast is the daily meal that people have the most tendencies to skip, whether it’s for not feeling hungry, for being late at work or at school, or for having a few more minutes to sleep. But skipping this important meal can lead you to a grumpy day and, believe it or not, gain weight!
Breakfast and your metabolism
When you eat breakfast in the morning, your body receives food and tells your brain that you’re going to need to start working to digest it. This wakes up the metabolism so that your system is ready to work throughout the day. If you skip breakfast, you can actually gain weight because your body thinks that it needs to conserve the energy it has because it didn’t get any more through nutrition. Skipping breakfast therefore actually slows down your metabolism, resulting in a decrease of the amount of calories you burn throughout the day.
Breakfast and certain diseases
Many studies suggest that there is a link between not eating breakfast and obesity, high blood pressure, diabetes and heart disease. Experts aren’t certain why, but they think that people who skip breakfast are more likely to be hungrier later during day and eat larger meals. Those meals mean the body must process a larger amount of calories in a shorter amount of time. That can spike sugar levels in the blood and perhaps lead to clogged arteries.
Breakfast and your oral health
Eating a fast and sugary breakfast can be harmful for your teeth. Here are some tips in having a healthy breakfast for your body and for your mouth:
Here’s a cartoon of what most people would imagine a dental crown being like! But in reality it is not like that :)
A dental crown is a tooth-shaped “cap” that is placed over a tooth to cover it and to restore its shape, size, strength, and improve its appearance. The crown, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gums. The materials used can be either gold or porcelain. When porcelain is used, a tooth can look brand new!
When is a crown needed? Only when a tooth has had advanced trauma, cavity or root canal treatment. The more a tooth is cracked or restored with a filling, the more it is susceptible to fracturing under chewing forces, and that is when a dental crown can protect it and make it look like a real untouched tooth.
I found this great video on YouTube that shows an animation of how a root canal is done by dentist. Sometimes when I am asked to explain what a root canal is. But as they say an image is a thousand words. An animation is even much more!
The video shows two uncovered teeth: the premolar on the left has a healthy pulp tissue with nerves and blood vessels; the molar on the right has its pulp infected. The infection was caused by either a very deep cavity or trauma, and we see that it has gone beyond the ends of the roots.
The first step of the root canal is to access the infected pulp. Then the procedure consists of cleaning all of the pulp tissue contained in each of the canals. We see 2 canals here, but a molar actually contains 3 to 4 canals (sometimes even more!)
After the inside of the tooth is clean and disinfected, each canal is sealed with filling material so that the infection doesn’t appear again.
Posts are placed, followed by a crown because a tooth that has had root canal is more fragile and needs support to function properly without breaking.
In China, the Shanghai zoo has designed a special four-foot (1.2 meters) long toothbrush to clean the teeth of its hippopotamuses. The zookeepers put on a public show three times a week so visitors can watch while they do oral care with their three hippos. That job could be very challenging and unpredictable!
If your doctor has prescribed you bisphosphonates, especially if they must be injected intravenously, it is important to tell your dentist because, in this case, it is contra-indicated to proceed with any surgical treatment in the mouth, including extractions and dental implants.
Bisphosphonates are drugs that prevent the loss of bone mass in certain medical conditions. Doctors prescribe it in tablets for women in menopause or pre-menopause. Bisphosphonate tablets are also indicated for people with Paget’s disease (misshaped bones).
These drugs can also be injected intravenously during therapy of bone metastases of breast cancer. In this case, some patients may develop in their mouths a condition called osteonecrosis. This condition is described by bone death following a blood circulation problem.
The link between osteonecrosis and bisphosphonates is not yet well understood. It is important then to inform your dentist if you take these drugs especially if intravenously. Your dentist can then check for any signs of osteonecrosis in the mouth and treat if needed. Furthermore, it’s strongly believed that keeping a good oral hygiene can reduce the risk of getting osteonecrosis of the jaw.
