Nanotechnology Could Revolutionize The Field Of Dentistry

Nanotechnology Could Revolutionize The Field Of Dentistry | IT Support and Hardware for Clinics | Scoop.it

As a dentist, it’s important to keep up with the latest technological advances in order to have an improving dental practice, and nanotechnology is truly on the cutting edge. While these technologies are in their infancy today, they could play an integral role in the dentistry of tomorrow. Not only that, but the field of nanotechnology is advancing rapidly, which means these technologies may become easily available to dentists within the relatively near future.

 

WHAT EXACTLY IS NANOTECHNOLOGY?

 

Nanotechnology refers to devices that are between one and a hundred nanometers in diameter. A nanometer is a measurement that’s equal to one billionth of a meter. Yes, you read that right. These devices are so tiny that you would actually need a microscope to see them!

 

HOW COULD NANOTECHNOLOGY IMPROVE DENTISTRY?

 

One way that it could improve dental care is by improving the effectiveness of dental cleanings. Nanobots could be used to scrape a collection of bacteria off of teeth, which is known as the biofilm. This could allow patients to have a much whiter smile and have far better dental health overall.

 

Not only that, but these microscopic robots could even be used to clean some exceptionally difficult to reach areas of the mouth, such as the isthmus. This technology is currently being studied by the University of Pennsylvania. Nanotechnology can also be used for tissue engineering, which could make oral surgeries more effective.

 

That’s because nanotechnologies are currently being developed that could improve both healing times and patient outcomes!

 

In addition, nanotechnology has the potential to lead to improved composites. That’s because nanoparticles make it possible to simulate the cell structure of genuine teeth to a certain extent, which can allow for a much more natural-looking appearance. This technology can also allow the devices to appear far smoother than they would otherwise.

 

Nanotechnology even has the potential to improve the quality of dental imaging. That’s because nanodevices can be built to combine nanotechnology and radio technology, which can improve x-rays and other forms of dental imaging. This can allow you to get images of your patients’ teeth that are more precise than ever.

Nanotechnology in Healthcare: Getting Smaller and Smarter 

Nanotechnology in Healthcare: Getting Smaller and Smarter  | IT Support and Hardware for Clinics | Scoop.it
“Nano” means smaller than micro-sculptures on pin-point

Nanotechnology is hardly comprehensible by the average human mind, because it is in a completely different dimension. Somewhere at the molecular and atomic level. Do you remember the micro-sculptures in the eye of a needle? Compared to the nanometer, the basic unit of measurement in nanotechnology, these are still huge. A nanometer is a million times smaller than the length of an ant. A sheet of paper is about 100, 000 nanometers thick. The ratio of the Earth to a child’s marble is roughly the ratio of a meter to a nanometer.

Essentially, nanotechnology comprises science, engineering and technology conducted at the nanoscale, which is about 1 to 100 nanometers. It is basically manipulating and controlling materials at the atomic and molecular level. Amazing, right?

 

The Story of Nanotechnology – From tiny “demons” to nanorobots in bloodstreams

As part of an 1871 thought experiment Scottish physicist James Clerk Maxwell imagined tiny “demons” that could redirect atoms one at a time. However, it was a long way to go from there until the birth of nanotechnology. The term molecular engineering was actually coined by MIT professor Arthur Robert von Hippel in the 1950s. On the evening of December 29, 1959, the famous physicist Richard Feynman described in his after–dinner lecture at the annual meeting of the American Physical Society how the entire Encyclopaedia Britannica could be written on the head of a pin, and how all the world’s books could fit in a pamphlet.

Continuing the thought experiment, Kim Eric Drexler, an MIT undergraduate in the mid–1970s, envisioned that molecule–sized machines could manufacture almost anything. In his book, Drexler described nanotechnology’s future role in revolutionizing other areas of science and technology that would lead to breakthroughs in medicine, artificial intelligence, and astronomy. His idea of an “assembler” could “place atoms in almost any reasonable arrangement,” thus allowing us to build almost anything that the laws of nature will allow.

 

Later, in 1991 carbon nanotubes were discovered, which are about 100 times stronger than steel only one–sixth their weight, and have unusual heat and conductivity characteristics. The Juno spacecraft currently on its way to Jupiter uses carbon nanostructure composite to provide electrical grounding, discharge static, and reduce weight. From the beginning it was inevitable that this technology would be used in medicine. Now, we are about to reach this point.

All kinds of nano under the microscope

Nanotechnology has two basic strands. The first one is the Drexlerian molecule-sized machine, which is able to build and manipulate its environment at the atomic level. The second one is “biological” nanotech, which basically uses DNA and the machinery of life to create unique structures made of proteins or DNA (as a building material).

 

1) DNA-based origami robots

One of the most forward–thinking experiments proved that DNA–based nanorobots can be inserted into a living cockroach and later perform logical operations upon command such as releasing a molecule stored within it. Such nanorobots are also called origami robots since they can unfold and deliver drugs, could eventually be able to carry out complex programs including diagnoses or treatments. One of the most astonishing feats is the accuracy of delivery and control of these nanobots, which are equivalent to a computer system. The other one is that the same basic design principles that apply to typical full-size machine parts can also be applied to DNA.

Researchers from the Max Planck Institute have been experimenting with exceptionally micro-sized – smaller than a millimeter – robots that literally swim through your bodily fluids and could be used to deliver drugs or other medical relief in a highly-targeted way. These scallop-like microbots are designed to swim through non-Newtonian fluids, like your bloodstream, around your lymphatic system, or across the slippery goo on the surface of your eyeballs.

ETH Zurich and Technion researchers have developed an elastic “nanoswimmer” polypyrrole (Ppy) nanowire about 15 micrometers (millionths of a meter) long and 200 nanometers thick that can move through biological fluid environments at almost 15 micrometers per second. The nanoswimmers might be programmed to deliver drugs and magnetically controlled to swim through the bloodstream to target cancer cells, for example.

 

3) Ant-like nanoengines

Ant–like robots are controlled magnetically, are very fast, can locate, and use tools. Moving through even flexible surfaces they can construct three–dimensional structures at an amazing pace. They could revolutionize both biotechnology and electronics manufacturing.

University of Cambridge researchers have developed the world’s tiniest engine, made of gold nanoparticles bound together with temperature-responsive gel polymers, capable of a force per unit-weight nearly 100 times higher than any motor or muscle. Researchers named the nanomachine ANT, since as real ants, they produce large forces for their weight.

Drexel University engineers have developed a method for using electric fields to help microscopic bacteria-powered robots detect obstacles in their environment and navigate around them. It means that robots navigate with the help of electric fields, and they can be programmed into getting to a certain point or changing its route or avoid/go through objects.

Bacteria-powered robots might bring amazing changes in healthcare, which include delivering medication exactly to the point where it is needed, manipulating stem cells to direct their growth, or building a microstructure, for example.
