William Addis of England is credited
with creating the first mass-produced toothbrush in 1780. In 1770 he
had been placed in jail for causing a riot. While in prison, he
decided that the method for teeth brushing of the time – rubbing a
rag on one's teeth with soot and salt – could be improved. So he
took a small animal bone, drilled small holes in it, obtained some
bristles from a guard, tied them in tufts, then passed the bristles
through the holes on the bone and glued them.
The first patent for a toothbrush was by H. N. Wadsworth in 1850 in
the United States, which was mass produced in USA in 1885. The
rather advanced design had a bone handle with holes bored into it
for the Siberian Boar hair bristles. Boar wasn't an ideal material;
it retained bacteria, it didn't dry well, and the bristles would
often fall out of the brush. It wasn't until World War II, however,
that the concept of brushing teeth really caught on in the U.S.
cause the US troops had it as part of daily duty to clean their
Natural bristles (from animal hair) were replaced by synthetic
fibers, usually nylon, by DuPont in 1938. The first nylon bristle
toothbrush, made with nylon yarn, went on sale on February 24, 1938.
The first electric toothbrush, the Broxodent, was introduced by the
Bristol-Myers Company (now Bristol-Myers Squibb) at the centennial
of the American Dental Association in 1959.
In January 2003, the toothbrush was selected as the number one
invention Americans could not live without, beating out the
automobile, computer, cell phone, and microwave oven, according to
the Lemelson-MIT Invention Index.
Information technology revolution did also take the good toothbrush
in the swing
Tech savvy guys always come up with some new
stuff. Something innovative. The new one to add to the rack is
a USB tooth brush. I guess all of you know what is USB, Universal
Serial Bus (USB) is a serial bus standard to interface devices. USB
was designed to allow peripherals to be connected using a single
standardized interface socket and to improve plug-and-play
capabilities by allowing devices to be connected and disconnected
without rebooting the computer (hot swapping). Other convenient
features include providing power to low-consumption devices without
the need for an external power supply and allowing many devices to
be used without requiring manufacturer specific, individual device
drivers to be installed.
AKIBA PC HOTLINE has shown intel executive
Jason ChipZiller's dream and vision to make USB 2.0 "truly
ubiquitous" . The USB tooth brush box contains
a battery-powered pin to USB cable directly
linked to the structure, and will not use batteries.
APPLE the leader in IT world has something to give
to dentistry too . The Apple Toothbrush will include the first
user-friendly application of DRM—dental rights management. Using its
patented FairBrush technology, each Apple Toothbrush will be locked
to a single Apple ID. The device will be wildly popular because
nobody likes it when someone else uses their toothbrush
The other tooth brush innovation latest to add up
is a "Solar powered tooth brush" that does not require a toothpaste
This Proton Toothbrush will brush without a
toothpaste. In 1822, an Estonian physician named Thomas Seebeck
inadvertently discovered that the junction between two dissimilar
metals will generate a voltage between the metals which depends on
the temperature. The electric potential created by combining
precious and base metals in this Toothbrush helps
provide better plaque removal than conventional toothbrushes. The
magnesium copper metal combination generates a voltage of 0.8 – 1.8
and an electric current of 2 – 1200 mA in water, in addition to H 3
O 2 - negative ions. Bacteria in the mouth may be sterilized by
voltage over 1.3, which creates an electric sterilization effect.
This electron activity helps remove dental plaque from areas where
conventional toothbrushes cannot reach.
So keep advising proper brshing to your patients
and enjoy this issue.
A man went to his dentist because he feels
something wrong in his mouth. The dentist examines him and says,
"That new upper plate I put in for you six months ago is eroding.
What have you been eating?"
The man replies, "All I can think of is that about four months ago
my wife made some asparagus and put some stuff on it that was
delicious...Hollandaise sauce. I loved it so much I now put it on
everything --- meat, toast, fish, vegetables, everything."
"Well," says the dentist, "that's probably the problem. Hollandaise
sauce is made with lots of lemon juice, which is highly corrosive.
It's eaten away your upper plate. I'll make you a new plate, and
this time use chrome."
"Why chrome?" asks the patient.
To which the dentist replies, "It's simple. Everyone knows that --
there's no plate like chrome for the Hollandaise!"
