Toothbrush harder to build than Mars rover part is ‘breakthrough’ in dental care, Hong Kong inventor says - rotating electric toothbrush

The Hong Kong inventor who made space tools for the Mars probe
He said a "breakthrough" was designed to completely change the way you brush your teeth. Dr Ng Tze-
Chu En, honorary associate professor at the Faculty of Dentistry at the University of Hong Kong, and Jin Lijian, a dental professor, announced their NJ toothbrush on Monday, saying it was the only brush in the world to target all the surfaces of the teeth.
They have applied for patents to the United States and international and are negotiating with toothbrush companies to market their inventions.
Ng, a trade dentist who is known as a garage inventor, designed a pair of planetary rock grip for the European Space Agency (ESA)
Mars lander.
The new toothbrush is simple in design but harder to make than space tools, he said.
"In such a small space, all functions must be correct.
It's harder than the Mars exploration tool because you can add motors and electronics, but it's all mechanical for this tool.
The toothbrush, he admits, is "not as interesting as the Mars project," but it could have a bigger impact because it would have a direct impact on more people.
Ng said that their design was "a breakthrough in dental care," which had different lengths of bristles installed on rotating hinges.
This will help to clean all surfaces of the teeth, including hard teethto-
Reach areas such as the molars teeth and the back of the gum line.
Ng said that the current method of brushing teeth, even if there is an electric toothbrush on the market, is random and requires hand dexterity.
The couple said that their invention did all the work for users, brushing their teeth for only one to two minutes and also preventing wear and tear on the surface of the teeth.
According to them, the development of the tool uses computer drawing.
Ng says the use includes moving the brush along the "arch track" from "one side of the mouth to the other, don't stop ".
He added that they hope the invention will prevent gum disease in about 0. 538 billion people around the world.
On 2001, a Ministry of Health survey found that patients under the age of 12 in Hong Kong have shown a risk of gum disease.
"You can prevent tooth decay when you use a regular toothbrush.
However, when you brush your teeth, you will suffer from gum disease . "
But he said it was not easy to convince toothbrush companies to change their designs.
