Introduction – Sensitivity is just another problem rising in all age group, a jolt of pain is been endured by large population whenever they drink hot chocolate or chilled ice-cream. Treatment for sensitive teeth is not possible by dentists though there are cures available but they don’t last very long. Research are going on that could help in curing the holes behind temperature sensitive-teeth.
Sensitivity cure has some backdrop because the coating can be removed through acidic soft drinks and continuous stiff toothbrush can also lead to damage. As the enamel wears away, it can expose inner layer called dentin. Hollow channels called tubules are present in the layer leads to nerves and those nerves sense, how the things feel and relay their assessment to the brain. This tooth enamel acts as jacket on a cold day and when exposed to cold wind it starts stinging.
Process – Dentists treat such teeth by clogging the open tubules and often use mineral with chemical name “nanohydroxyapatite.” It copies the natural character of a tooth’s enamel. However, regular erosion can strip this mineral off of the teeth swiftly. With the tubules again open, their temperature sensitivity returns and open tubules may leave a tooth more vulnerable to decay.
Researchers interceded the problem in order to solve it with their team. They are the first researcher to combine nanohydroxyapatite with a green tea extract. Other research has shown that the chemical from tea can help prevent cavities. Further ingredients are kept inside nanoparticles made from silica. Silica is the mineral that makes up most beach sand. But the sand grain varies widely in size and its shape. The silica nanoparticles is extremely tiny but the effects are much larger than particles of nanohydroxyapatite and the team hoped that the part if silica would wedge firmly inside the tubules making them hard to replace.
Experiment – the product they obtained was “white powder” which was further tested on wisdom tooth with open tubules. They covered the pores with powder and water and brushed over the clogged tubules for three minutes. They tested with multiple acid drinks and other removal methods but powder stayed sealed.
Research found still keeps other researchers of same field in doubt as the test had not been conducted on living people rather extracted teeth. Other than that there are few who are unhappy with such inventions. Still there are more to research and work on the project with no doubt.
