Toothache will not hurt any more by using an anesthetic

For filling or taking root canal, the dentist will put numbness into the oral tissue through a needle, it is very painful! Because of this, scientists at Sao Paolo University in Brazil have devised a method of using electricity to deliver local anesthetic , from which no needles are needed, without causing pain.

They combined two commonly used dental anesthetics, prilocaine hydrochloride and lidocaine hydrochloride, along with a polymer to create hy drogel. When adding polymer, the anesthetic mixture becomes flexible and they conduct tests on pigs.

The anesthetic effect when using an infusion line is believed to not only numb faster but also promote longer effects.

Through a process called iontophoresis , a painless electric current is transmitted through hydrogel and as a result, the amount of prilocaine hydrochloride absorbed into the tissue increases by 12 times compared to the conventional needle injection method. The anesthetic effect is believed to not only numb faster but also promote longer effects.

Professor Renata Fonseca Vianna Lopez said: "For years, our research team has begun developing novel drug delivery systems to treat many skin and eye-related diseases. and eyes are two parts that pose many challenges to all drug delivery systems, so we have focused on improving the method of drug delivery to agencies using nanotechnology, iontophoresis (using pharmaceutical ion transfer electricity). tissue) and sonophoresis (using sound waves to transmit pharmaceuticals into tissues) ".

The team is currently developing a device that uses iontophoretic technology specifically designed for use in dentistry and this technology can actually be used in many other applications.
