Cold Atmospheric Plasma as a magic wand for dental desinfection

 

Providing an innovative tool for fighting against harmful bacteria in dentistry is a daily task of many dentists and researchers around the world. As bacteria comes into contact with teeth enamel, cavities can form and bacteria can reach the inner pulpy region called dentin. This process often leads to the damage of the enamel and dentin which obliges dentists to take away the damaged area then disinfect the region with chemical products before applying a resin to replace the empty volume. 

According to researchers in France, the future of dental disinfection will be a safe and painless technology based on Cold Atmospheric Plasma discharges. Low-temperature plasmas can remove these bacteria and avoid the formation of cavities while no pain is felt by the patient during the process. “Dentin protection could be achieved by using cold plasma in a safe and painless process,” says Dr Malle Chabron from Aix-Marseille University.

Dr Chabron currently collaborates with the local startup Plasmawise in Marseille that develops Cold Atmospheric Plasma devices for specific use in dentistry. The French company and its University partners have a already developed a new device, named pWise and made it available for researchers to make the initial tests. Plasmawise is starting commercializing the device at a competitive price compared to laser equipment for similar applications which is already available for about €10,000.
