Develop a system with laser technology that "shields" against tooth decay.
Proponents of this new tool underline that 60 and 90% of schoolchildren worldwide dental caries and it is very unlikely to find someone who has not suffered a cavity along his life. In fact, the World Health Organization categorizes decay as most common oral disease with periodontal disease and the most widespread in the world.
The problem is that between, buy kinah aion, 5 and 8% of the surface of dental enamel has a natural porosity that can penetrate the lactic acid bacterial plaque and decay, causing tooth decay.
But from now on, they said, the dreaded visit to the dentist for some tooth fillings may be avoided, according to the results of scientific research conducted over more than three years in the, sto credits, past decade, and resumed, at present, by the Valencian company Stoma Laser Technology on human teeth in vitro.
Aido Innovation Center, an expert in industrial optical technology, ratified for the testing of human teeth in vitro, performed in his laboratory, the most suitable type of laser to fuse the enamel and remove the porosity of the tooth surface.
As a result of "armoring" of, sto energy credits, the enamel prevents lactic acid responsible for tooth decay, the tooth penetrates. "This new technology involves a great global progress against what is already known in this field," explained Dr. Torres, director of R & D of Laser Technology Stoma.
Casting trials of tooth enamel to prevent cavities and are being carried out, as a pilot, a dental clinic in Valencia on adult patients. In addition, the Department of Orthodontics, Faculty of Medicine and Dentistry of Valencia plans to experience this method in children and young people later this year.
In particular, children should undergo several sessions throughout childhood, while the teeth are erupting or growth. About the 18-20 years of age is considered that the tooth has already reached its full eruption, so the laser can be casting the entire exposed surface of the tooth.
The use of this type of laser in dentistry has many more advantages applied, for example, the reconstruction of broken and decayed teeth. This time, the technological innovation lies in providing the tooth hydroxyapatite, a mineral composed of calcium phosphate crystal that is part of the enamel that covers the teeth.
So far, the reconstruction of teeth and fillings are being carried out with acrylic, porcelain and composites, but has never used the actual mineral that makes up the enamel, thus avoiding any difference with the tooth in their mechanical properties, physico-chemical and aesthetic.
At this point of the R + D department is also working Biomaterials, School of Industrial Engineering, University Politecnica de Catalunya, experts in research on calcium phosphates.
As the research "in vitro" was moving it was found that, in addition to eliminate forever the possibility of dental caries following the application of the laser increases the hardness of enamel mineralization and its resistance to acid. In addition, this laser can be used in the treatment ofmobility of the teeth, contributing to their preservation and fixation, Microfund their points of contact. SENSITIVITY
In the same line, the laser technology applied to dentistry also allows improving the performance of endodontics in the devitalization teeth. Likewise, tooth sensitivity deleted permanently and dental aesthetics can be used for permanent bleaching vital teeth with pathological and normal colors, without requiring any type of bleaching agent, such as in the removal of tattoos dermatology skin.
The project has the support of the Generalitat Valenciana through the Institute of Small and Medium Industry Valenciana (Impiva) and the European Regional Development Fund (ERDF).
