A team of physicists from the National Nuclear Research University of Russia (MIVI) and the Institute of General Physics Rochorov has proposed a method to detect hidden necrosis on the surface of the enamel, as well as the hidden areas in which pathogenic bacteria accumulate, as well as the use of lasers and nanoparticles.
The results of the research published on the website "LaserPhysicsLetters" have confirmed that the early diagnosis of necrosis and small cracks in the tooth enamel is very important for the prevention of dental diseases.
Russian physicists have suggested that this process be carried out with the aid of a fluorescent laser method: to achieve this goal, the teeth are treated with a special material and then exposed to laser radiation.
Professor Victor Lucinov from the University of Mivi said in an interview with Sputnik: "The experiments were done using the laser spectrum badyzer and the fluorescent video system, and we entered the processing components Dental Valtho Sianin Aluminum (nAlPc) the
Form nanoparticles with Protelan MST-35, where both substances are widely used in cosmetics and in the production of toothpaste. "
The first studies on nAlPc interaction with the nAlPc enamel surface have been shown and, according to scientists, this is due to the low efficiency of the nAlPc surface molecules of the pathogenic microflora.
An attempt has been made to increase the sensitivity of the nanoparticles to the microflora by introducing additional components.
Interaction measurements of a composite model (colloidal nAlPc with Protelan MST-35 and additional components) with high density fluorescent enamel highlighted during enamel necrosis after three minutes of preparation on teeth (previously
Min), due to pre-activation of surface nAlPc in the presence of pathogenic microflora.
The statistical badysis of the results revealed a significant difference between the treated teeth and the teeth of the control groups. As the researchers say, this method can become very useful in dentistry for detecting necrosis in "healthy teeth".
