  • Introduction: Review: New technologies in medicine have created the possibility of great changes and developments. Today with the help of new sciences and New hardware and materials have revolutionized healthcare. A tooth is one of the organs of the body that is in As a result of their use, they are gradually worn out and need treatment and reconstruction. Humans from the beginning with dental diseases Has been confronted and has tried to resolve it. What we see today as dentistry is the result of the evolution of this field in History has been around for a long time and now this field is equipped with modern equipment and science and very advanced materials. Nanoscience As one of the new sciences in this field, it has had very important achievements. From time immemorial to the present day, the appearance of people and having attractive white teeth has been very important for all people and with Over time, this importance has taken on a growing trend. Due to the increasing progress of different public and use Emerging technologies such as nanotechnology in the majority of this public and related industries, today thinkers and thinkers The use of nanotechnology in the form of nanorobots, nanomaterials and various nanopowders produced in dentistry and in particular Teeth whitening and increasing their durability have begun and research in this area has begun. In this research to Nano applications in dentistry of silver nanoparticles using licorice and mint plants and their antimicrobial effect The title of the factor on tooth decay has been studied
  • Methods: Introduction: Significant advances in nanotechnology in recent years have been a highly advanced branch of research focusing on Use of molecular and atomic methods to create nanoscale products that may be used in the field Other sciences have also been discovered (.) Abiodun-Solanke I, 2014 The word -nano- comes from a Greek word for The meaning of -dwarf- is derived: a nanometer of very small size equal to dividing one meter by a billionaire (9-10 Meters). It's actually the size of a small glass ball compared to an object the size of Earth. Despite There is a small scale to nanotechnology, but it certainly has a lot of potential. The basic concept of nanotechnology It is based on the use of atoms and molecules to build functional structures. The first person to use this technology as a Richard Feynman, winner of the Nobel Prize in Physics, came up with an innovative research that could revolutionize science. He in In one of his lectures in 1959, he proposed the hypothesis that molecular machines have incredible Ability to build with atomic precision (.) Zdrojewicz Z, 2015 Nano-based treatment is undoubtedly one of the main areas Researchers in nanotechnology studies are hoping that nanoscience can lead to advances in disease control Various conditions such as cancer or atherosclerosis. Each of the three main branches of nanotechnology (nanomaterials, molecular nanotechnology and Biotechnology) may become a source of invaluable discoveries and solutions in modern medicine .) Wojnicz, 2011 (to be Nanotechnology is based on structures that are ten thousand times smaller than the diameter of a human hair. Nanotechnology is not just research Makes it possible at the molecular level. Rather, it enables the fabrication of nanomaterials with new mesmerizing properties have. As a result, key nanotechnologies are one of the key technologies of the twentieth century, the century ahead. Innovative solutions to many medical and dental problems are to be found. Nano-containers used for topical pharmacy Powerful tools for effective treatment of side effects They are less negative. Implants and smart devices based on nanotechnology will conquer the market and dental treatments They will fundamentally change medicine, as has been the case in the field of materials science and medical imaging
  • Results: Conclusion Results of the study of the minimum inhibitory concentration (MIC) and the minimum lethal concentration (MBC) of these two types of nanoparticles on three Bacteria that cause tooth decay indicate that both types of nanoparticles have a growth inhibitory effect and a lethal effect on The bacteria in this study were. At low concentrations of nanoparticles, there was bacterial growth, but at increasing concentrations of nanoparticles, This led to a decrease in bacterial growth. Therefore, antibacterial effects are directly related to the concentration of biosynthetic silver nanoparticles Had. By examining the growth or non-growth of bacteria in culture medium containing different concentrations of nanoparticles, the minimum concentration Its inhibitor was identified. Comparison of the antibacterial effect of biosynthesized nanoparticles with two types of extracts shows that the antibacterial effect Bacterial nanoparticles biosynthesized with licorice extract on these bacteria, especially Streptococcus mutans are more numerous than other nanoparticles. Among the studied bacteria, resistance of Lactobacillus rhamnosus10 In contrast, more biosynthesized nanoparticles than Streptococcus and Actinomyces viscosus mutans reported. In the present study, silver nanoparticles were used using extracts of peppermint and licorice plants without the need to expend energy on raw materials. Expensive, were produced. Colloidal nanoparticles, and microscopically released microparticles; So to can even to Penetrate into bacterial cells and in this study, the nanoparticles produced have a good antimicrobial effect on oral bacteria The study showed; Therefore, based on their biological effects, the use of these nanoparticles can be used to fight infections It is effective due to the honey bacteria studied
