Chinese researchers found that graphene can cure cavities

Dental diseases are caused by the growth of some oral bacteria, which is the most common health problem in the world Scientists have found that a graphene oxide material can effectively eliminate these bacteria, some of which have developed antibiotic resistance The findings are published in ACS Applied Materials & interfaces Zheng Tang and his colleagues found that dentists often prescribe traditional antibiotics to patients to remove bacteria that cause cavities and gum disease However, with the increase of antibiotic resistance, new methods are needed to solve these problems, because the use of these methods will eventually lead to tooth loss Previous studies have shown that graphene oxide and graphene sheet exist in oxygen molecular group, which is a promising material in biomedical applications It can inhibit the growth of some strains, but only slightly harm mammalian cells Tang's team wanted to know whether nanotablets inhibit the growth of specific bacteria in oral diseases In the lab, the researchers tested the material's effect on three different types of bacteria that cause cavities and gum disease By destroying the cell wall and membrane of bacteria, graphene oxide effectively inhibited the growth of pathogenic bacteria The researchers therefore concluded that graphene tablets may have potential use in dental care The research was funded by the Shanghai Natural Science Foundation and the "Medical Engineering (Science) cross research" of Shanghai Jiaotong University Killing Dental Pathogens Using Antibacterial Graphene Oxide Jianliang He, Xiaodan Zhu, Zhengnan Qi, Chang Wang, Xiaojun Mao, Cailian Zhu, Zhiyan He, Mingyu Li, Zisheng Tang
Dental diseases, which are caused by the overgrowth of certain bacteria in the mouth, are among the most common health problems in the world Now scientists have discovered that a material called graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance They report the findings in the journal ACS Applied Materials & Interfaces Zisheng Tang and colleagues point out that dentists often prescribe traditio nal antibiotics to get rid of bacteria that cause tooth decay or gum disease But with the rise in antibiotic resistance, new approaches are needed to address these problems, which can lead to tooth loss Previous studies have demo nstrated that graphene oxide -- carbon nanosheets studded with oxygen groups -- is a promising material in biomedical applications It can inhibit the growth of some bacterial strains with minimal harm to mammalian cells Tang's team wanted to see if the nanosheets would also stop the specific bacteria that cause dental diseases.
