Graphene Oxide Can Effectively Eliminates Bacteria Associated with Dental Diseases

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 graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance.




Zisheng Tang and colleagues point out that dentists often prescribe traditional 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 demonstrated 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.



In the lab, the researchers tested the material against three different species of bacteria that are linked to tooth decay and gum disease. By destroying the bacterial cell walls and membranes, graphene oxide could effectively slowed the growth of the pathogens.
