Next Generation of Dental Materials Could Prevent Cavities With Antibacterial Nano-Particles

Researchers from the National University of Science and Technology MISIS have come up with a technology that could prevent dental cavities dramatically — all by providing teeth with “antibacterial therapy.”

The researchers have created a mix of nanoparticles — iron, titanium, zinc among other metals.

This new formula will have widespread application in dentistry and other medical fields, researchers say. In dentistry, the formula acts as an antibiotic compound but without the common side-effects.

Dentists are faced with a fundamental problem that every dental filling can easily breed bacteria that causes more tooth decay later. Tiny cavities and cracks can form in the filling itself.

Research indicates the ultra-low concentrations of the metals in this new formula provide long-term antibacterial protection in the dental filling — to prevent cavity-causing bacteria. Also, the additives improve the bond between the restored tooth and the filling material.
