Rooting for efficiency—vibrating rotary file speeds up root canal treatments

By Lisa McDonald / January 12, 2024

Though modern root canal treatments are not overly painful thanks to advancements in medical technology, the need to frequently clean the rotary file can lengthen procedure time. Researchers at Fraunhofer Institute for Ceramic Technologies and Systems IKTS created a file that features both rotational and vibrational motion, which reduces the amount of cleaning required.

Copper-glazed ceramic tiles combat bacteria through hydrophobicity and ion dissolution

By Lisa McDonald / April 28, 2023

Antibacterial ceramic coatings that inactivate or destroy pathogens typically suffer from poor durability. Instead, antibacterial coatings based on hydrophobicity, which inhibits bacterial adhesion, may be more durable. Researchers in South Korea demonstrated the potential of copper-glazed ceramic tiles to maintain long-lasting antibacterial efficiency through a combination of hydrophobicity and bacterial killing via ion dissolution.

Self-sufficient glucose monitoring system successfully manages diabetes in mice

By Lisa McDonald / April 21, 2023

Continuous glucose monitoring systems can help alleviate the mental burden of diabetes management, but there are limitations to powering current systems. Researchers at ETH Zurich developed a self-sufficient glucose monitoring system that not only registers excess glucose but initiates the release of insulin into the blood. They successfully tested the device in mice.
