Our colleague Gregor Kapun has been involved in research on rodent teeth by analyzing and understanding the 3D distribution of “ferrihydride pockets” in rodent teeth using advanced electron microscopy techniques – FIB-SEM 3D tomography – including 3D reconstruction at high resolutions.

Chattering squirrels, charming coypus, and tail-slapping beavers — along with some other rodents — have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the teeth’s ingenious enamel and its coating. They discovered tiny pockets of iron-rich materials in the enamel that form a protective shield for the teeth but, importantly, don’t contribute to the orange-brown hue — new insights that could improve human dentistry.
