Chattering squirrels, charming coypus, and tail-slapping beavers -- along with some other rodents -- have orange-brown front teeth. Researchers have produced high-resolution images of rodent incisors, providing an atomic-level view of the teeth's ingenious enamel and its coating.
Chattering squirrels, charming coypus, and tail-slapping beavers -- along with some other rodents -- have orange-brown front teeth. Researchers have produced high-resolution images of rodent incisors, providing an atomic-level view of the teeth's ingenious enamel and its coating.
The researchers collected incisors from rodents that live in different environments: beavers, coypus, squirrels, marmots, rats, voles and mice. To investigate the structure, elemental composition and color transmission of the enamel, thin slices were taken from different sections of the teeth and prepared for imaging with optical microscopy, 3D focused ion beam tomography and scanning transmission electron microscopy.
The microstructure of the iron-rich enamel contains elongated nanometer-sized pockets filled with small amounts of the ferrihydrite-like material, which contribute acid resistance even though the filled pockets account for less than 2% of the volume of iron-rich enamel. The researchers suggest that adding small amounts of ferrihydrite-like or other colorless biocompatible iron minerals to dental care products could provide exceptional protection for human tooth enamel. In addition, incorporating small amounts of iron hydroxides into synthetic enamel could produce longer-lasting restorations for human teeth.
