Engineers from the US and China made artificial tooth enamel that's even harder than the material in people's mouths—a feat that dental researchers have been chasing for many years.

These enamel rods are 4 to 8 µm in diameter and number approximately 5 to 12 million per tooth. They are surrounded by the enamelins, and the space between each rod is known as interrod enamel or ...

Technology including synchrotron X-ray diffraction and unsupervised machine learning then revealed structures within the mesoscale features, specifically, single enamel rods and the surrounding ...

In between these rods is what’s called the inter-rod enamel. Each rod is made up of about 10,000 tiny hydroxylapaptite crystals that lie side-by-side like a bunch of uncooked spaghetti.

Scientists have discovered a way to grow back tooth enamel, a development that could spell the end of fillings as a method to repair cavities. Enamel is the mineralised substance that covers the ...

The ribbon clusters, which weave together like honeycomb, are known as rods and inter-rods. When destroyed, this weave is difficult to recreate, because the cells that form enamel die as our teeth ...
