What is that how can a tooth survive the years and bear any intelligible mark of the molecules on its side when bone and other soft tissue have long since decayed? In the case of ancient-DNA, teeth ...

Teeth may look simple on the outside, but inside they are complex structures made of minerals, proteins, and tiny channels ...

Teeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure allows teeth to ...

Advanced imaging revealed a sharp zinc increase toward the tooth pulp, tracking higher dentine porosity. The results could ...

A new study has uncovered a rare behavior in the material of the teeth of the Atlantic wolffish. This material is osteodentin, the tissue at the tooth’s core, which appears to shrink in every ...

A team of international researchers has discovered that the structure of dentin works to protect against cracks and increases the resistance of teeth in a new study in the journal Nano Letters (May ...
