This is where calcium combines with phosphate in our bones to create the mineral crystal hydroxyapatite.

The more hydroxyapatite crystals detected, the healthier the bones are.

Previous analyses of the adhesive found inorganic materials similar to cement, and hydroxyapatite, a mineral obtained from ground teeth and bones.

As with earlier construction of artificial enamels, the team built its new material from wires of hydroxyapatite—the same mineral that makes up real enamel.

Bindslev and colleagues used hydroxyapatite—the main mineral in tartar—and mixed in known amounts of legal drugs like caffeine, nicotine, and cannabidiol, as well as controlled substances like oxycodone, cocaine, and heroin.
