CT scans conducted throughout numerous research laboratories at the U-M Institution of Dentistry were made use of to figure out the annual development increments in the tusks. As tusks are basically front teeth that continue to expand out of the mouth, dentin can be recuperated from the inside of the tusk as well as, using a little drill bit, Cherney and also group were able to grind out half-millimeterwide examples of dentin from various regular monthly intervals of the tusks' growth.

Interestingly, whilst tusks are just located on male Oriental elephants, both the man and also female African elephants have them. Much of the interior of a tusk is made up of an extremely gotten scaffolding of dentine.
