How chewing affects teeth on the nanoscale

[breckjensen]

Food leaves permanent traces on teeth. Cows chewing on grass, tigers tearing up a piece of raw meat and humans munching on tortilla chips all end up with tiny scratches and nicks on the enamel of their teeth. Examining these marks on the microscale—what researchers call "microwear"—has led to new discoveries about the nature of teeth and the diet of our human ancestors.
Now a team of researchers has taken an even closer look at teeth and documented the effects of chewing on the nano-sized structures that make up tooth enamel. Insights from their research have broad implications.

Thanks!

I didn't find the right solution from the Internet.
