Evidence of some of the world’s oldest dentistry has been found on a 14,000-year-old molar.
Using scanning electron microscopy the researchers uncovered peculiar striations in the internal surface of the large cavity.
“They were the result of a variety of gestures and movements associated with slicing a microlithic point in different directions,” Benazzi said.
Experimental tests carried out on the enamel of three molars using wood, bone and microlithic points confirmed the striations are characteristic of scratching and chipping.
