An infected tooth partially cleaned with flint tools represents the oldest known dentistry, says a new international study on a 14,000-year-old molar.
The find represents the oldest archaeological example of an operative manual intervention on a pathological condition, according to researchers led by Stefano Benazzi, a paleoanthropologist at the University of Bologna.
"It predates any undisputed evidence of dental and cranial surgery, currently represented by dental drillings and cranial trephinations dating back to the Mesolithic-Neolithic period, about 9,000-7,000 years ago, " Benazzi said.
The patient was a young man, about 25 years old, living in northern Italy.
His well-preserved skeleton was found in 1988 in the Veneto Dolomitesnear Belluno, in a rock shelter burial named Ripari Villabruna.
The find was directly dated between 13,820 and 14,160 years old. It's now kept at the University of Ferrara for further studies.
"The treatment went unnoticed for all these years. The cavity was described as a simple carious lesion," Benazzi said.
