PhysOrg has one more thing Neanderthals had that we have too – dental care:
A discovery of multiple toothpick grooves on teeth and signs of other manipulations by a Neanderthal of 130,000 years ago are evidence of a kind of prehistoric dentistry, according to a new study led by a University of Kansas researcher.
“As a package, this fits together as a dental problem that the Neanderthal was having and was trying to presumably treat itself, with the toothpick grooves, the breaks and also with the scratches on the premolar,” said David Frayer, professor emeritus of Anthropology. “It was an interesting connection or collection of phenomena that fit together in a way that we would expect a modern human to do. Everybody has had dental pain, and they know what it’s like to have a problem with an impacted tooth.”
The teeth and all the Krapina Neanderthal fossils were discovered more than 100 years ago from the site, which was originally excavated between 1899-1905.
However, Frayer and Radovčić in recent years have reexamined many items collected from the site.
In this case, they analyzed the teeth with a light microscope to document occlusal wear, toothpick groove formation, dentin scratches, and ante mortem, lingual enamel fractures.
Even though the teeth were isolated, previous researchers were able to reconstruct their order and location in the male or female Neanderthal’s mouth. Frayer said researchers have not recovered the mandible to look for evidence of periodontal disease, but the scratches and grooves on the teeth indicate they were likely causing irritation and discomfort for some time for this individual.
“The scratches indicate this individual was pushing something into his or her mouth to get at that twisted premolar,” Frayer said.
