Study of Neanderthal Teeth Grooves Reveals Evidence of Prehistoric Dental Care

Ancient Neanderthal Dentistry: Evidence of Tooth Treatments and Toothpick Use

The discovery of numerous toothpick grooves on teeth as well as signs of other treatments by a Neanderthal of 130,000 years ago are indicators of a kind of primitive dentistry, according to a new research study led by a University of Kansas scientist.

” As a package, this meshes as a dental issue that the Neanderthal was having and was trying to treat itself, with the toothpick grooves probably, the breaks as well as additionally with the scrapes on the premolar,” claimed David Frayer, professor emeritus of Anthropology. “It was a fascinating connection or collection of phenomena that fit together in a manner that we would anticipate a contemporary human to do. Everybody has had dental pain, and they understand what it is like to have a problem with an impacted tooth.”

The Bulletin of the International Association for Paleodontology lately released the research. The researchers evaluated four separated yet connected mandibular teeth on the left side of the Neanderthal’s mouth. Frayer’s co-authors are Joseph Gatti, a Lawrence dentist; Janet Monge, of the University of Pennsylvania; and Davorka Radovčić, curator at the Croatian Natural History Museum.

The teeth were discovered at the Krapina site in Croatia, and Frayer and Radovčić have made several breakthroughs about Neanderthal life there, including a commonly acknowledged 2015 research released in PLOS ONE concerning a collection of eagle talons that consisted of cut marks and were made into an item of jewelry.

All the Krapina Neanderthal fossils, including their teeth, were identified more than 100 years ago from the site, originally excavated between 1899-1905.

However, Frayer and Radovčić, in recent times, have reviewed lots of objects gathered from the site

In this case, they evaluated the teeth with a light microscope to document occlusal wear, toothpick groove development, dentin scratches, and ante mortem, lingual enamel cracks.

Although the teeth were isolated, previous scientists rebuilt their order and location in the male or female Neanderthal’s mouth. Frayer stated that scientists had not retrieved the jaw to search for evidence of periodontal disease, yet the scratches and grooves on the teeth show they were most likely causing irritation and pain for some time for this person.

They discovered that the premolar and M3 molar were pushed out of their average positions. Connected with that, they found six toothpick grooves amongst those two teeth and both molars additionally behind them.

Neanderthal Dental Care: Evidence of Self-Treatment and Toothpick Use

” The scratches suggest this individual was pressing something right into his/her mouth to access that twisted premolar,” Frayer claimed.

He stated that the characteristics of the premolar and third molar are connected with numerous kinds of dental manipulations. Mainly because the teeth chips were on the tongue side of the teeth, and at various angles, the scientists eliminated that something occurred to the teeth after the Neanderthal passed away.

A past research study in the fossil record has found toothpick grooves going back virtually 2 million years, Frayer said. They did not distinguish what the Neanderthal would certainly have utilized to produce the toothpick grooves, but it potentially could have been a bone or stem of grass.

“It is maybe not shocking that a Neanderthal did this, however as for I understand, there is no specimen that blends all of this jointly right into a pattern that would show she or he was trying to presumably self-treat this eruption trouble,” he claimed.

The evidence from the toothpick marks and dental manipulations is likewise fascinating due to the discovery of the Krapina Neanderthals’ ability to shape eagle talons fashioned right into jewelry because people often consider Neanderthals as having “subhuman” capabilities.

” This fits into a pattern of a Neanderthal being able to modify its environment by utilizing devices,” Frayer claimed, “because the toothpick grooves, whether they are made by bones or lawn stems or that knows what, the scrapes and chips in the teeth, show us that Neanderthals were doing something inside their mouths to treat the dental irritability. Alternatively, at least this set was.”
