Overuse of Toothpicks may Have Changed Jaw Structure in Some Ancient Humans

Ann Margvelashvili, a paleoanthropologist at the University of Zurich's Anthropological Institute and Museum in Switzerland, said fossil findings in human evolution are often represented by mandibles, because typically they are better preserved than any other parts of the skeleton except teeth during fossilization processes.

Scientists, who analyzed how jawbones from modern hunter-gatherers from Australia and Greenland could vary, compared them with Dmanisi teeth and jaws.

Margvelashvili said that Dmanisi hominids show the first clear case of overusing the toothpick, which led to infection.
