Dentistry was very developed from 9000 years ago

Scientists at the University of de Poitiers in Poitiers, France, and the Guimet Museum, Paris - while excavating an ancient graveyard discovered a total of 11 teeth were drilled, including one. Deep teeth clearly underwent a complicated process, to penetrate deep inside. On these teeth, they discovered small holes with a diameter of 1.3-3.2mm and a depth of 0.5-3.5mm. These holes are unusually shaped - conical or cylindrical - and done very carefully. All dating back to about 7,500 to 9,000 years ago.

Roberto Macchiarelli is an anthropologist of the Université de Poitiers university and the lead author of this study. He said: 'We think that this dental drilling has a medical reason, . While some teeth have been drilled more than once, 4 show signs of tooth decay . indicating that there is a possibility that it is a treatment . This process cannot be for cosmetic purposes, because its results are not easily visible '. During digging, the researchers identified nine different individuals with a total of 11 drill teeth. 'An individual has three drill teeth, while another has a tooth that has been drilled twice , ' Macchiarelli said.

When viewed under a microscope, it was found that at least in one case, not only was the tooth drilled, but the pulp cavity was also nicely reshaped. And in any case, the researchers noticed the abrasion of the teeth. That means drilling has been carried out on living people, and these teeth are then further used to chew food. The holes on the teeth, according to scientists' surveys, are filled with a sticky substance such as asphalt, probably dental fillings.

'This finding provides clear and convincing evidence that ancient people had knowledge of dental procedures on hard tooth tissues in living people , ' said Clark Spencer Larsen, a University anthropologist. The state of Ohio in the city of Columbus said so.

Macchiarelli said: 'Although this dental procedure near Mehrgarh existed for about 1,500 years, it completely disappeared with the beginning of the metal age about 7,000 years ago . There is no evidence of this procedure in cemeteries in later periods, despite their poor dental health. We cannot understand why it ended. '

It seems that many thousands of years ago, there were highly developed civilizations, advanced medical knowledge. Time is too long, while we do not keep the historical records of ancient times, so we almost do not know about these civilizations. High-level knowledge of ancient people are mysterious things that cannot be explained by narrow frameworks of prejudice. Perhaps it is time for us to study and rewrite the mysterious history of mankind.
