Teeth imprinted upon the annals of human life

the most Important events of a person’s biography, you can recover by looking at its teeth. In dental tissues imprinted childbirth, menopause, systemic diseases and even imprisonment. This was concluded in a scientific paper published in the journal Scientific Reports.

Researchers from new York University sought to find out the number of children a woman has and the length of intervals between births in her skeleton. Such a method would be very useful to historians.

Scientists have suggested that such events should be reflected in the microstructure of the dental cement. It is the fabric that covers the bottom (submerged in the gingiva) of the tooth. From the moment when the latter is shown in the mouth, the cement regularly forms new layers. This process resembles the growth rings of trees.

the creators of the work were used for the analysis 47 of the teeth of 15 people aged 25 to 69 years. Microstructure of cement has been studied by several methods. In this case, the experts were known biographies of the donors. A large part of the necessary information was obtained from the next of kin of the subjects.

as a result, all studied female teeth enabled high precision Dating childbirth and menopause. That is, scientists have found what he was looking for.

But the dental cement gave researchers even more information than they planned to. Both women and men fabric captures systemic diseases and even periods of imprisonment.

“the Tooth is not static and dead part of the skeleton, summarizes the first author Paola Cerrito (Cerrito Paola). — It is constantly changing and responds to physiological processes.”

If the researchers ‘ findings subsequently confirmed by other teams, the Arsenal of historians will be another method that allows to judge about the way of life of long-dead people.

By the way, earlier “Conduct.Science” (nauka.vesti.ru) wrote about how the teeth can determine the sex of their owner.
