how to prevent calcification on teeth

10 oldest objects ever found number 10 sex toy for thousands of years, phallic objects have been used symbolically as a means to boost fertility and ward off evil spirits - but their use as sexual aids has a long history, too. in 2005, german scientists discovered one of the world's oldest sculpted phalluses - 20cm of polished siltstone lovingly created around 28,000 years ago. the stone member was discovered in hohle fels cave near


ulm, swabia, by a tã¼bingen university team. it bears the scars of having been used to knap flints and was reassembled from 14 fragments. despite this abuse, and in a delicious leap of imagination, it's been speculated that the life-size phallus may have been used as a prehistoric sex toy. number 9 chewing gum spitting out chewing gum on the street is a widely despised habit that can land you with a fine. but our tendency to discard


the half-masticated blob appears to date back at least 5,000 years, it was revealed. in 2007, a 5,000-year-old piece of chewing gum, the oldest ever discovered, was found by a british archaeology student in finland. the neolithic gum, made from birch bark tar, had tooth prints in it. "birch bark tar contains phenols, which are antiseptic compounds. it is generally believed that neolithic people found that by chewing this stuff if they had gum infections it helped to treat the condition," said trevor brown from the university of derby.


number 8 a map in 2009 the oldest known map was discovered carved on a hand-sized sandstone rock. the small rock with etchings of mountains, rivers and even animals was found in a cave called abauntz lamizulo in the navarre region of northern spain, an area in the middle of the basque country. it is believed that the map of the area where the rock was found was used by magdalenian hunter-gatherers who were only a few centuries removed from the ice age. marking territory in a rapidly changing landscape would have been very important


to these semi-nomadic people, who may have used the map to navigate or to tell the tale of a previous hunt. number 7 dna the altamura man became the oldest neanderthal to have his dna extracted by researchers. about 150,000 years ago, a neanderthal man fell into a well in what is now southern italy. in 1993, spelunkers spied his skull staring blankly back at them from its nook in the lamalunga


cave, deep under the town of altamura. while the man's intact skull and jumbled pile of bones made for a great specimen, they were wedged into a panoply of stalactites and stony globules deposited by water dripping over them for tens of thousands of years. researchers decided not to rescue the bones, for fear that trying to ease them out of the cave's calcified grip would shatter them and ruin altamura man.


so, they left him forever a caveman. in 2015, researchers had a small change of heart they took a chip from his right shoulder blade to the lab for research. metrics taken of his skeleton confirm altamura man was a homo neanderthalensis. the scientists hope they will be able to sequence his dna, to find out more about the evolution of all hominids – including us. scientists have for the first time revealed the face of altamura man, whose bones were found fused to the walls of


a cave in lamalunga, near altamura, in southern italy. with a short and stocky body, the altamura man had a jutting brow, an elongated cranium and a very big nose. number 6 trousers i thought that my ex-girlfriend owned the world’s oldest trousers. but now it appears that an even older pair of trousers—some 3,300 years older—has come to light. in 2014, a team of archaeologists, excavated tombs in yanghai in western china. there, they uncovered the remains of two nomadic


herders and a pair of trousers with woven patterns, which were dated to be 3,000 years old. these are the oldest known pair of trousers found to date. the discovery also supports the theory about an evolution from tunics to trousers, which were more practical for horse-riders of the time. number 5 leather shoe "it is astonishing how much this shoe resembles a modern shoe!" said a famous designer. stuffed with grass, perhaps as an insulator or an early shoe tree,


the 5,500-year-old moccasin-like shoe was found exceptionally well preserved— thanks to a surfeit of sheep dung—during a 2010 dig in an armenian cave. about as big as a current women's size seven (u.s.), the shoe was likely tailor-made for the right foot of its owner. radiocarbon dated to about 3500 b.c., during armenia's copper age, the prehistoric shoe is compressed in the heel and toe area, likely due to miles upon miles of walking. however, the shoe is by no means worn out. number 4


artificial eyeball according to a 2006 report, iranian archaeologists in "burnt city" announced the unprecedented discovery of an artificial eyeball, dated to 4,800 years ago, in this historic site. the eyeball belonged to a sturdy woman who was between 25 to 30 years of age at the time of death, and its material consisted of natural tar mixed with animal fat. studies on the eyeball also suggest the formation of an abscess in the eyelid due to long-term contact with the eyeball. moreover, remaining eyelid tissues are still evident on this artificial eyeball.


number 3 prosthetic toe a false toe buried with a mummy 3000 years ago is thought to be the oldest discovered prosthetic device and has passed a test to see whether it could have been used as an aid for walking. university of manchester researchers copied the wooden toe and a volunteer with missing toes, wearing the kind of sandals worn in ancient egypt, tested the replica on a pressure measurement system. the toe turned out to be a practical walking device, rather than cosmetic.


the wood and leather toe had been buried with a woman believed to have lived between 950bc and 710bc. number 2 complaint letter the oldest known complaint letter goes back 3750 years. the letter, inscribed on an ancient clay tablet and dating from 1750 b.c., corresponds to the period of old babylon. the complaint was made by a certain nanni to ea-nasir regarding the delivery of the wrong grade of copper ore after a gulf voyage and about misdirection and delay of a further delivery.


good customer service has always been hard to find! number 1 alien skull is this an alien skull? perhaps, but scientists believe this skull found in mexico is a human skull that is the result of a process called artificial cranial deformation. it’s usually done when a child is an infant and the skull is softest and they bind the skull with either wood or cloth for about 6 months.


why they do this, no one really knows, but it is thought that it was a means of signifying status. even more surprising is the fact that the practice still continues to this day in some places such as vanuatu which is an island near fiji. however some researchers believed that the elongated skulls actually belong to a race of humans which no longer exists.
