Archaeologists find proof of tooth decay and cavities in 9,000-year-old discoveries
It is clear that many problems that were once prevalent in ancient times are no longer a problem today and vice versa. However, there are some problems that, as archaeologists have found, have been actually been present for a very long time, such as tooth decay.
Researchers from the Cardinal Stefan Wyszyński University in Warsaw, Poland, have found a form of tooth decay that was present 9,000 years ago, also known as carious lesions in Mesolithic jaws and teeth in northeastern Poland. This would suggest that during the hunter-gatherer periods of man, the diet was made up of mostly berries, fruit, and honey as well as fish.
Speaking to the Polish Press Agency, Professor Jacek Tomczyk discussed the process that led to their finding and that they found the cavities in the jaws and teeth of a child and two adults dating back to the Mesolithic period. “For our analysis, we used a fluorescent camera and various X-ray imaging methods. This way we detected caries that were not a great loss of enamel.”
Further analysis showed that freshwater fish largely made up the diet of these people at the time. There is a chance that this prevented further tooth decay. Freshwater fish have some amounts of arginine, which has anti-cavity properties and is added to certain kinds of toothpaste. Aside from freshwater fish, their diet also included other plant-based food like forest plants and mushrooms.
Previously, Bible expert Professor Tom Meyer claims that there is archaeological evidence to prove the accounts of the fall of the walls of Jericho. Speaking to Express, Professor Meyer explained that despite being a small city, Jericho was heavily fortified and said that researchers have also reached the same conclusion as to how did the city of Jericho actually fell when the city was excavated. First, the walls fell down, then the city within burned to the ground and was eventually deserted.
The mudbrick that made up the walls fell outwards, and researchers found a pile of these mudbricks along the part of the wall that was unearthed. Professor Meyer notes that Jericho was the only ancient city that archaeologists found where its walls completely collapsed. There was also evidence of a fire when a different group of researchers found rooms of ash and collapsed roof timbers as well as burnt jars.
