The renaissance of dentistry dates back 9,000 years ago, according to the findings reported in a scientific review of a recent issue of Nature. At least nine people living in a Neolithic village in western Pakistan had carved cavities in their molars during the course of their lives.
Four of the teeth showed signs of caries associated with the carved cavity. The research team reported that by closely evaluating the teeth the carving was “amazingly effective” in removing the decayed tooth tissue. They believe that a small drill was used to carve the teeth of the patients and probably arose from the carving of ornamental stones.
Fine drill tips were discovered among the stones. Merger patients are not common in the anthropological record, according to Dr. Machiavelli, who noted that similar dental work does not repeat until around 1100 AD among the Anasazi Indians of the southwestern United States and around the year. 1500 DC in Europe.
