ABSTRACT
Recent studies have shown that chemical and physical approaches are increasingly being used for dental materials analysis and to develop full details and information on the biological circumstances of Humans groupings, prehistoric diets, and the etiology of different illnesses. As a result, estimates of elements levels in teeth can provide insight into the discovery as well as the pathogenesis of different ailments among ancient and contemporary Egyptians. The level of lead, aluminum, and strontium in enamel of teeth from human Egyptian embalmment dated to the new kingdom (1085 BC) from the Sakkara region, as well as newly extracted sound teeth from the same region's inhabitants, were analyzed. The laser involved breakdown spectroscopy (LIBS) approach was used to estimate the elements. Using the measured LIBS spectra, the elemental content was calculated. Lead, aluminum, and strontium content levels in ancient Egyptian teeth have been found to be higher than they have been in recent years, according to current data. These data suggested that an increase in lead and aluminum levels in ancient Egyptian teeth was due to direct exposure to such elements, which increased contamination during that time duration. Because of the increased strontium content, ancient Egyptian teeth are more calcified than modern teeth.
