Washington: Tiny particles of plaque removed from the teeth of our great grandfathers may help decode their dietary habits and preferences, says a study.G. Richard Scott, associate professor of anthropology at the College of Liberal Arts, University of Nevada, Reno, obtained samples of dental plaque from 58 skeletons buried in the Cathedral of Santa Maria in northern Spain dating from the 11th to 19th centuries to conduct research on the diet of this ancient population.After his initial findings met with mixed results, he decided to send five samples to Simon R. Poulson at the Nevada University`s Stable Isotope Lab, in the expectation they might contain enough carbon and nitrogen to allow them to estimate stable isotope ratios, said a university statement.
