Archaeological significance

[edit]

Dental calculus has been shown to contain well preserved DNA and protein in archaeological samples.[1] The information these molecules contain can reveal information about the oral microbiome of the host and the presence of pathogens.[2] It is also possible to identify dietary sources[3] as well as study dietary shifts.[4]
