Incremental Carbon, Oxygen, and Strontium Isotope Data from Modern and Archaeological Human Canine and Molar Enamel.

This dataset contains high-resolution incremental enamel isotope (δ13C, δ18O, and 87Sr/86Sr) and strontium concentration ([Sr]) measurements from 28 human teeth (canines, 1st molars, and 3rd molars) sampled from 10 individuals. Nine individuals derive from a modern forensic context in Belgium, and one from the Bronze Age archaeological site of Staje, Slovenia (748–406 cal BC). The study adapts the Plomp et al. (2020) molar protocol onto first and third molars, incorporating an additional increment near the enamel–root junction, and introduces a new standardised hand-drilled incremental sampling method for canines based on their enamel growth structures. Canines produced up to four minimally overlapping increments, while molars exhibited greater overlap due to complex growth and wear. This dataset supports the development of a replicable, standardised methodology for incremental enamel isotope sampling of human canines, as well as the refinement and increased resolution of incremental enamel sampling of human molars
