On the Increasing Fragility of Human Teeth with Age: A Deep-Ultraviolet Resonance Raman Study

Ultraviolet resonance Raman spectroscopy (UVRRS) using 244 nm excitation was used to investigate the impact of aging on human dentin. The intensity of a spectroscopic feature from the peptide bonds in the collagen increases with tissue age, similar to a finding reported previously for human cortical bone.
