文摘

Enamel stained by post-mortem processes may have a similar appearance to MIH. Our diagnostic guide enables to identify developmental hypomineralisation of enamel to taphonomic discolorations. Hypomineralised enamel has higher phosphate/β-carbonate ratio and lower mineral density. Taphonomic discolorations are highlighted using X-ray fluorescence analyses.
