Highlights • 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.
