      dentin is approximately 70% mineralized while enamel is between 96
and 97% mineralized. As it only has 3-4% organic material, enamel will
disintegrate if tissue is decalcified. If preparing ground sections of
teeth that are not embedded in plastic,   the brittleness of the enamel
limits how thin the section can be ground. Also it is common problem
that the thinner the section, the more liable for you to introduce
artifactual cracks in the enamel.
