All measurements are decreased by surface erosion or corrosion of enamel in the type and are therefore 1–2 mm less than they would be in an undamaged individual. As nearly as can be judged the removal of enamel has affected all tooth dimensions about equally, so that the same proportionate relations are retained as between any two given teeth.
