What are features of DEJ?
20um transistional zone
specialized aprismatic enamel(diffuse damage) and Mantle dentin
provides broad function zone
controlled failure mechanisms
: surface area, gradation, interlocking
triple helix, chains left, wrap right
What is diff btwn PTD and ITD?
peri is dense smooth
inter is disorganized granualar
dominent enamel protein
self assembly nanospheres->guide crystallization
migratory vectors weave
isoforms give rise to different size crystallites so they pack better with more complexity.
