ameloblast

[drkooks]

in test packet M
ameloblast will not differentiate from preamelobalst unless:

contact dentin
touched by odontoblastic process
touched by stratum intermedium

answer odnotoblastic process according to key
but from decks :
IEE stimulate formation of odontoblast , then formation first layer dentin, then IEE transform into ameloblast then secrete enamel..
so should not be number 1

please answer...and correct me if i am wrong
thanks

You are correct, when the IEE cells come into contact with the first layer of dentin, thats when proameloblasts differentiate into ameloblasts and enamel is laid down.

Does that mean we should not rely 100% on the answers given in the test paper key??!! as in they could be wrong too? like in this case?
