1
Q

what is the first step of the formation of dental tissue?

A

First, IEE elongates and become perameloblasts…and repolarize

2
Q

what is meant by repolarize?

A

nuclei moves away form the basement membrane

3
Q

what is the second step of the formation of dental tissue?

A

outermost cells of dental papilla become odontoblasts…..and repolarize and secrete a matrix

4
Q

what kind of matrix does the odontoblasts secrete?

A

collagenous matrix

5
Q

what is the third step of the formation of dental tissue?

A

preameloblasts become ameloblasts……and secrete a matrix

6
Q

what kind of matrix does the ameloblasts secrete?

A

protein matrix

7
Q

what happens to the basement membrane during the formation of dental tissues?

A

disintegrates

8
Q

what does the basement membrane become when it disintegrates?

A

DEJ (dental enamel junction)

9
Q

what are the collagenous matrix of the odontoblasts secretion?

A

predentin

dentinogenesis
