Formation of Dental Tissue

Question 1

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

Answer 1

First, IEE elongates and become perameloblasts…and repolarize

Question 2

what is meant by repolarize?

Answer 2

nuclei moves away form the basement membrane

Question 3

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

Answer 3

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

Question 4

what kind of matrix does the odontoblasts secrete?

Answer 4

collagenous matrix

Question 5

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

Answer 5

preameloblasts become ameloblasts……and secrete a matrix

Question 6

what kind of matrix does the ameloblasts secrete?

Answer 6

protein matrix

Question 7

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

Answer 7

disintegrates

Question 8

what does the basement membrane become when it disintegrates?

Answer 8

DEJ (dental enamel junction)

Question 9

what are the collagenous matrix of the odontoblasts secretion?

Answer 9

predentin

dentinogenesis
