Mineralisation

Question 1

What helps initial mineralisation of dentine?

Answer 1

Matrix vesicles

Question 2

After matrix vesicles, what is the subsequent mineralisation by?

Answer 2

heterogeneous nucleation

Question 3

What are the matrix vesicles

Answer 3

They are vesicles produced by cells which contain high concentrations of Ca2+ and (PO4)3-
They are released into extracellular tissue
and the crystals grow and rupture the vesicle

Question 4

What is the function of the matrix vesicles?

Answer 4

Provide an ideal microenvironment for crystal formation and growth
They help initiate mineralisation in mantle dentine and bone mineralisation
