Mineralisation Flashcards
1
Q
What helps initial mineralisation of dentine?
A
Matrix vesicles
2
Q
After matrix vesicles, what is the subsequent mineralisation by?
A
heterogeneous nucleation
3
Q
What are the matrix vesicles
A
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
4
Q
What is the function of the matrix vesicles?
A
Provide an ideal microenvironment for crystal formation and growth
They help initiate mineralisation in mantle dentine and bone mineralisation
