Development L13 - Mineralisation Flashcards
1
Q
why does dentine have more matrix compared to enamel.
A
dentine is formed first as pre-dentine and requires further mineralisation through matrix such as collagen and vesicles, which forms dentine.
whereas enamel is directly produced as enamel and does not require further matrix to form.
