Question 551 · LDEK · Glass ionomer cements
Choose correct statements regarding glass-ionomer cements:
1) they are used for caries stabilization;
2) hardening of glass-ionomers is based on acid-base reaction;
3) blast effect concerns the bonding of the cement with phosphate and calcium ions of enamel and dentin;
4) amount of fluoride ions released from glass-ionomer cements does not change overtime.
The correct answer is:
2) hardening of glass-ionomers is based on acid-base reaction;

- B. 2,3.
- C. 3,4.
- D. 1,4.
- E. 1,3.
Hint
Recall the setting reaction of glass ionomers and what the term 'burst' describes in their fluoride release profile.
