2. Properties of Material
ADA has teamed up to classify dental cements according to:
Properties of Material
Uses of Material

3. Classification of Cements
Restorative
Liner and base
Luting agents

4. Every cement must be assessed for its
biocompatibility
safety
effectiveness.
has suitable physical properties for its intended use

5. 3 main Categories
2014

6. Zinc-oxide Eugenol
Zinc phosphate
Polycarboxylate
Glass ionomer

7. sets in contact with water
Powder and Liquid
ZnOE
2 paste system
E free
With E
sets in contact with water
Single paste

8. ZNO E mixes on glass slab with spatula ratio (4 :1)
Thin mix
for temp. cementation
Thick mix
for temp. filling

9. Characteristic Bacteriostatic Low thermal diffusivity Water soluble
High sealing ability
Weak cement
Opaque

10. Indications Temporary cementation Temporary filling
Indirect pulp capping
Endodontic sealer
Surgical pack

11. Light-cured Ca(OH)2 paste – resin matrix
2 paste Calcium hydroxide+ di-salicylate

12. not adhere to the tooth structure
pulpal stem cells
not adhere to the tooth structure
Opaque
soluble
Bacteriostatic
Weak cement

13. Direct & indirect pulp capping Cavity liner Temporary cementation
Applications
Endodontic sealer
Direct & indirect pulp capping
Cavity liner
Temporary cementation

14. Phosphoric acid Zn

15. cavity base /temp. filling
Zn phosphate mixes on glass slab with spatula liquid add in small increments
Thin mix
for cementation
Thick mix
cavity base /temp. filling

16. Characteristic Stronger than ZOE and weaker than GI
Dycal requires before Zn Phosphate
Mechanical retained
thin mix dissolves more than the thick mix

17. Application
Orthodontic band
Base
Temporary filling
Dentine build up

18. ZINC POLYCARBOXYLATE CEMENT
Zn and Poly-acrylic acid
Freeze dried acid is blended with the powder

19. Characteristic insulate thermal and electrical irritations
Its strength is comparable to that of zinc phosphate cement
Chemically adhere
Ca(OH)2 liner is needed in deep cavities
More soluble in water than zinc phosphate cement

20. Application
Orthodontic band
Base
Temporary filling
Dentine build up

21. GIC
Luting
Final restoration
Base and liner
Fissure sealant
Ortho band
Core build up
