Types of cements

Zinc phosphate cement  Permanent cementation of crown, post, inlays, ortho appliance  -good compressive and tensile strength -more pulpal irritation 

-no chemical bond to tooth 

Zinc polycarboxylate cement

-Poly F 

-indicated in restoration with good retention and resistance form  -chemically bonds with tooth 

-bonds to metal (except gold) 

-minimal pulp irritation (due to larger size of polyacrylic acid molecules) 

-short working time 
GIC  -in high caries risk pt

-C/I in all ceramic crowns 

-chemically bonds to tooth

-bonds to metals (SS, base metals) except for gold 

-fluoride release 

-post op sensitivity due to initial low pH 
RMGIC -indicated for metallic and PFM restorations, zirconia and alumina-based ceramics, and lithium-disillicate pressed and milled (CAD/CAM) inlays and onlays
Resin cement  -light cure, dual cure, self cure  -translucency

-low film thickness

-adhesion that occur between tooth prep and ceramic in direct restoration
