These types of cements are designed to act as an adhesive to hold an indirect restoration to the tooth structure or to adhere brackets to the tooth surface during orthodontic treatment.
type 1 cement. luting agents
involve materials that can be used as a restorative material, such as intermediate restorative material and dental sealants
type 2 cements
the liners and bases that are placed within the cavity preparation.
type 3 cements
what effects mixing of cements
humidity, temperature
one of the most versatile types of cement used in dentistry
glass ionomer cement
composite resin cement,has been designed especially for the following indications:
• Ceramic or porcelain inlays, onlays, crowns, and bridges
• Ceramic veneers
• Orthodontic bands
• Direct bonding of orthodontic brackets
• Metal-based crowns and bridges
phosphoric acid is an ingredient in this cement that can be irritating to the pulp. Because of the irritating factors, a liner, sealer, or desensitizer should be placed first to reduce sensitivity to the phosphoric acid.
zinc phosphate
types of dental cements
ZOE cement
glass ionomer cement
composite resin cement
Polycarboxylate Cement
zinc phosphate cement
how to dissipate heat before cementation on a prepared tooth :
spatulate cement over a wide area of a cool, dry, thick glass slab.
The ideal slab temperature
68F
This temperature allows a longer working time and permits a maximum amount of powder to be incorporated into the liquid without making the mix too thick. (zinc phosphate)
68F
It is critical that the powder be added to the liquid in very ____ ________
small increments
least irritating of all dental cements
ZOE
