Or
Describe the Zinc Phosphate Cement
Answer:

Uses of Zinc Phosphate Cement:

• Luting of restorations (cementations)
• High strength bases
• Temporary restorations
• Luting of orthodontic bands and brackets.

Properties Of Zinc Phosphate Cement

Advantages of Zinc Phosphate Cement:

• Zinc phosphate cement is stronger (103.5 MPa) than zinc oxide-eugenol.
• The strength is sufficient when used as a base or luting agent.
• Its modulus of elasticity is high. This makes it stiff and resistant to elastic deformation.
• This is necessary when it is employed as a luting agent for restorations that are subjected to high masticatory stresses.
• Zinc phosphate cement is a good thermal insulator and may be effective in reducing galvanic effects.

Use Of Zinc Phosphate Cement In Dentistry

Disadvantages of Phosphate Cement:

• When phosphate cement is exposed to the oral environment,
• For example, Temporary restorations, its bitterness and low strength cause it to fracture and disintegrate.
• Tensile strength is weaker, thus making it brittle.
• In the mouth, they show greater disintegration over a period of time.

Zinc Phosphate Cement Pros And Cons

• Pulp response is moderate. The acidity is high at the time of insertion due to phosphoric acid.
• Phosphate Cement has no anti-cariogenic properties.
• Phosphate Cement shows poor aesthetics.
• Phosphate Cement does not show chemical adhesion.
