Chapter 45 Dental Cements Quiz & Flashcards

Study Notes

Dental Cements Overview

Spatulate: The process of mixing using a flexible metal or plastic instrument to achieve a uniform consistency.
Exothermic: Describes a chemical reaction that releases heat during the process.
Provisional: Temporary tooth coverage used for a limited duration until permanent restoration is applied.

Types and Functions

Cement: A versatile dental material used to secure indirect restorations, applicable for both temporary and permanent use.
Luting Agent: Another term for dental cement, functioning primarily to adhere restorations to tooth structures.
Provisional coverage: Involves the use of temporary cement during dental procedures, preparing the tray setup accordingly.

Mixing and Application Techniques

Smallest powder increment: The initial amount of powder introduced to zinc phosphate liquid during mixing should be minimal for optimal consistency.
Type II Zinc Oxide-Eugenol (ZOE): Specifically formulated for permanent cementation applications.
Treated paper pad: The ideal mixing surface for ZOE to ensure proper formulation and functionality.

Product Forms

Two tubes of paste: Temp bond, a type of dental cement, is commercially available in this dual-component form.
Phosphoric acid: The primary liquid component in zinc phosphate, critical for its adhesive properties.
Cool glass slab: Recommended method to dissipate heat generated during the zinc phosphate mixing process, preventing thermal damage.

Application Process

Overfill in gold crowns: An important technique in the placement of permanent cement to ensure complete coverage and proper adhesion.
Ezqueeze bottle and calibrated syringe: Common methods of dispensing polycarboxylate cement liquid, ensuring accurate volume for use.
Glossy appearance: Properly mixed polycarboxylate cement should have a smooth, shiny finish indicating correct consistency.

Material Properties and Uses

Glass ionomer material: Confirmed to be effective for restorations, offering benefits like adhesion to dentin and enamel.
Calcium: Contains an ingredient in glass ionomer cement powder that aids in preventing recurrent decay, enhancing long-term dental health.
Resin cement under metal castings: Affirmative capability allows its use for supporting metal restorations securely.
Composite Resin: Preferred choice for cementing ceramic veneers, due to compatibility and aesthetic considerations.
