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.
