26 Questions
26 multiple choice questions about coronal polishing.
| Term | Definition |
|---|---|
| Sharp-edged particles are more abrasive than dull, round particles. | Particle shape |
| The larger the and harder the particles, the faster the abrasion rate of heat production increases | Type of abrasive |
| Mild abrasive for polishing used in some prophy paste and also found in whitening toothpaste | Calcium carbonate (chalk, whitening, calcite) |
| Popular fluoride added to commercially prepared prophylaxis paste to replace fluoride lost in the enamel surface during the polishing procedure due to abrasive. Not used if teeth are to receive | Fluoride prophylaxis paste |
| Materials that cut or grind a surface leaving grooves and a rough surface | Abrasives |
| Fine, medium, coarse | Grit size |
| Used to polish porcelain restorations. Its pure form is called aluminum oxide | Emery (corundum) |
| Fairly abrasive for use on heavy stains | Silex |
| Used on porcelain surfaces | Diamond |
| Larger the particle = more abrasive | Particle size |
| More material, the faster the abrasive works | Amount of abrasive material |
| Red in color and used in gold restorations | Rouge |
| Resistance of particles to break up the polish; therefore, less material is used | Particle strength |
| Very fine polishing agent used on enamel and metallic restorations mixed with water, alcohol, or glycerin | |
| Using a medium size grit abrasive followed by a fine polishing paste | |
| Harder the particle - abrade faster. Must be harder than the surface being polished | |
| The firmer the pressure, the more abrasive. Frictional heat increases | |
| Used for light stain removal | |
| Process for using fine abrasive to produce a smooth, glossy surface | |
| Highly abrasive. Not used on exposed dentin, tooth color restorations, gold restorations or root surfaces | |
| Stain removal and polishing used on gold restorations, exposed dentin, tooth colored restorations and enamel | |
| The dryer the abrasive the more abrasive they are | |
| Used on more persistent stains (ex. Tobacco) Not used on root surfaces | |
| Relatively coarse material used to remove stains from enamel; should be followed by a fine polishing agent. Not used on exposed dentin, tooth color restorations or gold restorations | |
| Rate of abrasion increased accordingly. Increases heat production | |
| Least abrasive. Removes soft deposits and light stains. Not used on root surfaces |
