Abrasives

Practice for state test

QuestionAnswer
Silex A fairly abrasive agent which would be used to clean more heavily stained surfaces
Superfine Silex Used to remove light stains from the tooth's enamel, fine abrasive
Fine Pumice A mildly abrasive agent, used for a persistent stain such as a tobacco stain
Zirconium Silicate Used to clean and polish tooth surfaces, a highly effective material and does not abrade the tooth's enamel. Non-abrasive
Chalk Would also be known as whiting, chalk is formed of precipitated calcium carbonate (is often incorporated into toothpaste and other polishing pastes for whitening purpose)
Commercial premixed preparations These are what are commonly used during a polishing, individually wrapped and flavored polishes. Available in different grits; some being made specially for esthetic restorations
Fluoride prophylaxis pastes A replacement for some of the fluoride that is lost from the surface layer during the polishing process. These pastes are not to be used as a substitute for topical fluoride. NOT TO BE USED PRIOR TO PLACING SEALANTS, BRACKETS, OR ORTHO BANDS.
Sapphire or diamond polishing paste Is only recommended to polish porcelain
Aluminum Oxide paste Recommended for use on filled hybrid composites and resin restorations
Flour of pumice Used to remove stains from enamel, is relatively coarse and should be followed by a fine polishing agent. Not to be used on exposed dentin, tooth-colored restorations, or gold because of the high abrasiveness
Which of the following is a commonly used abrasive material in dental polishing pastes and compounds Aluminum oxide
What natural material was historically used as an abrasive in dental polishing? Cuttle
What volcanic rock powder is frequently used as an abrasive in dental polishing pastes? Pumice
Which substance is often used in traditional air powder polishing for dental cleaning? Sodium Biocarbonate
Which compound is utilized in dental polishing pastes for its abrasive properties? Tin oxide
Fluoride prophylaxis pastes Commercially prepared pastes with the addition of fluoride that replace some fluoride that is lost during the polishing process.
Silex Fairly abrasive; used for cleaning more heavily stained tooth surfaces.
Zirconium silicate Used for cleaning and polishing tooth surfaces (this material is highly effective and does not abrade the tooth enamel). Good for gold, exposed dentin and tooth colored restorations.
Air polishing Uses a specially designed hand piece with a nozzle that delivers a slurry of warm water and sodium bicarbonate.
Tin Oxide Used in combination with water, to make a precious metal polishing paste for high polishing on amalgam and precious metals.
Superfine Silex Used for removal of light stains on tooth enamel.
Flour of Pumice Made from volcanic glass; used to polish enamel, gold foil, dental amalgam, finishing acrylic denture bases in the dental laboratory
Fine Pumice Mildly abrasive; used for more persistent stains, such as tobacco stains.
Bristle brushes Made from natural or synthetic materials and may be used to remove stains from the deep pits and fissures of enamel surfaces. Can cause cuts. Not recommended for use on exposed cementum or dentin because these surfaces are soft and are easily grooved.
Chalk Also known as whiting; chalk is precipitated calcium carbonate.
Commercial premixed prepareations Contain an abrasive, water, humectant, a binder, flavoring agents, and color.
Dental tape A wide thread similar to dental floss, composed of fine, short silk or synthetic fibers.
