Toothpaste
What active ingredient in toothpaste helps prevent dental caries?
B. Fluoride
Which factor is most frequently the cause for sealant failure?
Saliva contamination
Which surface(s) are included in a Class IV restorations?
Incisive angle of anterior teeth
True or False? Liners provide thermal protection?
FALSE. Liners do NOT provide thermal protection. The function of a liner is to create a barrier between the dentin and restorative material which minimizes ingress of oral fluids.
Which alloy is least likely to be found in amalgam?
A. Aluminum B. Copper C. Tin D. Zinc
A. Aluminum
What action does arginine - based compounds provide in desensitizing toothpaste?
Bind to mucosal tissues B. Block nerve impulses C. Disrupt bacterial cell walls D. Seal dentin tubules
D. Seal dentin tubules
What appearance should be visible on the tooth after applying dental etchant for 15-20 seconds?
Frosted appearance.The frosted look indicates that the enamel surface has been properly etched, which helps to increase its surface area. This allows dental bonding materials to bond more effectively to the tooth, creating a stronger attachment for restorations such as sealants.
Which restorative material is most likely used for a Class IV restoration?
Composite
Which of the following materials is commonly used as a dental liner for its ability to promote reparative dentin formation?
A. Zinc oxide-eugenol (ZOE)
B. Calcium hydroxide
C. Resin composite
D. Amalgam
B. Calcium hydroxide
Which special property do glass ionomers have that differentiate them from other dental materials?
A. Affordable
B. Matches the tooth color
C. Provides strength
D. Releases fluoride
D. Releases fluoride
Which active ingredient is commonly used in desensitizing toothpaste to provide a physical barrier over sensitive areas?
A. Calcium Carbonate
B. Chlorhexidine
C. Novamin
D. Triclosan
C. Novamin
Composite resin
Which G.V. Black classification of restoration involves only the proximal surface of anterior teeth?
Class III
Which material is a primary component of dental cements?
A. Carbon B. Copper C. Nitrogen D. Zinc Oxide
D. Zinc Oxide
Why is titanium commonly used for dental implants?
Osseointegration (Bone Bonding)
Which active ingredient is found in tartar control toothpastes?
A. Carbide Peroxide B. Pyrophosphate C. Strontium Chloride D. Triclosan
Carbide Peroxide: Tooth whitening
Triclosan: Gum care
Strontium Chloride: Desensitizing
Which benefit does light-cured composites have over self-cured?
Requires no mixing
What G.V. Black classification of restoration might require a wooden wedge?
Class II - involves the proximal surfaces of the posterior teeth
When placing restoration close to the pulp, which goes first? Liner? Varnish? or Base?
Liner -> Base -> Varnish
What dental material is used to fabricate night guards and retainers?
Acrylic resin
What is the standardized measurement of the abrasive effect of toothpaste on enamel or dentin?
Relative Dentin Abrasively - RDA. The higher the RDA, the more abrasive to the enamel/dentin; a RDA of 250 or less is accepted by the ADA for toothpaste.
Up to what length of time, in years, do pit and fissure sealants typically last?
10 years!!!!!
What G.V. Black classification of caries applies to the cervical third of the tooth?
Class V
Which of the following is a primary benefit of using low-strength dental bases in restorative dentistry?
A. They act as a barrier against thermal conductivity.
B. They provide stimulation of reparative dentin.
C. They significantly increase the strength of the final restoration.
D. They reduce the risk of tooth discoloration.
B. They provide stimulation of reparative dentin.
HIGH-strength dental bases release fluoride!
Which material is commonly used as a base for dental composites?
A. Glass
B. Bis-GMA
C. Gold
D. Polyethylene
B. Bis-GMA - used because of its hardness and strength
