Which of the following is a commonly used abrasive agent in toothpaste formulations?
Calcium carbonate
Silica
Xanthan gum
Sodium fluoride
Silica acts as a mild abrasive in toothpaste, helping remove plaque and stains. It is effective without damaging enamel.
What is the primary role of fluoride in dental care products?
Act as a surfactant
Strengthen enamel
Kill oral bacteria
Whiten teeth
Fluoride promotes remineralization of enamel and prevents demineralization. It forms fluoroapatite, making enamel more resistant to acid attack.
Which ingredient is commonly added to toothpaste as a humectant to prevent drying?
Titanium dioxide
Carbamide peroxide
Glycerin
Sodium bicarbonate
Glycerin retains moisture in toothpaste, preventing it from drying out. It helps maintain consistency and improves texture.
Chlorhexidine gluconate in mouthwash primarily serves what function?
Flavor enhancer
Whitening agent
Fluoride source
Antibacterial agent
Chlorhexidine gluconate is a potent antibacterial agent that reduces oral bacteria. It is used to control plaque and gingivitis.
Which active ingredient in desensitizing toothpaste helps reduce nerve sensitivity?
Sodium silicate
Fluorosilicate
Potassium nitrate
Calcium hydroxide
Potassium nitrate works by depolarizing nerve cells, reducing sensitivity signals. It requires regular use to maintain the effect.
What is the role of carboxymethyl cellulose in alginate impression materials?
Cross-linking agent
Thickening agent
Setting accelerator
Surfactant
Carboxymethyl cellulose increases viscosity, stabilizing the impression material and improving tear strength. It helps maintain the shape of the mold until set.
What is the primary function of a silane coupling agent in composite resin formulations?
Provide color stability
Neutralize acidity
Initiate polymerization
Bond filler particles to resin matrix
Silane coupling agents form a chemical bond between inorganic filler particles and the organic resin matrix. This improves mechanical properties and durability of composite restorations.
Compared to conventional glass ionomer, resin-modified glass ionomer cements primarily benefit from which feature?
Reduced bond strength
Higher film thickness
Lower fluoride release
Light-curing capability
Resin-modified glass ionomers contain resin components allowing light-curing, which accelerates set time and improves early strength. They still release fluoride similar to conventional formulations.
Which component in mouthrinses like Listerine provides antimicrobial activity?
Sodium fluoride
Essential oils
Cetylpyridinium chloride
Triclosan
Essential oils such as thymol, eucalyptol, and menthol disrupt bacterial cell walls, providing broad-spectrum antimicrobial action. They are the active agents in many mouthrinses.
The RDA value on a toothpaste label indicates what?
Residual decay activity
Relative dentin abrasion
Remineralization daily allowance
Reactive dental acid
RDA stands for Relative Dentin Abrasion, measuring how abrasive a toothpaste is on dentin. Manufacturers use it to ensure safe levels of abrasion for daily use.
What is a common limitation of alginate impression materials regarding dimensional stability?
High tear strength
Long shelf-life in moisture
Rapid polymerization upon mixing
Susceptibility to syneresis and imbibition
Alginate materials lose water over time (syneresis) or absorb moisture (imbibition), causing dimensional changes. This limits how long impressions can be stored before pouring.
Sodium lauryl sulfate in toothpaste primarily serves as what type of ingredient?
Surfactant
Preservative
Abrasive
Sweetener
Sodium lauryl sulfate is a surfactant that lowers surface tension, promoting foaming and aiding in dispersion of ingredients. It helps distribute toothpaste and bind particles during brushing.
What factor most directly influences the working time of polyether impression materials?
Filler particle size
Ambient temperature and humidity
Type of mixing tip
Polymerization inhibitor concentration
Polyether impression materials are sensitive to temperature and humidity, which affect the rate of polymerization. Controlled environmental conditions ensure predictable working and setting times.
Which sweetening agent in sugar-free dental products is contraindicated for patients with phenylketonuria (PKU)?
Saccharin
Sorbitol
Xylitol
Aspartame
Aspartame metabolizes to phenylalanine, harmful for PKU patients. Xylitol and sorbitol are sugar alcohols that are safe in PKU.
For a high-caries-risk patient, which fluoride varnish concentration is most appropriate?
5% sodium fluoride
2% sodium fluoride
1.23% acidulated phosphate fluoride
0.1% sodium fluoride
5% sodium fluoride varnish delivers 22,600 ppm fluoride, recommended for high-caries-risk patients. It adheres well to enamel and provides prolonged fluoride release.
How does bioactive glass in toothpaste formulations promote enamel remineralization?
Produces reactive oxygen species that strengthen enamel
Lowers pH to dissolve enamel minerals
Releases calcium and phosphate ions to form hydroxycarbonate apatite layer
Creates mechanical abrasion to expose dentin
Bioactive glass gradually releases calcium and phosphate ions, which deposit as hydroxycarbonate apatite on enamel surfaces. This layer restores mineral content and provides resistance to acid attack.
In resin composites, increasing filler loading predominantly affects which property?
Reduces viscosity for better flow
Increases polymerization shrinkage
Decreases radiopacity
Enhances mechanical strength and reduces shrinkage
Higher filler loading increases filler-resin ratio, improving mechanical properties and reducing overall polymerization shrinkage. However, it can increase viscosity, requiring adjustments for handling.
What role does the initiator/co-initiator system play in light-cured resin materials?
Neutralizes acidic by-products
Catalyzes filler particle dispersion
Acts as a thermal stabilizer
Converts monomers into cross-linked polymers upon light activation
The initiator/co-initiator system absorbs light energy and generates free radicals, initiating polymerization of resin monomers. This leads to the formation of a cross-linked polymer network that hardens the material.
Evaluating pH's impact on chlorhexidine mouthwash stability, which statement is most accurate?
Near-neutral pH (5.5-7) maintains stability and efficacy
Highly alkaline conditions (pH >11) enhance activity
pH above 9 prevents precipitation
Stability is optimal at pH 2-3
Chlorhexidine is most stable and effective at near-neutral pH (around 5.5-7), maintaining its cationic form. Extreme pH can reduce solubility or cause degradation of active molecules.
Why are pH cycling models important when assessing new toothpaste formulations for enamel remineralization?
They prevent bacterial contamination during testing
They replicate daily pH fluctuations in the oral environment, simulating demineralization and remineralization cycles
They allow testing of tooth whitening effects exclusively
They eliminate the need for ion release measurement
pH cycling models mimic the dynamic acidic challenges and neutralizing periods experienced by teeth, providing a realistic assessment of remineralization potential. This helps predict clinical performance of toothpaste formulations.
