Module 4: Materials and Application Techniques

Self-Assessment Quiz

  1. When selecting dental sealant materials for school-based dental sealant programs, it is important to select sealants that:
    1. A. Contain 30 to 60 percent filler by weight.
    2. B. Have high wear resistance to increase longevity.
    3. C. Contain less than 10 percent filler by weight.
    4. D. Have the highest levels of hardness.
    5. E. Require occlusal adjustment.
  2. Which of the following statements most accurately describes sealant materials?
    1. A. According to the American Dental Association evidence-based clinical recommendations, glass-ionomer and resin-based sealants have demonstrated comparable levels of retention.
    2. B. The retention rates of auto-polymerized and light-cured sealant materials are comparable.
    3. C. Fluoride-containing sealants consistently have been shown to inhibit caries and caries-associated bacteria.
    4. D. Colored or tooth-colored sealants have demonstrated higher retention rates than clear sealants.
    5. E. Auto-polymerized sealants require more armamentarium than light-cured sealants.
  3. Which of the following statements is true?
    1. A. Bonding agents were developed to create a reliable bond between dental sealants and enamel.
    2. B. A self-etch bonding system should be routinely used during the placement of dental sealants.
    3. C. Etching for 15 to 20 seconds with 30 to 40 percent phosphoric acid is the standard for successful bonding of sealants to enamel.
    4. D. Bonding agents create the same reliable bond to dentin as to enamel when the standard acid etching technique is used.
    5. E. All of the above.
  4. Which of the following statements is most accurate?
    1. A. Evidence suggests that humans are not at risk for BPA exposure from dental sealants.
    2. B. BPA is a contaminant found in all dental sealants.
    3. C. BPA has been detected in the saliva immediately following placement of several different sealant materials.
    4. D. BPA is known to affect development and reproduction in humans.
    5. E. None of the above.
  5. Which of the following is needed to ensure that dental sealants have the highest possible level of retention?
    1. A. Teeth must be thoroughly cleaned with pumice and a handpiece before acid etching.
    2. B. Meticulous isolation of tooth surfaces to avoid saliva contamination must be maintained.
    3. C. Sealants must be applied by a dentist with help from a dental assistant.
    4. D. A self-etching bonding agent without a separate etching step should be used.
    5. E. None of the above.
