Module 4 Post-Test Self-Assessment

  1. When selecting dental sealant materials for school-based dental sealant programs, it is important to select sealants that:
    1. Contain 30 to 60 percent filler by weight.
    2. Have high wear resistance to increase longevity.
    3. Contain less than 10 percent filler by weight.
    4. Have the highest levels of hardness.
    5. Require occlusal adjustment.

  2. Which of the following statements most accurately describes sealant materials?
    1. Glass-ionomer and resin-based sealants have demonstrated comparable levels of retention.
    2. Auto-polymerized and light-cured sealants are comparable in retention.
    3. Fluoride-containing sealants consistently have been shown to inhibit caries and caries-associated bacteria.
    4. Colored or tooth-colored sealants have demonstrated higher retention rates than clear sealants.
    5. Auto-polymerized sealants require more armamentarium than light-cured sealants.

  3. Which of the following statements is true?
    1. Bonding agents were developed to create a reliable bond between sealants and enamel.
    2. A self-etch bonding system should be routinely used during the placement of sealants.
    3. The standard 15- to 20-second etching with 30 to 40 percent phosphoric acid is the standard for successful bonding of sealants to enamel.
    4. Bonding agents create the same reliable bond to dentin as to enamel when the standard acid etching technique is used.
    5. All of the above.

  4. Which of the following statements is most accurate?
    1. Evidence suggests that humans are not at risk for BPA exposure from sealants.
    2. BPA is a contaminant found in all sealants.
    3. BPA has been detected in the saliva immediately following placement of several different sealant materials.
    4. BPA is known to affect development and reproduction in humans.
    5. None of the above.

  5. Which of the following is needed to ensure that dental sealants have the highest possible level of retention?
    1. Teeth must be thoroughly cleaned with pumice and a handpiece before acid etching.
    2. Meticulous isolation of tooth surfaces from saliva contamination must be maintained.
    3. Sealants must be applied by a dentist with help from a dental assistant.
    4. A self-etching bonding agent without a separate etching step should be used.
    5. None of the above.

  6. Which of the following statements is accurate?
    1. Short-term retention checks can be used to detect clinical problems related to sealant materials, equipment, or application technique.
    2. Short-term retention checks can be used to identify early any potential problems with sealant retention.
    3. ODH expects 100 percent retention at the time that short-term retention checks are conducted.
    4. It is best for short-term retention checks to be performed by a dentist or dental hygienist who did not place the sealants.
    5. All of the above.
