Question 1

What is the proper curing time for a photopolymerized sealant?&#10;A) 20 to 60 seconds&#10;B) 60 to 90 seconds&#10;C) 20 to 40 seconds&#10;D) 30 to 40 seconds

Accepted Answer

The proper curing time for a photopolymerized sealant is typically 20 to 60 seconds, depending on the specific product and light intensity used.

Question 2

Dental sealants reduce dental caries for which of the following reasons?&#10;A) They promote remineralization of the tooth structure.&#10;B) They act as a physical barrier to dental decay.&#10;C) They have long retention rates.&#10;D) All of the above are correct.

Accepted Answer

Dental sealants primarily reduce dental caries by acting as a physical barrier that prevents food particles and bacteria from accumulating in the grooves of the teeth, thereby reducing the risk of decay.

Question 3

Which of the following filler materials is considered more durable?&#10;A) Microfill particles&#10;B) Ground quartz particles&#10;C) BIS-GMA&#10;D) Silane-coated filler particles

Accepted Answer

Silane-coated filler particles are considered more durable because the silane coating creates a strong bond between the filler particles and the resin matrix, which improves the overall strength and durability of the composite material.

Question 4

Which of the following is part of the assessment phase of the dental hygiene process?&#10;A) Placing a sealant&#10;B) Applying a fluoride treatment&#10;C) Detecting a possible carious lesion&#10;D) Giving oral hygiene instruction

Accepted Answer

Detecting a possible carious lesion is part of the assessment phase of the dental hygiene process. This phase involves collecting data to identify oral health issues and needs, which is essential for planning appropriate interventions.

Question 5

Which type of sealant is more commonly used in the public health setting?&#10;A) Filled photopolymerized sealants&#10;B) Unfilled autopolymerized sealants

Accepted Answer

Unfilled autopolymerized sealants are more commonly used in public health settings because they are easier to apply, do not require a curing light, and are cost-effective for large-scale applications.
