Question 1

Which of the following steps should be performed IMMEDIATELY before applying the sealant material to the tooth?

Question 2

An air-water syringe tip used during sealant placement must be verified to be free of:

Compressor oil or water from the air-water syringe can contaminate the etched enamel surface and compromise the sealant bond.

Question 3

For a partially erupted molar where full isolation is difficult, which sealant material is MOST appropriate?

Answer

Sealant should be gently flowed into the pits and fissures using capillary action to prevent air bubble entrapment that can create voids.
