Using a small round or needle-shaped bur or diamond rotary instrument prior to placement of a dental sealant can allow for inspection for the presence of caries, and
reduce the amount of sealant required to protect fissures and grooves in the tooth.
allow the expanded-functions dental assistant (EFDA) to apply sealant without the dentist being present in the office.
provide for increased retention of the sealant material.
eliminate the need to evaluate the occlusion following placement of sealant.
What is the primary reason that few children are protected by dental sealants?
They are not recommended by the American Dental Association.
They have not been shown to reduce decay significantly.
There is a lack of public awareness.
They are not effective for prevention of pit-and-fissure decay in posterior teeth.
Which statement is correct regarding a properly placed sealant over small initial carious lesions?
The decay will continue to develop under the sealant
Bacteria can survive under a sealant.
The number of bacteria in small carious lesions decreases over time.
The number of bacteria in small carious lesions increases over time.
Which technique is sometimes used before sealant application to open fissures and remove slight decay?
Rubber cup polishing
Bristle-brush polishing
Microabrasion
Scaling
Why are sealants contraindicated in teeth with proximal caries?
Proximal decay will spread to the occlusal surface.
Posterior proximal tooth preparation will usually include the occlusal pits and fissures.
Sealants are placed on smooth surfaces and the proximal area is a smooth surface.
Sealants are placed on smooth surfaces and the proximal area is a rough surface.
