What is the recommended curing light distance from the composite surface during polymerization to ensure adequate depth of cure?
Answer: As close as possible without touching, within 1-2 mm
Holding the curing light tip within 1-2 mm of the composite surface maximizes light intensity and ensures adequate depth of cure.
A tooth with a proximal carious lesion is being restored. Which cavity preparation classification describes this lesion on a posterior tooth?
Answer: Class II
Class II cavity preparations involve the proximal surfaces (mesial or distal) of posterior teeth (premolars and molars).
When performing a rubber dam application for an amalgam restoration, the rubber dam clamp should be placed:
Answer: One tooth distal to the tooth being restored
Placing the clamp one tooth distal to the operative tooth keeps it out of the working field and provides clear access.
The EFDA is preparing to place a base under a deep amalgam restoration. Which base material has the best pulp-protective (obtundent) properties?
Answer: Calcium hydroxide
Calcium hydroxide stimulates reparative dentin formation and has direct pulp-capping and obtundent properties near the pulp.
During coronal polishing, which type of tooth surface should be polished LAST to prevent cross-contamination?
Answer: Areas adjacent to carious lesions or open margins
Carious or compromised areas are polished last to avoid spreading bacteria or debris to healthy tooth surfaces.
Which radiographic finding would indicate that a cavity preparation for amalgam is of adequate depth?
Answer: The preparation has reached into dentin but does not approach the pulp
Ideal amalgam preparations extend into dentin for mechanical retention without approaching or exposing the pulp.
When sealing a pit and fissure with a self-etch sealant system, the acid etching step is:
Answer: Incorporated into the primer, eliminating a separate etch step
Self-etch sealant systems combine the etching and priming steps into one, simplifying placement and reducing technique sensitivity.
