A patient's permanent first molar has a retained primary molar root tip blocking the occlusal fissure. Sealant placement should be:
Answer: Deferred until the dentist evaluates the tooth
Abnormal findings such as retained roots must be evaluated by the dentist before preventive procedures are performed.
Which finishing instrument is used to smooth interproximal composite surfaces after initial carving?
Answer: Finishing strip
Finishing strips allow access to interproximal composite surfaces for smoothing and contouring after initial carving.
The Caries Management by Risk Assessment (CAMBRA) protocol guides the EFDA to recommend fluoride varnish frequency based on:
Answer: Patient's caries risk level
CAMBRA categorizes patients as low, moderate, or high risk for caries, with fluoride varnish frequency increasing with higher risk.
When using an amalgamator, which factor most directly affects the consistency and strength of the amalgam mix?
Answer: The trituration time and speed
Trituration time and speed control the degree of amalgamation, directly affecting the working consistency and final strength of the restoration.
During a preventive resin restoration (PRR), after removing carious tissue from a pit, the EFDA places:
Answer: A composite restoration in the carious area sealed with pit and fissure sealant over adjacent pits
A PRR combines a minimal composite restoration in the carious pit with sealant coverage of adjacent sound pits and fissures.
After final polishing of an amalgam restoration, the surface should appear:
Answer: Highly reflective and smooth
A properly polished amalgam restoration has a smooth, reflective surface that reduces plaque retention and corrosion.
Which sealant failure is most commonly caused by inadequate isolation during placement?
Answer: Partial or complete loss of sealant due to salivary contamination
Salivary contamination during etching or sealant placement compromises bonding, leading to premature loss of the sealant.
