Correct answer: A — It can increase monomer conversion and improve control of anatomy, finishing and marginal adaptation.
Explanation lettering: D = shown as B · B = shown as C · C = shown as D
A is correct. Additional extraoral curing or industrial processing can increase monomer conversion and allows anatomy, marginal adaptation and surface finishing to be controlled outside the mouth. Most bulk polymerisation also occurs before bonding, although the resin luting layer still undergoes some shrinkage. Indirect restorations are generally more costly and involve additional fabrication and cementation stages, so B is incorrect. They require adhesive cementation and effective isolation, excluding C. Conventional indirect composites do not provide the sustained fluoride release associated with glass-ionomer materials, excluding D. Polymerisation shrinkage is reduced intraorally rather than abolished because the resin cement must polymerise after seating, excluding E.
