During an endodontic-access restoration, why is a dual-cure composite used?
Show answer and explanation
Correct answer: B. It allows polymerization at depths the curing light cannot reach
- A. Incorrect – an adhesive system is still required.
- B. Correct – the chemical-cure component sets the deep increments (e.g., inside the access/pulp chamber) where light penetration is inadequate.
- C. Incorrect – 'quality' is not the rationale; depth of cure is.
- D. Incorrect. Dual-cure material still benefits from light activation where light reaches; its advantage is the additional chemical (self-cure) reaction at depth, not elimination of light curing.
