Which item is used as a matrix option that is transparent to show esthetics?

• A. DG16 Endodontic probe
• B. Clear matrix
• C. Crown remover
• D. Alginate

Answer: (B)

Using a transparent matrix lets you see and control esthetics while shaping and curing a restorative composite. A clear matrix provides the contour you need for the proximal surface while staying visually unobtrusive, so you can observe shade, contact with the adjacent tooth, and marginal integrity as you place and cure the material. Its transparency also allows light to pass through, helping ensure proper polymerization of the composite near the margins.

The other items serve different dental roles: an endodontic probe is used to locate and explore canals, a crown remover is used to take a crown off, and alginate is an impression material for making models—not a matrix for esthetic layering.
