Sample item

Why is matrix band placement used during a proximal composite restoration?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Recreate contour and contact with adjacent tooth

A matrix band provides a temporary wall that helps shape the proximal surface and establish a contact point while restorative material sets.

Option by option

  • A. Assess occlusal nerve supply

    Nerve supply is not assessed here.

  • B. Measure periodontal pocket depth

    Pocket depth needs a periodontal probe.

  • C. Sterilize cavity preparation

    Sterility is not achieved by the band.

  • D. Recreate contour and contact with adjacent tooth (correct)

    Correct: matrix forms proper proximal anatomy.
