Correct answer: D — Create a firm proximal contact

Explanation lettering: E = shown as A · A = shown as D · D = shown as E

The correct answer is A. An open proximal contact permits food to wedge between teeth; the restoration should therefore recreate a firm, appropriately positioned proximal contact. This addresses the stated cause of the patient’s food packing. A broad embrasure should not be managed by making it wider, as in B, because this does not restore contact and may worsen food stagnation. An occlusal fissure sealant (C) has no effect on proximal contact anatomy. Buccal contouring (D) changes the wrong surface and cannot close an interproximal contact. Extraction (E) is unjustifiably destructive for a local restorative contour problem. In contrast, food impaction with a tight contact may require assessment of occlusal morphology, but this stem explicitly describes an open contact.
