In the gingival third of primary teeth, enamel rods slope __________.

Occlusally
Cervically
Horizontally
Vertically

The correct answer is: Occlusally

In the gingival third of primary teeth, enamel rods slope occlusally due to the curvature of the tooth's surface. This allows for better resistance to wear and tear, as well as improved structural strength. Option B, cervically, is incorrect because enamel rods do not slope in this direction. Option C, horizontally, is also incorrect because this would result in a weaker structure. Option D, vertically, is incorrect because this would not provide adequate protection for the tooth's surface.
