Why are the pulp horns of deciduous teeth (especially mesial horns) significant compared to permanent teeth?
They are farther from the outer surface.
They are closer to the outer surface.
They are the same distance from the outer surface.

When comparing the mandibular primary second molar (E) to the mandibular first permanent molar (6), what is a key difference?
The primary molar is larger in all dimensions.
The primary molar is smaller in all dimensions.
The primary molar has fewer cusps.
The primary molar has no buccal surface.
Why is modification in cavity depth and extension required when working with primary teeth?
Because primary teeth have thicker enamel and dentin
Because primary teeth have reduced thickness of enamel and dentin
Because primary teeth have more roots
Because primary teeth have larger pulp chambers
How do conical roots of primary anterior teeth benefit dental procedures?
They make teeth harder to extract
They facilitate easy removal
They increase the risk of root fracture
They make cavity preparation more difficult
When restoring primary teeth, what is a key concept to remember about the occlusal table?
It is wider than permanent teeth
It is narrower, so the cavity width should be reduced
It is the same as permanent teeth
It does not affect cavity preparation
