Which region has tubules described as 'small and few per area'?

Explanation:
Tubes in dentin vary in quantity and size depending on how close you are to the pulp. Closer to the pulp, they’re numerous and relatively larger; as you move toward the dentinoenamel junction, they become fewer and smaller. Enamel itself doesn’t have dentin tubules at all, so regions within enamel aren’t described by dentin tubule density. Therefore, describing tubules as small and few per area fits best for the region near the dentinoenamel junction.
