Home Dentistry Articles Interrod enamel
Interrod enamel is histologically identified
on microscopic views of tooth enamel. Because interrod enamel
is located around enamel rods, the areas of interrod enamel
enhances the "key-hole" appearance of enamel rods
by acting as its border. The location where the two areas of
enamel meet is known as the rod sheath.
All tooth enamel, including interrod enamel
and enamel rods, is made by ameloblasts. However, interrod enamel
is formed slightly sooner than enamel rods.
Interrod enamel has the same composition as
enamel rods. A distinction is made between the two because they
differ in the direction of their crystalline patterns.
