Enamel Rods


  • An enamel rod is the basic unit of tooth enamel. 
  • Measuring 4 μm wide to 8 μm high, 
  • An enamel rod is a tightly packed, highly organized mass of hydroxyapatite crystals
  • It provides rigidity to the rods and strengthens the enamel.
  • Enamel rods normally have a clear crystalline structure
  • Light can pass through rods
  • Many rods have a fish scale appearance
  • Shape: Hexagonal
  • Pattern: Keyhole or paddle-shaped prism pattern


Number: 

  • 5 million= mandibular lower incisor to
  • 12 million= maxillary first molar

The direction of rods:

  • Rods are rarely straight, they follow a wavy course from dentin to the enamel surface
  • Generally, they are oriented at the right angles to Dentin surface 
  • Horizontal direction in the cervical and central part of the Crown
  • Oblique to vertical direction in the incisal regions
Striations: 

  • Rods are built up of segments separated by Dark Line in a rhythmic manner
  • Visible by the action of mild acids
  • Striations are uniform of 4 centimetre
