Interglobular Dentin

  • Sometimes mineralisation of Dentin begins in small globular areas that fail to fuse into the homogeneous mass. 
  • It results in Zones of Hypomineralisation between globules. 
  • Most commonly found in Circumpulpal Dentin which is present below the Mantle Dentin. 

In other words, in poorly formed teeth, due to deficiency of vitamin D or exposure to fluoride, it leads to defect in mineralization i.e. loss of globular dentin.

Note: Defect is not because of improper matrix formation.

Thought Question: Dentinal tubules pass uninterruptedly through Globular Dentin. Why? Comment your answers!
