Histology of Dentin - What is Intertubular Dentin?
An introduction to Dentin
The dentin is a hard tissue that forms the bulk of the tooth.
The dentin is similar to bone but is slightly harder, although softer than enamel.
The dentin has numerous dentinal tubules that run across its length.
Each dentinal tubule houses the cytoplasmic process of an odontoblast (odontoblastic process).
🤔What is Inter-tubular Dentin?
Forms the main portion of the dentin and is found between the dentinal tubules.
It mainly consists of type I collagen fibrils and is less mineralized than the peritubular (or intratubular) dentin.
It is hypothesized that the area or zone between the peritubular and intertubular dentin in hypomineralized and is called the Sheath of Neuman.
This is thought to mark the outer boundary of the dentinal tubule.
