Dentinal tubules
Dentinal Tubules
Dentinal tubules (pronunciation: den-ti-nal too-bules) are microscopic canals found in dentin, the hard tissue that lies beneath the enamel and cementum in teeth.
Etymology
The term "dentinal tubules" is derived from the Latin word "dentin" meaning tooth, and the Latin word "tubulus" meaning small tube.
Description
Dentinal tubules extend from the pulp cavity to the exterior of the dentin. They are filled with a fluid substance and contain odontoblast processes. The tubules play a crucial role in the sensitivity of teeth, as they allow stimuli to reach the nerve endings in the pulp.
