dentinal fibers

(redirected from odontoblastic processes)

den·ti·nal fi·bers

, dental fibers
1. the processes of the pulpal cells, the odontoblasts, which extend in radial fashion through the dentin toward the dentoenamel junction and are contained within the dentinal tubules; Synonym(s): odontoblastic processes, Tomes fibers
2. the intertubular fine collagenous fibers that with the dentinal ground substance infiltrated with calcium salts constitute the dentinal matrix.

Tomes,

Sir John, English dentist and anatomist, 1815-1895.
Tomes fibers - the processes of the pulpal cells which are contained within the dentinal tubules. Synonym(s): dentinal fibers
Tomes granular layer - a thin layer of dentin adjacent to the cementum.

dentinal

pertaining to dentin.

dentinal fibers
fibers contained in predentin but displaced by dentin as it is deposited, the fibers leaving apical processes of odontocytes behind, contained in dentinal tubules through which nerves also pass; called also odontoblastic processes.

Mechanical instrumentation of root canals produces a smear layer comprising organic and inorganic substances, such as dentin particles, necrotic debris, microorganisms, and odontoblastic processes [2].
According to this theory, odontoblastic processes are exposed on the dentine surface and can be excited by a variety of chemical and mechanical stimuli.
To date no neurotransmitters have been found to be produced or released by odontoblastic processes.
Additionally, the odontoblasts, which are the dentin-producing cells, are located near the pulp with the odontoblastic processes being restricted to the inner one-third of the dentinal tubules.
