Tomes fiber
The Tomes fiber (named after the English oral surgeon John Tomes , 1815–1895) is the cell extension of an odontoblast ( dentine builder) that is located in the dentinal tubules .
The Tomes fibers begin as a thin cytoplasmic process of the odontoblasts, the perikaryon (cell body) of which is located on the border with the tooth pulp . The Tomes fibers extend to the dentin-enamel boundary and contact the preformative membrane there . With the fibers, non-medullary nerve fibers pull along, which cause toothache caused by caries . This has moved away from the earlier assumption that forwarded fluid movements in the dentinal tubules are responsible.
The Tomes- fibers are not to be confused with the Tomes- projections of ameloblasts .
