TOOTH PULP P.2

REVERSIBLE PULPITIS

Sharp, transient, localized pain = A-δ activation

IRREVERSIBLE PULPITIS

Dull, lingering, radiating pain = C-fibre activation

A-DELTA FIBERS

Cold and electric tests primarily stimulate

HYPOXIA

In advanced pulpitis, A-6 fibres are lost due to?

FUNCTIONAL

While C-fibers remain?

A-DELTA FIBERS

Dentin hypersensitivity is mainly due to exposed tubules activating what fiber?

HYPERALGESIA

C-fibre activity increases during inflammation due to sprouting and neuropeptide release, causing?

A-FIBERS

Which type of nerve fiber in the dental pulp is responsible for sharp, quick pain?

C-FIBERS

What type of nerve fiber is responsible for dull, lingering pain in the tooth?

K

This is an important marker for interdentinal afferents andbis usually associated with cutaneous nociceptors, which are pain-sensing receptors on the skin.

Bradykinin, Histamine, Capsaicin

What are the inflammatory mediators for C-fibers?

Minimal

How does the sensitivity of A-beta fibers in the dentin change based on the state of dentinal tubules?
