What fibers carry dentinal pain?

B fibers
C fibers
A delta
A beta

The correct answer is: A delta

Dentinal pain is carried by A delta fibers, not B fibers, C fibers, or A beta fibers. A delta fibers are a type of sensory nerve fiber that is responsible for transmitting fast and sharp pain signals from the teeth to the brain. B fibers carry slow pain signals, so they are not responsible for dentinal pain. C fibers carry dull, aching pain signals, so they are also not responsible for dentinal pain. A beta fibers transmit touch and pressure sensations, so they are not involved in dentinal pain either. The only correct answer is C A delta fibers.
