Pulpitis is an inflammation of the dental pulp, which is the soft tissue inside the tooth that contains nerves and blood vessels. When this tissue becomes inflamed, it can cause significant pain. The type of fibers that carry this pain are known as C fibers, which are unmyelinated nerves responsible for carrying slow, dull, and chronic pain signals.

A beta fibers are responsible for carrying fast and sharp pain signals and are not typically involved in pulpitis pain.

Similarly, A gamma fibers are involved in muscle function and do not play a role in carrying pain signals.

B fibers, also known as myelinated fibers, are responsible for carrying information related to touch, pressure, and vibration, but not specific to pulpitis.

In conclusion, the correct answer is D C fibers. These fibers are responsible for carrying the slow, dull, and chronic pain signals associated with pulpitis.
