What is the pulpal diagnosis of a tooth that has caries and responds with lingering pain to cold?
Rufina [12.5K]

Reversible pulpitis is the pulpal diagnosis of a tooth that has caries and responds with lingering pain to cold.

When a stimulus is provided to the tooth in reversible pulpitis, typically something cold or sweet, pain is felt. Within one to two seconds of the stimulus being removed, the pain stops. When the stimulus (often heat, but less frequently cold) is withdrawn, pain either arises spontaneously or persists for minutes, which is irreversible pulpitis.

Dental pulp and root damage can result from tooth decay that has penetrated deeply into the tooth. oral surgery. After receiving a filling, crown, or other dental procedure, pulpitis can occasionally occur. When the initial dental procedure is fixed, this may result in reversible pulpitis that can be treated.
