What is a typical symptom of irreversible pulpitis?

• A. Quick response to cold stimulus
• B. Spontaneous pain
• C. Pain only when chewing
• D. Asymptomatic response to EPT

Answer: (B)

Spontaneous pain is a hallmark symptom of irreversible pulpitis. This condition arises when the dental pulp becomes inflamed and is unable to heal or return to a healthy state. The pain often occurs without provocation, meaning it can arise unexpectedly and may happen at any time, not just in response to stimuli such as heat or cold. This spontaneous pain may be severe and persistent, leading patients to seek dental care urgently.

In contrast, conditions with reversible pulpitis often elicit pain that correlates closely with specific stimuli, such as cold or heat, and typically resolves once the stimulus is removed. Thus, the presence of spontaneous pain is a strong indicator of irreversible pulpitis rather than a reversible condition.
