Which sign is most characteristic of pulp exposure during caries removal?

When the pulp is exposed during caries removal, the hallmark is immediate, brisk bleeding from the pulp tissue as soon as the chamber is breached. The pulp is highly vascular, so direct exposure commonly produces bright red bleeding, sometimes with a pulsatile flow. The other signs don’t fit this acute event: a gradual dull ache points to pulpal inflammation but not to direct exposure; cold sensitivity without lingering pain can occur with dentin exposure or reversible pulpitis but isn’t specific to a direct pulp exposure; swelling after tooth eruption relates to eruption or periapical processes rather than an acute exposure during caries removal.
