What is the common result of irreversible pulpitis?

1. Potential for pulp healing

2. Death of pulpal cells

3. Temporary sensitivity

4. Complete regeneration of pulp

The correct answer is: Death of pulpal cells

Irreversible pulpitis is a condition characterized by inflammation of the dental pulp that cannot heal on its own. The key feature of irreversible pulpitis is the significant and often prolonged irritation and damage to the pulpal tissues, usually due to factors such as deep caries, trauma, or extensive dental procedures. As a result of this ongoing inflammation, the cells within the pulp begin to necrose, leading to the death of pulpal cells. This condition differs fundamentally from reversible pulpitis, where the pulp remains vital and capable of healing if the irritant is removed. In irreversible pulpitis, the extent of damage is such that the pulp cannot recover, leading to the necessity for interventions like root canal therapy or, in more severe cases, extraction. Other options, such as pulp healing, temporary sensitivity, and complete regeneration, do not accurately reflect the prognosis for a tooth with irreversible pulpitis since the tissue is already compromised beyond the point of self-healing.
