What is noticeable when using Ca(OH)2 during pulpotomy?

• A. Induces liquefaction necrosis
• B. Increases pulpal blood flow
• C. Decreases mineralization
• D. Boosts inflammation

Answer: (A)

When using calcium hydroxide (Ca(OH)2) in a pulpotomy procedure, the notable effect is the induction of liquefaction necrosis. Calcium hydroxide has a high pH, which creates an alkaline environment that facilitates the dissolution of necrotic tissue. This property is advantageous in pulpotomy because it helps remove infected or necrotic pulp tissue while preserving the vital portions of the pulp. The liquefaction necrosis is a result of the alkaline nature of Ca(OH)2 leading to cell death in undesirable tissue areas.

The treatment also promotes some degree of healing by allowing the vital pulp to form a new layer of dentin when used appropriately. While the other options involve aspects of pulpal response, they do not directly relate to the distinct reactions of liquefaction necrosis associated with calcium hydroxide use during pulpotomy procedures.
