Calcium hydroxide cavity liners are bactericidal and also help coagulate which pulpal exudate?

• A. serous exudate of pulp
• B. purulent exudate of pulp
• C. No exudate coagulation
• D. hemorrhagic exudate of pulp

Answer: (D)

Calcium hydroxide works both as a strong antimicrobial at its high pH and as a hemostatic agent that interacts with pulpal tissue. When the pulp is inflamed, the exudate present can be serous, purulent, or hemorrhagic. The alkaline environment of calcium hydroxide denatures proteins in the blood, causing coagulation of hemorrhagic exudate. This coagulation helps form a protective clot at the pulp exposure and provides a favorable environment for reparative dentin formation. Serous or purulent exudates are not coagulated in the same way, so the effect is most evident with hemorrhagic exudate.
