When no calcium hydroxide or MTA is available, which material is the best alternative for pulp capping?
Show answer and explanation
Correct answer: D. Bioceramic cements
- A. ❌ Silicate cements are not recommended for direct pulp capping — they can be irritating to the pulp.
- B. ❌ Zinc oxide eugenol can be cytotoxic to the pulp in direct contact and is not recommended for direct pulp capping.
- C. ❌ Glass ionomer cement is not indicated for direct pulp capping due to pulp irritation potential.
- D. ✅ Correct. Bioceramic cements (e.g., Biodentine, TotalFill BC, BioC Repair) are the best alternative when CaOH₂ or MTA are unavailable. They have an alkaline pH (~12.8), are biocompatible, promote dentin bridge formation, and have antimicrobial properties.
