Regarding bioceramic materials for pulp capping, which of the following is NOT an advantage?

  1. Prevents propagation of secondary caries
  2. Acidic pH
  3. Biocompatible and promotes dentin bridge formation
  4. Can be applied directly on the pulp
Show answer and explanation

Correct answer: B. Acidic pH

  • A. ❌ Bioceramics DO help prevent secondary caries through their antimicrobial alkaline environment — this IS an advantage.
  • B. ✅ Correct (exception). Bioceramics have an ALKALINE pH (approximately 12.8), NOT acidic. This is the property they do NOT have — acidic pH would harm the pulp.
  • C. ❌ Bioceramics ARE biocompatible and DO promote dentin bridge formation — this IS an advantage.
  • D. ❌ Bioceramics CAN be applied directly on the pulp — this IS a feature.
