Where should an indirect pulp cap be placed?

  1. Place the liner in the prepared (deepest dentin) area
  2. Apply etch before placing the liner
  3. Place MTA over the prepared area
Show answer and explanation

Correct answer: A. Place the liner in the prepared (deepest dentin) area

  • A. Correct. In an indirect pulp cap, a biocompatible liner (e.g., calcium hydroxide/RMGI) is placed on the thin remaining dentin closest to the pulp.
  • B. Etching directly over the deepest dentin/near-exposure before lining is contraindicated (acid insult near pulp).
  • C. MTA is used for DIRECT pulp caps/exposures, not routinely for an indirect cap over intact dentin.
