Correct answer: C — Pulpotomy with MTA or ferric sulfate

A pulpotomy is indicated for a primary molar with a vital (but exposed) pulp, no signs of irreversible pulpitis (spontaneous pain, swelling), no internal/pathological root resorption, and adequate root length. The coronal pulp is amputated and a medicament (MTA, ferric sulfate, or formocresol) is placed over the radicular pulp stumps. MTA (mineral trioxide aggregate) is increasingly preferred due to its biocompatibility and superior outcomes. A stainless-steel crown is the definitive restoration.
