Name the materials used for pulpotomy in primary teeth, and indicate which is favored today for biocompatibility and sealing.

The key idea is how the pulpotomy medicament affects the pulp’s healing and the seal at the margins. In primary teeth, pulpotomy aims to remove the diseased coronal pulp while keeping the radicular pulp viable, so the material used must be biocompatible with pulp tissue and provide a durable seal against bacteria. Historically, several medicaments have been used for pulpotomy: formocresol, ferric sulfate, and calcium hydroxide. Formocresol was common because of its devitalizing action on the remaining pulp, but concerns about toxicity and potential adverse systemic effects have reduced its use. Ferric sulfate serves mainly as a hemostatic agent and is relatively biocompatible, though its pulp-healing potential isn’t as robust as newer materials. Calcium hydroxide was favored for its favorable pulp response and dentin formation, but in primary teeth it often shows unreliable long-term sealing and higher failure rates due to tunnel defects and internal resorption. Today, materials like mineral trioxide aggregate (MTA) and biodentine are favored for biocompatibility and sealing. They are bioactive, promote treated dentin bridge formation, and provide a superior seal at the tooth-restoration margins, which reduces microleakage and enhances long-term success. They outperform the older options in preserving pulp vitality and stimulating healing, making them the preferred choices for pulpotomy in contemporary pediatric practice.
