Which material is used in a pulpotomy procedure due to its therapeutic effects?

1. Calcium hydroxide

2. Formocresol

3. Composite resin

4. Glass ionomer

The correct answer is: Calcium hydroxide

In a pulpotomy procedure, calcium hydroxide is widely recognized for its therapeutic effects, making it an ideal choice. This material is known for its ability to promote healing and dentin formation, acting as a biocompatible agent. When applied to the exposed pulp, calcium hydroxide facilitates the formation of a protective barrier of secondary dentin, helps maintain the vitality of the remaining pulp tissue, and can stimulate the pulp's natural healing processes. This is particularly important in pediatric dentistry, where preserving the vitality of the tooth is often a primary goal during pulp treatment. The other materials listed do have their applications in dental procedures but do not possess the same therapeutic effects specifically required for a pulpotomy. Formocresol, although used in pulpotomies, is more controversial due to its potential cytotoxic effects and concern over long-term impacts on the pulp tissue. Composite resin is generally used for restorations rather than pulp therapies. Glass ionomer cement may be utilized for temporary sealing or as a base material but lacks the specific healing properties that make calcium hydroxide a preferred option in pulpotomy procedures.
