Correct answer: E — MTA (mineral trioxide aggregate)

MTA (mineral trioxide aggregate) is currently considered the most biocompatible direct pulp capping material. It has superior outcomes compared to calcium hydroxide in terms of bridge formation quality, reduced inflammation, and long-term pulp vitality. MTA has an alkaline pH (~12.5), releases calcium ions promoting hard tissue formation, has excellent sealing ability, and is biocompatible. Calcium hydroxide has been the traditional standard but has limitations including tunnel defects in the dentin bridge and dissolution over time.
