Which material is known for its soothing properties when applied to pulp?

IRM, or Intermediate Restorative Material, is known for its soothing properties when applied to pulp. This is primarily due to its formulation, which includes eugenol, a compound derived from clove oil that has analgesic and sedative effects on the dental pulp. When used as a temporary or intermediate restoration in dental procedures, IRM provides relief from thermal and chemical stimuli and can aid in reducing discomfort during the healing process.

In contrast, amalgam, composite resin, and ceramic materials do not possess the same soothing characteristics. While they are effective for restorative purposes, they primarily focus on strength, durability, and aesthetics rather than providing relief to the pulp. This makes IRM particularly valuable in situations where managing pulp sensitivity is crucial, such as after a cavity has been excavated and before more definitive treatment can be performed.
