What is a key characteristic of zinc-oxide-eugenol type 1 when used as a base?

Zinc-oxide-eugenol type 1 is particularly valued in dental procedures for its ability to provide thermal insulation and sedative qualities. This characteristic allows it to effectively protect the pulp of the tooth from temperature changes and mechanical stimuli during and after restorative procedures. Additionally, the eugenol component imparts soothing properties that can help alleviate any sensitivity or discomfort, making it particularly useful for patients with pulp irritation or inflammation.

While adhesion is a consideration in various dental materials, zinc-oxide-eugenol type 1 is not primarily known for excellent adhesion compared to other materials. It also has limitations regarding the types of restorations under which it can be used; for example, it can be adversely affected by moisture and should not be used under composite resin restorations due to its potential to interfere with the bonding process. The aspect of not irritating the pulp is somewhat accurate, as it is designed to be less irritating than some alternatives, but it does not fully encapsulate the material's primary benefits like thermal insulation and sedative qualities do.
