Which of the following is not a recognized use of zinc oxide and eugenol cement?

Zinc oxide and eugenol cement is widely recognized for several uses in dental practice, including as a luting agent, sedative dressing, and periodontal dressing. However, it is important to clarify that it is not typically recognized as an impression paste.

As a luting cement, zinc oxide and eugenol is used to adhere crowns and other restorations, providing a strong bond. When utilized as a sedative dressing, it offers a soothing effect on sensitive dental tissues due to the eugenol component, which has analgesic properties. Furthermore, as a periodontal dressing, it helps to protect surgical sites and supports tissue healing after periodontal procedures.

The common misconception arises when considering impression materials; these require specific properties such as viscosity and setting behavior that are not characteristics of zinc oxide and eugenol cement. Impression materials are designed to capture precise details of dental structures, while zinc oxide and eugenol do not fulfill these criteria, making it clear why this particular cement is not classified as an impression paste.
