Zinc oxide eugenol is a:

Zinc oxide eugenol is used as a temporary cement because it provides a mild, soothing effect on the tooth while still allowing the provisional restoration to be easily removed later. The eugenol component helps calm the dental pulp, which is useful when a tooth needs a temporary crown, inlay, onlay, or bridge during evaluation or treatment planning. Its cement has lower strength and is not meant for long-term retention, so it holds the provisional restoration in place without creating a permanent bond. This material isn’t for permanent cementation, because eugenol can interfere with the bonding and setting of resin-based cements and other permanent luting agents. It’s also not an impression material, which is used to capture the tooth’s form for fabrication.
