Zonalin powder:

Zonalin is an accelerated modified zinc oxide eugenol cement that complies with ISO 3107. Mix zonalin powder and zonalin liquid together to form an economical temporary restoration, base or cement for crowns and bridges. Inlays, orthodontic bands and braces. The mixture is also used for cavity linings under amalgam and silicate restorations, for pulp capping (to protect the pulp from thermal change and acid irritation of the cement) and as a temporary seal for medical dressings. Do not use as a base for composite restorations.
