About temporary cements
Provisional cementation means cementing a restoration with a luting agent whose retention is deliberately weak, so that the restoration can be removed later as planned. A final restoration is sometimes cemented temporarily too, which gives the patient a chance to judge its appearance and function first. These cements have weaker physical properties and a greater film thickness than the cements used permanently. The FDA classes zinc oxide-eugenol as a Class I device and dental cement other than zinc oxide-eugenol as Class II, both intended among other things to affix a temporary filling or a crown (21 CFR 872.3275).
A provisional cement holds a provisional restoration in place and protects the dental pulp while it is there. The shelf holds both the eugenol cements and the eugenol-free ones, as automix syringes and as powder and liquid.
Eugenol and eugenol-free
Zinc oxide-eugenol cement comes from mixing zinc oxide with eugenol, the oil of cloves, and is dispensed as a powder and liquid or sometimes as two pastes. The oil component is being reduced because it can affect the curing of the long-term cement that follows and reduce its bond strength.
What to look at when choosing a temporary cement
A review lists the qualities asked of a provisional cement: enough strength to retain the restoration for a short period, easy removal and cleaning from both tooth and restoration, and no effect on the adhesion of the long-term cement.
Some temporary cements contain fluoride, and a review notes that adding fluoride slightly increases the solubility of the cement.
Residue: a review notes that provisional cement left on the tooth is thoroughly removed before the final cement is applied. Zinc oxide-eugenol is also listed by the FDA as a material applied to a tooth to protect the tooth pulp.
