Effect of Eugenol Exposure Time and Post-removal Delay on the Bond Strength of a Self-etching Adhesive to Dentin
Clinical Relevance The presence of a provisional restoration containing eugenol for one week or longer does not interfere with the bond strength of self-etching adhesives to dentin. If a eugenol-based provisional restoration remained in place for only 24 hours, a delay of one week re-establishes proper bond strength.
