  • Title: Effect of provisional luting agents on polyvinyl siloxane impression material.
    Author: Jones RH, Cook GS, Moon MG.
    Journal: J Prosthet Dent; 1996 Apr; 75(4):360-3. PubMed ID: 8642519.
    Abstract:
    Eugenol-containing cements have been traditionally selected for seating provisional restorations, but incomplete polymerization of polyvinyl siloxane impression materials has been attributed to these cements. This study clinically evaluated the inhibitory effect on polymerization of a specific polyvinyl siloxane impression material with five luting agents used for provisional restorations. Three of these luting agents contained eugenol, whereas two interim cements did not contain eugenol. A total of 60 human posterior teeth were prepared for complete crowns, fitted for provisional crowns, and cemented with interim luting agents. After 2.5 weeks the provisional crowns were removed, the cement on tooth preparations was removed with an explorer, and impressions were made. The results revealed that none of the luting agents in this investigation had an inhibitory effect on polymerization of polyvinyl siloxane impression materials.
