title: Marginal leakage of cast gold crowns luted with an adhesive resin cement.
abstract: The microleakage of cast gold complete crowns cemented with Panavia EX cement was evaluated and compared with those luted with a standard zinc phosphate cement. The effect of water immersion of specimens for 30 and 90 days was also investigated. The finding of this study indicated that crowns cemented with Panavia EX cement exhibited substantially less marginal leakage than those cemented with zinc phosphate cement. No significant difference in marginal leakage was observed between 30-day and 90-day water immersion of crowns cemented with Panavia EX cement.
