| Abstract | ||
| The study aims to evaluate and compare the microleakage of three different lutingmaterials. The materials compared areZinc phosphatecement, Variolink II Refilland Glass ionomer resin cement.Eighteen recently extracted caries-free wisdom teeth were used . The teeth were cleaned then stored in distilled water until use. The molars were assigned randomly into three groups of 6 teeth of each .Themetal ceramic crowns were constructed by means of an indirect laboratory technique. In group A, the crowns were cemented with a traditional Zinc Phosphate. In group B, the tooth preparations were sealed with VariolinkII Refill. In group C, the tooth preparations were sealed with glass ionomer resin cement prior to cementation with the crowns.The results showed highervalue of microleakage forZinc phosphate cement. While the least value was for the Variolink II . The value for Glass ionomer resin cement was low. Statisticallyanalysis revealeddifference between the Zinc phosphate cement ,Variolink II andGlass ionomer resin cement in microleakage. There was no significant difference in microleakage between Variolink II and Glass ionomer resin cement. This may indicated that the degree of microleakage may influenced by the type of theluting system used. | ||
