The Investigation of the Marginal Microleakage of Ceramic Veneer Crowns with Different Finish Lines

Objective: This study aimed to evaluate the microleakage of lithium disilicate and zirconium dioxide all ceramic crowns. Materials and Methods: A total of 80 premolar teeth with two different marginal finish lines were divided into 2 groups to produce zirconia and lithium disilicate crowns. The crowns were cemented by two different cements (n=10). Samples were stained with 0.5% basic fuchsin solution and the dye penetration was scored. Statistical comparisons were made using two-way ANOVA and two-sample t-test. Results: There were no statistically significant differences in preparation types (p>0.05). However, ceramic systems and cement types for the microleakage test Conclusion: The use of self-adhesive cement is recommended for lithium disilicate restoration to minimize marginal microleakage.
