Abstract
Purpose: The purpose of this study was to evaluate the effect of three different base materials (GIC, Chemfill rock, and SDR,) on microleakage, fracture resistance, and color stability of two ceramic inlays (E max and Vita suprinity).
Materials and methods: Sixty extracted premolars were prepared for Class II inlay MOD.
For microleakage test thirty teeth divided into three groups (n=10); group (A): restored with (GIC). Group (B): restored with Chemfill rock. Group (C): restored with SDR. After thermocycling the microleakage was evaluated by scores. For evaluation of fracture resistance and color stability, the remaining thirty teeth were divided into two groups(n=15) Group (1): The teeth restored with Emax inlay. Group (2): restored with Vita Suprinity inlay. Each group was subdivided into three subgroups(n=5); Subgroup (I): based with (GIC). Subgroup (II): based with Chemfill Rock. Subgroup (III): based with SDR.
Results: For microleakage test; SDR base had stage zero leakage, leakage was higher in GIC base. For fracture resistance test; there is statistically significant high mean of fracture resistance in SDR base. On the other hand there is no statistically significant difference as fracture resistance between E-max, and Vita Suprinity restoration. For color stability test; there is statistically significant difference high mean of color difference in SDR base with p-value <0.05. On the other hand there is no statistically significant difference between E-max, and Vita Suprinity restoration.
Conclusion: SDR is the best base regarding microleakage, color stability and fracture resistance. While there is no significant difference between Emax and Vita Suprinity restorations.in color stability and fracture resistance.
