Abstract

Objective: To compare the marginal microleakage of ceramic inlays with direct composite in class 2 restorations. In addition, the study evaluated the effect of dental tissues (dentin and enamel) on microleakage.

Materials and Methods: Standard Class II MOD cavities were prepared in 20 noncarious human upper molars, with cervical margin in enamel (mesial) or dentin (distal). The specimens were randomly divided into two groups (n=10). The first group was restored with direct composite (Tetric N-Ceram) which filled incrementally with 2 mm layers after preparing the cavities by etching and bond application. The second group was restored with Empress 2 inlays which were previously made in the laboratory by luting them with a dual curing resin cement (Variolink). After 24 hours of storage in distilled water, teeth were submitted to thermocycling. Then the teeth were coated with nail varnish except for the restoration and 1 mm around them, and immersed in 2% aqueous solution of methylene blue for 12 hours. Teeth were sectioned longitudinally and leakage scores were evaluated using a microscope at 40x magnification.

Results: Data were subjected to nonparametric statistical analysis (Mann-Whitney and Wilcoxon) at the 0.05 level of significance. There was no difference in microleakage between ceramic and direct composite restorations in both of enamel and dentine. In composite, the microleakage occurred in dentin was greater than enamel, whereas this difference in the ceramic restorations between enamel and dentin was not observed.
