: 28 third molar teeths were randomly assigned two groups. Class V cavities were prepared on the facial surface of each tooth with coronal margins enamel and apical margins in cementum (dentin) at the cementoenamel junction. The preparations were restored using Clearfil SE Bond and Clearfil S3 Bond that bonded wet dentin (control), or ethanol-prepared dentin, followed by insertion of Filtek Z 250 composite restorations. The teeth (specimens) were thermocycled 1,000 cycles, immersed 0,5% methylene blue dye for 24 hours. The specimen were then sectioned longitudinally, with dye penetration (microleakage) examined using a 40× stereomicroscope. Coronal and apical margins were dye penetration was scored: 0=no penetration; 1=partial dye penetration along the occlusal or gingival wall; 2=dye penetration along the occlusal or gingival wall; 3=dye penetration to along the axial wall. Data were analyzed by Kruskal- Wallis one-way ANOVA.
