Latar belakang: Ketahanan ikatan antara resin komposit dengan dentin merupakan penentu keberhasilan restorasi resin komposit. Tujuan: Menganalisis EBA terhadap kekuatan ikat resin-dentin. Metode: 48 sampel dentin dibagi menjadi 6 kelompok. Kemudian seluruh kelompok di ukur kekuatan ikat gesernya menggunakan UTM. Data dianalisa statistik dengan uji hipotesis Kruskal Wallis yang dilanjutkan dengan uji Mann Whitney. Hasil: Median tertinggi kelompok 3, sedangkan median terendah kelompok 5. Kesimpulan: Ekstrak biji anggur yang diaplikasikan sebelum etsa dapat meningkatkan kekuatan ikat gesek namun tidak dapat menghambat biodegradasinya.ABSTRACT
Background: Resilience of resin-dentin bonding known as one of success composite resin restoration determinants. Aim: To analyze the effect of grape seed extract on resin-dentin shear bond strength. Methods: 48 dentin sample were divided into 6 groups. Shear bond strengths measured using UTM. Statistical analysis was done by Kruskal Wallis test and Mann Whitney test. Results: The highest median value was highest on group 3, and the lowest was group 5. Conclusion: Grape seed extract can improve the shear bond strength but not have effect on reducing the biodegradation. ;Background: Resilience of resin-dentin bonding known as one of success composite resin restoration determinants.
