Effect Of Grape Seed Extract On Shear Bond Strength At Resin-Dentin Interface.
Pak Oral Dental J Jan ;37(1):152-7.

This study was done to determine the effect of experimental primer containing collagen cross linker in improving the shear bond strength of tooth coloured resin restorations. Mid coronal dentin of 40 extracted human teeth was achieved and conditioned with 10% phosphoric acid. After thorough rinsing and drying, teeth were randomly divided into two groups. Teeth in experimental group were treated with surface application of 6.5% Proanthocyanidin primer. Surfaces of all teeth were treated with bonding agent (Adper single bond 2, 3M ESPE fifth generation etch and rinse system) and restored with composite resin. Restored teeth were stored in distilled water for 24 hours followed by shear bond strength test. Adhesive, cohesive and mixed failures were identified. Data was statistically analyzed using t test and Chi square test. Primer B (containing Proanthocyanidin cross linker) significantly increased shear bond strength and resin penetration at resin-dentin interface. In the light of results of current study, Proanthocyanidin seem to be a promising cross linker that can improve the quality and durability of tooth coloured resin restorations.
