title: Microleakage of two new dentin adhesives.
abstract: This in vitro study evaluated the microleakage of Class V resin composite restorations bonded with All-Bond 2 Universal Dental Adhesive and Scotchbond Multi-Purpose Dental Adhesive System. For comparison, other restorations were placed with Scotchbond 2 Light Cure Dental Adhesive or with no bonding agent. Class V cavities were restored with either one or two increments of resin composite to determine whether the restorative method affected microleakage. A silver nitrate staining technique was used to detect marginal leakage. There was no leakage at the etched enamel margins in any treatment group. All-Bond 2 had significantly less leakage at the gingival margins than the other two dentin adhesives. Scotchbond Multi-Purpose had less leakage than Scotchbond 2, which was not statistically different from the control (no bonding agent). Incremental filling significantly reduced leakage only in the control group.
