Continuing Education etched with phosphoric acid. The light-cured products in 4th -generation dual-cured products typically mixing, minimizing the possibility for error.3 -generation systems typically require four steps, including etching, rinsing and drying, primer application, and adhesive application, while 4th necessitate six steps, including etching, rinsing and drying, mixing both components with a catalyst, applying primer, and applying adhesive (Table 2). Examples of light-cured systems include Adper™Scotchbond™Multipurpose Plus (3M ESPE, www.3mespe.com), ALL-BOND 3™(Bisco, www.bisco.com), Bond-It® (Pentron Clinical, www.pentron.com), LuxaBond® Total-Etch (DMG America, www.dmg-america.com), and Optibond FL (Kerr, www.kerrdental.com). Dual-cured system products include Adper Scotchbond Multipurpose Plus, ALL-BOND 3, Bond-It, and LuxaBond Total-Etch. The number of steps and requirements for exact com-ponent measurements of 4th -generation systems can be dif-ficult to perform chairside, increasing the risk for error. This led to the development of 5th -generation dental adhe-sives, characterized by single-bottle bonding agents with no Table 2: Steps for Use of Bonding Agents Etch Unground Etch with Bonding Agent Total-etch, multiple-bottle, light-cured (4th ) Total-etch, multiple-bottle, dual-cured (4th ) Total-etch, single-bottle, light-cured (5th ) Total-etch, single-bottle, dual-cured (5th ) Self-etch, light-cured (6th Type I) Self-etch, dual-cured (6th Type I) Self-etch, light-cured (6th Type II) Self-etch (no mix), light-cured (7th ) Self-etch, dual-cured (7th ) *Both primer and adhesive.

Fifth-generation light-cured systems typically require etching, rinsing and drying, and primer/adhesive applica-tion, while the dual-cured systems necessitate an additional step of mixing with a catalyst (Table 2).3 Light-cured 5th -generation bonding agents include Adper Single Bond Plus (3M ESPE), ONE STEP PLUS (Bisco), and Optibond® Solo Plus (Kerr). Dual-cured 5th -generation bonding agents include Bond-1 (Pentron Clinical), ExciTE® DSC (Ivoclar Vivadent, www.ivoclarvivadent.com), and Prime & Bond® NT™ (DENTSPLY Caulk, www.dentsply.com).
