DENTSPLY Caulk’s Prime and Bond Elect™: The Choice for All Clinical Situations

Recently, a third bonding technique has emerged—one that allows for hybridization of the remaining dentin smear layer and includes phosphoric etching of exposed enamel to maximize bond strength and prevent marginal discoloration. The selective-etch technique is designed to harness the positive attributes of both techniques for improved clinical outcomes. Several recent studies found that selective-etch adhesives have increased enamel bonding without postoperative sensitivity.^4,5 A meta-analysis reported by Heintze and Rousson concluded that restorations placed with rubber-dam isolation and enamel-etching technique showed the best overall performance.⁶

Prime and Bond Elect™ from DENTSPLY Caulk is designed as a one-bottle dental adhesive suitable for all three adhesive modes: total-etch, self-etch, and selective-etch. Based on 13 years of proven PENTA (ie, the adhesive resin dipentaerythritol pentaacrylate monophosphate) technology from Prime and Bond® NT™, this new bonding agent provides a unique micromechanical and chemical bond for long-term success.⁷ It is ideal in cases where the preparation is primarily in enamel and total-etch technique is indicated; in mostly dentin preparations where a self-etch technique can be used; and for preparations containing a significant amount of enamel and dentin where a selective-etch technique is advised. Practitioners using Prime and Bond Elect according to the directions need not fear negative sequelae experienced with other products, such as decreased dentin bond strengths, if phosphoric etchant gel unintentionally contacts exposed dentin.
