One-Step is one of the most versatile and convenient single bottle total-etch adhesive that bonds to multiple substrates including metal. Its unique chemistry makes it compatible with light-, dual- and self-cured materials without the need for an activator and its low film thickness (less than 10 microns) allows it to be used in direct or indirect procedures.
One-Step and One-Step Plus are light-cured, single component adhesives that, unlike others, bond to a multitude of dental substrates, including self-cured and dual-cured materials. One-Step, the clinically proven unfilled adhesives is also available in a filled version, One-Step Plus. The One-Step and One-Step Plus patented* formulations utilize some of the same patented chemistry found in All-Bond 2®.

Frequently Asked Questions
The term "total-etch" is used for simultaneous etching of enamel and dentin with phosphoric acid to remove the smear layer and to obtain micro-porosities for the integration of the bonding agent. The etching should start with enamel and then move to dentin. BISCO recommends a 15 second etch as a general guideline. Excessive etching of dentin may cause hypersensitivity and incomplete hybrid layers.
It is critical to keep the prepared dentin moist. Wet (moist) bonding is desirable because it prevents exposed collagen fibers from collapsing. For total hybridization and optimal bond strength, these exposed collagen fibers must be infiltrated and saturated by the primer/adhesive. The saturation is confirmed clinically by observing a glossy surface of primer/adhesive after thorough evaporation of the solvent. Over dried collagen leads to the formation of a dense amorphous layer that may impede infiltration of the primer/adhesive solution into the intertubular dentin and results in incomplete hybridization.
Air drying is not recommended. Air drying may collapse collagen fibrils while incorporating air into the dentinal tubules with possible cause of postoperative sensitivity. High volume suction removes pooled water and allows for collagen fibrils to remain sufficiently hydrated, facilitating primer infiltration. Alternatively, an absorbent pellet may be used to blot pooled water from the dentin.
