3M Scotchbond Universal Etching Gel
3M Scotchbond Universal Etchant is an etching gel used with Scotchbond Universal Adhesive to prepare enamel and dentin surfaces before bonding.
The 3M Scotchbond Universal Etchant Etching Gel is an accessory product formulated for use alongside 3M Scotchbond Universal Adhesive, supporting a total-etch or selective-etch bonding technique where the enamel, and in some protocols the dentin, is etched with phosphoric acid gel before the adhesive is applied.
Etching roughens the tooth surface at a microscopic level, increasing the surface area available for the adhesive to grip and improving the resulting bond strength compared with bonding to an unetched surface. Being formulated specifically as a companion product to the Scotchbond Universal Adhesive system, it is intended to complement that adhesive's chemistry rather than being marketed as a standalone universal etchant for any adhesive brand.
Dentists who use a total-etch or selective-etch protocol with Scotchbond Universal Adhesive apply this gel as a routine preparatory step before bonding composite restorations or cementing indirect restorations. General dentists use etching gels like this one for the majority of direct composite restorations that call for enamel etching.
Dental practices across the UAE and GCC using the Scotchbond Universal system commonly keep this etchant in stock alongside the adhesive.
