Latus Etching Gel – 37% Orthophosphoric Acid. Reliability of 37% Orthophosphoric Acid is the key to an ideal restoration

Latus Etching Gel is a high-quality, economical, and effective gel based on 37% orthophosphoric acid, developed for use in all adhesive protocols that require prior etching of enamel and/or dentin (Total-Etch and Selective-Etch techniques). This gel is essential for creating the ideal micro-retention pattern on the enamel and effectively removing the smear layer on the dentin, which ensures deep penetration of adhesive systems and the formation of a strong hybrid layer. The 14 g syringe provides long-lasting and convenient use in clinical practice.

Key Properties and Advantages

• Optimal Concentration (37%): The 37% concentration of orthophosphoric acid is the most scientifically proven and clinically validated concentration for achieving maximum bond strength to enamel and dentin.

• Thixotropic Consistency: The gel has an ideal viscosity: it is easily extruded through the applicator and accurately applied to the surface, but it does not slump from vertical surfaces. This allows for controlled etching margins, especially during selective enamel etching.

• Clear Visualization: Thanks to its bright, contrasting color (usually blue), the gel is easily visualized on the tooth surface, ensuring complete control over exposure time and rinsing quality.

• Effective Rinsing: The formula guarantees fast and complete rinsing with water without residue. This minimizes the risk of residual acid that could interfere with adhesive polymerization.

• Cost-Effectiveness: The large syringe volume (14 g makes this etching gel an economical solution for clinics with a high patient flow.

Indications for Use

Latus Etching Gel is used as a mandatory step in preparation for:

• Direct restorations using 4th and 5th generation adhesives (Total-Etch).

• Enamel etching before using universal adhesives (Selective-Etch).

• Cementation of indirect restorations (veneers, inlays) using adhesive cements.

• Fissure sealing.

• Fixation of braces and orthodontic appliances.

Key Moments of the Etching Protocol

• Enamel: Recommended etching time is 15-30 seconds.

• Dentin: Recommended etching time is 10-15seconds. It is important not to over-etch the dentin.

• Rinsing: Thorough rinsing with plenty of water (minimum 10seconds).

• Moisture Control: After rinsing, the enamel should appear frosty/chalky. Dentin in the Total-Etch technique must remain moist (to prevent collapse of collagen fibers).

Latus Etching Gel is a reliable component for creating the ideal adhesive surface, which is the guarantee of long-term success for any composite restoration.
