SHERIDAN, WYOMING – May 2, 2025 – BISCO, a leader in dental adhesive technology, has reaffirmed its commitment to clinical excellence with its tailored line of etchants: Select HV Etch w/BAC and Uni-Etch w/BAC. Designed to enhance total-etch and selective-etch bonding procedures, these formulations provide dental professionals with optimized viscosity and added antimicrobial benefits for superior adhesion outcomes.
Precision Viscosity for Clinical Control
BISCO’s two phosphoric acid-based etchants are strategically developed to align with evolving clinical preferences. The original Uni-Etch, a 32% semi-gel, offers smooth flow and wide coverage—ideal for traditional total-etch techniques that involve treating both enamel and dentin. In contrast, Select HV Etch, a 35% highly viscous formulation, is purpose-built for the increasingly preferred selective-etch technique, offering precise control and placement limited to enamel.
“It had to be thicker,” noted Dr. Rolando Nuñez, BISCO’s Manager of Clinical Marketing. “Its viscosity helps the placement of etchant on the enamel without the added risk of running into the dentin.”
While each etchant has a distinct consistency, both can be used flexibly across bonding techniques. This dual-approach empowers clinicians to adapt their protocols without compromising reliability or performance.
“You can rest assured that the etchant will accomplish what you need to obtain the best bond possible,” said Dr. Nuñez.
Incorporating BAC for Long-Term Bond Strength
A significant value-add in both BISCO etchants is the inclusion of benzalkonium chloride (BAC)—a multipurpose agent that not only cleanses the tooth surface but also inhibits matrix metalloproteinases (MMPs), enzymes known to degrade the hybrid bonding layer over time. This biochemical safeguard contributes to stronger and more durable adhesive bonds.
As Dr. Todd Snyder, a recognized clinical expert, explains: “Phosphoric acid alone doesn’t eliminate bacteria, so benzalkonium chloride is added to help cleanse the tooth for the best possible bond. That’s a huge advantage.”
Responding to Evolving Clinical Techniques
Phosphoric acid remains a cornerstone in modern adhesive dentistry. As clinical approaches shift from total-etch to more conservative selective-etch protocols, BISCO’s dual-product offering meets the needs of both schools of practice. Whether a practitioner opts for broad dentin involvement or enamel-focused etching, the company’s solutions provide adaptability and consistency.
This versatility reflects a deep understanding of dental practice realities. As Dr. Nuñez emphasizes, “Etching with phosphoric acid is half of the bonding procedure. Using the best product available can make a difference.”
Driving Better Clinical Outcomes Through Innovation
With continued innovation in dental materials, BISCO remains focused on delivering high-performance products that enhance operational efficiency and patient outcomes. By offering etchants with precise viscosities and enhanced surface treatment capabilities, the company enables clinicians to practice with confidence and control.
