Clinical Overview
Ultra‑Etch™ is a 35% phosphoric acid gel formulated for total‑etch adhesive procedures on enamel and dentin. Its thixotropic viscosity ensures precise placement without slumping, while its self‑limiting etch depth (~1.9 µm in 15‑20 s) enhances bond durability and minimizes postoperative sensitivity.
Key Benefits
- Self‑limiting etch depth (~1.9 µm): Reduces risk of overetching and ensures adhesive penetration.
- Ideal viscosity: Penetrates fissures via capillary action yet resists migration on vertical surfaces.
- Blue tint enhances visibility: Facilitates accurate placement and confirms complete rinsing.
- Clean rinse-off: Eliminates residue, simplifying workflow and minimizing contamination.
- Complete kit format: Four syringes plus 20 Blue Micro™ tips support multiple operative procedures.
Kit Contents
- 4 × 1.2 mL syringes of 35% Ultra‑Etch phosphoric acid gel
- 20 × Blue Micro™ disposable tips for precision delivery
Application Timing & Etch Protocol
- Etch time: 15–20 seconds per enamel or dentin surface.
- Rinse thoroughly: ≥10 seconds, blot excess water—leave substrate visibly moist for optimal bonding.
Indications
- Etching enamel and dentin in total-etch adhesive protocols
- Surface preparation for composite restorations, sealants, veneers, and adhesive bonding
- Removal of precipitated salts on etched porcelain prior to silanization.
Instructions for Use
- Isolate operative field with rubber dam or cotton rolls.
- Dry tooth surface before application.
- Attach a Blue Micro™ or Inspiral™ tip to the syringe.
- Dispense Ultra‑Etch precisely onto enamel or dentin; allow to dwell for 15–20 s.
- Rinse thoroughly for at least 10 s; blot dry leaving surface visibly moist.
- Proceed immediately with adhesive system per protocol.
Summary
The Ultradent Ultra‑Etch™ Kit (Ref. 163) brings precision and control to total‑etch bonding workflows. Its blue‑tinted, thixotropic gel architecture ensures accurate placement and reliable rinse‑off, while the self‑limiting etch depth creates optimized adhesion with minimal sensitivity. The included syringes and disposable tips make it a practical choice for efficient, high‑quality restorative procedures.
