Ultra-Etch, 35% Phosphoric Acid Solution

Clinical Overview

Ultra‑Etch™ is a 35% phosphoric acid gel formulated for precise total‑etch conditioning of enamel and dentin. Its unique thixotropic viscosity supports accurate placement without slippage, while its self‑limiting chemistry produces an average etch depth of ~1.9 μm after ~15 seconds—creating an ideal surface for resin penetration with reduced post‑op sensitivity.

Key Benefits

• Self‑limiting etch (~1.9 μm): Optimizes adhesive infiltration and minimizes over‑etching.
• Ideal viscosity: Adheres to application site—won’t run on vertical surfaces, yet penetrates fissures.
• Blue tint: Enhances visibility during placement and confirms complete rinsing.
• Residue‑free rinsing: Cleans away fully for seamless adhesive interface.
• Bulk refill format: 30 mL syringe supports high-volume practices with fewer interruptions.

Kit Contents

• 1 × 30 mL IndiSpense® syringe of Ultra‑Etch 35% phosphoric acid gel (Ref. 685)
• (Delivery tips sold separately; compatible with Blue Micro™ or Inspiral™ Brush tips)

Application & Protocol

• Etch time: 15–20 seconds for enamel and dentin to achieve ~1.9 µm etch depth.
• Optional use: Apply for ~5 seconds on etched porcelain to remove etch salts before silane application.
• Rinsing: Rinse thoroughly, blot lightly—leave enamel/dentin surface visibly moist prior to bonding.

Indications

• Enamel and dentin etching in total‑etch adhesive protocols
• Preconditioning tooth surfaces for composite restorations, sealants, and adhesive bonding
• Removal of surface salts on etched porcelain prior to silane application in restorative workflows.

Instructions for Use

1. Isolate operative field (e.g. rubber dam or cotton rolls).
2. Dry the tooth surface before application.
3. Attach Blue Micro™ or Inspiral™ tip to the syringe.
4. Apply gel precisely to the target surface; leave for 15–20 s.
5. Rinse thoroughly with air/water spray for ≥10 s; blot dry leaving substrate visibly moist.
6. Proceed immediately with adhesive bonding protocol.

Summary

Ultradent Ultra‑Etch™ Refill (Ref. 685) delivers highly controlled etching performance through its self‑limiting etch chemistry, ideal viscosity, and visible blue tint. Designed for predictable adhesive preparation on enamel and dentin, this refill-grade 30 mL syringe is ideal for clinics requiring consistent, high-efficiency etching workflows.
