Ruby Etch 37% Phosphoric Acid 3 ml

Ruby Etch is a 37% phosphoric acid etching gel used to prepare enamel and dentin before bonding, composite restorations, and sealant placement. Supplied in a 3 ml syringe with fine applicator tips, it gives dentists controlled acid placement for reliable adhesive bond strength on both anterior and posterior restorations.

Clinical Uses

• Enamel and dentin etching before composite bonding
• Surface preparation for fissure sealant placement
• Etching prior to orthodontic bracket bonding
• Pre-treatment step before applying bonding agents

Key Features

• 37% phosphoric acid — the industry-standard etch strength for enamel and dentin
• Gel formulation stays on the target surface without running onto soft tissue
• Fine, pre-bent applicator tips for accurate placement
• 3 ml syringe sized for daily general-practice use

How to Use

1. Isolate the tooth and dry the surface.
2. Apply the gel to enamel first, then dentin, using the applicator tip.
3. Leave in place for the recommended etch time — typically 15-20 seconds on enamel, shorter on dentin.
4. Rinse thoroughly with water spray for the same duration as the etch time.
5. Dry gently and proceed with bonding agent application, then restore with composite.

FAQ

How long should I leave the etch gel on enamel?
Most 37% phosphoric acid etchants, including Ruby Etch, are left on enamel for around 15-20 seconds and on dentin for a shorter time (roughly 10-15 seconds) — adjust to your case technique.

Can Ruby Etch be used on dentin?
Yes, it suits the total-etch technique on both enamel and dentin, with a shorter application time on dentin to avoid over-etching and reduced bond strength.

Is Ruby Etch a gel or a liquid?
It's a viscous gel, which keeps the acid controlled on the target surface instead of running onto adjacent tissue.
