Precision Etching. Superior Bond Strength.
RHOOS® BOND-PREP 37 is a thixotropic 37% orthophosphoric acid gel used for etching enamel and dentin surfaces prior to adhesive and restorative procedures.
It effectively removes the smear layer and creates controlled microporosities required for strong mechanical bonding.
Unlike runny etchants, RHOOS® BOND-PREP 37 does not flow uncontrollably.
Its non-drip gel formulation stays exactly where applied, giving the clinician full control during etching while protecting adjacent soft tissues.
The clean-rinsing formula washes off easily and completely, ensuring no residue is left behind to interfere with bonding performance.
Why Choose RHOOS® BOND-PREP 37?
Flows only when pressure is applied, then stays firmly in place — no unwanted run-off.
Clear contrast allows precise placement and easy verification of etched areas.
Rinses away completely with water spray, leaving a clean, residue-free surface.
Ensures accurate application even in posterior or difficult-to-reach areas.
Provides uniform etching for predictable and reliable bond strength.
Clinical Indications
- Etching of Enamel and Dentin for Composite Restorations
- Cementation of Inlays, Crowns, Bridges & Veneers
- Bonding of Orthodontic Brackets
- Pit and Fissure Sealant application
🧭 How to Use
1. Isolate
Clean and isolate the tooth surface
(Rubber dam recommended).
2. Apply
Apply RHOOS® BOND-PREP 37 directly onto enamel and/or dentin.
3. Wait
● Enamel: 15–30 seconds
● Dentin: 10–15 seconds
4. Rinse
Rinse thoroughly with water for 10–15 seconds to remove all gel.
5. Dry
● Enamel: Air dry
● Dentin: Blot dry (keep slightly moist for wet bonding)
Frequently Asked Questions (FAQs) – RHOOS® ENDOPREP-X
Is RHOOS® BOND-PREP 37 suitable for both enamel and dentin?
Yes. It is designed for the Total-Etch technique, making it suitable for effective conditioning of both enamel and dentin.
Does the gel flow or run during application?
No. RHOOS® BOND-PREP 37 has a thixotropic, non-drip consistency, which means it stays exactly where placed and does not flow uncontrollably.
How long should the tooth surface be etched?
- Enamel: 15–30 seconds
- Dentin: 10–15 seconds
Avoid over-etching dentin to prevent collagen collapse.
Is the gel easy to wash off after etching?
Yes. The formulation is designed to rinse off cleanly and completely with water spray, leaving no residue behind.
