iBOND Etch Gel and Fluid are etching agents based on orthophosphoric acid.

Your benefits at a glance
• Clean and easy application
• Reliable identification thanks to the colour of the gel
GLUMA Etch Gel is used for enamel etching and enamel/dentine etching using the total etch technique
prior to the adhesive bonding of:
• Composite and compomer restorations
• Laboratory-fabricated, indirect restorations (e.g., inlays, crowns, bridges, veneers)
• Sealants.
- APPLICATIONS:
Prior to treatment, carefully clean tooth with fluoride-free polishing paste. The use of a rubber dam is recommended. After
preparation in accordance with adhesive filling therapy, rinse the cavity and dry with oil-free air.
1st step:
1. Starting from the bevelled enamel areas, apply GLUMA Etch to the entire cavity surface, including the dentine. Ensure that the
enamel is etched for at least 20 sec and no more than 30 sec, and that the dentine is conditioned for at least 15 sec and no more
than 20 sec. When using pay special attention to complying with the dwell time on the dentine. Reducing the time to 15 sec in
these areas is permissible to avoid overetching. If desired, only apply GLUMA Etch to the enamel and let set for a maximum of 30
sec. Etch unprepared enamel, e.g. in case of fissure sealing, for at least 30 sec and no more than 60 sec. In case of fluoridated
enamel, etching for no more than 60 sec may also be required.
Caution: In case of deep cavities, we recommend covering the dentine near the pulp with a calcium hydroxide preparation and a
base (e.g. glass ionomer cement) prior to etching.
2nd step:
3. Dry the cavity with oil-free air (do not dry out dentine!). The etched enamel surface should appear chalky white. In case of
contamination of the tooth surface (e.g. with saliva), the etching must be repeated (for a maximum of 10 sec dwell time).
