      GLUMA Etch 35 Gel contains 35% phosphoric acid and can cause chemical burns. May irritate eyes. Avoid contact with gingiva, skin, eyes or neighbouring teeth. In case of contact with oral mucosa, rinse thoroughly with plenty of water. If swallowed, thoroughly rinse mouth with water and then drink plenty of water. Consult a physician. In case of contact with skin, thoroughly rinse with soap and water. In the event of contact with eyes, rinse thoroughly with water and seek medical advice. Wear suitable protective gloves. Avoid skin contact. Wear protective clothing. Wear safety glasses/face protection. Immediately remove clothing contaminated with GLUMA Etch 35 Gel.


      GLUMA Etch Gel may be applied using a brush or cannula. Both brushes and cannulas are for onetime use only. To avoid cross infection, items intended for single use must be disposed of immediately after initial use. Release the plunger after applying the gel. Carefully reclose after removing product.

      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.

      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.
      2. Use a water sprayer to completely rinse off GLUMA Etch for 20 sec. The cavity must be completely free of any remnants.
      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).
