Ionoseal is a light-curing glass ionomer composite cement for linings, extended fissure sealing and treatment of smaller lesions.
Ionoseal – Method of use:
1. Prepare the cavity according to the rules of the filling technique. The tooth surface should be fully dried. Avoid contamination.
2. Cover areas in proximity of the pulp with a calcium hydroxide preparation. It is recommended to provide an adhesive bond (especially in cavities that do not have enamel on all sides).
3. Ionoseal tube/syringe: Apply the required quantity of Ionoseal directly from the tube onto the instrument or apply directly from the syringe. Avoid contamination and disinfect after use. For linings in excess of 1 mm thickness, apply and cure in layers. In order to ensure the function of the nondripping syringe do not pull back the plunger during or after use.
4. To light-cure this material, conventional polymerisation devices are suited. The light output should be a minimum of 500 mW/cm2 for halogen polymerisation devices and 300 mW/cm2 for LED devices. Light source should be positioned as close as possible to the surface (approx. 2 mm). Cure for at least 20 s. For a greater distance, prolong curing time.
5. Finish the Ionoseal surface with a rotary instrument and place the filling according to the manufacturer’s instructions.
– Ionoseal adheres to materials such as crown and bridge materials, methacrylate-based temporary obturation materials and certain impression materials (e. g. polyether), which may lead to damage to or removal of the lining. Apply a bond in these cases.
– Due to the extreme stability of Ionoseal after curing, it is not possible to remove excess material with a probe. This could loosen the entire lining. Use a rotary instrument for this purpose.
– Ionoseal contains Bis-GMA, diurethanedimethacrylate, BHT and glass ionomer powder. Do not use in patients with known allergies to these ingredients.
– Preparations for pulp protection or dentine isolation should always cure or dry prior to the application of Ionoseal (see instructions for use of these products) in order to prevent a reduction in the adhesion to dentine.
– After removal from the box avoid exposing Ionoseal to direct light (e.g.: operating light or daylight) and apply as soon as possible.
– Eugenol or other phenolic substances (e. g. thymol) impede the polymerisation of Ionoseal. Avoid any contact with these materials.
– Insufficient curing times or luminous intensity also lead to incomplete curing. Check the curing light and light guide regularly.
Store Ionoseal tightly closed and light-protected at room temperatures between 4°C – 23°C. Refrigeration prolongs the shelf life. Prior to application, the material must reach room temperature again. Do not use after expiry date. The vertical storage of opened tubes in the standtray (detachable) allows immediate availability of Ionoseal at all times.
