Fissurit FX – highly filled light-curing fissure sealant

Fissurit FX
Fissurit FX is a white, light-curing fissure sealant with fluorides and high filler content (> 50%).

Fissures should be sealed as soon as the eruption of the tooth allows treatment and a dry work field can be secured.

After drying, thoroughly clean the surfaces to be sealed (rotating brush/cleaning paste free of fluorides), spray and dry.

In case of incipient carious lesions or unclear diagnosis extend the fissure with a fine instrument.


  • sealing/filling pits and fissures as well as small cavities
  • sealing/facing of damaged enamel surfaces
  • anchoring orthodontic appliances and covering caries predilection sites during orthodontic treatments
  • sealing composite or cement fillings (protective layer against humidity)
  • sealing carious lesions to stop them
  • restorating small defects in composite and amalgam fillings
  • sealing deciduous teeth


Apply Vococid etching gel (blue colour for control), work in with a short-haired disposable brush and let act for 15 – 30 s according to the condition of the enamel. Thoroughly rinse and dry. The etched enamel should have an opaque and matt-white appearance. Avoid subsequent contamination. Please refer also to the Vococid instructions for use.

Fissurit FX – syringe application:

fissurit fx fotoRemove the protective cap from the syringe. Place a new cannula on the Fissurit FX syringe. To avoid air bubbles, hold the syringe vertically and press the material up to the tip of the cannula.

Fissurit FX homogeneously flows from the cannula upon light to medium pressure. Check the cannula for clogging if stronger pressure becomes necessary.

Apply Fissurit FX from the margin into the fissure or cavity and let penetrate for 15 – 20 s. Remove any air bubble (e. g. with a fine probe). Important: Turn the piston of the syringe after application to relieve it from pressure and to avoid unnecessary flow of the material.


Polymerise Fissurit FX for 20 – 30 s per surface and check the sealing. To light-cure this material conventional polymerisation devices are suited. The light output should be a minimum of 500 mW/cm2 on halogen polymerisation devices and 300 mW/cm2 on LED devices.

Re-seal deficit areas, remove excess cautiously (e. g. finishing diamond) and polish if necessary (rubber polisher). Then apply a fluoride varnish on the treated and neighbouring teeth.


Remove the cannula of the syringe after use and attach syringe cap. Before next use of the syringe replace the direct application cannulae with a new one. Store Fissurit FX at temperatures between 4°C – 23°C and protect from light. Do not use Fissurit FX after the expiry date.

Advice and precautionary measures:

A work field which cannot be dried sufficiently involves the risk of a (partial) premature loss of the sealing. In these cases, the application of a fluoride varnish or sealing with a glass polyalkenoate cement is recommended until a perfect sealing is possible.

If the etched surface is contaminated (e. g. by saliva), the adhesion of Fissurit FX may be reduced. In case of contamination, clean, etch again for approx. 10 – 20 s, spray and dry.

Adhesion may be improved after etching by using a bonding (difficult drying or extended sealing). Expose Fissurit FX to operating light only a short time as otherwise polymerization will start (viscosity increases). Check sulcus after application and remove all material residue.

Fissurit FX contains Bis-GMA, diurethane dimethacrylate, BHT, benzotriazolderivate as well as sodium fluoride. Do not use in patients with hypersensitivities. Avoid contact with the mucosa as far as possible. Do not use cleaning and drying agents containing phenolic substances (e. g. eugenol, thymol) as they inhibit a complete polymerisation.

Carious lesions (e. g. around fillings) can be stopped by corresponding sealing if renewal of the filling is not desired or possible. For this purpose clean the corresponding areas, prepare as minimally as possible and etch in the enamel area. Sealing the complete filling is recommended. In cases of orthodontic treatments in areas of reduced oral hygiene, sealing those areas can provide good and permanent protection.

Fluoridation should be continued in all cases to protect the unsealed tooth areas from caries.
