Indications:

• eruption of permanent molars and premolars with high initial level of mineralization (ILM) fissures;

 • eruption of permanent molars and premolars with an average ILM of fissures after a course of remineralizing therapy;

 • permanent molars and premolars in children before fixing fixed orthodontic equipment;

 • permanent molars and premolars in adults at risk of a cariesogenic situation in the oral cavity.

Methodology of conducting:

1. Clean the tooth with a mechanical brush and polishing paste. More effective cleaning of the chewing surface is carried out using sandblasting machines.

2. Isolate the tooth from the oral cavity and etch it with a 30-37% solution or a low viscosity liquid gel of phosphoric acid for 60 seconds.

3. Remove the etching agent with a jet of water for 40-60 seconds. Dried.

4. If necessary, an adhesive system is applied and polymerized

5. Apply sealant using a probe, cannula. The material is carefully distributed to avoid the formation of pores. The sealant is placed only in pits and fissures, it is impossible to cover the slopes of the hillocks with material. Excessive application of the material disrupts occlusion. At the same time, the pieces of sealant are chipped off, and new retention areas are created along the edges of the fragments for the accumulation of bacterial plaque.

6. Photopolymerize for 20-40 seconds.

7. Remove excess, control occlusion; if correction of the sealant is necessary, use diamond burs, finiers and polishes.

8. Local fluoridation is carried out.
