Infiltration – minimally invasive approach

Children are more likely to have fast pacing caries than adults. This is partly a result of an unfinished process of mineralization of teeth hard tissue after the eruption, and poor oral hygiene.

Icon technology is a minimally invasive, painless treatment of caries. The product (polymer) has to be applied to the demineralized enamel, impregnating and making it durable and resistant to bacteria. As a result, tooth decay stops and the natural tooth colour is gets restored.

Img. 1 – Patient – Lada, 13 years old. Complaints include sensitivity to temperature and unsatisfactory appearance of the front teeth. Directed for consultation from related professionals.
Oral cavity examination: chalky stains were found on the vestibular surface, which corresponds to the initial stage of caries in the stage of spot.
The diagnosis: tooth enamel decay 2.2, 2.3, 2.4 V class.
Given the critical situation it was decided to apply the ICON infiltration technology.

Isolating the working field with rubber dam system, tying teeth with floss for a better fit and secure isolation of the field.

Img. 3 – Etching of affected enamel with hydrochloric acid from ICON set, 3 iterations, 2 minutes each, until the partial disappearance of pigmented spots.
Flushing acid water for 1 minute.
Drying for 30 seconds.
Application of ethanol, resulting in complete dehydration.

Img. 4 – Application ICON infiltrate on the vestibular surface of demineralization centre for 2 minutes. Due to capillary forces the polymer penetrates the affected area -into dentin, 60 microns deep – and seals the pores.
Carrying out the polymerization for 40 seconds.
Repeated application of infiltration for 1 minute and the final polymerization.

Conclusions

With this method there is no need to carry out preparation of hard tissue, which by subsequent re-treatment leads to loss of tooth.
