[Comparison of the film thickness of composites of different degrees of viscosity].

The measurement of the film thickness of the composite cement Variolink Esthetic («Ivoclar-Vivadent», Liechtenstein) and the microhybrid composite Enamel («Micerium», Italy) was carried out according to ISO 4049: 2009 standards with a load force of 5 kg. While reducing the load force to 5 kg, all materials showed an increase in the film thickness; the film thickness of the Variolink Esthetic composite cement was changed from 23 microns (at 15 kg) to 32 microns (at 5 kg), and the film thickness of the microhybrid composite film Enamel was changed from 39 microns (at 15 kg) to 102 microns (at 5 kg). After preheating, the film thickness was changed from 23 microns (at 15 kg) to 44 microns (at 5 kg).
