Conclusion:

The etching acid of material 1 has better viscosity, as it behaves as a thixotropic gel with adequate consistency. It is possible to respect the total etching protocol, in which the acid should be applied first only on enamel for 15 to 20 s and then left to act on dentin for 5 to 10 s. This procedure is difficult to execute completely with the etching acid of material 2, due to its high run-off.

The shade provided by the manufacturer mimicked adequately in most of the samples, even though the teeth were of a different shade within the vita shade guide.

Polishing and shining is optimal
