To avoid sensitivity issues, staining, and secondary carries it is essential to have superior margin integrity. As you can see in the dye penetration specimen below, Simplicity eliminates these issues.

The driver behind these results is Simplicity’s ability to thoroughly etch enamel. To ensure proper levels of enamel etching the conditioner must reach a pH level below 3. Simplicity provides a pH well below 3, to ensure safe and proper etching of enamel surfaces. Below is a comparison of the efficacy of etching using a standard 37% phosphoric acid and Simplicity 1.

Most of the other self-etching materials do not etch enamel as well as Simplicity and therefore may exhibit staining or margin fractures over time. Simplicity has been designed to provide long lasting, superior results.
