CLEARFIL MAJESTY™ ES-2 Universal by Peter Schouten

The introduction of universal composites, which are not only universal in terms of application range but also in terms of shade adaptation, effectively marks the dawn of a new type of composite. This prompts a reinterpretation of the term "universal composite."

CLEARFIL MAJESTY™ ES-2 is a nanohybrid composite family. Nowadays, nanohybrid composites are commonly used as universal composites. They have a high filler content, they are strong, and they have exceptionally good polishability characteristics¹.

The newest variant in the CLEARFIL MAJESTY™ ES-2 range is CLEARFIL MAJESTY™ ES-2 Universal shade concept. For this composite; we expand the definition of universal and include shade coverage.

Posteriorly, a single material in a single shade is sufficient to cover the entire VITA™ range. This means that no shade determination is required. For the anterior zone, we offer two shade variants: a lighter and a darker variant (UL and UD). The lighter variant is used in the A1-A2 range and the darker for shades from A3 onwards. There is sufficient overlap between UL and UD ensuring no specific shade determination is necessary.

Finally, for situations that require extra lightness and brightness, an additional UW shade is available.

What makes CLEARFIL MAJESTY™ ES-2 Universal unique in comparison to other universal or single-shade composites?
The difference with CLEARFIL MAJESTY™ ES-2 Universal, is that without using an additional opaque composite, sometimes called a blocker, a successful, superbly matching restoration can be constructed. Not only with smaller cavities, but also with larger class I and II restorations. And, when used anteriorly, even an extensive Class IV restoration can be successfully constructed using CLEARFIL MAJESTY™ ES-2 Universal. So, it is not only for those small class III or V lesions.

Why Kuraray Noritake Dental Inc. can do this where others cannot, is to a large extent, thanks to optimized light diffusion technology (LDT). By using this technology in composites with the right translucency, the light is scattered and reflected in such a way that the composite blends in with the surrounding tooth structure.

Where others use the widely-employed chameleon effect, Kuraray Noritake Dental Inc. adds an extra dimension in the form of LDT. With the chameleon effect, light passes through the material and is reflected off the walls of the cavity. The perceived shade of the restoration is therefore the shade of the cavity walls. If the cavity is too large, thus requiring a larger amount of filling material, the light has to travel further and a large proportion of the light is absorbed. With this, the brightness of the restoration is reduced and the shade of the cavity walls no longer accurately reflected.

Our LDT allows light to be scattered within the composite itself, in addition to being reflected off the cavity walls. As a result, CLEARFIL MAJESTYTM ES-2 Universal is a particularly forgiving composite. This feature will be familiar to those who have used CLEARFIL MAJESTY™ ES-2 family products before.

CLEARFIL MAJESTY™ ES-2 Universal is the result of sophisticated filler, matrix and silane technology. It offers a solution for all your routine composite work. A consistently superb restoration where shade determination is a thing of the past.
