Effect of an Experimental Opaque Resin on Composite Layering 㸫 An experimental opaque resin based on s-TP standard curve informations 㸫 Abstract

The colors of most of the commercial resin composites are known to be

synchronized to the Vita shade guide; a composite of a color similar to the adjacent tooth substance is chosen and filled into a cavity surrounded by a healthy tooth color, thereby achieving an aesthetic restoration. It has been reported that the color of most of the healthy dentins is equivalent to Vita shade A3.5. Accordingly, the author considered that the opaque resins which have a color equivalent to A3.5 may enable most of the

commercial resin composites to achieve restorations in expected colors by layering with these opaque resins.

Thus, in this study, a composite type resin cement which is equivalent to Vita shade A3.5 in color was prepared by formulating pigments as an adjusting material-A3.5 for opaque resins. Then, the relationship between the masking range and the thickness of the material was obtained from an s-TP standard curve yielded by varying the

background colors and thicknesses of the adjusting material-A3.5. We prepared an experimental opaque resin containing four times the amount of pigments in the adjusting material-A3.5. The 0.5 mm thick experimental opaque resin was overlaid with respective commercial flowable resin composites, A3, B3, and C3, in varying thicknesses, and the background-color masking ranges and the macroscopic colors were evaluated.

As a result, the following conclusions were obtained:

1. A 0.5 mm thick experimental opaque resin showed a background-color masking range equivalent to the one yielded by the resin composite corresponding to the adjusting material-A3.5 of 1.0 mm in thickness.

2. Based on the relationship between the background-color masking ranges and thicknesses of the samples presented by the layering samples of the 0.5 mm thick experimental opaque resin with the commercial flowable resins, it is expected that a color difference of 70㸫which is clinically hypothesized as significant black

coloration㸫can be masked by B3 or C3 if their thickness is 1.0 mm, and that the background color will be slightly visible with A3.

3. In the macroscopic evaluation, layering samples of the 0.5 mm thick experimental opaque resin with a 1.0 mm thick flowable resin㸫which were placed on a belt-like background of background-color difference 70㸫, the background-color masking effects were assessed as identical in B3 and C3. Additionally, in a comparison using A3, a belt-like background in the background color was slightly noted.
