Abstract

The demand for aesthetic restoration is a key factor in the placement and popularity of direct composites. New technologies have been implemented over a period of time in the shade matching of composites, which is more reliable than the conventional approach to date. Difficulty with rapidly evolving technologies and inflationary pressure due to increased costs can be the reason why most practitioners use the Vita classic shade guide as traditional method. These traditional shade guides are often manufactured according to the properties of porcelain materials rather than composite resin options.
Aim: This article compares the color difference (?E) between Vita classic shade tab and customized composite shade tab using spectophotometric analysis for predictable shade matching in direct composite restorations.
Materials and Methods: In order to compare the customized composite shade tab (A1 and A2) with the regular Vita classic shade tab (A1 and A2), five A1 and A2 shade tabs were fabricated from two separate composite brands (AmelogenTM Plus-ULTRADENT, Coltene Brilliant) in order to obtain a total of twenty samples (n=5 each). The fabrication of the customized shade tabs was done using Smile line Style Italiano mini guide kit. All the twenty samples, (customized composite A1, A2 shade tabs) and the Vita classic A1 and A2 shade tab were subjected to spectrophotometric analysis using Data color 650 sphectrophotometer to measure the CIE-Lab values. Based on CIE-Lab parameters obtained from computerized spectrophotometry digital reading of A1, A2 customized composite shade tab and A1, A2 Vita classic shade tabs, the Euclidean distance (?E) between two color points (composite-Vita classic) was calculated for the determination of color differences.
Conclusion: There was a perceptible color difference between the most commonly used Vita classic shade tab and the customized shade tab. Therefore, shade matching in direct composite restoration requires customized composite shade tabs to achieve predictable results.

Keywords: Shade guide, Spectrophotomter, Shade matching, Customized composite shade tab.
