Colour Match Between Porcelain and PorcelainRepairing Resin Composites

Abstract

Abstract - The aim of this study was to evaluate the differences in colour between dental porcelain and porcelainrepairing resin composites. Porcelain discs were fabricated using four dentine shades in 1mm and 2mm thicknesses. Another series of discs was fabricated in 1mm and 2 mm thicknesses using three different brands of composite. Four single shades were used for the 1mm thick discs, and four single and 12 combined shades for the 2mm thick discs. The colour was measured using a spectrophotometer and colour differences ΔE* were calculated between samples. Colour differences were in the range of (ΔE*=3.5-26.9), above the accepted threshold for perceptibility (ΔE*>1) with a number above the threshold for what is considered to be clinically acceptable (ΔE*>5.5). Improvements in colour match were seen for certain shade combinations of repairing composites, in contrast to when a single shade of composite was used.

KEY WORDS: Colour match, Porcelain, resin composite.
