Repeatability of color measurements in multi-shade and single-shade resin composites of different thicknesses at different times: spectrophotometer versus mobile phone color applications.

ABSTRACT:

Objective

The aim of this study was to evaluate the short- and long-term repeatability of a spectrophotometer and three mobile phone color applications (MCAs) on the iPhone Operating System (iOS) platform for color differences of single-shade and multi-shade resin materials of different thicknesses.

Materials and methods

A spectrophotometer (Vita Easy Shade V) was used as a reference instrument. Three MCAs were used: ColorMeter RGB, Color Analyzer-Iro Shirabe, and Color Info Cam. Color measurements were performed on 1-mm and 2-mm thick specimens of resin composites: Charisma Smart (CS) / A1-A2-A3; Charisma Diamond One (C); Opallis (OP) / E1-E2-E3; Vittra APS Unique (V); Estelite Sigma Quick (ES) / A1-A2-A3; and Omnichroma (O) (n = 8). The specimens were measured at three tim
