Abstract

Purpose: To compare digital photography to spectrophotometry in evaluating the color stability of resin composite. Materials and methods: Thirty- two disc-like specimens of Filtek Z350 resin composite were prepared and color-assessed; before and after 30 days of submersion in coffee solution. For each specimen, color was assessed according to Commission Internationale de I’Eclairage (CIE) color space values using: Two different versions of Canon Digital Single Lens Reflex (DSLR) camera; with standard lenses, flash, and settings: Canon 600d (Group I) and Canon 1100d (Group II), and a digital spectrophotometer (Vita Easyshade advance 4.0; Vita Zahnfabrik, Bad Sackingen, Germany) as a control (group lll). Color change (ΔE) was recorded for individual devices, tabulated, and statistically analyzed using oneway ANOVA, then Tukey’s post hoc test (P ≤ 0.05). Results: Statistically, no significant difference appeared among the used devices (P≤ 0.05) while assessing the color stability of Filtek Z350 resin composite. Conclusions: Both devices are similarly valuable for color assessment of resin composite.
