Background: Restorative dentistry aims to reproduce natural tooth shades through resin composites that must be layered to obtain colors, opacities, and translucencies, and therefore, clinical success is operator skill dependent. Aims: The purpose of this study is to evaluate the color shift of single-shade composite restorations before and after dental bleaching. Materials and Methods: Eighty human extracted posterior teeth were restored with four single-shade composites (Omnichroma OM; Clearfil Majesty ES-2 Universal CL; Essentia Universal ES; Venus Diamond One VE) (n = 20 each). Standardized V class cavities were prepared on buccal side. VITA Easyshade V spectrophotometer was used to register VITA color and color coordinates 24 h before (T0), 24 h after (T1), and 1 week after (T2) dental bleaching (Opalescence Boost PF 40%). Color differences (ΔEab) and (ΔWID) were calculated and subjected to statistical analysis. Statistical Analysis: Categorical variables were analyzed using Pearson Chi-square, and data from color coordinates were analyzed using one-way analysis of variance and Tukey’s multiple comparison test with Bonferroni correction. Paired t-tests were performed to compare continuous measures between groups and treatment time. Results: Instrumental evaluations revealed statistically significant differences between materials (P < 0.05) with lower values for ES and VE samples followed by CL and OM at T0 and T1. At T2, OM and CL ΔEab values decrease getting closer to ES and VE. Conclusion: Single-shade composites seem to match with the surrounding bleached tooth.

“…Bleaching can sometimes remove acquired stains on composites and return them to their original shade. However, bleaching is not able to change the shade of composite restorations to a lighter color as it would on a natural tooth structure [13,21,22].…”

Effect of bleaching on the color match of single-shade resin composites

Purpose: To evaluate the color match of single-shade resin composites before and after bleaching procedures, through instrumental and visual analyses. Methods: Class V cavities were created on the buccal surfaces of 80 extracted human molars, restored with 4 single-shade composites (Omnichroma; Clearfil Majesty ES-2 Universal; Essentia Universal; Venus Diamond One). A spectrophotometer (VITA Easyshade V) was used to evaluate the tooth/resin color match before (T 0 ), and 24 h (T 1 ) and one week (T 2 ) after dental bleaching (Opalescence Boost PF 40%). Color variations (ΔE 00 ) were calculated and statistically analyzed (P < 0.05). Visual analysis was performed before and after tooth bleaching. Results: Spectrophotometric evaluations revealed statistically significant differences between materials at T 0 , T 1 , and T 2 (P < 0.05). Visual analysis reported excellent and very good grades (0 and 1, respectively), irrespective of the materials and timepoints. Conclusion: Data seem to indicate that single shade composites are able to shift their color when the surrounding tooth undergoes bleaching effects. Single-shade composites seem to achieve a good color match with the surrounding tooth structure, before and after professional bleaching.
