| Aim: to evaluate the color stability of direct composite resin veneers over an 18-month evaluation periods in vital anterior teeth. Materials & Methods: The studied samples consisted of 88 discolored vital anterior teeth in 20 patients aged between 18–40 years, these cases were divided into two groups: Group 1: OMNICHROMA (single shade) supra nano filled composite, and Group 2: Ceram. x spectra (multi-shade) nanohybrid composite. Window preparations of veneers were made to a depth of 0.3–0.5 mm on the labial surface of vital anterior teeth. Color change assessment (ΔE) were performed with a spectrophotometer VITA Easyshade V according to CIELab color coordinates by two calibrated investigators at baseline, 6, 9, 12 and 18 months follow up period. Results: One way ANOVA showed that there was highly statistical significant difference between color change values at different evaluation periods for each group I (F=15.8, P-value=0.000) and group II (F=16.68, P-value=0.000). Multiple comparisons Tukey's test revealed a statistically highly significant difference between the results of baseline, 6 and 9 months versus both 12 & 18 months follow up periods for each group I and II (P-value = 0.000).The independent t-test revealed that there was no statistical significant differences between both groups except at baseline and12 months follow up period where P-value recorded 0.025 and 0.023 respectively. Conclusion: Single and multi-shade composite veneers have comparable acceptable clinical performance regarding the color stability after 18 months follow up. | ||||
