Table 5 One-way ANOVA for comparison of color differences (between and within) observed among studied groups.
| Parameter time interval | Source of variation | Sum of squares | df | Mean square | F value | P value |
|---|---|---|---|---|---|---|
| ΔE00(I) | Between groups | 7.620 | 7 | 1.089 | 4.562 | 0.000* |
| Within groups | 17.182 | 72 | 0.239 | |||
| Total | 24.802 | 79 | ||||
| ΔE00(II) | Between groups | 45.709 | 7 | 6.530 | 18.598 | 0.000* |
| Within groups | 25.280 | 72 | 0.351 | |||
| Total | 70.989 | 79 | ||||
| df – degrees of freedom; F – variation between/within sample means; – probability value; ΔE00(I) – color change between pre-cementation and post-cementation measurements; ΔE00(II) – color change between post-cementation and post-thermocycling measurements. Statistical Interpretation: test used=one-way ANOVA; level of the degree of significance was determined on the value of * significant. | ||||||
