Table 5. Mean values and standard deviations of the Ca/P ratio according to treatments and evaluation times.
| Treatments | Ca/P (T 0 ) | Ca/P (T B ) | Ca/P (T 14 ) |
|---|---|---|---|
| LED | 2.33 (0.88) ABa | 1.98 (0.68) Aa | 1.96 (0.80) ABa |
| LED/CP | 1.76 (0.98) Bab | 1.59 (1.12) ABa | 2.30 (1.52) ABb |
| CP | 2.65 (1.38) Aa | 2.37 (1.59) Aa | 2.49 (1.02) Aa |
| LED/HP | 1.79 (0.94) Ba | 1.40 (0.88) Ba | 1.68 (1.07) Ba |
| HP | 2.14 (0.71) ABa | 1.85 (0.87) ABa | 2.19 (1.13) ABa |
Means followed by different letters differ statistically at 5% significance level, according to two-way repeated measures ANOVA and Tukey Test.
Uppercase letters compare treatments and lowercase letters compare evaluation times.
T 0 (baseline), T B (after bleaching) and T 14 (14 days after bleaching).
