Table 2.
Mean and standard deviation (SD) of microshear bond strength (in MPa).
| Group | Water storage (24 hours) | Thermocycling (10,000 cycles) |
|---|---|---|
| NC | 20.18 (2.01)c | 20.68 (4.60)b |
| SBU | 27.33 (2.81)b | 22.49 (4.11)b∗ |
| PC | 30.50 (3.40)a | 28.77 (3.52)a |
Within the same column, values with different superscript lower case letters are statistically significantly different (Tukey HSD, P < 0.05).
∗ indicates a significant reduction in bond strength for each group after 10,000 thermocycles (paired t-test, where P < 0.05).
NC: negative control; SBU: Single Bond Universal; PC: positive control.
