Analysis of Self-Adhesive Resin Cement Microshear Bond Strength on Leucite-Reinforced Glass-Ceramic with/without Pure Silane Primer or Universal Adhesive Surface Treatment

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)
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.
