Effect of cure time and temperature on the bulk adhesion of ELP[KEY₄-48]. Adhesion strengths versus cure times are shown at (a) 22°C, (b) 37°C and (c) 55°C. Groups with identical letters are statistically similar (p > 0.05) when determined by one-way ANOVA followed by Tukey's HSD post hoc analysis. (d) The same data are grouped by cure time. Groups that share a letter are statistically similar (p > 0.05) when determined by a one-way ANOVA (performed within a single time point) followed by either Tukey's HSD or the Games–Howell post hoc test. Adhesion strength increased with cure time and temperature up to 6–12 h, after which adhesion strength remained constant at all temperatures. Two-way ANOVA results indicate that the relative adhesion strengths varied according to 22°C < 37°C, 55°C and 1 min, 5 min < 1 h < 3 h < 6 h < 12 h, 24 h, 7 days.
