| Abbreviations: GIC, glass ionomer cement; SD, standard deviation. A, B Means followed by the same single letter do not express statistically significant difference ( p >0.05). AB Means followed by different letters express statistically significant difference ( p < 0.05). # p = Friedman's nonparametric test, followed by the Dunn multiple test (in-line, upper case). * p = Kruskal–Wallis non-parametric test, followed by Dunn's multiple-comparison test (column, lowercase). | ||||||||||
