  1. Different pretreatment methods and aging regimens are represented by the rows. Different attachment materials are represented by the columns. Statistical significance of differences (p ≤ 0.05) is indicated by superscript letters or numbers. Values that do not differ significantly share the same letter/number. In the rows different uppercase letters indicate significant differences between storage regimens and different numbers between pretreatment methods. Different lowercase letters indicate significant differences in the lines (between attachment materials).
