Table 4: Mean (Standard Error of the Mean) Sound, Initially Softened and Seven-Day Phase A Post Surface Microhardness (SMHs,
SMHi and SMHp, Respectively) Results Obtained by Vickers Microhardness Indents (N=10). Within each Column, One-Way ANOVA was Performed and Followed by Tukey b-test Comparisons to Identify Statistical Differences (p<0.05), which
are Indicated as 1<2. % SMHRp is Calculated using (SMHp – SMHi)/(SMHs - SMHi) x 100
