II (Gutta-percha/AH Plus)
Subgroup A	42.57±1.1^D,𝛼	59.06±0.98^D,𝛽	65.50±1.17^D,𝜒
Subgroup B	30.88±1.02^E,𝛼	24.40±0.92^E,𝛽	37.8±1.29^E,𝜒
Subgroup C	21.80±1.21^A,𝛼	20.21±1.3^F,𝛼	18.58±0.98^B,𝛽

Mean values that share a superscript letter were not significantly different at the 5% level within the same root third (ANOVA, Bonferroni; 𝑃>0.05). Between the root-thirds, groups that share the same superscript symbol were not significantly different from each other (𝑃>0.05).
