n = 6 in each group; degree of freedom = 3; F value was calculated by one-way analysis of variance; H value was calculated by the Kruskal–Wallis test. value of the Levene test: day 3, 0.133; day 7, 0.173; day 14, 0.321; day 28, 0.613. Pairwise post hoc comparisons showed a significant difference () between the groups. ^#Pairwise intergroup differences were significant () except for the following: 0 mm–2 mm, 2 mm–4 mm, and 4 mm–intact.
