Histopathological analysis of the effect of ZA on root resorption, expressed in scores. Significant bold value if p < 0.05.

Scores root resorption
Days	Scores (median/maximum − mínimum)	p-value
Naive	0 (0–0)	a, b
Saline	6 (6–6)	a
ZA (0.2)	3.5 (3–4)	b
ZA (1.0)	2 (2–2)	c

(a) Association between the Naive versus Saline groups—p < 0.000. (b) Association between the Naive versus ZA groups (0.2)—p = 0.015. (c) Association between the Saline versus ZA groups (1.0)—p = 0.015 (Kruskal–Wallis test followed by pos-hoc Dunn's test).
