Comparison of percentages of force decay of (A) untreated control, (B) Corsodyl, (C) Curasept, (D) cigarette smoke (CS), (E) CSE + Corsodyl, and (F) CSE + Curasept treated Dentaurum (black) and Masel (red) elastic ligatures at 50 mm extension. *** p < 0.0001 vs. Dentaurum, (n = 6/group; two-way ANOVA and Sidak post hoc tests). Force degradation of (G) Dentaurum and (H) Masel elastic ligatures to external factors during the 4-week-long protocol. ## p < 0.005, ### p < 0.0005, #### p < 0.0001 vs. intact values; * p < 0.05, ** p < 0.005 highlightsdifference between two treatments at given time. (n = 6/group, two-way ANOVA, and Sidak post hoc tests).
