Table 2.

Tooth movement during the first two weeks (T0-T1), the second two weeks (T1-T2), and the entire period (T0-T2) in millimeters

Period	Orthodontics only side (n = 10 rats)	Surgical side (n = 10 rats)	Δ in %	p-value
T0-T1	0.45 ± 0.29 (0.00, 0.85)	0.53 ± 0.29 (0.00, 0.88)	18	0.127
T1-T2	0.39 ± 0.21 (0.14, 0.74)	0.62 ± 0.26 (0.15, 1.18)	59	0.011*
T0-T2	0.84 ± 0.24 (0.29, 1.18)	1.15 ± 0.27 (0.59, 1.47)	37	0.000***

Values are presented as mean ± standard deviation (minimum, maximum).

Δ equals the increase produced by piezocision.

T0, initial; T1, 2 weeks later; T2, 4 weeks later.

Differences between two sides were tested by paired t-tests and considered significant at p < 0.05. *p < 0.05; ***p < 0.001.
