Intra- and inter-group differences in the intercanine width change measured at different time-points

Variable	Study group	Control group	p-value*
ΔT0-T1 (mm)	0.0 ± 0.0	−0.1 ± 0.3	0.541
ΔT1-T2 (mm)	0.0 ± 0.0	−0.1 ± 0.3	0.548
ΔT2-T3 (mm)	0.0 ± 0.2	−0.3 ± 0.7	0.548
ΔT0-T3 (mm)	0.1 ± 0.1	−0.4 ± 0.7	0.250
p-value†	1.000	0.923

Values are presented as mm ± standard deviation.

T0, at baseline; T1, at 1 month; T2, at 3 months; T3, at 6 months.

*Mann-Whitney U test or ^†Friedman test for repeated measures were used to compare intergroup or intragroup difference, respectively.
