Table 2.
Inter- and intra-group distribution of intrusion at centroid point to PP for incisor position.
| CP to PP distance (mm) | Group 1 (n = 15) Mean ± SD |
Group 2 (n = 15) Mean ± SD |
Inter-group comparison (P-value for unpaired ‘t’ test) |
|---|---|---|---|
| Pre-intrusion | 17.4 ± 1.3 | 16.4 ± 1.3 | 0.047 (S) |
| Post-intrusion | 14.3 ± 1.2 | 14.3 ± 1.1 | 0.937 (NS) |
| Amount of change (Pre–Post) | 3.10 ± 0.67 | 2.07 ± 0.53 | 0.001 (S) |
| Intra-group comparison (P-value for paired ‘t’ test) Pre v/s Post |
0.001 (S) | 0.001 (S) |
P-value < 0.05 is considered to be statistically significant. S: Significant, NS: Non-Significant.
