Expression of substance P, calcitonin gene-related peptide and vascular endothelial growth factor in human dental pulp under different clinical stimuli

Table 3 VEGF expression in human dental pulps of teeth with occlusal trauma, orthodontic force and a combination of both stimuli

Applied Stimuli^b	No. of teeth	Mean^a	SD	95% confidence interval
Healthy premolars control group	10	0.0004	0.0001	0.0003	0.0006
Occlusal Trauma	10	0.0010	0.0001	0.0009	0.0012
Orthodontic Force	10	0.0014	0.0001	0.0013	0.0016
Occlusal Trauma + Orthodontic Force	10	0.0025	0.0003	0.0023	0.0028

^aValues are presented as VEGF concentration in pmol per mg of dental pulp
The Kruskal–Wallis test showed statistically significant differences among groups (p < 0.001)
^bMann-Whitney’s U post-hoc pairwise comparisons (with correction of significance) showed statistically significant differences in all possible pairwise comparisons (p < 0.001)
