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

Table 1 SP 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	0.3665	0.0198	0.3524	0.3808
Occlusal Trauma	10	0.7432	0.0281	0.7231	0.7634
Orthodontic Force	10	1.0163	0.0025	1.0145	1.0181
Occlusal Trauma + Orthodontic Force	10	1.5021	0.0104	1.4947	1.5096

^aValues are presented as SP 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)
