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

Table 2 CGRP 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	0.0367	0.0019	0.0354	0.0382
Occlusal Trauma	10	0.0555	0.0020	0.0541	0.0569
Orthodontic Force	10	0.0749	0.0032	0.0727	0.0773
Occlusal Trauma + Orthodontic Force	10	0.0958	0.0028	0.0938	0.0979

^aValues are presented as CGRP 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)
