| Heart rate (HR) (Mean ± SD) beats/min |
CC-ILA (Test group) |
IANB (Control group) |
P value |

| HR during extraction (c) | 107.68 ± 14.33 | 114.44 ± 19.57 | 0.17 |
| Mean change in HR during injection (b–a) | 4.72 ± 3.12 | 14.68 ± 8.91 | < 0.0001* |
| P value§ | P < 0.0001* | P < 0.0001* | |
| Mean change in HR during extraction (c–b) | 3.04 ± 9.05 | 0.96 ± 11.97 | 0.49 |
| P value§ | P = 0.32 | P = 1.00 | |
| Mean change in HR from baseline to extraction (c–a) | 7.76 ± 10.56 | 15.64 ± 9.53 | 0.01* |
| P value§ | P = 0.004* | P < 0.0001* |
*Statistically significant at P value < 0.05
T tests were used to compare means; SD: standard deviation
§Repeated measure ANOVA was used with Bonferroni post hoc corrections for pairwise comparisons
