  1. Values are mean ± standard deviation. P value was calculated by independent samples ‘t’ test after confirming the underlying normality assumption. P < 0.05 was considered to be statistically significant. ICD, inter-canine distance; IMD, inter-molar distance; S, statistically significant; NS, statistically non-significant.
