Table 3 The distribution of inter-canine and inter-molar distances according to sex

From: Association between breastfeeding duration, non-nutritive sucking habits and dental arch dimensions in deciduous dentition: a cross-sectional study

  Maxilla Mandible
ICD (cm) IMD (cm) ICD (cm) IMD (cm)
Male (n = 228) 4.05 ± 0.35 5.19 ± 0.33 3.56 ± 0.32 4.73 ± 0.32
Female (n = 187) 3.97 ± 0.32 5.10 ± 0.32 3.54 ± 0.33 4.66 ± 0.34
P value 0.024 (S) 0.007 (S) 0.446 (NS) 0.065 (NS)
  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.
