Table 2 The distribution of malocclusion according to non-nutritive sucking habits

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

Parameters Sucking habit (n = 63) No sucking habit (n = 352) Pvalue
Breastfeeding <6 months    
Open bite 1 (3.1) 0 0.203 (NS)
Crossbite 0 20 (15.9) 0.014 (S)
Breastfeeding ≥6 months    
Open bite 0 2 (0.9) 0.999 (NS)
Crossbite 1 (3.2) 4 (1.8) 0.477 (NS)
Overall    
Open bite 1 (0.5) 2 (2.5) 0.379 (NS)
Crossbite 1 (3.8) 24 (21.2) 0.108 (NS)
  1. Values are n (% of cases). P value was obtained using a chi-square test. P < 0.05 was considered to be statistically significant. Non-nutritive sucking is a composite status of digit, thumb and dummy sucking. S, statistically significant; NS, statistically non-significant.
