Teeth Eruption in Children with Normal Occlusion and Malocclusion

The aim of this study was to assess the differences in eruption of permanent teeth (C, P1, P2 and M2) in the group of children with and without malocclusion. A sample of 1758 children (921 boys and 837 girls), aged 8 - 13 was randomly selected. The subjects were grouped by chronological age (11 groups) and by presence of malocclusion. Statistically significant differences for the canines were found in the age group 11, for both upper and lower jaw (p<0.01). Statistically significant difference was found in the age group 8.5 for upper first premolars (p<0.05). For the second premolars, statistically significant differences were found for upper (p<0.01) in the age group 10, and for lower (p<0.05) in the age group 11. Premature loss of deciduous teeth can cause early eruption of permanent teeth that can lead to development of the malocclusion.
