Age	13.959±2.174	13.591±1.802	NS
Social	78.455±22.550	99.408±18.351	<0.001

Global score	80.459±19.805	97.646±14.831	<0.001

Notes:

a P-value ≤0.05 was considered statistically significant. Bonferroni corrected values. The data in the Dental crowding and No dental crowding columns are shown as mean ± standard deviation.

Abbreviation: NS, not significant.
