Amount of crowding · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
It is very uncertain whether extraction of third molars (wisdom teeth) changes amount of crowding (Little's Irregularity Index, change) at 5 years compared with no active treatment (control) (very low certainty).

Amount of crowding · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
It is very uncertain whether extraction of lower deciduous canines changes amount of crowding (lower incisor crowding, change) at 1-2 years compared with no active treatment (control) (very low certainty).
