Incidence of successfully erupted PDC that were favourably positioned · Young people aged 9 to 14 years diagnosed with one or both palatally displaced permanent maxillary canines (PDC)
Double primary (canine and first molar) tooth extraction showed no clear difference in incidence of successfully erupted PDC that were favourably positioned compared with single primary (canine) tooth extraction; GRADE not reported.
