Incidence of eruption of the PDC into the mouth · 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 led to higher incidence of eruption of the PDC into the mouth compared with single primary (canine) tooth extraction; GRADE not reported.
