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.

Root resorption of adjacent permanent teeth caused by the PDC · Young people aged 9 to 14 years diagnosed with one or both palatally displaced permanent maxillary canines (PDC)
Extraction of the primary (baby) canine (single primary tooth… showed no clear difference in root resorption of adjacent permanent teeth caused by the PDC compared with no extraction (non-intervention control); GRADE not reported.

Table 4 (Naoumova 2015): probability of successful eruption depended on displacement severity; sector 2 (mild) 14/19 (74%) erupted vs sector 4 0/10 erupted; data refer to 59 teeth (mITT).

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.

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)
It is very uncertain whether extraction of the primary (baby) canine (single primary tooth… changes incidence of eruption of the PDC into the mouth compared with no extraction (non-intervention control) (very low certainty).
