Extraction of the primary (baby) canine (single primary tooth extraction) vs No extraction (non-intervention control)

Number of participants referred for surgical exposure of the PDC · 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 number of participants referred for surgical exposure of the PDC compared with no extraction (non-intervention control) (very low certainty).

Moderate-severe active dental caries (exposure) vs Caries-free or mild dental caries (control)

Salivary IL-6 level (pg/mL) · Children and young adults (3-25 years)

Salivary IL-6 levels are significantly higher in children and young adults with active dental caries than in caries-free or mild-caries controls (SMD 11.60 pg/mL, 95% CI 6.27 to 16.94; 11 studies); ungraded.
