Glass ionomer cement (for bracket bonding) vs Resin adhesive

Initiation of white spot lesions (WSL), visual-tactile assessment · Patients of any age (11-40 years) receiving comprehensive/fixed orthodontic treatment with fixed appliances

There is no clear difference in WSL initiation between glass ionomer cement and resin adhesive for bracket bonding (RR 0.72, not significant); certainty of evidence is very low.

Dental caries prevalence · General population in Ethiopia (all ages, age range 6-100 years)

Cesarean section delivery vs Vaginal delivery

Caries prevalence (early childhood caries) · Toddlers and preschool children, 2 to 6 years of age (primary dentition)

Caesarean section delivery may be associated with a modestly higher prevalence of early childhood caries than vaginal delivery (pooled OR 1.48), but the evidence is inconsistent and of very low certainty.
