Fluoride toothpaste 550 ppm (lower concentration) vs Fluoride toothpaste 1000 ppm or more (higher concentration)

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years

Fluoride toothpaste 550 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1000 ppm (higher concentration) (moderate certainty).

Low-power CO2 laser irradiation (LLLT, 0.5 to 2 W) vs Placebo (placebo laser or placebo agent) or no treatment

White spot lesion incidence · High caries-risk patients: fixed-orthodontic-appliance patients and children with partially erupted permanent molars

Low-power CO2 laser (LLLT) is associated with a lower incidence of new white spot lesions than placebo (OR 0.21, CI 0.15 to 0.30; ungraded, 3 RCTs, considerable heterogeneity I2=71%).

Slow-release fluoride device (fluoride glass beads) vs placebo or usual care

Caries increment, surface index D(M)FS · Children with high risk of dental decay

It is very uncertain whether slow-release fluoride device (fluoride glass beads) changes increase in DMFS at 2 years compared with baseline compared with placebo or usual care (control) (very low certainty).

Slow-release fluoride device (fluoride glass beads) vs placebo or usual care

Caries increment, tooth index D(M)FT · Children with high risk of dental decay

It is very uncertain whether slow-release fluoride device (fluoride glass beads) changes increase in DMFT at 2 years compared with baseline compared with placebo or usual care (control) (very low certainty).

Low socioeconomic status and family financial stress vs Higher socioeconomic status and lower stress

Salivary cortisol, cariogenic bacterial load and dental caries · Kindergarten-age children

In one cross-sectional study of children, low socioeconomic status, higher basal salivary cortisol and higher cariogenic bacterial counts were each independently associated with higher dental caries risk; not pooled (ungraded).

Prophylactic platelet transfusions with low‐dose schedule vs high‐dose schedule

Number of participants with WHO grade 3 or 4 bleeding up to 30 days from study entry · People with a haematological disorder

Prophylactic platelet transfusions with low‐dose schedule showed no clear difference in number of participants with WHO grade 3 or 4 bleeding up to 30 days… compared with high‐dose schedule (low certainty).

Prophylactic platelet transfusions with low‐dose schedule vs high‐dose schedule

Mortality from all causes up to 30 days from study entry · People with a haematological disorder

Prophylactic platelet transfusions with low‐dose schedule showed no clear difference in mortality from all causes up to 30 days from study entry compared with high‐dose schedule (low certainty).
