2400 to 2800 ppm F toothpaste vs 1450 to 1500 ppm F toothpaste

Caries increment, surface index D(M)FS · Children and adolescents with immature permanent dentition (aged 5 to 16 years at study start)

2400 to 2800 ppm F toothpaste showed no clear difference in caries increment, surface index D(M)FS compared with 1450 to 1500 ppm F toothpaste (moderate certainty).

440 to 550 ppm F toothpaste vs 250 ppm F toothpaste

Caries increment, surface index D(M)FS · Children and adolescents with immature permanent dentition (aged 5 to 16 years at study start)

440 to 550 ppm F toothpaste showed no clear difference in caries increment, surface index D(M)FS compared with 250 ppm F toothpaste (low certainty).

Women who experienced preterm birth vs Women who did not experience preterm birth (term)

Decayed, missing, filled surfaces (DMFS) · pregnant women

Women who experienced preterm birth did not have a significantly different DMFS than those who did not (mean difference -0.15, 95% CI -3.40 to 3.09; 3 studies; I2=89%); certainty of evidence not graded.

  • Dental caries and preterm birth: a systematic review and meta-analysis. 2018 All outcomes
    Pregnant women assessed around delivery in observational studies across multiple countries (Mexico, Malawi, India, France, Jordan, Finland, Tanzania); mostly retrospective cohort and case-control designs
    MD -0.15 [-3.40, 3.09]

Fluorides combined with CPP-ACP vs Fluorides alone (monotherapy)

Total lesion area divided by total surface area (visual) · Patients with early caries lesions in permanent teeth (non-fluoridated water area)

Adding CPP-ACP to fluorides did not significantly change the lesion-area outcome for smooth-surface early caries lesions versus fluorides alone; not GRADE-rated.

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Filled primary surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

Fluoride supplementation (tablets, drops, lozenges or chewing gum) showed no clear difference in filled primary surfaces at 5 years compared with placebo or no treatment; GRADE not reported.

Resin-based fissure sealant (2nd/3rd/4th generation) vs No sealant (control/no treatment)

Caries on occlusal surfaces of permanent molars (12 months) · Children and adolescents (general population, aged under 20 years)

Resin-based fissure sealant (2nd/3rd/4th generation) led to lower caries on occlusal surfaces of permanent molars (36 months) compared with no sealant (control/no treatment); GRADE not reported.

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed primary surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

Fluoride supplementation (tablets, drops, lozenges or chewing gum) showed no clear difference in decayed primary surfaces at 3 years compared with placebo or no treatment; GRADE not reported.

Intervention not reported

Elimination of all clinical signs of ocular surface inflammation ('complete success'), preferably measured by a composite grading system, at three months (± one month) after start of treatment · children with blepharokeratoconjunctivitis

The review found no eligible studies for this question.

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed or filled primary tooth surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

It is very uncertain whether fluoride supplementation (tablets, drops, lozenges or chewing gum) changes decayed or filled primary tooth surfaces at 3 years compared with placebo or no treatment (very low certainty).
