Sociodemographic / socioeconomic factors (single-parent family, low parental education, family income, socioeconomic status) vs Absence of the factor / reference socioeconomic category

Caries increment in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Evidence on the association between sociodemographic/socioeconomic factors and permanent-teeth caries is weak and inconsistent (3 studies; could not be pooled; not GRADE-rated).

Caries in first and second primary molars vs Reference (other primary tooth locations / caries-free)

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Caries in the first and second primary molars is the strongest tooth-specific predictor of caries in permanent teeth (RR 3.4; single study; not GRADE-rated).

Primary dentition DMFT score 1-3 vs No caries in primary teeth (DMFT = 0)

Caries prevalence in permanent dentition · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

A primary-dentition DMFT of 1-3 is associated with 1.5 times higher risk of caries in permanent teeth (single study; not GRADE-rated).

Dentinal caries in primary dentition (at 5 years) vs Caries-free primary dentition

Dentinal caries in permanent (newly erupted) teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Dentinal caries in the primary dentition is associated with about 3.2 times higher odds of dentinal caries in permanent teeth (single study; not GRADE-rated).

Primary dentition DMFT score over 13 vs No caries in primary teeth (DMFT = 0)

Caries prevalence in permanent dentition · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

A primary-dentition DMFT over 13 is associated with about 15 times higher risk of caries in permanent teeth (single study; not GRADE-rated).

Caries in upper primary incisors vs Reference (other primary tooth locations / caries-free)

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Caries in upper primary incisors has the lowest tooth-specific predictive value for permanent-teeth caries (RR 1.6; single study; not GRADE-rated).

1 finding from 1 review

High Streptococcus mutans colonization in primary dentition (age 2-3 years) vs Lower Streptococcus mutans load

Caries (DMFT/DMFS) in mixed/permanent dentition · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Higher early Streptococcus mutans colonization is associated with more caries in the mixed/permanent dentition (2 studies; not pooled; not GRADE-rated).

Enamel caries in primary dentition (at 5 years) vs Caries-free primary dentition

Dentinal caries in permanent (newly erupted) teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Enamel caries in the primary dentition is associated with about 1.6 times higher odds of dentinal caries in permanent teeth (single study; not GRADE-rated).

1400/250 ppm F (amine F/SnF2) toothpaste + mouthrinse, daily vs 1400/250 ppm F (NaF) toothpaste + mouthrinse, daily

Gingival bleeding (various bleeding indices) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)

It is very uncertain whether 1400/250 ppm F (amine F/SnF2) toothpaste + mouthrinse, daily changes gingival bleeding index (mean change from baseline) compared with 1400/250 ppm F (NaF) toothpaste + mouthrinse, daily (very low certainty).

White spot lesion index (mean change from baseline) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)

It is very uncertain whether 1400/250 ppm F (amine F/SnF2) toothpaste + mouthrinse, daily changes white spot lesion index (mean change from baseline) compared with 1400/250 ppm F (NaF) toothpaste + mouthrinse, daily (very low certainty).

Number of participants with new demineralised lesions (DLs) · Orthodontic patients of any age with fixed braces (new DLs assessed at debond)

Professionally-applied fluoride varnish (7700 or 10,000 ppm F),… showed no clear difference in number of participants with new demineralised lesions (DLs) compared with non-fluoride (placebo) varnish (low certainty).
