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).

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).

Clinical examination with risk-based recall vs Clinical examination with 6-month recall

Dental caries: prevalence of root caries · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with risk-based recall showed no clear difference in dental caries: prevalence of root caries compared with clinical examination with 6-month recall; GRADE not reported.

Clinical examination with risk-based recall vs Clinical examination with 24-month recall

Dental caries: prevalence of root caries · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with risk-based recall showed no clear difference in dental caries: prevalence of root caries compared with clinical examination with 24-month recall; GRADE not reported.

Dental caries: prevalence of root caries · Dentate adults (aged 18 years and older) receiving dental check-ups in UK general dental practices (regular attenders)

Clinical examination with 24-month recall showed no clear difference in dental caries: prevalence of root caries compared with clinical examination with 6-month recall; GRADE not reported.

Secondary (passive/secondhand) smoking exposure during childhood vs No secondary smoking exposure

Caries prevalence (early childhood caries) · Preschool children aged <=71 months (caries outcome assessed at 3-6 years)

Preschool children exposed to secondary smoking have higher odds of caries prevalence (OR 1.77), but the cross-sectional evidence is very uncertain (very low certainty).

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.
