Orthodontic treatment need vs No orthodontic treatment need

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

Orthodontic treatment need was associated with modestly higher odds of poor OHRQoL (OR 1.13, 95% CI 1.07-1.18; 3 studies; ungraded).

Intervention not reported

Dental caries in primary teeth · Children (primary dentition) worldwide

The pooled worldwide prevalence of dental caries in primary teeth in children was 46.2% (95% CI 41.6 to 50.8), with very high heterogeneity (I2=99.2%); certainty not graded.

Intervention not reported

Dental caries in permanent teeth · Children (permanent dentition) worldwide

In the Americas, the pooled prevalence of permanent-teeth caries in children was 48.9% (95% CI 37.6 to 60.3); certainty not graded.

LTF rs2073495 variant vs Reference allele/genotype

Dental caries · Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)

LTF rs2073495 showed no significant association with dental caries in a single study (OR 0.99, 95% CI 0.86 to 1.15; ungraded).

Intervention not reported

Dental caries in permanent teeth · Children (permanent dentition) worldwide

In Asia, the pooled prevalence of permanent-teeth caries in children was 58.8% (95% CI 53.4 to 64.0); certainty not graded.

Pulpotomy (full or partial) vs Pulpectomy

Tooth survival · Children with carious vital pulp exposure in primary incisors

Tooth survival was reported narratively in two trials and was not pooled.

Sealant (any type) vs no treatment

Arrest or reversal of noncavitated approximal carious lesions · Children and adults with noncavitated carious lesions on approximal surfaces (primary and permanent teeth)

Sealant may be more effective than no treatment for arrest or reversal of approximal carious lesions (RR 2.41, 95% CI 1.26 to 4.58; low certainty).

1 finding from 1 review

Colour clinical examination (visual shade categorization: yellow, light brown, dark brown, black) vs Hardness clinical examination (tactile texture categorization: soft, medium/leathery, hard)

Discriminant power for caries severity: effect size (f) for microbial load (log10 CFU) between lesion categories · Patients with dentine carious lesions (deciduous/permanent teeth; children and adults)

The weighted effect size favoured hardness (f=2.62) over colour (f=0.46) for discriminating microbial load, supporting hardness as the more reliable examination (ungraded).

38% SDF solution (applied biannually) vs 12% SDF solution (applied biannually)

Arrest of advanced cavitated carious lesions on any coronal surface · Preschool children with advanced cavitated carious lesions on any coronal surface (primary teeth)

38% SDF solution (applied biannually) was more effective than 12% SDF solution (applied biannually) for arrest or reversal of cavitated coronal carious lesions (RR 1.3, 95% CI 1.21 to 1.41; high certainty).
