Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of NRAD1 (LINC00284) (chr13q14.11) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted NRAD1 (LINC00284) expression reached the TWAS threshold for ECC (p = 1.69e-6) but was flagged as a possible false positive (LD misspecification) and not further considered; ungraded.

Silver diamine fluoride (SDF; 30% or 38%) vs Atraumatic restorative treatment (ART)

Caries arrest · Children (age 1-10 years) with active cavitated dentin caries lesions in primary molars

SDF was not significantly better than ART at arresting caries (pooled ES 0.05, 95% CI -0.42 to 0.51; ungraded).

Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression)

Early childhood caries (ECC) - association with genetically predicted expression of TAS2R31 (chr12p13.2) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

Genetically predicted expression of TAS2R31 was suggestively associated with ECC in the TWAS (p = 1.04e-5); genetic association, ungraded.

Composite resin vs Compomer, glass-ionomer/RMGIC, amalgam, or glass carbomer

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years

Composite resin (hybrid 0-19.5%; bulk-fill 0-16.9%) performed comparably to or better than most alternatives across 11 RCTs; evidence is of low to unclear quality (ungraded).

Bio-active restorative materials vs Any restorative material or technique

Not applicable (no eligible studies) · Children with carious primary teeth (no pulp therapy)

No eligible RCTs assessed new bio-active restorative materials in carious primary teeth; this is an evidence gap identified by the review.

Pulpotomy (full or partial) vs None (single-arm pooled success proportion)

Overall success (composite of clinical and radiographic success) · Human permanent teeth with irreversible pulpitis and open (immature) root apex due to carious pulp exposure

In open-apex teeth, pooled pulpotomy success was 95.8% (95% CI 81-99%); significantly higher than closed apex (z=2.33, p=0.02); ungraded.

Living with HIV and undergoing antiretroviral therapy (ART/HAART) vs Healthy HIV-negative controls

Oral candidiasis (WHO clinical stage 3) · Children or adolescents

CLWH on ART had markedly higher prevalence of oral candidiasis than healthy controls (pooled OR 16.94, 95% CI 5.06 to 56.70).

Responsive / non-responsive complementary feeding (RCF/NRCF) vs Other models of complementary feeding

Choking · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No systematic reviews or studies assessed choking risk for RCF or NRCF (only BLW/BLISS); this is an evidence gap.

1 finding from 1 review

Atraumatic restorative treatment vs Conventional treatment with local anaesthesia

Discomfort associated with the procedure · People with dental caries in primary teeth (mainly children)

The reported estimate for discomfort with ART versus conventional treatment was inconclusive (ungraded).

1 finding from 1 review

Food marketing exposure or greater marketing power vs No, less, or less powerful food marketing

Dental caries · Children and adolescents (general population, aged under 20 years)

Across two studies, 50% showed any association of potential public health harm for dental caries (very low certainty).

1 finding from 1 review

Machine-learning algorithms for dental caries detection vs Different machine-learning algorithms for caries prediction

Post-Streptococcus mutans prediction accuracy · Dental images of human beings

The review reported 99% accuracy for post-Streptococcus mutans prediction in Javed et al. (Ungraded).

Baby-led weaning (BLW) / BLISS vs Traditional complementary feeding (TCF)

Choking · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No significant difference in choking risk was found between BLW/BLISS-fed and traditionally fed infants (ungraded).

Food and nonalcoholic beverage marketing (exposure) vs No, less, or less powerful food marketing

Body weight / BMI · Children and adolescents (general population, aged under 20 years)

Evidence on food marketing and body weight is very uncertain (very low certainty); a single study found no association.

Dental caries vs Caries-free status

Beta diversity and community composition · Participants in oral 16S rRNA caries microbiome studies

Beta-diversity matrices showed statistically significant ADONIS results, while clustering by study and 16S region was also observed; no pooled effect estimate was reported.
