Prior SDF application with a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Dental adhesives bonded to caries-affected dentin (in vitro)

Prior SDF followed by a rinsing step significantly increases adhesive bond strength to caries-affected dentin (MD -4.79 MPa favoring SDF, 95% CI -9.19 to -0.40; ungraded).

Early childhood caries (ECC) vs Caries-free primary dentition

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

Early childhood caries increases the likelihood of caries in permanent teeth roughly three-fold, but the certainty of evidence is very low (OR 3.22, 95% CI 2.80 to 3.71).

Baby-Led Introduction to SolidS (BLISS) vs Other models of complementary feeding

Overweight/obesity risk · Healthy children aged 6–24 months in Western industrialized countries

BLISS did not show a statistically significant reduction in overweight/obesity risk at 24 months (low certainty).

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Chronic herpes simplex infection prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in chronic herpes simplex infection between CLWH with and without ART (very low certainty).

SDF applied once (single application, no re-application) vs Other non/minimally-invasive treatment (ART or silver-fluoride varnish)

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

A single (one-time) SDF application did not significantly arrest caries (pooled ES -0.09, 95% CI -0.48 to 0.29; ungraded).

Resin-based fissure sealant vs Fluoride varnish

Caries incidence of first permanent molars (FPMs) · Schoolchildren aged 6-12 years with sound occlusal surfaces of the first permanent molars

Pit and fissure sealant and fluoride varnish showed no statistically significant difference in caries incidence of first permanent molars at 24 months (RR 0.65, 95% CI 0.31 to 1.38; I2=89%; not GRADE-rated).

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 LINC02905 (C8orf49) (chr8p23.1) · 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 LINC02905 (C8orf49) expression reached the TWAS threshold for ECC (p = 1.82e-8) but was flagged as a possible false positive (LD misspecification) and not further considered; ungraded.

Behaviour change / oral health promotion interventions delivered by non-dental professionals and health workers (nurses, midwives, health visitors, community health workers) vs control (no intervention/usual care/isotonic exercise)

Caries experience · Children (mean age newborn to ~5.2 years) and their parents/carers

Behaviour change interventions delivered by non-dental health workers produced a small-to-moderate, statistically significant reduction in caries experience at the tooth level (dmft SMD -0.34, 95% CI -0.54 to -0.13; 6 studies); the review judged the overall evidence to be of low quality (not GRADE-rated).

Silver diamine fluoride (SDF >=30%, i.e. 30% or 38%), applied annually or biannually vs No treatment or another non-invasive/minimally-invasive treatment (ART, sodium fluoride or silver-based varnish, or 12% SDF)

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

The pooled caries arrest rate with SDF (>=30%, applied annually/biannually) was 51.62% (622/1205 lesions arrested) at >=12 months follow-up.

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).

1 finding from 1 review

Prior SDF application without a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Dental adhesives bonded to caries-affected dentin (in vitro)

Only one study assessed SDF without a rinsing step on adhesive bonding to caries-affected dentin (Kucukyilmaz 2016, which reported impaired bond strength); no meta-analysis was possible, so no pooled estimate is available.

1 finding from 1 review

Combined antiretroviral therapy (cART) vs Monotherapy or dual antiretroviral therapy

Oral candidiasis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

cART was associated with a significantly lower prevalence of oral candidiasis than monotherapy or dual therapy (very low certainty).

1 finding from 1 review

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

Food preference · Children and adolescents (general population, aged under 20 years)

In crossover studies with binary outcomes, food marketing increased food preference (OR 3.49, 95% CI 2.03 to 6.22; ungraded).

1 finding from 1 review

Unfavourable oral hygiene and dietary habits (frequent sweet/sugar consumption; low toothbrushing frequency in early childhood) vs Favourable oral hygiene and dietary habits

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

Early-childhood oral hygiene and dietary habits show inconsistent associations with permanent-teeth caries, often losing significance after adjustment for past caries (2 studies; not pooled; not GRADE-rated).

1 finding from 1 review

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

Linear gingival erythema (WHO clinical stage 2) · Children or adolescents

No difference in linear gingival erythema between groups (pooled OR 1.00, 95% CI 0.06 to 16.19); the lesion was essentially absent in both groups.

Responsive complementary feeding (RCF) / other caregivers' feeding practices vs Other models of complementary feeding (traditional/non-responsive CF)

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

No eligible studies examined the influence of complementary feeding practices on later dental caries; this is an evidence gap.

Study-specific random forest classifier vs Caries versus healthy disease-state labels

Study-specific disease-state discrimination · Oral microbiome samples in 15 case-controlled studies

Bong-Soo 2017, Zhu 2018, and Jiang 2019 had mean AUC scores over 0.75; exact study-specific AUCs were not reported in text or readable figure labels.
