Metal-reinforced glass-ionomer cement (MRGIC) restoration vs Conventional GIC

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

Metal-reinforced GIC had a high annual failure rate (29.9%) in a single RCT; low quality of evidence (ungraded).

Silver diamine fluoride (SDF) plus fluoride varnish vs Atraumatic restorative treatment + fluoride varnish (ART+FV)

Oral health-related quality of life · Children with dental caries

SDF plus fluoride varnish did not significantly differ from ART plus fluoride varnish for oral health-related quality of life (MD 0.16, 95% CI -0.1 to 0.42; ungraded).

Socioeconomic status category vs Not applicable (single-group prevalence)

Low SES prevalence (among children with caries) · Children with dental caries (deciduous and/or permanent dentition) in low- and middle-income countries

About 36% of children with caries in LMICs were of low SES (pooled prevalence 0.359, 95% CI 0.167 to 0.578; 4 studies; not GRADE-rated).

ART/HAART duration <3 years vs ART/HAART duration >=3 years

Oral candidiasis · Children and adolescents living with HIV on ART/HAART

Oral candidiasis prevalence differed by ART duration (OR 17.93, 95% CI 3.69 to 83.12).

Multiple-surface ART restoration using high-viscosity glass ionomer vs Single-surface ART with high-viscosity GIC

Restoration survival · Children with decayed primary molar teeth

Multi-surface ART/HVGIC restorations had lower reported survival (49% at 3 years) than single-surface restorations (ungraded).

1 finding from 1 review

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

Periodontal disease prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

ART was not associated with a significant difference in periodontal disease prevalence among CLWH (very low certainty).

Dental caries vs Caries-free status

KEGG pathway associations · Participants in oral 16S rRNA caries microbiome studies

Phosphonate and phosphinate metabolism and glyoxylate and dicarboxylate metabolism had the lowest reported adjusted P values (0.04); no pooled effect estimate was reported.

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

Kaposi's sarcoma prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

Kaposi's sarcoma was significantly more prevalent in treatment-naive CLWH than in those on ART (very low certainty).

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

Choking · Healthy children aged 6–24 months in Western industrialized countries

No statistically significant difference in choking events between BLW/BLISS and TCF was reported.

1 finding from 1 review

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

Kaposi's sarcoma prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in kaposi's sarcoma between ART regimens (very low certainty).

1 finding from 1 review

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

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

Food marketing showed no clear association with food purchasing by or for children (very low certainty).

1 finding from 1 review

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

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

ART was associated with lower oral candidiasis prevalence.

1 finding from 1 review

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

Recurrent oral ulceration prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in recurrent oral ulceration between CLWH with and without ART (very low certainty).

1 finding from 1 review

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

Hypertension (later in life) · 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 hypertension; this is an evidence gap.

Adaptive dragonfly algorithm with neural-network classifier vs KNN or SVM (not disaggregated in source)

Accuracy advantage in test case 2 · Dental images of human beings

The review reported a 52% accuracy advantage in Patil test case 2 (Ungraded).

Dental caries assessment (WHO/clinical diagnostic criteria; caries = DMFT>0) vs None (descriptive prevalence; random-effects pooled proportion)

Dental caries prevalence · Children (deciduous and/or permanent dentition) in low- and middle-income countries

About 39% of children in LMICs had dental caries (pooled prevalence 0.387, 95% CI 0.284 to 0.495; 11 studies; very high heterogeneity I2=99%; not GRADE-rated).
