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).

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

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

About 25% of children with caries in LMICs were of high SES (pooled prevalence 0.245, 95% CI 0.162 to 0.339; 5 studies; not GRADE-rated).

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).

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).

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.

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

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

In symptomatic irreversible pulpitis, pooled pulpotomy success was 84% (95% CI 72-92%); not significantly different from asymptomatic (z=-1.34, p=0.18); ungraded.

Enamel caries in primary dentition (at 5 years) vs Caries-free primary dentition

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

Enamel caries in the primary dentition is associated with about 1.6 times higher odds of dentinal caries in permanent teeth (single study; not GRADE-rated).

Common genetic variants genome-wide (GWAS; ~3.9 million SNPs with MAF > 5%) vs ECC-unaffected children (per-allele case-control association)

Early childhood caries (ECC) - association at lead SNP rs74470773 (3:33958083; nearest gene(s) PDCD6IP) · Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)

The common variant rs74470773 near PDCD6IP showed suggestive (not genome-wide significant) association with ECC (Z = -4.589, p = 4.46e-6); genetic association, ungraded.

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

Caries experience · Children and adolescents (<18 years) living with HIV (CLWH)

ART was not associated with a significant difference in dental caries experience among CLWH (very low certainty).

1 finding from 1 review

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

Persistent parotid enlargement prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

No significant difference in persistent parotid enlargement between ART regimens (very low certainty).

Sugary drinks/sweets consumption vs Children without dental caries

Dental caries (association with sugary drinks/sweets consumption) · Children (deciduous and/or permanent dentition) in low- and middle-income countries

Sugary drinks/sweets consumption was associated with about twice the odds of dental caries in LMIC children (OR 2.04, 95% CI 1.59 to 2.60; 7 studies; not GRADE-rated).

1 finding from 1 review

Amalgam vs Preformed metal crown (PMC)

Treatment failure (annual failure rate) · Children with carious primary molars treated by pulpotomy (vital pulp therapy)

Preformed metal crowns had a low annual failure rate (2.4%) in primary molars after pulpotomy, lower than amalgam in the same trial (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).
