Populations in countries with a lower Human Development Index (high category, HDI <0.800) vs Populations in countries with a higher Human Development Index (very high, HDI >=0.800)

Caries experience (mean DMFT) · Adults aged 19-60 years

Pooled caries experience (DMFT) was similar in very-high-HDI and high-HDI countries, and meta-regression found no significant association between national HDI and DMFT; ungraded observational evidence with very high heterogeneity.

Biodentine vs Tempophore

Radiological failure · Children with extensive decay involving the dental pulp in primary teeth

Biodentine showed no clear difference in radiological failure compared with tempophore; GRADE not reported.

Radiographic caries detection (bitewing radiography) vs Reference standard (histological validation or cavity/lesion opening; advanced = cavitated/dentin-involved lesions, all = enamel-confined initial lesions also counted)

Negative LR for detecting all (initial and advanced) proximal caries · Proximal surfaces of permanent molars (demonstrated in 12-14 year-olds; underlying diagnostic accuracy studies, mostly in vitro)

In the meta-analysis tailored to Egypt, the negative lr of radiographic detection for all (initial and advanced) proximal caries was 0.65 (95% CI 0.57 to 0.74) (ungraded).

Fluoride in dentifrice vs no treatment

Caries increment, surface index D(M)FS · Children or adolescents

In the illustrative network meta-regression the SMD for caries increment differed between fluoride in dentifrice and no treatment at every displayed randomization year; certainty was not graded.

Low income vs High income

Mean number of decayed teeth (mean DT) · Adults aged 25 years and older in Australia, Canada, New Zealand, and the United States

Across four countries, low versus high income differed by 0.44 decayed teeth in mean number of decayed teeth (random-effects meta-analysis; I2=76.4%).

Populations with low socioeconomic status (>=22.4% of the population with low SES) vs Populations with higher socioeconomic status (<22.4% of the population with low SES)

Caries experience (mean DMFT) · Adults aged 19-60 years

Populations with a higher proportion of people with low socioeconomic status had higher caries experience (pooled DMFT 15.99 vs 5.50), and meta-regression associated low SES with higher DMFT (about 10.35 more DMFT per unit; p=0.050); ungraded observational evidence.

Zinc oxide and eugenol (ZOE) vs Zinc oxide and propolis (ZOP)

Outcome not reported · Children with extensive decay involving the dental pulp in primary teeth

The review found no eligible studies for this question.

Conventional restorative treatment with compomer vs Other network treatments

Treatment success rate · Primary teeth with dentin caries lesions on occlusal surfaces

CRT with compomer ranked first for treatment success in the occlusal-surface network (low certainty).

1 finding from 1 review

Fluorides combined with CPP-ACP vs Fluorides alone (monotherapy)

Visual inspection scores · Patients with early caries lesions in permanent teeth (non-fluoridated water area)

Two trials reported visual inspection scores but could not be pooled (different criteria, missing standard deviations) and gave inconsistent findings, so no quantitative conclusion could be drawn.

Human Development Index (HDI) vs Not applicable

Dental caries · Adult participants in 25 meta-regression studies

The Model 1 adjusted meta-regression coefficient for quantitative HDI was -42.94101.

3 findings from 1 review

Secondary education vs University education

Mean number of decayed teeth (mean DT) · Adults aged 25 years and older in Australia, Canada, New Zealand, and the United States

In Canada, secondary versus university education differed by 0.7 decayed teeth in mean number of decayed teeth.

Self-etch adhesive + acetone-based total-etch adhesive vs Acetone-based total-etch adhesive

Clinical failure · Children with extensive decay involving the dental pulp in primary teeth

It is very uncertain whether self-etch adhesive + acetone-based total-etch adhesive changes clinical failure compared with acetone-based total-etch adhesive (very low certainty).

Postnatal passive tobacco exposure (secondhand/household smoke in infancy) vs No passive tobacco exposure (non-exposed children)

Dental caries in permanent teeth · Children and adolescents with permanent dentition

Postnatal (infancy) tobacco exposure is associated with higher odds of caries in permanent dentition (pooled OR 1.30, 95% CI 1.25 to 1.34; 9 studies; no heterogeneity); certainty not graded.
