Caries experience measurement (mean D(M)FS, enamel lesions included) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries · European adolescents aged 12–19 years

Mean caries experience (DMFS) in subgroup 'Examination type: full-mouth' was 6.56 (95% CI 4.55 to 9.47; 12 studies).

Consumption of xylitol chewing gum by women (mothers) vs No chewing gum

Plaque · Adults and children (predominantly adults; one study in children), with natural dentition

Xylitol sugar-free gum significantly reduced plaque quantity versus no-gum/control (SMD -0.743, 95% CI -1.148 to -0.338), with high heterogeneity (I2 = 86.0%; ungraded).

Amalgam restoration vs Composite resin, compomer, conventional glass-ionomer cement, or resin-modified GIC (head-to-head RCT comparators)

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

Amalgam restorations in primary teeth showed a wide annual failure rate (1-28%) across 4 RCTs; the evidence is of low quality (high risk of bias; ungraded).

Caries distribution assessment (individual, tooth and surface levels) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Caries distribution (individual/tooth/surface level) · European adolescents aged 12–19 years

Caries distribution was skewed at individual, tooth and surface levels and too heterogeneous to meta-analyze (narrative synthesis of 11 studies; not GRADE-rated).

High-viscosity glass-ionomer cement (HVGIC) restoration (conventional restorative approach) vs Compomer, composite resin, or another HVGIC

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

High-viscosity GIC had a wide annual failure rate (2.9-25.6%) and was outperformed by compomer/composite in some trials (3 RCTs); low quality of evidence (ungraded).

Gum chewing (sugar-free) vs No chewing gum

Plaque · Adults and children (predominantly adults; one study in children), with natural dentition

Sugar-free chewing gum significantly reduced plaque quantity versus no-gum/control (SMD -0.778, 95% CI -1.167 to -0.390), with high heterogeneity (I2 = 86.6%) and no GRADE rating (ungraded).

Enamel caries quantification (DeS/DeT within total D(M)FS/D(M)FT) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Enamel caries proportion · European adolescents aged 12–19 years

Enamel caries made up about half of total caries experience (pooled proportion 0.50, 95% CI 0.39 to 0.65; 7 studies; higher in 12–15 than 16–19-year-olds; not GRADE-rated).

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).

Compomer (C) vs Amalgam, RMGIC, HVGIC, composite resin, bulk-fill composite resin, another compomer, or alternative caries management

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

Compomer had an annual failure rate of 0-14.7% (7 RCTs), comparable to amalgam/RMGIC/composite and better than high-viscosity GIC; low quality of evidence (ungraded).

38% silver diamine fluoride vs No treatment / other preventive agents (GIC, 5% NaF varnish)

Caries arrest · Children with dentine carious lesions (ICDAS 4-5) in primary teeth

A second meta-analysis reported odds ratios of 2.44 to 3.63 favouring 38% SDF over fluoride varnish/water for caries arrest (ungraded).
