Maternal education attainment vs Children without dental caries

Dental caries (association with no formal maternal education) · Children (deciduous and/or permanent dentition) in low- and middle-income countries

No formal maternal education showed a non-significant trend toward higher odds of dental caries (OR 1.34, 95% CI 0.76 to 2.36; 3 studies; not GRADE-rated).

Composite resin with etch-and-rinse (total-etch) adhesion vs Composite resin with self-etch adhesion (same universal adhesive)

Treatment failure (annual failure rate) · Children with moderately deep dentine caries in primary molars, no pulp therapy

Etch-and-rinse adhesion failed more than self-etch (19.5% vs 7.0% annual failure) in one RCT; low quality of evidence (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).

Composite strip crown (CSC) with a post (microhybrid composite resin, Amelogen) vs Post type: composite post (CP) vs fibre post (FP) vs reverse metal post (RMP)

Treatment failure (annual failure rate) · Children with severely decayed maxillary primary incisors treated by pulpectomy (non-vital pulp therapy)

Composite strip crowns with composite posts had a low annual failure rate (2.3%) in maxillary primary incisors after pulpectomy (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

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

Dental development / dental age (mineralization chronology) · Children or adolescents

No significant overall difference in dental development between CLWH on ART and healthy controls (three studies, narrative synthesis).

Resin-modified glass ionomer cement for bonding orthodontic brackets vs Resin composite restoration

Restoration failure · Children with carious primary teeth

No comparative effect estimate was reported; both arms had 16% failure.

Ion-releasing restoration, glass ionomer-based (conventional GIC, HV-GIC, RMGIC, glass hybrid) vs Resin composite restoration

Marginal adaptation (unacceptable marginal adaptation) · Patients with permanent dentition in need of restorations (all cavity types: Black's Class I, II, V, and non-carious cervical lesions)

Across follow-up periods, there was no statistically significant difference in unacceptable marginal adaptation between GIC and resin composite restorations.

Caries assessment at dentine threshold (cavitation into dentine) vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · European adolescents aged 12–19 years

Caries prevalence at the dentine threshold was about 56% (pooled 0.56, 95% CI 0.43 to 0.68; 15 studies; not GRADE-rated).

Glass ionomer-based sealant vs No sealant (control/no treatment)

Development of >=1 new carious lesion (caries incidence) · Children with caries-free primary first molars (with or without caries on other teeth), aged 1-5 years (paediatric clinic/dental school,…

Glass ionomer-based sealant may leads to lower development of >=1 new carious lesion (caries incidence) compared with no sealant (low certainty).

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

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

In asymptomatic irreversible pulpitis, pooled pulpotomy success was 91.3% (95% CI 80-96.5%); ungraded.

Caries assessment at enamel threshold vs None (descriptive prevalence review; subgroup analyses by urban/rural status, country and year)

Dental caries prevalence · European adolescents aged 12–19 years

Enamel-threshold caries prevalence in subgroup 'Region: non-Scandinavian' was 0.74 (95% CI 0.53 to 0.96; 11 studies).

Pulpotomy with Biodentine vs Pulpotomy with Calcium Enriched Mixture (CEM)

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

Biodentine had a significantly higher pulpotomy success rate than CEM (indirect comparison; numeric estimate not available); ungraded.

Pulpotomy with mineral trioxide aggregate (MTA) vs Pulpotomy with Calcium Enriched Mixture (CEM)

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

MTA and CEM did not differ significantly in pulpotomy success (indirect comparison); ungraded.

Cleft lip and/or palate (CL/P) vs No cleft lip and/or palate (non-CL/P)

Early childhood caries experience (mean dmft) · Children in the primary dentition with non-syndromic cleft lip and/or palate (CL/P) and comparable children without CL/P

In the combined primary and mixed dentition, there was no evidence of a difference in caries experience between children with and without CL/P (SMD 0.09, 95% CI -0.59-0.76; 5 studies; ungraded).

Transillumination and OCT vs Reference standard (histology, excavation, or enhanced visual examination)

Specificity for detection of enamel caries · Asymptomatic children or adults suspected of enamel caries (clinical studies); extracted teeth (in vitro studies)

Transillumination and OCT had a summary specificity of 0.82 (95% CrI 0.68, 0.91) for detecting enamel caries; low certainty.

CD4+ T-cell count below 250 cells/mm3

HIV-related oral lesions · Children living with HIV receiving ART

One reported study did not show a clear difference in HIV-related oral lesions for children with CD4+ T-cell counts below 250 cells/mm3.

Prior application of silver diamine fluoride (SDF), with or without a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Dental adhesives/resin composite bonded to dentin (in vitro), sound or caries-affected

Prior SDF application significantly reduces the immediate bond strength of adhesives to dentin overall (MD 7.12 MPa favoring untreated dentin, 95% CI 1.38 to 12.85; ungraded), with very high heterogeneity (I2=98%).
