Electronic cigarette use vs Non-smokers (non-users)

Oral candidiasis prevalence · Adult e-cigarette (ENDS) users (general oral health; predominantly natural dentition)

Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Osteoporosis with pathological fracture · European-ancestry adults

In multivariable MR, genetically predicted dental caries (DMFS) had no significant causal effect on osteoporosis with pathological fracture (OR 1.279, not significant).

Hydroxyapatite (e.g., nano-HAp) vs Calcium-based agent

Immediate (24 h) resin-dentin bond strength (MPa) · Artificial caries-affected dentin (ACAD) in extracted permanent human teeth (in vitro)

In the Self-Etch adhesive + chemical ACAD protocol network, HAp vs Calcium showed no significant difference in 24 h bond strength (MD -1.792, 95% CI -7.415 to 3.831; Low certainty).

Dental treatments, care, and services (the decision context) vs No comparator

Out-of-pocket payment / cost as a factor of choice · (Potential) patients with freedom of choice regarding dental treatments, including parents and caregivers deciding for children or…

Out-of-pocket payment (cost) was the most frequently reported factor influencing patients' dental treatment decisions (N=136 articles; ungraded).

Flavonoids (e.g., quercetin, proanthocyanidin) vs Fluoride agent (e.g., NaF/SDF/KF/CaF2)

Immediate (24 h) resin-dentin bond strength (MPa) · Artificial caries-affected dentin (ACAD) in extracted permanent human teeth (in vitro)

In the Etch-and-Rinse adhesive + biological ACAD protocol network, Flavonoids vs Fluorine showed no significant difference in 24 h bond strength (MD 4.241, 95% CI -2.652 to 11.135; Moderate certainty).

Full pulpotomy vs Partial pulpotomy

Overall success (composite of clinical and radiographic success) · Adults aged 18 years or older with mature permanent teeth and carious pulp exposure

The three-study meta-analysis found no significant difference between full and partial pulpotomy after 1 year.

Cleft lip and/or palate (CL/P) vs Healthy controls without cleft

Gingival index (GI) · Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)

Persons with orofacial cleft have a higher gingival index than healthy controls (MD 0.15, 95% CI 0.11 to 0.19; low certainty).

Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Osteoporosis · European-ancestry adults

In multivariable MR (adjusted for periodontitis), higher genetically predicted dental caries (DMFS) causally increased osteoporosis risk (OR 1.165, moderate evidence).

Anticaries vaccine or antibody (DNA, recombinant protein, nanoparticle-adjuvanted, live-vector, plant-based, or passive IgY immunization) targeting S. mutans vs Control (unvaccinated / empty vector / PBS / placebo animals)

Streptococcus mutans colonization reduction (narrative; no CFU data reported) · Animal caries models (mice, rats, hamsters) challenged/colonized with Streptococcus mutans; one transgenic-plant antigen-expression system

Anticaries vaccines produced a sustained reduction in Streptococcus mutans colonization on teeth in animal models (ungraded narrative synthesis; no pooled estimate).

Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Bone mineral density in forearm · European-ancestry adults

Genetically predicted dental caries (DMFS) had no causal effect on forearm BMD.

Obesity or overweight (higher BMI, mostly WHO BMI ≥25/≥30; 2 studies used waist circumference) vs Normal Weight or Non‐Obese

Dental caries · Adults (≥18 years)

After adjustment for confounders, obesity/overweight was not associated with dental caries (OR 1.00, 95% CI 0.89 to 1.12; ungraded).

Ion-releasing restorations (IRR): RMGIC, HVGIC, GIC, compomer/PMRC, giomer vs Composite resin (CR), including bulk-fill composite

Adequate marginal adaptation · Children receiving dental restorations (aged 4-11 years; primary teeth; Class I/II/V cavities)

No significant difference between IRR and CR in marginal adaptation (high certainty).

Hall technique vs Sealing

Treatment success (caries lesion arrest or restoration survival) · Children (aged 3-11 y) with cavitated caries lesions in primary teeth

At 12 months, the Hall technique had significantly higher treatment success than sealing (OR 13.93; moderate certainty).

Mineral trioxide aggregate (MTA) vs Calcium hydroxide (CH)

Postoperative pain (patient-reported) · Vital permanent teeth (mature or immature) with deep or extremely deep caries and asymptomatic pulp or reversible pulpitis, undergoing…

The effect of material choice (MTA vs CaOH) on postoperative pain is unclear: two small studies used different methods and reported contradictory results, so no meta-analysis was performed (ungraded).
