Self-assembling/remineralizing peptide (e.g., P11-4, PAA-PASP) 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 Self-Etch adhesive + chemical ACAD protocol network, Peptide vs Fluorine showed no significant difference in 24 h bond strength (MD 2.131, 95% CI -2.213 to 6.475; Low certainty).

AI algorithms (predominantly CNN/deep learning) as index test vs Dental expert / visual-tactile clinical assessment (reference standard)

Sensitivity · Patients undergoing dental caries detection on dental images (teeth/surfaces across imaging modalities)

AI algorithms have high pooled sensitivity (0.85) for detecting dental caries; ungraded, with very high heterogeneity (I2>95%) and evidence of publication bias.

Calcium phosphate agent (e.g., CPP-ACP, Ca/P-PILP, niobophosphate) 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 Etch-and-Rinse adhesive + chemical ACAD protocol network, Calcium Phosphate vs Calcium showed no significant difference in 24 h bond strength (MD 0.596, 95% CI -7.289 to 8.482; Low certainty).

Partial pulpotomy with one additional day before permanent restoration vs Partial pulpotomy with one fewer day before permanent restoration

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

Each additional day before permanent restoration was associated with a 0.088% decrease in success in meta-regression.

Iron deficiency anemia (IDA) vs Children without anemia (non-anemic)

Dental caries · Children or adolescents

Children with iron deficiency anemia are over three times more likely to have dental caries than non-anemic children (OR 3.64, 95% CI 2.45 to 5.40; moderate certainty).

Conventional restoration vs Atraumatic restorative treatment (ART)

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

At 12 months, conventional restorations had significantly higher treatment success than ART (OR 2.10; moderate certainty).

Replacement of the defective restoration vs Repair of the defective restoration

Composite: Preference for replacement over repair - Scenario 2: loss of dental hard substance adjacent to the restoration · Dentists managing a defective direct resin composite restoration (posterior occlusal Class I; standardized vignette of a 30-year-old,…

For a defective composite restoration with loss of dental hard substance adjacent to the restoration, surveyed dentists most often preferred repair over replacement (pooled RR 0.75; p = 0.004); ungraded.

Composite: Preference for replacement over repair - Scenario 5: open margin · Dentists managing a defective direct resin composite restoration (posterior occlusal Class I; standardized vignette of a 30-year-old,…

For a defective composite restoration with open margin, surveyed dentists most often preferred replacement over repair (pooled RR 3.93; p < 0.001); ungraded.

Higher drinking-water fluoride exposure vs Null / lowest drinking-water fluoride exposure (reference)

Risk of fragility fractures · Females (all ages)

In females, fragility-fracture risk was U-shaped: lowest ~0.4 mg/L, rising above 0.9 mg/L (RR 0.84 at 0.34, 1.00 at 0.9, 1.13 at 1.1 mg/L vs null); ungraded.
