Light-cured resin-modified glass ionomer cement vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 1 year in permanent teeth, secondary caries did not differ significantly between RMGIC and GIC (RR 1.82, 95% CI 0.45-7.28; low certainty).

ART sealant using high-viscosity glass ionomer (press-finger technique) vs Resin-based sealant

Development of carious lesions on sealed occlusal pits and fissures · Children with fully erupted permanent first molar teeth (mean age about 6 to 8 years)

At 48 months, no statistically significant difference was found between HVGIC and resin-based sealants (RR 0.62, 95% CI 0.31 to 1.21); evidence ungraded and at high risk of bias.

Glass ionomer cement vs Resin composite restoration

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 2 or more years in permanent teeth, GIC probably reduces secondary caries versus resin composite (RR 0.50, 95% CI 0.28-0.91; moderate certainty).

38% silver diamine fluoride vs Glass ionomer cement (GIC) plus fluoride varnish

Caries prevention (preventive fraction, SDF vs GIC+5% fluoride varnish) · intellectually disabled individuals with caries in permanent posterior teeth

SDF had a 45% preventative fraction versus glass ionomer cement plus fluoride varnish; no pooled estimate or GRADE rating was reported.

Glass ionomer-based sealant vs Resin-based sealant

Caries occurrence on sealed teeth · Sealed permanent teeth

Glass-ionomer and resin-based fissure sealants showed no statistically significant difference in caries occurrence on sealed permanent teeth at 12 months (no GRADE rating).

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.

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

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

Ion-releasing GIC restorations may have little or no difference in secondary caries at 1 year (low certainty).

38% SDF (indirect pulp capping) vs Resin-modified glass ionomer cement (RMGIC)

Secondary prevention of caries · children with deep occlusal carious lesions in permanent molars

No significant difference in secondary caries prevention was reported; no effect estimate or GRADE rating was reported.

38% SDF plus potassium iodide (KI) (indirect pulp capping) vs Resin-modified glass ionomer cement (RMGIC)

Secondary prevention of caries · children with deep occlusal carious lesions in permanent molars

No significant difference in secondary caries prevention was reported; no effect estimate or GRADE rating was reported.

ACTIVA bioactive restorative material vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 1 year in permanent teeth, the effect of ACTIVA versus GIC on secondary caries is very uncertain (RR 22.80, 95% CI 0.89-584.17; very low certainty).

1 finding from 1 review

Composite resin vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 1 year in permanent teeth, resin composite showed no statistically significant difference in secondary caries versus GIC (RR 3.05, 95% CI 0.95-9.79; low certainty).

2 findings from 1 review

Compomer (Dyract) vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 2 or more years in permanent teeth, the effect of compomer versus GIC on secondary caries is very uncertain (RR 3.20, 95% CI 0.59-17.33; very low certainty).

Fluoride-containing amalgam (FAAG) vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 2 or more years in permanent teeth, secondary caries did not differ significantly between fluoride-containing amalgam and GIC (RR 0.95, 95% CI 0.45-2.00; low certainty).

Amalgam (AAG) vs Glass ionomer cement (GIC)

Secondary caries · Patients requiring dental restoration; permanent teeth

Over 2 or more years in permanent teeth, amalgam had a higher risk of secondary caries than GIC (RR 1.79, 95% CI 1.04-3.09; low certainty).
