Metal-free implant abutments (zirconia) vs Metal implant abutments (titanium)

Implant probing pocket depth (PPD) · Adults (18 years or older) with one missing tooth in the aesthetic zone needing an implant-supported single crown

Metal-free implant abutments (zirconia) showed no clear difference in implant probing pocket depth (PPD) compared with metal implant abutments (titanium); GRADE not reported.

High-viscosity glass-ionomer ART restorations vs Conventional treatment using RM-GIC

Restoration failure (permanent, mature teeth) · Adults with root caries in permanent (mature) teeth

ART using H-GIC showed no clear difference in restoration failure (permanent, mature teeth) compared with conventional treatment using RM-GIC (with local anaesthetic); GRADE not reported.

Metal-free implant-supported FDPs (zirconia-toughened alumina; In-Ceram Zirconia) vs Metal-free implant-supported FDPs (yttria-stabilized tetragonal zirconia; Denzir)

Bridge failure · Adults (18 years or older) needing an implant-supported fixed dental prosthesis in the posterior region

Metal-free implant-supported single crowns (zirconia veneered with feldspathic ceramic) vs Metal-ceramic implant-supported single crowns

Aesthetics · Adults (18 years or older) with one missing tooth in the aesthetic zone needing an implant-supported single crown

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed primary surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

Fluoride supplementation (tablets, drops, lozenges or chewing gum) showed no clear difference in decayed primary surfaces at 3 years compared with placebo or no treatment; GRADE not reported.

ART using glass ionomer cement (GIC) vs Amalgam restoration

Restoration failure (permanent, immature teeth) · Children and adolescents with dental caries (primary teeth and permanent immature teeth)

ART using glass ionomer cement (GIC) led to higher restoration failure (permanent, immature teeth) compared with conventional treatment using amalgam; GRADE not reported.

Metal-free tooth-supported FDPs (pressed veneering ceramic) vs Metal-free tooth-supported FDPs (layered veneering ceramic)

Bridge failure · Adults (18 years or older) needing a three-unit tooth-supported fixed dental prosthesis
1 finding from 1 review

Resin-based fissure sealant (2nd/3rd/4th generation) vs No sealant (control/no treatment)

Dentine caries in permanent molars (24 months) · Children and adolescents (general population, aged under 20 years)

Resin-based fissure sealant (2nd/3rd/4th generation) probably leads to lower dentine caries in permanent molars (24 months) compared with no sealant (control/no treatment) (moderate certainty).

Metal-free FDPs (lithium disilicate) vs Metal-ceramic FDPs

Bridge failure · Adults (18 years or older) needing a three-unit fixed dental prosthesis (FDP)

It is very uncertain whether metal-free FDPs (lithium disilicate) changes bridge failure compared with metal-ceramic FDPs (very low certainty).

ART using composite resin vs Conventional treatment using composite resin

Restoration failure (primary dentition) · Children with carious primary teeth

It is very uncertain whether ART using composite resin changes restoration failure (primary dentition) compared with conventional treatment using composite resin (very low certainty).
