| Articles | Cases treated | Parameters evaluated | Surface treatments | Conclusions |
|---|---|---|---|---|
| Derand et al. 2000 | 3 cements on composite cylinders (n=10) | Shear bond strength after water storage for 5h, 1d, 7dd, 2mm | Sandblasting with Al2O3 at 250μm, sandblasting with Al2O3 at 50μm, etching with hydrofluoric acid at 37%, roughening with diamond burr | Resin cements show higher bond values. Surface treatments don’t provide significant benefits. |
| Wegner et al. 2000 | 5 cements on plexiglass (n=16) | Shear bond strength after water storage 3dd, 2yy + thermocycling at 5–55°C x 37500 cycles | Sandblasting with Al2O3 at 50μm, silanization | Bis-GMA-based cements are not stable. Cements containing MDP in association with sandblasting give better results |
| Ernst et al. 2005 | 8 cements on dentin (n=10) | Axial displacement after thermocycling at 5–55°C x 5000 cycles | Silanization | There aren’t significant differences in bond strength of different cements. Silane doesn’t improve the adhesion |
| Piwowarczyk et al. 2005 | 11 cements on epoxy resin (n=20) | Shear bond strength after 30’ from cementation and after water storage for 14dd + thermocycling at 5–55°C x 1000 cycles | Sandblasting with Al2O3 at 100μm, silanization | Zinc phosphate and glass-ionomer cements don’t give stable adhesion. Cements containing MDP show higher and more stable adhesion |
| Palacios et al. 2006 | 3 cements on dentin (n=12) | Axial displacement after thermocycling at 5–55°C x 5000 cycles | Sandblasting with Al2O3 at 50μm | All 3 cements are able to provide a sufficient retention at the coping, without requiring surface treatments beyond sandblasting |
| Luthy et al. 2006 | 5 cements on stainless steel (n=30) | Shear bond strength after water storage 2dd or thermocycling at 5–55°C x 10000 cycles | Sandblasting with Al2O3 at 110μm | All cements lose resistance after thermocycling except those containing MDP |
| Wolfart et al. 2007 | 2 cements on plexiglass (n=20) | Shear bond strength after water storage for 3dd or 150dd + thermocycling at 5–55°C x 37500 cycles | Sandblasting with Al2O3 at 50μm | Cements containing MDP + sandblasting provide greater and lasting adhesion |
| Re et al. 2008 | 2 cements on stainless steel (n=40) | Shear bond strength after water storage for 7dd | Sandblasting with Al2O3 at 110μm, sandblasting with Al2O3 at 50μm, silanization | Cements containing MDP provide greater adhesion and are less influenced by the surface treatments. Sandblasting improves significantly adhesion |
