Clinical evaluation of ceramic inlays and onlays fabricated with two systems: 12-year follow-up.

Objectives: The aim of this study was to evaluate the 12-year clinical performance of sintered (Duceram, Dentsply-Degussa, Dentsply International Inc., PA, USA)-D and pressable (IPS Empress, Ivoclar-Vivadent, Schaan, Leichtenstein)-IPS ceramic inlay and onlay restorations.

Methods: Eighty-six restorations were placed in 35 patients with a median age of 33 years by a single operator.

Effect of resin-modified glass-ionomer cement lining and composite layering technique on the adhesive interface of lateral wall.

Unlabelled: Interface integrity can be maintained by setting the composite in a layering technique and using liners.

Objective: The aim of this in vitro study was to verify the effect of resin-modified glass-ionomer cement (RMGIC) lining and composite layering technique on the bond strength of the dentin/resin adhesive interface of lateral walls of occlusal restorations.

Material And Methods: Occlusal cavities were prepared in 52 extracted sound human molars, randomly assigned into 4 groups: Group 2H (control) - no lining + two horizontal layers; Group 4O: no lining + four oblique layers; Group V-2H: RMGIC lining (Vitrebond) + two horizontal layers; and Group V-4O: RMGIC lining (Vitrebond) + four oblique layers.

Conservative approach to restore the first molar with extensive destruction: A 30-month follow-up.

The available options for restoring multiple surface cavities are: amalgam, composite resin, or indirect restorations. Adhesive system and intradentinal pin-retained composite resin restorations should have a similar performance to pin-retained amalgam, regarding resistance to support occlusal forces. Polymerization shrinkage is a major concern when performing direct posterior composite resin restorations and the incremental insertion technique can provide less stress and outstanding margin behavior.
