A clinician must decide what ceramic coping and veneer material to prescribe based on the amount of tooth reduction possible and the desired esthetic outcome of the restoration. The purpose of this in vitro study was to compare the fracture strength of monolithic and bilayered lithium disilicate (IPS e.max) and zirconia (LAVA) crowns at clinically...

Denture teeth need to have sufficient wear-resistance in the partially edentulous patient with opposing natural teeth. Objectives: This study measures and compares the in vitro wear of denture teeth against human enamel. Methods: Mandibular molar denture teeth from 3 manufactures (see table) and extracted human teeth (control) were ground with...

Objectives: To measure and compare fracture strength of monolithic and bilayered LAVA and e.max crowns after load cycling. Methods: To compare fracture strengths of bilayered and monolithic LAVA zirconia/3M ESPE and e.max lithium disilicate/Ivoclar Vivadent crowns prepared with varying manufacturing techniques and thicknesses (table). A full crow...

Clinical placement of an LED light curing guide tip may be at a distance from the composite being polymerized. Objectives: To measure and compare depth of cure (DOC) and hardness of composite resin with 3 distances between the light guide tip and the composite produced by 5 LED lights. Methods: Specimens were prepared using 5 different curing l...

A new caries infiltrating resin was introduced which treats demineralized subsurface white-spot lesions (WSL). To be effective, this infiltrating resin must be color stable. Objectives: To measure the color stability and stain resistance of a caries infiltrant resin compared to enamel, WSL and composite. Methods: 160 extracted caries free human mol...

Objective: To measure and compare in vitro three body wear of 6 commercially available composites. Methods: Eight flat disc specimens of each composite (d=6mm/t=4mm) were prepared using a flexible mold following manufacturers' instructions, in two increments. Top layer was cured through a glass slide (Bluephase-IvoclarVivadent/1100mW/cm2). Specimen...

Flowable composite materials are less filled than traditional composites. Their composition allows ease of manipulation but makes these materials susceptible to increased polymerization shrinkage. Objective: To compare the polymerization shrinkage of one experimental and 7 commercially available flowable materials. Methods: Polymerization shrinkage...

Fracture strength of monolithic and bilayered LAVA and e. max lower molar crowns after load cycling was measured and compared. The study included three groups (n = 8) from LAVA zirconia and three groups from e. max lithium disilicate to compare influences of different layers, thicknesses and manufacturing techniques. Prefabricated anatomically desi...

OBJECTIVE: To measure and compare in vitro shear bond strength of one experimental and 2 commercially available self-adhesive cements to enamel, dentin, zirconia (Cercon), IPS e.max CAD and Paradigm C. METHODS: Ceramic blocks were wet ground with 320-grit SiC paper for 4mins (rotating the sample 900/min) and wet-finished with 0.5μ alumina slurry....

The success of pit and fissure sealants depends on its retention and seal. Objective: To measure the shear bond strength and microleakage of an experimental pit and fissure sealant used with phosphoric acid etchant and in a self etch mode to uncut enamel and compare it to 4 pit and fissure sealants. Methods: 120 extracted non-carious human molars w...
