Comparison of the light transmission of new generation monolithic zirconia materials and lithium disilicate.

Purpose: To compare the effects of different thicknesses of ceramic veneering on the light transmission of various monolithic zirconia and lithium disilicate materials used in esthetic restorations.

Methods: Zirconia (i.e.

Influence of anodized titanium abutment backgrounds on the color parameters of different zirconia materials.

Purpose: To characterize the color outcome on different zirconia types of various colored titanium backgrounds produced with a newly developed anodized technique.

Methods: Blue, green, pink and gold-colored titanium backgrounds were produced via different anodization voltage values. Non-anodized grey colored titanium was used as a control.

Effect of different surface treatments on the shear bond strength of luting cements used with implant-supported prosthesis: An study.

Purpose: The aim of this study was to investigate the shear bond strength of luting cements used with implant retained restorations on to titanium specimens after different surface treatments.

Materials And Methods: One hundred twenty disc shaped specimens were used. They were divided into three groups considering the surface treatments (no treatment, sandblasting, and oxygen plasma treatment).

Fracture strengths of endocrown restorations fabricated with different preparation depths and CAD/CAM materials.

The objectives of this study were to compare the fracture strength of endocrown restorations fabricated with different preparation depth and various CAD/CAM ceramics, and to assess the fracture types. Endodontically treated 100 extracted human permanent maxillary centrals were divided into two preparation depth groups as short (S: 3-mm-deep) and long (L: 6-mm-deep), then five ceramic subgroups, namely: feldspathic-ceramic (Vita Mark II-VM2), lithium-disilicate glass-ceramic (IPS e.max CAD-E.

Comparing Fracture Resistance and the Time Required for Two Different Fiber Post Removal Systems.

Purpose: To compare two fiber post removal techniques in terms of fracture resistance and time required for post removal.

Materials And Methods: Post space was prepared to a 9-mm depth in each root canal. The roots were randomly divided into three groups of 15 specimens each.

Comparative radiopacity of conventional and full-contour Y-TZP ceramics.

The purpose of this study was to evaluate the radiopacity of different yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramics used in the fabrication of fixed dental prostheses. Disk-shaped specimens (N=120, n=30 per group) were fabricated with thicknesses of 0.3, 0.

Radiopacity measurements of direct and indirect resin composites at different thicknesses using digital image analysis.

Radiopacity is an important property of composite materials for clinical diagnosis. For seven direct composites (Aelite LS Posterior, Aelite All-Purpose Body, Quadrant Universal LC, Clearfil Majesty Posterior, Clearfil Majesty Esthetic, Filtek Ultimate Dentin, IPS Empress Direct Dentin) and six indirect composites (Ceromega, Epricord, Estenia C&B, Tescera, Signum Ceramis, Solidex), diskshaped specimens (N=260, n=10 per group) were fabricated for two thicknesses at 1 and 2 mm. Average radiographic density of each composite material was calculated.

Fracture resistance of endodontically treated teeth restored with ceramic inlays and different base materials.

This study evaluated the fracture resistance of endodontically treated teeth restored with different base materials and mesioocclusal-distal (MOD) ceramic inlays. Fifty mandibular molars were assigned into five groups (n=10 per group). Group1 (control) comprised intact molar teeth without any treatment.
