Evaluation Of Colour Reproduction Of Cad/Cam Lithuim-Disilicate Veneers Of Different Thicknesses And Translucency, Sahar H. Fikry, Tarek Salah Morsi, Mennatallah M. Wahba, Amr El-Etreby

Future Dental Journal

Background: With the increasing patients’ demand for a perfect smile, the call for highly aesthetic and yet minimally invasive veneers has surmounted. Objective: The aim of this study was to evaluate the colour of CAD/CAM lithium disilicate veneers fabricated in different thicknesses and different translucencies of the lithium disilicate blocks. Materials and Methods: Forty discs of lithium disilicate glass-ceramic (IPS e.max CAD) of shade A1 of both high and low translucency (HT, LT) were tested for their colour reproduction. HT and low LT blocks were cut in the form of plates of dimensions (12 x 14 mm) and of different …

Effect Of Thickness On Translucency And Masking Ability Of A Recently Developed Single-Shade Resin Composite With Enhanced Opacity: An In Vitro Comparative Study, Sayed Mohamed Ghorab, Hagag Abd Elkader Atya

Future Dental Journal

ABSTRACT

Objective: This study aimed to evaluate the effects of thickness changes on translucency and masking ability of a recently developed single shade resin composite material with enhanced opacity comparing it with a traditional opaque-shade one.

Material and methods: Two brands of composite resins; Omnichroma blocker (OCB) and G-aenial Anterior (GA) in opaque A2 (OA2) shade were selected to enroll the study. Color coordinates of each composite were determined at 0.5, 1, and 1.5 mm thicknesses (n=10/thickness) on four different backgrounds (white baking, black baking, C4 shade porcelain baking and the backing of material itself) by using a …
