Objectives: Metal-ceramic restorations are the standard by which all esthetic restorations are measured. Fracture of dental restorations is a multifactorial problem, which is serious and costly. Debonding of porcelain from metal substructure and the bond strength depend on many factors. The purpose of this study was to determine whether or not the opaque porcelain thickness has a significant ef...
Background & Aims of the Study: Methicillin-resistant staphylococcus aureus (MRSA) is considered as a major pathogen in public health concern.

Objective: In this study, the effects of ceramic, chromium-nickel (Cr-Ni) and ceramic opaque sinterized on chromium-nickel (Cr-Ni+opaque) post-core materials and different colored (opaque white, white, yellow and brown) cements on final color of all-ceramics materials (In-Ceram, IPS Empress and IPS Empress II) were investigated. Material and Methods: Three groups of post-cores (ceramic, Cr-Ni a...
NGC 6397 is the second closest globular star cluster to the Sun. Using 5 days of time on the Hubble Space Telescope, we have constructed an ultradeep color-magnitude diagram for this cluster. We see a clear truncation in each of its two major stellar sequences. Faint red main-sequence stars run out well above our observational limit and near to the theoretical prediction for the lowest mass sta...
