AIM To measure the light transmission through different esthetic posts and to evaluate the degree of polymerization of dual cure resin cement cured through these posts. MATERIALS AND METHODS The posts were divided into two experimental groups i.e. Group A (D.T. Light post); Group B (D.T. White post) and control i.e. Group C (metal post), each group having 10 samples. Posts of each group were ...

results two major themes were extracted from the analysis of the transcripts: “comprehensive caring commitment” and “patients’ medication grudge”. conclusions according to the findings, the nurses are in a unique position to care for people with ms; therefore they should be ready to provide high-quality patient care in ms patients. patients must be encouraged to study about their condition and ...

Aims: This study was performed to compare microleakage in class II composite restorations with flowable composites and dual cure composite resin as intermediate material and also to evaluate the effect of delayed light polymerization of dual cure composite base on microleakage. Materials and methods: Class II box cavities were made with air water spray and divided into four groups. Group 1 was ...

Aim The aim of this study is to compare and to evaluate effect of curing light and curing modes on the nanohybrid composite resins with conventional Bis-GMA and novel tricyclodecane (TCD) monomers. Methodology Two nanohybrid composites, IPS empress direct and charisma diamond were used in this study. Light-emitting diode (LED)-curing unit and quartz-tungsten-halogen (QTH)-curing unit which we...

Micron-sized white light propagation invariant beams generated by a simple and compact fiber device are presented. The all-fiber device is fabricated by splicing a short piece of large-core multimode fiber onto a small-core single mode white light delivery fiber. Because this fiber device offers an inherent spatial coherence, nondiffracting white light beams can be created with a temporally inc...

OBJECTIVE To compare the polymerization effectiveness of two resin composites cured with a quartz tungsten halogen (QTH) lamp or a light emitting diodes (LED) unit. STUDY DESIGN Filtek Z250 (3M ESPE) and Spectrum TPH (Dentsply DeTrey) resin composites were placed in 9 mm deep and 4 mm wide metallic molds and cured using the QTH light Hilux 200 (Benlioglu) or the LED unit Smartlite IQ (Dentspl...

PURPOSE The aim of this study was to evaluate the effect of thickness of zirconia on curing efficiency of resin cements. MATERIALS AND METHODS Four discs with 4.0 mm in diameter were prepared from non-HIP translucent zirconia blocks using a CAD/CAM system and feldspathic ceramic was layered onto discs. Thus, 4 ceramic disc samples were fabricated: (G) 0.5 mm zirconia- as a control group, (G1)...

In a small tokamak, the visible light emission is observed and used to investigate plasmas' behavior with fast camera. However, reflected causes systemic error in measuring emitted from plasma. this paper, we managed overcome reflection effect ray-tracing technique which utilized synthetic diagnostic platform of tokamak device PHiX at Tokyo Institute Technology using Raysect CHERAB python libra...

The aim of this study was to evaluate the Knoop hardness after 15 min and 24 h of different shades of a dual-cured resin-based cement after indirect photoactivation (ceramic restoration) with 2 light-curing units (LCUs). The resin cement Variolink II (Ivoclar Vivadent) shade XL, A2, A3 and opaque were mixed with the catalyst paste and inserted into a black Teflon mold (5 mm diameter x 1 mm high...
