Omnichroma is a smart monochromatic material and believed to attain the shade of surrounding tooth structure in which it placed. However, color stability this unknown. Therefore, study was conducted evaluate effect different pH beverages on composite its comparison with micro-hybrid resin. Sixty extracted human maxillary premolars shades, viz. A2, A3, B2 B3, were selected equal numbers. A Class...

Amaç: Bu çalışmanın amacı, Cention N isimli dolgu maddesinin radyoopasitesinin farklı restoratif materyaller ile karşılaştırılmalı olarak değerlendirilmesidir. Gereç ve yöntem: Çalışmada, 9 materyal, 1 mm kalınlıkta mine dentin içeren süt dişi kesiti kullanıldı. Geleneksel cam iyonomer (Kavitan Plus, Spofa Dental, Czech Republic), rezin modifiye (Riva Light Cure, SDI, LC/Southern Dental Industr...

The long-term success of a composite restoration largely depends on its smoothness, which can be achieved by the appropriate polishing tools and material selection. purpose this study was to evaluate surface roughness two materials after application selected systems. Filtek Ultimate (FU) Z250 (FZ) were tested. Forty specimens each prepared. After polymerization under Mylar strip, five samples f...

objectives: repairing composite restorations is a challenging procedure especially when two different types of composites are used. this study aimed to compare the repair strength of silorane-based composite (sc) (filtek p90) with that of preheated sc, methacrylate composite (mc)(z250), flowable mc (filtek supreme plus) and different adhesive/composite combinations. materials and methods : eigh...

The mechanical properties of the light-cured composite resins are related to the material composition, but also vary according to the light-source characteristics used for polymerization. In this study we followed the compressive strength variation for a light-cured composite resin according to the time of exposure to the curing light. With that end in view,18 test pieces were made from a light...

The purpose of this study was to evaluate the discoloration of two nanohybrids, two microhybrids, and a posterior composite resin restorative material upon exposure to different drinks--namely tea, cola, coffee, red wine, and water. The colors of all specimens before and after storage in the solutions were measured by a colorimeter based on CIE Lab system, and the color differences thereby calc...

AIM The aim of this study was to investigate the effect of different incremental insertion techniques, photoactivation, and restorative phases on thermal variations occurring during the polymerization of Filtek Z250 composite resin. METHODS AND MATERIALS The experiment was conducted using 90 bovine incisor teeth. The teeth were randomly assigned to three groups according to the technique used...
