OBJECTIVE The purpose of this study was to investigate the polymerization temperature of a bulk filled composite resin light-activated with various light curing modes using infrared thermography according to the curing depth and approximation to the cavity wall. MATERIAL AND METHODS Composite resin (AeliteFlo, Bisco, Schaumburg, IL, USA) was inserted into a Class II cavity prepared in the Tef...

To overcome the disadvantages of computer-aided design/computer-aided manufacturing (CAD/CAM) processed indirect restorations using glass-ceramics and other ceramics, resin nano ceramic, which has high strength and wear resistance with improved polish retention and optical properties, was introduced. The purpose of this study was to evaluate the shear bond strength and fracture pattern of indir...

If sweet potatoes are to be stored for any leilgth of time they must be subjected immediately after digging to a suitable combination of temperature and humidity for effective curing of the roots. The physiology of curing is imperfectly understood because of our limited information of the essential chemical changes in the roots during curing,. Previous studies have been confined chiefly to carb...

one of the common methods to cure unsaturated polyester resins is to use dual initiators. in order to produce an appropriate composite, it is necessary to know the effect of dual initiators on curing behavior. in this paper the effect of benzoyl peroxide, bpo, and tertiary butyl perbenzoate, tbpb, and their mixtures on thermal curing of an unsaturated polyester resin have been investigated. bpo...

There is difficult to imagine modern production of electrical devices without components containing organic substances. This fact is mainly concerned to composite materials, in which the bond component is made of organic substance. The intricate curing reactions have been proceeding during the composites technological curing as well as during the device operation, where mostly the thermal-oxida...

Plasmids are extrachromosomal pieces of double-stranded circular DNA which have the capability to replicate independently of the.Growth dynamics of multiple component communities of bacteria. Thus curing by acridines normally involves loss of the whole plasmid.Plasmids are extrachromasomally replicating molecules of DNA present in bacteria.Plasmid curing is a process of completely removing plas...

This paper addresses the viscoelastic behaviour of a commercially available cold-curing structural epoxy adhesive, under different preparation, curing and hygrothermal conditions. The main parameters studied were preparation method (influence degassing temperature initial curing), creep stress level, Tensile tests last up to 2400 h. Test results revealed that has great influence on tensile prop...

Background: Effective polymerization of the composite resin is essential to obtain long term clinical success and has a great importance obtaining improved mechanical properties. The purpose of this study was to measure the effect of the light intensity of LED and QTH curing devices in relation to the light distances, on the hardness (KHN) of two light cure nano-resin composite. Material and Me...
