15 صفحه اولMicrohardness evaluation of resin composites polymerized by three different light sources.
This study examined the surface microhardness of four kinds of resin composites with different fillers and resin matrices. Ten specimens of 2 mm thickness and 4 mm diameter of each resin composite were polymerized using a halogen light, a blue light-emitted diode, and a plasma arc unit. Microhardness evaluation was performed at top and bottom surfaces for each specimen using a Vickers microhard...
متن کاملEffect of reduced exposure times on the microhardness of 10 resin composites cured by high-power LED and QTH curing lights.
PURPOSE To compare the effect of reduced exposure times on the microhardness of resin composites cured with a "second-generation" light-emitting diode (LED) curing light and a quartz-tungsten-halogen (QTH) curing light. METHODS Ten composites were cured with a LED curing light for 50% of the manufacturers" recommended exposure time or a QTH light at the high power setting for 50% of the recom...
متن کاملPackable Resin Composites Lieutenant Joseph C . Joyce
Introduction Increased demand by patients and clinicians for esthetic restorations coupled with the public’s concern about mercury have resulted in an escalating use of resin composite materials (1). Resin composite is now often utilized to restore tooth surfaces previously accomplished with silver amalgam. Packable (a.k.a. moldable or condensable) resin composites are the product of vast amoun...
