In vitro toothbrushing abrasion of dental resin composites: packable, microhybrid, nanohybrid and microfilled materials.
This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens (n = 20) were prepared. Half of the samples were submitted to 60,000 strokes, at 4 Hz, with a de...

15 صفحه اولResistance of nanofill and nanohybrid resin composites to toothbrush abrasion with calcium carbonate slurry.
The aim of this study was to investigate the wear of four nanofilled resin composites using simulated toothbrushing for 50,000 cycles with calcium carbonate slurry. The depth of abrasion and roughness (Ra) were measured after each 10,000 brushing cycle. The surface texture of the worn samples was examined by SEM.The wear depths of the nanofill Filtek Supreme XT (FIL), the nanohybrides Grandio (...
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...
متن کاملThe effect of re-bonding using surface sealant or adhesive system on microleakage of class V resin composite restorations
BACKGROUND Microleakage is still one of the defects of resin composites that can lead to treatment failure; and re-bonding technique is one of the effective ways to reduce it. This study evaluated the effect of re-bonding with a surface sealant or a dentin adhesive on microleakage in class V microhybrid, nanohybrid, and packable composite restorations. MATERIALS AND METHODS In this in vitro s...
