OBJECTIVE Since bulk-fill (BF) resin composites should cure efficiently to a depth up to 4mm, the aim of the study was to determine the time-dependence of degree of conversion (DC) at that depth during 24h post-irradiation. METHODS Eight representative BF resin composites were studied [x-tra base (XTB), Venus Bulk Fill (VBF), Tetric EvoCeram Bulk Fill(More)
STATEMENT OF THE PROBLEM Drug addiction or substance abuse is an endemic habit globally. At present there is no data available regarding the temporomandibular joint status, occlusal and cervical tooth wear and facial pain among substance abusers from the Saudi Arabia. PURPOSE The aim of the study was to investigate the temporomandibular joint status,(More)
OBJECTIVE To study the effect of compositional variables and temperature (25°C and 37°C) on the rheological properties of contemporary resin composites. METHODS Fourteen commercial resin composites with different resin matrices of Bis-GMA and TEGDMA, different filler loading (41-65, v/v) and particle sizes (ranging 5nm to 20μm) were studied using a(More)
OBJECTIVES To study the effect of resin matrix and maturation time (1 and 24 h) on the creep deformation of resin-composites, two of which have matrix-forming monomers that are either bis-GMA free or have an ormocer structure between the CC groups. METHODS Five resin-composites: four commercial and one experimental were investigated. Six specimens were(More)
