BACKGROUND Given the high prevalence of oral candidiasis and the restricted number of antifungal agents available to control infection, this study investigated the in vitro antifungal activity of alcohol vinegar on Candida spp. and its effect on the physical properties of acrylic resins. METHODS Tests to determine the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration...

The reparability of dual-cured resin composite core buildup materials using a light-cured one following one week or three months storage, prior to repair was evaluated. Two different dual-cured resin composites; Cosmecore™ DC automix and Clearfil™ DC automix core buildup materials and a light-cured nanofilled resin composite; Filtek™ Z350 XT were used. Substrate specimens were prepared (n = 12/...

Abstract In 3D printing technology, unwanted resin properties such as low mechanical, thermal, electrical, and biocompatibility can be enhanced by using proper fillers. this study, sucrose urethane microparticles, acrylic modified are used to improve the of final object without losing other resolution. Modification is confirmed FTIR spectroscopy hydrogen bonding index enhancement after modifica...

Acid etching and filled acrylic materials have been generating great interest in the past few years because of increased public demand for esthetic restorations and alternatives to amalgam. Composite resin and ceramic inlays, which use adhesive bonding, were introduced to make possible toothcolored restorations. The physical properties of composite resin restorations, and their poor wear resist...

The aim of this study was to evaluate in vitro the marginal microleakage of different materials used as pit-and-fissure sealants (Delton, Filtek Flow, Dyract Flow and Vitremer). Fifty-six extracted sound human third molars were randomly assigned to 4 groups (n=14). After sealant placement, the teeth were thermocycled (500 cycles; 5 degrees C, 37 degrees C and 55 degrees C), isolated, immersed i...

Purpose: To evaluate the effect of incorporation 0.1%, 0.3%, and 0.5% concentrations titanium oxide, aluminum silica nanoparticles in heat-cured acrylic resin denture base on peel bond strength to a silicone liner. Methods: A total number 100 samples were prepared classified into control group three groups according type nanoparticle. Each was subgroups concentration nanoparticle (n=10). Silico...

The purpose of this in vitro study was to investigate the effect of 1% NaOCl (15 min) and MTAD on dentine shear bond strength, when using the Scotchbond XT(3M ESPE) adhesive system. Thirty extracted, human, third molar teeth were embedded into metal rings with self-curing acrylic resin. The teeth were ground wet using 600-grit silicone-carbide paper to expose superficial dentine. The samples we...

Systematic evaluations of the properties of prosthetic facial materials began to appear in 1969 with a report by Cantor et a/. ’ They reported that plasticized poly(methyl methacrylate) was the best material with respect to resistance to tearing and degree of elongation. A year later, Walter2 reported the specific gravity, water sorption, thermal conductivity, strain in compression, and permane...

STATEMENT OF PROBLEM One of the most clinical challenging issues in prosthodontics is debonding of soft liners from the denture base. PURPOSE The aim of this study was to evaluate and compare tensile bond strength between soft liner and heat-cured acrylic resin when immersed in two different types of denture cleanser and distilled water, at different period of times. MATERIALS AND METHOD In...
