BACKGROUND The condition of the denture bearing tissues may be adversely affected by high stress concentration during function. Chairside Denture (Hard and Soft) reliners are used to distribute forces applied to soft tissues during function. Tensile and shear bond strength has been shown to be dependent on their chemical composition. A weak bond could harbor bacteria, promote staining and delam...

background: the clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (rmgic) bonding to both dentin and resin composite. therefore, the shear bond strength (sbs) of resin composite bonded to rmgic utilizing different resin adhesives versus a gic-based adhesive was compared. materials and methods: in this in vitro study, 84 holes (5×2 mm) were pre...

In the present study, the growth of a single isolate of Candida albicans on seven saliva-, serum-coated or protein free (uncoated), thermocycled (4-70 degrees C for 1 min, respectively; 0, 1000 and 10 000 times) commercial resilient lining materials was investigated by monitoring pH changes in growth media. The inhibitory effect of the tissue conditioners on fungal growth was observed using thr...

The aim of this study was to evaluate the flexural strength of acrylic resin bars by varying the types of resin polymerization and reinforcement methods. Fourteen groups (N=10) were created by the interaction of factors in study: type of resin (self-cured (SC) or heat-cured (HC)) and reinforcement method (industrialized glass fiber (Ind), unidirectional glass fiber (Uni), short glass fiber (Sho...

BACKGROUND The utilization of computer-assisted designing and computer-assisted milling CAD\CAM resins in the fabrication of removable prostheses is a modern-day concept that offers many advantages over the use of the traditional polymethylmethacrylate (PMMA). AIM This study instigated some of the mechanical properties of CAD\CAM denture base resin including the amount of residual monomer. ...

Heat-cured acrylic resin is the most commonly used denture base material due to its biological, mechanical, chemical, and physical properties. Denture cleaning, which essential for successful use, can be facilitated by utilizing cinnamon extract Cinnamomum burmannii 20% chlorhexidine 0.2% as effective cleaning agents. However, these materials affect properties of denture, such a dimensional cha...

This study verified the optical density of four composite resin luting agents - RelyX ARC (RY), Enforce (E), C&B Cement (CB) and Flow it (FI), at thicknesses of 2, 3, and 4 mm. The optical density of the luting agents was compared with that of enamel and dentin at the same thicknesses. Fifteen tooth crowns were embedded in PVC cylinders with self-cured acrylic resin. In addition, acrylic resin ...
