The aim of this study was to assess the uniaxial tensile strength after thermal cycling in replicas of CeraOne abutments (abutment and coping sets), using four types of cements (n = 10). A zinc phosphate cement (Fosfato de Zinco/ SSW), a resin-modified glass ionomer cement (RelyX luting / 3M-ESPE), a zinc oxide-eugenol cement (ZOE/ SSW) and a zinc oxide cement without eugenol (TempBond NE/ KERR...

A survey was conducted to ascertain the variations practiced in powder/liquid (P/L) ratio of Glass Ionomer Cement (GIC) used as restorative and luting material in dental clinics of Karachi. It has been observed that in the use of GIC brands, 33% (Fuji 2) and 36% (Gold Label 2) of the dentists, did not follow the recommended P/L ratios for restorative purposes. Similarly, 67% (Fuji 1) and 29% (G...

PURPOSE Manufacturers commonly provide information on the physical properties of dental materials, but information on their antibacterial properties is often missing. This study determined the antibacterial properties of four currently used orthodontic band cements against three different strains of Streptococcus mutans. METHODS The cements utilized were Durelon, Ketac, Mizzy Zinc Phosphate, ...

Orthodontic bands are retained on the crowns o f teeth by the luting action o f the cement. Studies by several work­ ers have demonstrated the inability o f zinc phosphate cements to produce an effective marginal seal and have shown microleakage to occur along the walls o f cavities restored with zinc phosphate cements. Differences in the coefficients o f thermal expansion between enamel, denta...

Resin-based cements have been frequently employed in clinical practice to lute indirect restorations. However, there are numerous factors that may compromise the clinical performance of those cements. The aim of this literature review is to present and discuss some of the clinical factors that may affect the performance of current resin-based luting systems. Resin cements may have three differe...

PURPOSE To evaluate the fixation strength at the interface between the Kerboull-type plate and bone cement in 6 experimental conditions. METHODS Experimental materials comprised a simulated acetabular block, a simulated Kerboulltype plate, a pressuriser cover, a pressuriser arm, and bone cement. The simulated Kerboull-type plate was placed on the simulated acetabular block, with the pressuris...

BACKGROUND Glass polyalkenoate cements (glass ionomer cements) are widely used in restorative dentistry and now a day the material of choice for bone cements. The aim of the study is to examine the variations produced by exposure to acid for dental Glass Ionomer Cement (GIC) glass particles of different composition. It also involves the study of the effect of replacing Ca by Sr in glass ionomer...

In the early 1980s, scientists at the American Dental Association Le Geros et al. [1] and Brown & Chow [2-5] first explored the possibility of generating a monolithic calcium orthophosphate ceramic at ambient or body temperature via a cementation reaction among one or more component of calcium orthophosphate precursors. Presently this type of materials is referred to as calcium phosphate cement...
