“…RelyX Veneer, VariolinkII, and Nexus 2 all contained bisphenol A-glycidyl methacrylate (Bis-GMA), which has two hydroxyl groups per molecule that can hydrogen-bond with absorbed water 36) . In addition, the nature and quality of links between the fillers and matrix resins are also important 4,37) with regard to water sorption. It is difficult to correlate data for sorption and solubility from other studies, as the results will inevitably differ due to the employment of different time periods and different units of measurement 38) .…”

“…It should be reiterated that clinically, solubility and sorption may cause stressinduced degradation of the luting cement 1) . The latter then leads to debonding and/or fracture of the restoration 4,5) , increased marginal leakage 6,7) , and increased potential for secondary caries 2) . Resin-based luting cements are becoming increasingly used in clinical practice for porcelain veneers, all-ceramic crowns, and more recently, inlay, onlay, and laminate restorations.…”

This study examined the solubility, sorption, and dimensional change of eight luting cements in two different solutions: 50% ethanol:water and distilled water. Ten disk specimens were prepared of each material following the manufacturers ' instructions, and then ground with silicone carbide paper. Sorption and solubility were calculated by weighing the specimens before and after immersion and desiccation. Data were analyzed by two-way ANOVA, Tukey ' s HSD and Fisher ' s PLSD tests. GC Fuji Plus and RelyX Luting2 showed the highest values of sorption and solubility both in water and ethanol:water. The percentage changes in volume for Maxcem, Nexus 2, Panavia F, RelyX Veneer, and VariolinkII were considerably smaller than for GC Fuji Plus, RelyX Luting2, and seT in both water and ethanol:water and after desiccation. Stability occurred within 2 weeks for all the eight materials when in water, while GC Fuji Plus, Maxcem, Panavia F and seT took 3 to 4 weeks to stabilize in ethanol:water.

“…The resin matrix of the composites was believed to have absorbed water -usually in a small percentage, and which then changed the magnitude of some physical properties 41) . Differences in water sorption values also stemmed from differences in the following aspects: chemical composition of the matrix monomers, diffusion coefficient and boundary conditions at the surface of material, pore size and pore volume, and the rate of polymerization 13,[42][43][44] . Metafil Flo exhibited the lowest water sorption rate among the FCRs, but that of Metafil C was in the mid range of CCRs.…”

Flexural Performance of Flowable versus Conventional Light-cured Composite Resins in a Long-term in vitro Study

et al. 2008

The purpose of this study was to evaluate the flexural strength, flexural modulus, modulus of resilience, and water sorption of four flowable light-cured composite resins (FCRs). Results were then compared with four conventional composite resins (CCRs) and a minifilled hybrid light-cured composite resin, which served as a control. Twenty specimens were flexural tested immediately after curing, while others were stored in water at 37℃ for 1 month, 3 months, 6 months, or 1 year before flexural testing. The 1-year specimens were weight-measured at designated time intervals to examine water sorption. All FCRs, except Point 4 Flowable, showed higher flexural strength values than their CCR counterparts (p<0.05, Scheffé' s test). After one-year water storage, the flexural strengths and flexural moduli of FCRs increased 1.5-fold or more when compared with the immediate condition. In most cases, the moduli of resilience of FCRs were higher than those of CCRs. In conclusion, it was found that FCR and CCR with the same brand name had very different characteristics and mechanical properties.

“…[57][58][59][60] Osmosis droplets are observed at the transition between the adhesive layer of 1-stepSE and 2-stepER adhesives and the composite resin material. [57][58][59][60] This transition contains uncured monomers from the oxygen-inhibition layer, 48,57,58 which would have resulted in decreased DC in our study. The hydrophobic resin coat would have copolymerized with the uncured surface of the adhesive layer from the 1-step adhesive, resulting in higher DC due to the consumption of residual double bonds.…”

Dental education in the United States has gone through several major changes from the beginnings of dentistry as a trade or vocation learned through apprenticeships or on-the-job training or practiced by self-taught barber surgeons to the current system of dental school training. The evolution to the pinnacle of excellence in restorative and preventive arts did not happen overnight or by accident. Dr Horace H. Hayden and Dr Chapin A. Harris, two dental practitioners in Baltimore, Maryland, were instrumental in founding the first dental sc...
