“…It was observed that modulus obtained using nanoindentation agreed very well with results obtained by traditional wileyonlinelibrary.com 381 methods (p < 0.05), such as the three-point bending test.

“…[ 60 ] For all composites examined (containing different amounts of fi ller type and concentration), elastic deformation was observed at low scratch loads whereby the composite was able to fully recover after removal of the normal load. A larger scratch load resulted in elastic and plastic deformation with the plastic deformation manifested as ductile grooving that transitioned into ploughing with increasing applied normal force.…”

Combinatorial and high-throughput methods have been increasingly used to accelerate research and development of new biomaterials. These methods involve creating miniaturized libraries that contain many specimens in one sample in the form of gradients or arrays, followed by automated data collection and analysis. This article reviews recent advances in utilizing combinatorial and high-throughput methods to better understand cell-material interactions, particularly highlighting our efforts at the NIST Polymers Division. Specifically, fabrication techniques to generate controlled surfaces (2D) and 3D cell environments (tissue engineering scaffolds) as well as methods to characterize and analyze material properties and cell-material interactions are described. In conclusion, additional opportunities for combinatorial methods for biomaterials research are noted, including streamlined sample fabrication and characterization, appropriate and automated bioassays, and data analysis.

“…A high recovery is indicative of elastic strain, whereas a lower recovery suggests significant plastic (permanent) deformation. 17 In Figure 6, all samples showed elastic recovery values greater than 60% for the four analyzed loads. These values are in the same range found for many different polymers submitted to scratch tests with different loads and geometry tips.…”

Objective: To evaluate the material composition, mechanical properties (hardness and elastic modulus), and scratch resistance of the coating of four commercialized esthetic orthodontic archwires. Materials and Methods: The coating composition of esthetic archwires was assessed by Fouriertransform infrared spectroscopy (FTIR). Coating hardness and elastic modulus were analyzed with instrumented nano-indentation tests. Scratch resistance of coatings was evaluated by scratch test. Coating micromorphologic characteristics after scratch tests were observed in a scanning electron microscope. Statistical differences were investigated using analysis of variance and Tukey post hoc test. Results: The FTIR results indicate that all analyzed coatings were markedly characterized by the benzene peak at about 1500 cm 21. The coating hardness and elastic modulus average values ranged from 0.17 to 0.23 GPa and from 5.0 to 7.6 GPa, respectively. Scratch test showed a high coating elasticity after load removal with elastic recoveries .60%, but different failure features could be observed along the scratches. Conclusion: The coatings of esthetic archwires evaluated are probably a composite of polyester and polytetrafluoroethylene. Delamination, crack propagation, and debris generation could be observed along the coating scratches and could influence its durability in the oral environment. (Angle Orthod. 2015;85:777-783.)

“…The lowest DC of AL on the bottom surface, despite the highest filler content, may be related to the greatest attenuation of the incident light in AL. Generally other factors such as photoinitiator concentration, monomers commixture ratio, and degree of crosslink can also be involved to the resultant DC in addition to the light attenuation [19][20][21] . In the oral cavity, the restored composite resins always interact with water.…”

The purpose of this study was to evaluate how the temperature affects the stability of polymerized additional photoinitiator-containing composite resins. Five resin products were light-cured using a quartz-tungsten-halogen, and single and dual emission peaks lightemitting diodes. The degree of conversion (DC) and water sorption, solubility, and color change of the specimens were evaluated after immersion in the solutions of different temperatures (4, 37, and 60ºC) for 14 days. On the top surface, the light-curing units had no significant influence on DC of the tested specimens. On the bottom surface, the influence was inconsistent. As the solution temperature increased, water sorption also consistently increased in all specimens, whereas solubility changed inconsistently. Water sorption and solubility had a high linear correlation only at low temperature solution. Color change of the specimens was similar, mostly slight, and statistically inconsistent regardless of solution temperature. The restored composite resins are needed to avoid contact with hot solutions for durable dental restoration.
