Evaluation of depth of cure and Knoop hardness in a dental composite photo-activated using different methods. (1/142)

The aim of this study was to evaluate the depth of cure and Knoop hardness in the P60 composite resin photo-activated using different methods. A bipartite brass matrix (3 mm in diameter X 11 mm in height) was filled with the composite and photo-activation was performed using continuous light, exponential light, intermittent light, plasma arc curing (PAC) or light-emitting diodes (LED). After opening the matrix, the uncured material was removed with a steel spatula and the polymerized composite was measured using a pachymeter. The specimens were then included in self-curing acrylic resin and worn longitudinally and the hardness was measured on the surface and at depths of 1, 2, 3, 4 and 5 mm. The data were analyzed by ANOVA and Tukey's test (5%). The results showed that the depth of cure was higher with the intermittent light, followed by continuous light, exponential light, PAC and LED methods. Up to a depth of 2 mm, all methods revealed similar hardness values, but there were differences between them at other depths, at which LED demonstrated the lowest values followed by PAC.  (+info)

Effect of the increase of energy density on Knoop hardness of dental composites light-cured by conventional QTH, LED and xenon plasma arc. (2/142)

The aim of this study was to evaluate the effect of the increase of energy density on Knoop hardness of Z250 and Esthet-X composite resins. Cylindrical cavities (3 mm in diameter X 3 mm in depth) were prepared on the buccal surface of 144 bovine incisors. The composite resins were bulk-inserted and polymerized using different light-curing units and times: conventional QTH (quartz-tungsten-halogen; 700 mW/cm(2); 20 s, 30 s and 40 s); LED (light-emitting diode; 440 mW/cm(2); 20 s, 30 s and 40 s); PAC (xenon plasma arc; 1700 mW/cm(2); 3 s, 4.5 s and 6 s). The specimens were stored at 37 degrees C for 24 h prior to sectioning for Knoop hardness assessment. Three measurements were obtained for each depth: top surface, 1 mm and 2 mm. Data were analyzed statistically by ANOVA and Tukey's test (p<0.05). Regardless of the light source or energy density, Knoop hardness of Z250 was statistically significant higher than that of Esthet-X (p<0.05). Specimens cured with PAC had lower hardness than those cured with QTH and LED (p<0.05). Higher Knoop hardness was obtained when the energy density was increased for LED and PAC (p<0.05). No statistically significant differences (p>0.05) were found for QTH. Knoop hardness values decreased with the increase of depth. The increase of energy density produced composites with higher Knoop hardness means using LED and PAC.  (+info)

Color stability of composites subjected to accelerated aging after curing using either a halogen or a light emitting diode source. (3/142)

The purpose of this study was to evaluate, in vitro, the color stability of three composite resins of two different shades (A3 and C3) cured with either a quartz tungsten halogen (QTH) or a light emitting diode (LED) source. Forty specimens (20 x 2 mm) were prepared for each composite (Tetric Ceram, Heliomolar and Esthet-X), being 20 for each shade. In each group, 10 specimens were light-cured using the QTH unit and 10 with the LED source. The shade of the materials was evaluated before and after submitting the specimens to artificial accelerated aging (4 h UV-B/4 h condensing vapor), using a reflection spectrophotometer. deltaE means were calculated and analyzed statistically by 2-way ANOVA and Tukey's test at 5% significance level. Both A3 and C3 shades of Esthet-X composite resin showed the lowest color change when cured with the QTH light, while Tetric C3 cured with the QTH light showed the highest color change.  (+info)

Influence of shade and irradiation time on the hardness of composite resins. (4/142)

This study tested the following hypotheses: 1. increasing light irradiation time (IT) produces greater values of superficial hardness on different depths (0 and 3 mm); and 2. a dark shade composite (A3) needs longer IT than a light shade composite (A1) to produce similar hardness. Disk-shaped specimens (n=24 per shade) were fabricated using a 3-mm-thick increment of composite resin (Z100). Specimens were randomly assigned to 3 groups (n=8) according to the IT (400 mW/cm2) at the upper (U) surface: A1-10 and A3-10: 10 s; A1-20 and A3-20: 20 s; A1-40 and A3-40: 40 s. Specimens were stored in black lightproof containers at 37 masculineC for 24 h before indentation in a hardness tester. Three Vickers indentations were performed on the U and lower (L) surfaces of each specimen. The indent diagonals were measured and the hardness value calculated. The results were analyzed statistically by ANOVA and Tukey's test (alpha=0.05). Statistically significant differences were found between U and L surfaces of each composite shade-IT combination (p=0.0001) and among the ITs of same shade-surface combination (p=0.0001), except between groups A1-20U and A1-40U, confirming the study hypothesis 1 and partially rejecting the hypothesis 2.  (+info)

Effect of veneering materials and curing methods on resin cement knoop hardness. (5/142)

This study evaluated the Knoop hardness of Enforce resin cement activated by the either chemical/physical or physical mode, and light cured directly and through ceramic (HeraCeram) or composite resin (Artglass). Light curing were performed with either conventional halogen light (QTH; XL2500) for 40 s or xenon plasma arc (PAC; Apollo 95E) for 3 s. Bovine incisors had their buccal surfaces flattened and hybridized. On these surfaces a mold was seated and filled with cement. A 1.5-mm-thick disc of the veneering material was seated over this set for light curing. After storage (24 h/37 masculineC), specimens (n=10) were sectioned for hardness (KHN) measurements in a micro-hardness tester (50 gf load/ 15 s). Data were submitted to ANOVA and Tukey's test (alpha=0.05). It was observed that the dual cure mode yielded higher hardness compared to the physical mode alone, except for direct light curing with the QTH unit and through Artglass. Higher hardness was observed with QTH compared to PAC, except for Artglass/dual groups, in which similar hardness means were obtained. Low KHN means were obtained with PAC for both Artglass and HeraCeram. It may be concluded that the hardness of resin cements may be influenced by the presence of an indirect restorative material and the type of light-curing unit.  (+info)

Effect of light-curing methods on resin cement Knoop hardness at different depths. (6/142)

This study evaluated, using Knoop hardness test, the polymerization depth of Rely-X dual-cured resin cement activated by chemical reaction alone (control group) or by chemical/physical mode with light curing through a 1.5-mm-thick ceramic layer (HeraCeram). Bovine incisors had their buccal surface flattened and hybridized. On this surface, a rubber mould (5 mm diameter; 1 mm high) was bulk filled with cement. Either a polyester strip or a 1.5-mm-thick disc of the veneering material was seated over this set. Light curing was performed with either conventional halogen light (QTH; XL2500) for 40 s, light-emitting diode (LED; Ultrablue Is) for 40 s or xenon plasma arc (PAC; Apollo 95E) for 3 s. In a control group, cement setting occurred by chemical reaction alone. After storage dry in dark (24 h/37 degrees C), the specimens (n=5) were sectioned for hardness (KHN) measurements at three depths in a microhardness tester (50 gf load/15 s). Data were submitted to ANOVA and Tukey's test (alpha = 0.05). Rely-X cement presented higher Knoop hardness values when the QTH and LED LCUs were used, compared to the control group and PAC. Light curing with PAC resulted in lower hardness compared to the control group. Cement hardness was significantly lower in deeper regions.  (+info)

The effects of light intensity and light-curing time on the degree of polymerization of dental composite resins. (8/142)

The aim of this study was to investigate the effects of light intensity and light-curing time on the polymerization of composite resins. Four composite resins were light-cured with different light-curing conditions. In the non-thermocycled case, specimens showed almost the same or similar microhardness values if energy density was identical or similar. As the energy density decreased, maximum polymerization shrinkage decreased. At higher energy densities, specimens had a lower coefficient of thermal expansion than at lower energy densities. At the same or similar energy density, most resin products showed coefficient values which were not statistically different. After 10,000 thermocycles, specimens showed decreases of 2.4-16.5% and 4.6-25.2% in microhardness and coefficient of thermal expansion respectively. Within the limitations of the present study, it was found that light-curing composite resins with higher energy density was beneficial to acquiring higher microhardness values and lower coefficients of thermal expansion.  (+info)

Photo-activation of the hydrophobic membrane probe 1, 5 iodonaphthylazide (INA) by irradiation with UV light (310-380 nm) results in the covalent modification of transmembrane anchors of membrane proteins. This unique selectivity of INA towards the transmembrane anchor has been exploited to specifically label proteins inserted in membranes. Previously, we have demonstrated that photo-activation of INA in enveloped viruses resulted in the inhibition of viral membrane protein-induced membrane fusion and viral entry into cells. In this study we show that photo-activation of INA in various cell lines, including those over-expressing the multi-drug resistance transporters MRP1 or Pgp, leads to cell death. We analyzed mechanisms of cell killing by INA-UV treatment. The effects of INA-UV treatment on signaling via various cell surface receptors, on the activity of the multi-drug resistance transporter MRP1 and on membrane protein lateral mobility were also investigated.

Some of the results come as a surprise: contrary to expectations, the reaction rate is not so much limited by the concentration of the molecules in solution, but decisively by the permeability of the nanoreactors shell. This is extremely interesting since chemists today can often fine tune or even switch the permeability of these shells to specific molecules via variations in temperature or other parameters, explains co-author Dr. Won Kyu Kim.. Photo-activation taken into account. The new model is a big step forward from the older theory done many decades earlier that could handle only one molecule. Our model is applicable to research on energy materials, and it can even take into account photo-activation of one of the molecules at the shell by sunlight, Dzubiella states. He has achieved with this work one of the goals of his European Research Council (ERC) Consolidator Grant (2015-2020).. ...

Light-emitting diodes (LEDs) come in many varieties and with a wide range of radiation patterns. We propose a general, simple but accurate analytic representation for the radiation pattern of the light emitted from an LED. To accurately render both the angular intensity distribution and the irradiance spatial pattern, a simple phenomenological model takes into account the emitting surfaces (chip, chip array, or phosphor surface), and the light redirected by both the reflecting cup and the encapsulating lens. Mathematically, the pattern is described as the sum of a maximum of two or three Gaussian or cosine-power functions. The resulting equation is widely applicable for any kind of LED of practical interest. We accurately model a wide variety of radiation patterns from several world-class manufacturers.. ©2008 Optical Society of America. Full Article , PDF Article ...

The A1U10 group showed significantly lower mean hardness than the other two groups (A1U20 and A1U40) for the U surface of this composite resin shade (A1) (£0.05). At the L surface of A1 shade a significantly higher mean hardness was found at 40 s irradiation time (A1L40) than for the A1L10 and A1L20 groups, which means that values were also statistically different (p£0.05). Both surfaces (U and L) of A3 shade composite revealed significantly greater mean hardness values at 40 s curing time, followed by the 20-s and the 10-s curing time groups (p£0.05). Statistically significant differences were found between U and L surfaces of each composite shade-IT combination (p=0.0001) and among the irradiation times of same shade-surface combination (p=0.0001), except between A1U20 and A1U40 groups. DISCUSSION. The polymerization of light-cured composite resins starts and is sustained when the rate of delivery photons from the source of light is sufficient to maintain the photo-absorbing compound, ...

We evaluated the effect of different light combinations on powdery mildew resistance and growth of melon seedlings. Light-emitting diodes were used as the light source and there were five light combinations: white light (420-680 nm); blue light (460 nm); red light (635 nm); RB31 (ratio of red and blue light, 3: 1); and RB71 (ratio of red and blue light, 7: 1). Compared with other treatments, blue light significantly decreased the incidence of powdery mildew in leaves of melon seedlings. Under blue light, H2O2 showed higher accumulation, and the content of phenolics, flavonoid and tannins, as well as expression of the genes involved in synthesis of these substances, significantly increased compared with other treatments before and after infection ...
A light-reflective anisotropic conductive paste is used as an anisotropic conductive paste when a light-emitting device is produced by flip-chip mounting a light-emitting element such as a light-emitting diode element (LED) on a wiring board. The light-reflective anisotropic conductive paste includes light-reflective insulating particles, in order to improve light emission efficiency without providing, in the LED, a light-reflecting layer that causes an increase in manufacturing cost. With the light-reflective anisotropic conductive paste, a reduction in bonding strength of the light-emitting element to the wiring board in a high-temperature environment can be suppressed, and a reduction in conduction reliability after a TCT can also be suppressed. In the light-reflective anisotropic conductive paste, conductive particles and the light-reflective insulating particles are dispersed in a thermosetting resin composition. The thermosetting resin
Intense room temperature emission at 3.7 mu m is reported from light-emitting diodes (LEDs) which contain ten InAsSb/InAs type II multi quantum wells grown by molecular beam epitaxy. Interpretation of the spectra revealed the existence of two confined heavy-hole states with emission peaks of 0.33 and 0.37 eV at 4 K. Analysis of the temperature dependence of the electroluminescence shows that emission occurred predominantly from the excited heavy-hole state at high temperatures. At room temperature, the devices produced a quasi-cw power of 12 mu W at 100 mA injection current corresponding to an internal quantum efficiency of 2.2%.. ...

Abstract: Proponents for sustainable alternative lighting and display options advocate for organic light-emitting diodes (OLEDs), particularly polymer-based organic light-emitting diodes (P-OLEDs), because of their potential for low-cost fabrication, more versatile device formats and lower power consumption compared to traditional options. Here, an economic, energy and CO2 emissions assessment is carried out for four different laboratory-scale, blue-emitting P-OLED device architectures: bottom-emitting conventional; bottom-emitting inverted; top-emitting conventional; and top-emitting inverted. Additionally, comparisons with a standard, commercial-scale, blue inorganic light-emitting diode (LED) device architecture are made. The various P-OLED device architectures are investigated due to their potential to increase operational lifetime (inverted) and light out-coupling efficiency (top-emitting). The following metrics are used in this assessment: device cost per area; yearly operating cost; ...

Abstract from Ellen Bruzells lecture at symposium MED-10 Dentistry. (Organized by Ellen Bruzell). ESP-IUPB World Congress, Light & Life, Barcelona, Spain. August 25-30. 2019.. Dental personnel encounter a number of optical sources emitting a broad spectrum of wavelengths. Along with the usefulness, to various extents, of optical radiation in treatment and diagnostics, comes the risk of radiation exposure to the operators eyes and the patients oral tissues. The presentation will cover the involuntary and voluntary use of different light sources. The curing light used for photopolymerisation of dental materials is an everyday procedure in the clinic. Curing lights have evolved from emitting moderate intensities of UV to high intensity blue light LEDs of several watts per centimeter squared. Dental bleaching procedures combined with light is a controversial topic. It is debated whether the light improves the efficiency. Thereby, the justification of the use is questionable. The bleaching ...
