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.

A geometrical-optical technique is used to predict the changes in the slope of the eccentric-photorefraction intensity profiles as a function of refractive state. We investigate how the intensity profiles vary with refractive state for different light source configurations and monochromatic aberrations in the eye. The best possible light source configuration extends from zero eccentricity (to increase sensitivity and reduce the dead zone) to a high eccentricity (to increase the working range). An advantage of using the extended light source is that the intensity profile of the eccentric-photorefraction reflex is more linear for extended sources than for point light sources. It is also shown that the change in slope with refractive state is dependent on pupil size. Furthermore, when asymmetric aberrations are present, the change in intensity profile slope with refractive state is dependent on the circumferential position of the light source, but this dependence can be resolved by averaging slope ...

Electron blocking layers (EBLs) are commonly used to reduce the leakage current in modern multi-quantum well (MQW) InGaN light-emitting diodes (LEDs). We study the effect of the EBL and doping on the operation and efficiency of LEDs. We simulate both conventional MQW LEDs with AlGaN EBL, LEDs with quaternary AlInGaN EBL and LEDs without EBL. We show that the elimination of the polarization charges at the EBL interface greatly enhances the injection efficiency and that the hole injection in MQW lattice can be optimized by doping. The efficiency droop limiting the high power operation is also analyzed to determine the underlying mechanisms in the simulated MQW structures. Based on these results, we discuss the measures to increase the overall efficiency MQW structures ...

A flexible piston rod includes a piston and a row of elements, each having top, bottom, and lateral surfaces, the top surface of one element being connected to the bottom surface of an adjacent element by a hinge that allows the two adjacent elements to pivot from a first position, where a portion of the top surface of one element abuts a corresponding portion of the bottom surface of the adjacent element and corresponding to a rectilinear, relatively stiff configuration of the piston rod, to a second position wherein the top surface of one element is spaced from the bottom surface of the adjacent element and corresponding to a curved configuration of the piston rod. The lateral surface of each element has first and second mutually-opposed cylindrical surface portions incorporating a thread for meshing with a corresponding thread of an actuator for displacing the piston rod longitudinally.
Considering the fact that during phototropism a lateral auxin gradient with its maximum on the shaded side is formed, the question arises how it is possible that such a gradient is established. Here, it is of special interest why the maximum of the gradient is located on the shaded side since the original blue light stimulus is applied to the opposite side and photo-activation seems to be positively fluence correlated. Still, one can argue that the light absorption of a tissue like a dark grown hypocotyl (with a diameter of about 250μm) hardly absorbs any light but then one would need to question why a gradient is formed at all. In the course of this project, it is planned to investigate this gradient formation relying on both, experimental techniques as well as computational modeling, collaborating with the groups of Richard Smith and Christian Fankhauser as part of the Plant Growth project from SystemsX.ch. ...

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
I have seen some of these lights (for illuminating driveways etc) and am ,wondering "why not?" I can buy one of these units for 9 (~$15), whereas to ,equip my tank with flourescents, ballasts etc would cost me well over 100 ,($150). Is there an "absolutely not" type reason? You can use these (known as low voltage dichroics), but the standard ones have a colour temperature that is generally considered to low for good plant growth, around 3000K-2500K. There is a new low voltage dichroic on the market that has a colour temperature of 4700K, CRI 87 that is a daylight lamp that does look very good on a planted tank. I hve seen them available for between AU$13-AU$20. Marque APD - ANGFA(NSW) - Sydney ...
All-inorganic perovskite materials, i.e. cesium lead halide (CsPbX3 (X = I, Br, Cl)), have attracted much attention in the application of photoelectronic devices, especially in solar cells and light-emitting diodes (LEDs). However, the solubility issue of CsPbX3 restricts their utilization in solution-proces
Blue light-emitting diodes (LEDs) offer new opportunities in practical solid-state lighting and could play a significant role in reducing global energy consumption.

The influences of fluorescent dye doping on the magnetoelectroluminescence in tris (8-hydroxyquinolato) aluminum (Alq3)-based organic light-emitting diodes have been investigated systematically by varying the dopant concentrations and its energy band gap. Our results show that the decrease in electroluminescence intensity at high magnetic field, which survives only at low temperatures for pure Alq3-based devices, persists in dye-doped devices even at room temperature. This is explained here as the result of magnetic field dependent triplet-triplet annihilation process, in which the triplet excitons trapped on the dye molecules play the most important role ...

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 ...

I have a gunite indoor pool which was built 1997. I have two old underwater halogen lights which keep leaking and attempting to replace the o-ring while replacing the halogen lamp bulb is no longer working. I had a pool contractor come out and look at replacing these but the general approach is to pull out the power supply cord and the fish through a new unit. The problem is that the way these were installed resulted in a very long power supply cord (~30 ft) so this contractor was not sure the approach would work. Does anyone have a suggestion of how to either repair or replace these under these conditions ...

TY - JOUR. T1 - Organic light-emitting diodes with an electro-deposited copper(I) thiocyanate (CuSCN) hole-injection layer based on aqueous electrolyte. AU - Tsai, Chi Ting. AU - Gottam, Sandeep Reddy. AU - Kao, Po Ching. AU - Perng, Dung Ching. AU - Chu, Sheng Yuan. PY - 2019/10. Y1 - 2019/10. N2 - Copper(I) thiocyanate (CuSCN) has been drawing much attention in optoelectronics due to its exceptional optical and electrical properties, as well as its processing versatility. The first organic light-emitting diodes (OLEDs) integrated with electro-deposited CuSCN crystalline thin films based on aqueous electrolyte were fabricated. With precisely tuned deposition parameters, the CuSCN thin films with satisfactory surface roughness and sufficient grain density were realized. We found that the driving voltage (voltage at a current density of 100 mA/cm2) and turn-on voltage of OLEDs using CuSCN as the hole injection layer (HIL) can be reduced by 1.41 and 1.79 V, respectively, compared with devices ...

0094] As described above, in the case where the track direction a of the structure bodies 3 and the extending direction (X axis direction) of the long sides of the imaging region A1 have a parallel relationship, as shown in FIG. 6B, it is preferable that (a) the structure body 3 be formed as a cone of which the bottom surface has an elliptical shape including a long axis and a short axis, and (b) the direction of the long axis of the bottom surface of the structure body 3 correspond with the track direction a. (a) The structure body 3 is formed as a cone of which the bottom surface has an elliptical shape including a long axis and a short axis, and thereby the track pitch Tp can be reduced as compared with a case where the bottom surface of the structure body 3 is formed to be circular. Thereby, the light beam L0 from a light source such as a light spot can be scattered so as to be further distant from the optical axis 1 as compared with a case where the bottom surface of the structure body 3 is ...

ISSN 1980-6523. http://dx.doi.org/10.1590/S1980-65232011000300010.. PURPOSE: The use of different light sources as an adjunct to in-office bleaching has been questioned. Thus, the aim of this study was to evaluate the color changes of teeth after application of bleaching techniques with different products, with and without activation by a LED-laser system. METHODS: Twenty-four bovine teeth surfaces were submitted to three bleaching techniques with two commercially available 35% hydrogen peroxide bleaching agents (n=8). The specimens were immersed in red wine for 48 h at 37°C and submitted to the bleaching techniques. Color changes were measured before and after staining as well as immediately after and 24 h after the bleaching treatments, with two different methods of color evaluation, software ScanWhite V1.1 and ...

Caged antisense oligodeoxynucleotides (asODNs) are synthesized by linking two ends of linear oligodeoxynucleotides using a photocleavable linker. Two of them (H30 and H40) have hairpin-like structures which show a large difference in thermal stability (delta T(m) = 17.5 degrees C and 11.6 degrees C) comparing to uncaged ones. The other three (C20, C30 and C40) without stable secondary structures have the middle 20 deoxynucleotides complementary to 40-mer RNA. All caged asODNs have restricted opening which provides control over RNA/asODN interaction. RNase H assay results showed that 40-mer RNA digestion could be photo-modulated 2- to 3-fold upon light-activation with H30, H40, C30 and C40, while with C20, RNA digestion was almost not detectable; however, photo-activation triggered > 20-fold increase of RNA digestion. And gel shift assays showed that it needed > 0.04 mu M H40 and 0.5 mu M H30 to completely bind 0.02 mu M 40-mer RNA, and for C40 and C30, it needed > 0.2 mu M and 0.5 mu M for 0.02 ...
Relating the functional properties of neurons in an intact organism with their cellular and synaptic characteristics is necessary for a mechanistic understanding of brain function. However, while the functional properties of cortical neurons (e.g. tuning to sensory stimuli) are necessarily determined in vivo, detailed cellular and synaptic analysis relies on in vitro techniques. Here we describe an approach that combines in vivo calcium imaging (for functional characterization) with photo-activation of fluorescent proteins (for neuron labeling), thereby allowing targeted in vitro recording of multiple neurons with known functional properties. We expressed photo-activatable GFP rendered non-diffusible through fusion with a histone protein (H2B-PAGFP) in the mouse visual cortex to rapidly photo-label constellations of neurons in vivo at cellular and subcellular resolution using two-photon excitation. This photo-labeling method was compatible with two-photon calcium imaging of neuronal responses to visual

The optimal Mg co-doping selectively enhanced a specific emission site and contributed to a photoluminescence (PL) intensity increase of more than one order of magnitude. From the ratio of PL integrated intensity at 25 K to that at 300 K, the PL efficiency was determined to be as high as 77%. On the basis of these results, Eu doped GaN based LEDs were fabricated. Clear rectification characteristics with a turn-on voltage of 3.2 V were observed and a pure red emission was observed by the naked eye at room temperature. These results suggest that Eu and Mg doped GaN is expected to be utilized for realizing new nitride-based light-emitting devices ...

A surface foam diffuser system having a first nozzle disposed above a top surface of the at least partially liquid contents, a splash plate positioned adjacent to the first nozzle outlet, and a second nozzle disposed below the top surface of the at least partially liquid contents is disclosed for suppressing foaming in large processing tanks. The system nozzles each have an inlet for receiving pressurized liquid and an outlet for ejecting a liquid stream into the tank, the depth of the second nozzle and the direction of the liquid stream there from being such that rotation of the top surface is facilitated. The spray of the first nozzle, as dispersed by the splash plate, reduces foam on at least a portion of the top surface, with the rotation of the top surface allowing each portion of the top surface to eventually fall within the reducing spray.
Dave - Thats to do with the way your brain is attempting to interpret the colour information. Your brain attempts to take into account that different light sources actually look very different. If you have ever seen a photo taken inside with a camera which is an attempt to compensate for this - inside with normal incandescent bulbs, it looks incredibly yellow and your brain immediately tries to compensate for that. What youre actually seeing is the whole thing is actually looking different types of orange, different points of orange because theres only one colour.
Infrared spectrophotometry (IR) uses similar instrumentation to UV-vis spectrophotometry but it uses a different light source (infrared frequencies of ~1011 to 1014 Hz). The instrumentation consists of an infrared beam that is split into two identical beams (reference beam and analytical beam).. The analytical beam passes through the sample so that molecular vibrational absorption can occur. The intensity of the two beams are compared over the range 2.5 µm to 16 µm and plotted as a function of wavenumber (the reciprocal of the wavelength in cm-1). ...

We investigated light-emitting diodes consisting of an InGaAs/GaAs quantum well adjacent to a ferromagnetic δ〈Mn〉-layer. The magnetic field-dependent circular polarization obtained from both photo- and electroluminescence shows an unusual sign inversion depending on the growth parameters that can be explained by an interplay of the Zeeman splitting and Mn-hole interaction effects. Our results can help to understand the origin and control of the spin polarization on Mn doped GaAs structures, a fundamental step for the development of Mn-based spintronic devices. ...
TY - JOUR. T1 - MicroRNA expression analysis of human skin fibroblasts treated with high-fluence light-emitting diode-red light. AU - Mamalis, Andrew. AU - Koo, Eugene. AU - Tepper, Clifford G. AU - Jagdeo, Jared. PY - 2019/1/1. Y1 - 2019/1/1. N2 - Skin fibrosis is a chronic debilitating feature of several skin diseases that lead to characteristic increases in dermal fibroblast proliferation and collagen deposition through upregulation in components of the transforming growth factor beta (TGF-B)/SMAD pathway. In contrast to ultraviolet phototherapy, high-fluence light-emitting diode-generated red light (HF-LED-RL, 633 ± 15 nm) is a safe, economic and non-invasive therapy with in vitro evidence that supports modulation of the key cellular characteristics involved in the pathogenesis of skin fibrosis. Limited data exists pertaining to the effects of HF-LED-RL on human skin fibroblast microRNA (miRNA). Herein, we explored the effects of HF-LED-RL on fibroblast miRNA levels using RNA-seq and miRNA ...
Objective: To assess the influence of ormocer, nanofilled, nanoceramic, and microhybrid composite restorative systems on the fracture resistance of maxillary premolars with Class II mesio-occlusodistal (MOD) cavities. Method and Materials: Eighty-four sound maxillary human premolars were divided into six groups of 14 teeth each. Teeth in the first group were left intact and tested as unprepared positive controls. Teeth in the remaining five groups were prepared with MOD cavities. Teeth in one of the five groups were unrestored and tested as negative control. The remaining four groups were restored with an ormocer (Admira), a nanofilled composite (Filtek Supreme), a nanoceramic composite (CeramX mono), and a microhybrid composite (Tetric Ceram). All groups were stored in water at 37 C for 24 hours and thermocycled 500 times between 5 C and 55 C. The specimens were loaded occlusally in a universal testing machine using a metal sphere that contacted only the teeth on the cuspal inclines until ...

  • The light itself however can and does contribute to providing heat to the tooth. (blogspot.com)
  • Take a little more time, or at least move such a high powered light further back off the tooth and then slowly bring the light closer to your normal curing distance. (blogspot.com)
  • Before dental curing lights were developed, different materials were used as resin-based composite materials to be placed in a tooth. (factmr.com)
  • This dental material has good adhesive bond properties to tooth structure, allowing it to form a tight seal between the internal structures of the tooth and the surrounding environment. (wikipedia.org)
  • The acid produced from this metabolism results in the breakdown of tooth enamel and subsequent inner structures of the tooth, if the disease is not intervened by a dental professional, or if the carious lesion does not arrest and/or the enamel re-mineralises by itself. (wikipedia.org)
  • Pulpitis may be caused by dental caries that penetrate through the enamel and dentin to reach the pulp, or it may be a result of trauma, such as physical abuse of the tooth or thermal insults, including overheating from insufficiently cooled dental drills and use of dental curing lights. (wikipedia.org)
  • This is why people who have lost their dental innervation have a reduced healing ability and increased rate of tooth injury. (wikipedia.org)
  • Thank you for your insightful discussion explaining the importance of curing time related to polymerization heat build up and possible sensitivity. (blogspot.com)
  • Dental professionals need to opt for ideal dental curing lights as improper polymerization of materials can result into clinical failures, including marginal discoloration, de-bonding issues, and sensitivity. (factmr.com)
  • Indicated for use in both post and core dental build up procedures, the CoreRestore2 can create a solid and longer lasting composite core, with a short curing time. (kerrdental.com)
  • This core build up dental system includes CoreForms, which can assist in forming core shapes to reduce time and effort associated with the restoration. (kerrdental.com)
  • The ability to temporarily bond restorations, crowns, or bridges allows dentists the time they need to create more permanent restorations without sacrificing patient comfort and dental function. (kerrdental.com)
  • light , low light , getting brighter, flicker 4 :5-40 seconds curing time can be adjusted 5. (78wy.com)
  • The inventor of this system was not familiar with visible light curing chemistry at the time, and therefore selected UV chemistry, which was quickly replaced by blue, visible light curing chemistry. (blogspot.com)
  • The big difference between these high powered units and the typical units is that the material is forced to set all at once with no heat dissipation during the curing time. (blogspot.com)
  • Yes, taking a little more time to prevent heat build up, and to also insure a well cured material, is worth it. (blogspot.com)
  • You can select the right time for the different types of material you wish to cure, their speed of reaction and the clinical protocol you are following. (drkits.com)
  • Our dental cements are based on an innovative chemistry to optimize dental restorations for unmatched esthetics, adhesion and great versatility. (kerrdental.com)
  • Proper clinical procedure dictated that the student cleaned all surfaces of the curing light with a liquid, cold disinfectant (Dispatch, Clorox) between patients. (umich.edu)
  • The application of glass ionomer sealants to occlusal surfaces of the posterior teeth, reduce dental caries in comparison to not using sealants at all. (wikipedia.org)
  • Dental sealants were first introduced as part of the preventative programme, in the late 1960s, in response to increasing cases of pits and fissures on occlusal surfaces due to caries. (wikipedia.org)
  • They are lights which fall under the visible blue light spectrum and are delivered over a range of wavelengths which vary depending on the type of the device. (factmr.com)
