Restorations will be placed on four primary molar teeth with occlusal caries, in a split mouth design. 100 patients will be included in the study. The teeth will be randomized into four groups according to the restorative materials.. Group 1: SDF (Riva Star) + Giomer (Beautifil II, (Shofu Dental, Tokyo, Japan) Group 2: Giomer (Beautifil II, (Shofu Dental, Tokyo, Japan) Group 3: SDF (Riva Star) + GIC (Equia Forte, GC, Japan) Group 4: GIC (Equia Forte, GC, Japan). The restorations will be evaluated clinically at baseline and 6., 12., 18., 24. months and radiologically at 6., 12. and 24. months. The modified US Public Health Service criteria (secondary caries, marginal integrity, marginal discoloration and retention) will be used for clinical evaluation of restorations. Intra-oral photos will be taken directly after treatment and at control appointments.. The data will be analysed statistically using Wilcoxon test, chi square test and the Kaplan-Meier survival method will be used to estimate ...

Chelates need to have single bonds and lone pairs in their structures to be able to surround a TM in a ring shape. You can see that the four acetates in this structure are bonded to the N atoms with single bonds, and the N atoms have lone pairs. This single C-N bond will allow the molecule to rotate, and the lone pairs on the Ns will bond to a TM like Co2+, making the compound a chelate ...

InChI requires a little more explanation: 1S is version 1 of Standard InChi (more about that later). C2H6 is the empirical formula and tells you that the first two atoms are C atoms. c1-2 means that atom 1 and 2 are connected. h1-2H3 means that atom 1-2 each have 3 H atoms. Programs that read SMILES strings are smart enough to know that this means that the two C atoms are connected by a single bond ...

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, ...

INTRODUCTION. Light-cured composite resins are being more used specially because they are aesthetically advantageous and enable to be polymerized by physical and chemical activators8,30. However, the crucial point to be reached during restorative dentistry procedures with composite resins is to obtain satisfactory restorations with an adequate light activation technique24.. Composites consist mainly of filler particles and a resin matrix based on different monomers6. Currently, the most widely marketed composite resins are based on the polymerization of bisphenol A glycol dimethacrylate (Bis-GMA) and urethane dimethacrylate (UDMA)25. The curing process occurs in the organic matrix where there is a monomer-polymer conversion through an activation mechanism8. However, an insufficient degree of conversion directly affects the physical properties and chemical stability of material8. Polymers used in the composition of composite resins may absorb water and chemicals from the oral environment ...

N2 - Self-assembled nanolayering structures have been reported in resin-dentin interfaces created by adhesives that contain 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). These structures have been hypothesized to contribute to bond durability. The objective of the present study was to determine the extent of nanolayering in resin-dentin interfaces after application of commercialized 10-MDP-containing self-etch and universal adhesives to human dentin. Seven commercialized adhesives were examined: Adhese Universal (Ivoclar-Vivadent), All-Bond Universal (Bisco, Inc.), Clearfil SE Bond 2, Clearfil S3 Bond Plus, Clearfil Universal Bond (all from ...

BackgroundLight curing of resin composite is associated with a thermal rise that may have harmful effect on the health of the vital pulp. In addition, desirable polymerization is important to achieve mechanical properties and clinical function. The purpose of this in‑vitro study was to compare the thermal rise under normal dentin during photopolymerization and degree of conversion (DC) of bulk fill and conventional resin composite using continuous high‑ and soft‑start mode.Materials and MethodsIn this in‑vitro study, Cl I cavities with a dimension of 4 mm × 4 mm × 4 mm and remaining dentin thickness of 1 mm were prepared on 56 extracted human molars. The temperature rise during the light curing of conventional resin composite (Tetric N Ceram, Ivoclar Vivadent) by incremental filling technique and bulk‑fill resin composite (Tetric N Ceram Bulk Fill, Ivoclar Vivadent) by bulk‑filling technique were measured with a K‑type thermocouple wire. DC of both resin composites was measured

Dental adhesive system formulations fundamentally contain resin monomers, polymerization initiators, inhibitors or stabilizers, solvents and sometimes inorganic fillers . According to their chemical structures, these components may exhibit hydrophobic or hydrophilic behavior . The hydrophilic components, such as 2-hydroxyethylmethacrylate (HEMA), are required to increase monomer infiltration into wet and demineralized dentin . However, the hydrophobic components used in these materials, such as bisphenol A glycidyldimethacrylate (Bis-GMA), are known to be responsible for enhancing the mechanical properties of the formulation and its compatibility with restorative composites or resin cements . Resin monomer infiltration into the spaces around exposed collagen fibrils depends on the results of dentin demineralization before hybrid layer formation . This interface must exhibit bond strength values that are sufficiently high to counteract the stresses generated by polymerization shrinkage and ...

NAFEMS Focus on Composites GLASGOW, UK, JANUARY 12TH 2010: In response to a recent upsurge of interest in composites analysis, NAFEMS, the International Association for the Engineering Analysis Community, has put together a series of events focusing on the subject, to give NAFEMS Members and the analysis community in general the opportunity to learn more about this topic, and share experiences with fellow analysts. Many designs now use composite structures or components, taking

Arithmetic operations are performed on composite operands that include plural component data items. The operations obtain valid results even though the operations would ordinarily produce inter-component signals, such as carry or borrow signals or a shifted bit, causing invalid results. For example, the component data items can be pixel values or other data relating to pixels in an image. Instructions on a storage medium can be accessed and executed by a processor to obtain valid results despite intercomponent signals. Or special circuitry, such as gating circuitry or a mask register, can be used to prevent inter-component signals. Components in composite operands can be separated by buffer bits that are cleared or set to ensure valid results. Values of components can be biased before an operation to obtain valid results.

Streambanks can be a significant source of sediment and phosphorus to aquatic ecosystems. Although the streambank-erosion routine in the Soil and Water Assessment Tool (SWAT) has improved in recent versions, the recently developed routine in SWAT 2012 has undergone limited testing, and the lack of site or watershed specific streambank data increases the uncertainty in the streambank-erosion predictions. There were two primary objectives of this research: (1) modify and test the 2012 SWAT streambank-erosion routine on composite streambanks, and (2) compare SWAT default and field-measured channel parameters and assess their influence on predicted streambank erosion. Three modifications were made to the SWAT 2012 streambank-erosion routine: (1) replacing the empirical effective shear stress equation with a process-based equation, (2) replacing bankfull width and depth measurements with top width and streambank height, and (3) incorporating an area-adjustment factor to account for non-trapezoidal ...
