TY - JOUR. T1 - Water-dependent interfacial transition zone in resin-modified glass-ionomer cement/dentin interfaces. AU - Tay, F. R.. AU - Sidhu, S. K.. AU - Watson, T. F.. AU - Pashley, D. H.. PY - 2004/8. Y1 - 2004/8. N2 - The function of the interfacial transition zone (absorption layer) in resin-modified glass-ionomer cements bonded to deep dentin remains obscure. This study tested the hypotheses that the absorption layer is formed only in the presence of water derived from hydrated dentin and allows for better bonding of resin-modified glass-ionomer cements to dentin. Ten percent polyacrylic acid-conditioned, hydrated, and dehydrated deep dentin specimens were bonded with 2 resin-modified glass-ionomer cements and sealed with resins to prevent environmental water gain or loss. A non-particulate absorption layer was identified over hydrated dentin only, and was clearly discernible from the hybrid layer when bonded interfaces were examined with transmission electron microscopy. This layer ...

There was no statistical difference in the shear bond strength of ...

The purpose of this study was to quantify and compare the amount of water absorbed by six commercially available resin-modified glass ionomer cements and to investigate the possible influence of time and resin content on water sorption. The materials evaluated included Variglass used as a restoration, base and liner; Fuji II LC; Fuji Liner; Vitrebond; Vitremer and Photac-Bond. Z100, a composite resin, was used as control. All specimens were manipulated according to manufacturers instructions and then subjected to a water sorption test based on the ISO 4049 requirements. Storage in water was further extended to 1 month to evaluate the effects of time and indirectly cement maturity on water sorption. Data were subjected to one-way ANOVA and Duncans test at 0.05 significance level. Results show that the composite resin control had significantly less water sorption than all the resin-modified polyalkenoate cements evaluated. Variglass when used as a base or restorative had the least water sorption ...

Glass ionomer cements (GICs) are used by oral health professionals on exposed root surfaces to protect against demineralisation and tooth sensitivity. Researchers in the Oral Health CRC sought to develop an improved functional GIC capable of remineralising surrounding areas of tooth enamel. The commercial outcome of this research is Fuji VII-EP (Extra Protection) - a novel glass ionomer cement enhanced with 3% CPP-ACP (RecaldentTM) now manufactured and distributed by GC Corporation. Studies in the Oral Health CRC have found that Fuji VII-EP releases calcium, phosphate and fluoride ions into the tooth and increases protection against demineralisation. Further studies in the Oral Health CRC are exploring the antibacterial benefits of Fuji VII-EP.. Fuji VII-EP is available to dental professionals in the USA and New Zealand. It is distributed by GC Corporation. More information.. ...

|i|Objective|/i|. To reduce secondary caries, glass ionomer luting cements are often used for cementing of indirect restorations. This is because of their well-known antimicrobial potential through the release of fluoride ions. The aim of this |i|in vitro|/i| study was to investigate the antimicrobial effect of five dental luting cements which were based on glass ionomer cement technology. |i|Methods|/i|. Five different glass ionomer based luting cements were tested for their antimicrobial effects on |i|Streptococcus mutans|/i| in two different experimental setups: (i) determination of colony-forming units (CFUs) in a plate-counting assay; (ii) live/dead staining (LDS) and fluorescence microscopy. All experiments were conducted with or without prior treatment of the materials using sterilized human saliva. Antimicrobial effects were evaluated for adherent and planktonic bacteria. Bovine enamel slabs (BES) were used as negative control. BES covered with 0.2% chlorhexidine (CHX) served as positive

Composite resin is a suitable restorative material to restore an existing failed restoration, however it is unsuitable to restore a carious lesion due to the large amount of remineralizable dentin required to achieve a reliable adhesive base.. Glass ionomer cements (GIC) will adhere to caries affected dentin, minimizing the amount of tooth removal required to restore the tooth. Glass ionomer cement can be used as a restorative material in its own right or as a base for a composite resin overlay (sandwich restoration) where the remaining tooth structure is unsupported and requires a bonded composite to maintain its structural integrity.. For the following reasons glass ionomer cements are the material of choice for treating an active carious lesion:. • The weak bond strength of glass ionomer cement to sound and caries affected tooth structure does not affect the integrity of the restoration as there is not the polymerization shrinkage stress associated with composite resins.. • Glass ionomer ...

Ketac™ Molar Quick material is a bulk-fill, packable and fast-setting conventional glass ionomer. High compressive strength and marginal integrity make it a glass ionomer of choice for posterior restorations.Refill includes 50 capsules in shade A2.

The purpose of this study was to determine the failure mode of a posterior composite resin bonded to a glass-ionomer cement that was treated with and without a cationic vinyl functional silane coupling agent while the etch times were varied. Bond failure occurred at the glass-ionomer cement-composite resin interface (adhesive failure) in specimens that were not etched and when no coupling agent was used. When the samples were etched for 5, 15, or 30 seconds, approximately 50% failed within the glass-ionomer cement (cohesive failure). The use of the coupling agent produced a failure mode of 80% to 100% within the glass-ionomer cement. With a 15-second etch, the coupling agent produced 100% failure within the glass-ionomer cement, while only 50% of the samples without the coupling agent failed within the glass-ionomer cement. With a 30-second etch, all the samples treated with the coupling agent failed within the glass-ionomer Cement, while only 60% of the samples not treated with the coupling ...

A commercially available dental Glass Ionomer Cement (GIC) was studied after setting at room temperature (300 K) to understand its DC electrical conductivity, dielectric and thermal properties. The dental GICs are supposed to have free mobile charge carriers like F- ions. Interestingly this material loses its conductivity above 80°C and behaves like a non-polar substance. The frequency dependent dielectric studies also indicate the loss of mobile charge carriers in the samples annealed at 80°C. The DSC and TGA studies indicate that the material loses H2O exothermically at 100°C. This is attributed to the onset of a secondary setting reaction.

Management of deep carious lesions and the associated histopathological pulpal changes is important for caries management in operative dentistry. The pulp requires protection from further bacterial invasion from the carious process, thermal / electrical conduction (depending on the conductivity of the restorative material placed upon it) and chemical protection from the overlying restorative materials. An important function of a therapeutic lining material is to stimulate the pulp odontoblasts to lay down reparative dentine and promote remineralization of existing dentine; thus encouraging the dentine-pulp complex and eventually, the carious lesion, to heal.

GC 1 Glass ionomer cement is high strength bases used primarily for permanent cement, as a base, and as a Class V filling material.

While stronger amalgam fillings may be preferred where our back teeth are involved, dentists opt for composite fillings for our front teeth, because they can do more with them, and can tint them to match the color of your other teeth. There are three main types of composite fillings, namely composite fillings, glass ionomer cements and dental compomers - each have their own applications, which you should discuss with your service provider before they proceed.. Composite Fillings (also known as white fillings, and which replaced precious metal fillings in the 1960s) include a mixture of tooth colored plastic and glass silicone for strength. They are used for more than filling cavities, and can also help re-shape and re-color a disfigured tooth.. Glass Ionomer Cements are a more recent dental solution with a wider range of applications than basic composite fillings. While they can be used in place of these, other possibilities include attaching orthodontic devices such as bridges, pins, posts and ...

Ionomers - Glass ionomers are tooth-colored materials made of a mixture of acrylic acids and fine glass powders that are used to fill cavities, particularly those on the root surfaces of teeth. Glass ionomers can release a small amount of fluoride that help patients who are at high risk for decay. Glass ionomers are primarily used as small fillings in areas that need not withstand heavy chewing pressure. Because they have a low resistance to fracture, glass ionomers are mostly used in small non-load bearing fillings (those between the teeth) or on the roots of teeth. Resin ionomers also are made from glass filler with acrylic acids and acrylic resin. They also are used for non-load bearing fillings (between the teeth) and they have low to moderate resistance to fracture. Ionomers experience high wear when placed on chewing surfaces. Both glass and resin ionomers mimic natural tooth color but lack the natural translucency of enamel. Both types are well tolerated by patients with only rare ...

We have used fibrous carbon materials as polymer electrolyte fuel cell (PEFC) electrodes. We have examined the influence of the ionomer/carbon ratio on the performance of the PEFCs. The Marimo carbon is a kind of carbon with a spherical shape, and consists of carbon nanofilaments. Fibrous carbon materials have large specific surface areas without fine pores. The reactant gases and generated water can easily diffuse among the nanofilaments. The ionomer plays two roles; one is a proton transfer activity, and the other is binding the catalyst electrodes. An excess ionomer interferes with the diffusion of gases. The ionomer/carbon ratio should affect the performance of the PEFC, especially at a high current density.

The purpose of this in vitro study was to examine the effect of various powder-liquid ratios of an experimental resin-modified glass-ionomer polymer cement on dye penetration when the cement was used as a pit and fissure sealant. Eighty extracted human third molars were randomly assigned to one of four pit and fissure sealant conditions; a resin-based sealant or one of three variations in powder-liquid rations (1.4:1.0, 1.8:1.0, and 2.0:1.0) of an experimental, light-activated, resin-modified glass-ionomer cement. After sealant placement the teeth were thermocycled and immersed in methylene blue dye. The teeth were sectioned, and the extent of the dye penetration along the sealant-enamel interface was measured linearly. The resin-sealed occlusal fissures showed statistically significantly less dye penetration than did the three powder-liquid ratios of the experimental resin-modified glass-ionomer-cement sealant ...

Aim: The aim of this study was to investigate the interaction of a high viscosity glass ionomer cement (GIC) and a composite resin with caries affected dentin and to determine the remineralization levels. Materials and methods: In a split mouth design 24 GIC and composite resin atraumatic restorative treatment restorations were made in vivo and the teeth were collected after 2 years and subsequently sectioned and examined using Vickers microhardness test; the latter was performed starting from the dentin surface adjacent to the restoration. Repeated Measure ANOVA and Bonferroni statistical methods were used for data analysis. Results: The microhardness adjacent to the GIC restorative material resulted to be significantly higher. Conclusion: GIC resulted to be a better restorative material for the remineralization of caries affected dentin, though further studies are necessary for the corroboration of this finding. The GIC restored primary molar dentin had a higher level of remineralization and ...

The purpose of this in vitro study was to evaluate the cariostatic potential of an ACP containing orthodontic bonding agent adjacent to brackets. Sixty human molars were randomly distributed into: ACP adhesive, resin modified glass ionomer cement (RMGIC), and conventional composite resin groups (N=20 each). Brackets were bonded following the manufacturers instructions. Tooth enamel through a 2mm window around the brackets was cycled in demineralization (6 hrs) and remineralization (18 hrs) solutions. After 14 days, teeth embedded in resin and were sectioned. Knoop indentations were performed to determine enamel hardness. There were no statistically significant differences between the control and experimental groups. However, both Fuji Ortho LC (RMGIC), and Aegis Ortho (ACP) showed a trend toward a reduction in

This article aims to update the existing systematic review evidence elicited by Mickenautsch et al. up to 18 January 2008 (published in the European Journal of Paediatric Dentistry in 2009) and addressing the review question of whether, in the same dentition and same cavity class, glass-ionomer cement (GIC) restored cavities show less recurrent carious lesions on cavity margins than cavities restored with amalgam. The systematic literature search was extended beyond the original search date and a further hand-search and reference check was done. The quality of accepted trials was assessed, using updated quality criteria, and the risk of bias was investigated in more depth than previously reported. In addition, the focus of quantitative synthesis was shifted to single datasets extracted from the accepted trials. The database search (up to 10 August 2010) identified 1 new trial, in addition to the 9 included in the original systematic review, and 11 further trials were included after a hand-search and

Maximum stress at which material recovers completely. Conclusions: Results: Crosshead rate only significantly affected compressive proportional limit and … You care trying to capture the details and dimensions of the hard and soft tissues of a dental arch. Renson CE, Braden M. The experimental determination of the rigidity modulus, Poissons ratio and the elastic limit in shear of human dentin. If the value of external force is such that it exceeds the elastic limit, than the body will not completely regain its original position. Results: The ceramic posts were very stiff and strong, with no plastic behavior. Repetitive torsional loading with a gradually increasing rotational angle reduced the torsional resistance compared with the single rotation motion. There fore, for all practical 33. purposes, the proportional limit and elastic limit represent the same stresses within the structure and terms are used inter changeably. Elastic moduli of polycarboxylate and glass ionomer cements increased ...

Darkening of decayed and demineralized sites occurs as the lesion arrests. Non-lesioned tooth structure does not stain with the application of silver diammine fluoride. Similar to the treatment of eroded and hypersensitive dentin, the treated area can be restored using glass ionomer or with a sandwich restoration of both glass ionomer and composite.. Riva Star should not be diluted in an attempt to reduce discoloration. Studies have shown that diluted solutions may not be effective for caries arrest.. Ionic silver adsorbs onto almost any protein surface and is especially tenaciously bound to denatured proteins. This accounts for the specificity to carious collagen over normal collagen, but both will stain. The differentiator between these stains is that with SDF use intrinsic pigmentation of a carious lesion occurs and surface protein staining occurs primarily on healthy tissue. These oxides are bound to the tissue and dont wash or polish away. Therefore, the blackened lesion retains its dark ...

Methods: Ten cylindrical specimens of three commercial glass ionomers cements (Vidrion R - S.S. White, Maxxion R - FGM and Vitromolar DFL) were prepared (n=30) without surface finishing or protection. Twenty-four hours after preparation, the surface roughness measurements were obtained as the mean of three readings of the surface of each specimen by profilometry. The roughness values (Ra, μm) were subjected to one-way ANOVA and Tukey′s test ( ...
