Marginal adaptation of commercial compomers in dentin cavity. (1/319)

The dentin cavity adaptation and setting characteristics of four commercial compomers were evaluated by measuring the wall-to-wall contraction gap width in the cylindrical dentin cavity and measuring the compressive strength for a maximum of 14 days after setting. The dentin cavity wall was pretreated by the dentin adhesives according to each manufacturer's instructions or the experimental contraction gap-free dentin bonding system. Complete marginal integrity was obtained in only one compomer and two resin composites which were combined with the experimental dentin bonding system. The compressive strength of two resin composites and two compomers ten minutes after setting was comparable to that after 14 days which indicated that the compomers exhibited setting characteristics as rapidly as the resin composite. It was concluded that a high efficacy dentin bonding system is required for commercial compomers to prevent gap formation during irradiation caused by the rapid setting shrinkage.  (+info)

A review of glass ionomer restorations in the primary dentition. (2/319)

Glass ionomer cements are tooth-coloured materials that bond chemically to dental hard tissues and release fluoride for a relatively long period. They have therefore been suggested as the materials of choice for the restoration of carious primary teeth. However, the clinical performance of conventional and metal-reinforced glass ionomer restorations in primary molars is disappointing. And although the handling and physical properties of the resin-modified materials are better than their predecessors, more clinical studies are required to confirm their efficacy in the restoration of primary molars.  (+info)

What is a "compomer"? (3/319)

"Compomers" are recently introduced products marketed as a new class of dental materials. These materials are said to provide the combined benefits of composites (the "comp" in their name) and glass ionomers ("omer"). Based on a critical review of the literature, the author argues that "compomers" do not represent a new class of dental materials but are merely a marketing name given to a dental composite.  (+info)

Ionogran in revision arthroplasty. (4/319)

Glass ionomer cement (Ionocem) was developed for use in bone surgery and is reported to be notably biocompatible. Between 1991 and 1994 we performed revision operations for aseptic loosening of arthroplasties of the hip on 45 patients using this material in its granulate form (Ionogran) mixed with homologous bone as a bone substitute. Of these 45 patients, 42 were followed up for a mean of 42 months. Early reloosening of the acetabular component has occurred in ten after a mean of 30 months. Histological examination showed large deposits of aluminium in the adjacent connective tissue and bone. Osteoblastic function and bone mineralisation were clearly inhibited. The serum levels of aluminium were also increased. The toxic damage at the bone interface caused by high local levels of aluminium must be seen as an important factor in the high rate of early reloosening. Our findings cast doubt on the biocompatibility of this material and we do not recommend continuation of its further use in orthopaedic surgery.  (+info)

Structure of bioactive glass and its application to glass ionomer cement. (5/319)

We prepared a new glass ionomer cement using bioactive CaO-P2O5-SiO2(-MgO) glass and investigated its setting process using FT-IR and MAS NMR analyses. The compressive strengths of the cements depended on the glass composition and a maximum strength of 33.3 +/- 4.7 MPa was obtained using cement with the glass composition of MgO:4.6, CaO:44.9, SiO2:34.2 and P2O5:16.3% in weight. FT-IR analysis showed that the COOH group in the polyacrylic acid decreased and carboxylate ion (COO-Ca2+) increased after the setting reaction. A broad signal appeared around -82 ppm in 29Si MAS-NMR spectra of the glass and a new signal corresponding to hydrated silica gel formation appeared around -102 and -111 ppm after setting. This suggests that Ca2+ was released from the glass powder to form carboxylate salt and that a degree of polymerization in the silicate network increased. The setting mechanism of the cement was found to be essentially the same as in conventional glass ionomer cement.  (+info)

Resin content in cement liquids of resin-modified glass ionomers. (6/319)

Qualitative and quantitative analyses were conducted on four kinds of resin-modified glass ionomer (RMGI) cement liquids, LC, LC II, LC III (hereinafter referred to as LCs) and VM, using HPLC and laser Raman spectroscopic methods. HPLC revealed that among the RMGI liquids LCs contain 31-32% HEMA (2-Hydroxyethyl methacrylate), and VM contains 18% of the same. The composition of RMGI cement liquids varied significantly between manufacturers. In Raman spectroscopic analyses, the spectra of liquids of various ratios of polyacrylic acid and HEMA were measured, and calculations were made on the peak intensity ratios of C=C stretch vibration to C=O stretch vibration, common in both HEMA and polyacrylic acid. The composition ratio of polycarboxylic acid to HEMA of commercial glass ionomer cements was assessed by the regression curve generated by a combination of peak intensity ratios and composition ratios. In addition, Raman spectroscopy was able to identity the differences in form of the methacryloyloxy group.  (+info)

Inhibition of carious lesions in vitro around gallium alloy restorations by fluoride releasing resin-ionomer cement. (7/319)

A new fluoride releasing resin-ionomer cement was used for bonding of gallium alloy restorations in vitro. Etching, priming, and fluoride releasing resin-ionomer cement were used in the experimental group (ARG), prior to placement of the gallium alloy restorations. Three different controls were used: gallium alloy only (G), no etching, fluoride releasing resin-ionomer cement, gallium alloy (RG), etching, priming, non-fluoride cement and gallium alloy (ACG). The mean shear bond strengths of ARG group to enamel and dentin were higher than those of the three control groups. Artificial secondary caries lesions around the restorations in the experimental group and the control groups were produced, using a strep. mutans culture. The microradiographs were examined for presence of a caries inhibition zone near the restoration. Caries inhibition zones were clearly detected around RG and ARG, but not around G and ACG. The results indicate that the fluoride releasing resin-ionomer cement provided good adhesion and caries inhibition in enamel and dentin.  (+info)

Setting shrinkage and hygroscopic expansion of resin-modified glass-ionomer in experimental cylindrical cavities. (8/319)

The effects of the C-value (bonded surface area/unbonded surface area) and the volume of the cavity on the volumetric dimensional changes [volumetric setting shrinkage (VSS) and volumetric hygroscopic expansion (VHE)] of a resin-modified glass-ionomer (RMGI) filled in experimental cylindrical cavities were evaluated. The VSS and the VHE rate decreased with increasing C-value. There was a high inverse regression between the cavity C-value and volumetric dimensional changes, but a low regression between cavity volume and volumetric dimensional changes. Therefore, it was thought that greater contraction stress would remain in high C-value cavities than low C-value cavities during the setting process. It was also confirmed that the volumetric dimensional changes of RMGI in cavity were influenced primarily by the cavity C-value.  (+info)

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 ...

A total of 40 extracted human molars were divided into 4 groups (n = 10). The occlusal surfaces were ground flat to expose dentin using diamond discs. Dentin surfaces were treated according to manufacturers instructions, and restorative materials were applied onto a plastic mold of 3mm height and 4mm diameter. The shear bond strength of Ketac Universal and conventional Fuji IX glass ionomer cements was evaluated after 24 h using Instron Universal Testing Machine at a crosshead speed of 0.5 mm/min before and after the specimens were subjected to thrmocycling. 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.

|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 ...

Demineralization during orthodontic (brace) treatment is a common clinical problem leading to unsightly white or brown marks on the teeth. A recent systematic review has shown little evidence that current methods of delivering fluoride are effective at reducing this problem.. Design: A multi-centre randomised single blinded controlled clinical trial will be conducted with two parallel groups.. Setting: The trial patients will be treated by eight named operators on the Specialist List for Orthodontics held by the General Dental Council and who work either within the hospital service or specialist orthodontic practice. The sample size calculation suggests that each operator will need to treat 40 patients in the trial (approx 1 session per week) plus up to 10 familiarisation patients before.. Planned trial interventions: Brackets will be bonded to all teeth in front of the first permanent molars with either a resin-modified glass ionomer cement (Fuji Ortho LC) or a light cured composite control ...

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 ion release profiles and bioactivity of a series of Ti containing glass polyalkenoate cements (GPCs). Characterization revealed each material to be amorphous with a Tg in the region of 650-660ºC. The network connectivity decreased (1.83-1.35) with the addition of TiO2 which was also evident with analysis by X-ray Photoelectron Spectroscopy (XPS). Ion release from cements were determined using Atomic Absorption Spectroscopy (AAS) for zinc (Zn2+), calcium (Ca2+), strontium (Sr2+), Silica (Si4+) and titanium (Ti4+). Ions such as Zn2+ (0.1-2.0 mg/L), Ca2+ (2.0-8.3 mg/L,) Sr2+ (0.1-3.9 mg/L), and Si4+ (14-90 mg/L) were tested over 1-30 days. No Ti4+ release was detected. Simulated body fluid (SBF) revealed a CaP surface layer on each cement while cell culture testing of cement liquid extracts with TW-Z (5 mol% TiO2) produced the highest cell viability (161%) after 30 days. Direct contact testing of discs resulted in a decrease in cell viability of each cement tested ...

Enamel demineralization is a concern in orthodontic patients with poor oral hygiene. To curtail this problem, amorphous calcium phosphate (ACP) containing adhesives have been developed. 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

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 ...
