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)

Resin cements are dental materials that are used to bond dental restorations, such as fillings, crowns, and bridges, to the tooth structure. They are made from a combination of resin monomers, polymers, and other ingredients that are cured with light or heat to form a strong, durable bond. Resin cements are preferred over traditional dental cements because they have a number of advantages, including: 1. Improved adhesion: Resin cements bond to both tooth structure and dental restorations, providing a stronger and more durable bond than traditional cements. 2. Better esthetics: Resin cements can be matched to the color of the tooth, providing a more natural-looking restoration. 3. Increased strength: Resin cements are stronger than traditional cements, which can reduce the risk of fractures and other types of damage to the tooth. 4. Faster curing: Resin cements can be cured in just a few seconds, which can reduce the time required for dental procedures. Overall, resin cements are a popular choice for dental restorations because of their improved adhesion, esthetics, strength, and curing time.

In the medical field, aluminum silicates are a type of mineral compound that is commonly used as an antacid and an adsorbent. They work by neutralizing stomach acid and binding to toxins and other substances in the digestive tract, which helps to prevent their absorption into the bloodstream. Aluminum silicates are often used to treat conditions such as heartburn, acid reflux, and indigestion. They are available in a variety of forms, including tablets, capsules, and powders, and can be taken orally or used topically. It is important to note that while aluminum silicates are generally considered safe for short-term use, long-term use or high doses may have potential side effects, such as constipation, nausea, and abdominal pain. As with any medication, it is important to follow the instructions of your healthcare provider and to report any adverse reactions.

Dental cements are materials used in dentistry to bond dental restorations, such as fillings, crowns, and bridges, to the teeth. They are also used to bond dental implants to the jawbone. Dental cements are typically composed of a powder and a liquid, which are mixed together to form a paste that can be applied to the tooth or implant surface. The paste then hardens, forming a strong bond between the restoration and the tooth or implant. There are several different types of dental cements, each with its own unique properties and intended use. Some common types of dental cements include zinc phosphate cement, glass ionomer cement, and resin cement.

In the medical field, "Resins, Synthetic" refers to a group of synthetic polymers that are derived from petrochemicals or other organic compounds. These resins are used in a variety of medical applications, including as adhesives, coatings, and as components in medical devices. Some examples of synthetic resins used in the medical field include polyvinyl chloride (PVC), polyethylene terephthalate (PET), and polystyrene. These resins are often used to make medical devices such as catheters, tubing, and containers for medical supplies. Synthetic resins are also used in medical coatings to provide a barrier against bacteria and other microorganisms, as well as to improve the durability and performance of medical devices. For example, some medical implants are coated with synthetic resins to reduce the risk of infection and to improve their biocompatibility with the body. Overall, synthetic resins play an important role in the medical field by providing a range of useful properties and applications in the development and production of medical devices and supplies.

Dental bonding is a cosmetic dental procedure that involves applying a tooth-colored resin material to a tooth surface to improve its appearance. The resin is then hardened with a special light, creating a strong and natural-looking bond with the tooth. Dental bonding can be used to repair chips, cracks, gaps, and stains on teeth, as well as to close spaces between teeth and to improve the shape and size of teeth. It is a quick and relatively painless procedure that can be completed in a single visit to the dentist.

Acrylic resins are a type of polymer that are commonly used in the medical field for a variety of applications. They are typically made from acrylic acid or methacrylic acid, which are then polymerized to form a solid, durable material. One common use of acrylic resins in medicine is in the production of dental prosthetics, such as dentures and dental bridges. Acrylic resins are used to create the artificial teeth and gums that are used to replace missing teeth or to improve the appearance of the smile. Acrylic resins are also used in the production of medical devices, such as catheters and surgical instruments. They are often used because of their durability, flexibility, and ability to be molded into a variety of shapes and sizes. In addition, acrylic resins are sometimes used in the treatment of certain medical conditions. For example, they may be used to create implants for the treatment of joint disorders or to reinforce weakened bones. Overall, acrylic resins are a versatile and widely used material in the medical field, with a range of applications in dentistry, medical devices, and other areas.

Magnesium oxide is a white, odorless powder that is commonly used in the medical field as a dietary supplement and as an antacid. It is also used in some medications to treat certain digestive disorders, such as heartburn and acid reflux. In the body, magnesium oxide is used to help regulate muscle and nerve function, and to support healthy bone density. It is also thought to have a calming effect on the nervous system and may help to reduce anxiety and stress. Magnesium oxide is available over-the-counter at most drugstores and health food stores. It is usually taken by mouth in the form of a tablet or powder. It is important to follow the recommended dosage instructions on the label or as directed by a healthcare provider.

Dental cavity preparation is a dental procedure that involves removing decayed or damaged tooth structure from a tooth in order to create a smooth, clean surface for a filling or other restoration. This procedure is typically performed by a dentist or dental hygienist using specialized dental tools, such as dental drills and hand instruments. During a dental cavity preparation, the dentist will first numb the affected area of the tooth using a local anesthetic. They will then use a dental drill to remove the decayed or damaged tooth structure, carefully shaping the cavity to create a smooth, clean surface. The dentist may also use hand instruments to further refine the shape of the cavity and remove any remaining decay. Once the cavity has been prepared, the dentist will fill it with a dental filling or other restoration, such as a crown or a dental bridge. The restoration will be shaped to match the natural contours of the tooth and will be bonded in place using a special dental cement. Dental cavity preparation is an important procedure for maintaining good oral health and preventing further tooth decay.

It is also used in the production of orthopedic implants, such as hip and knee replacements, as well as in the fabrication of prosthetic devices. Additionally, zirconium is used in the production of certain types of medical equipment, such as MRI machines, due to its low magnetic susceptibility.

Aluminum oxide is a chemical compound that is commonly used in the medical field as a desiccant, an agent that removes moisture from a substance. It is also used as a polishing agent for dental work and as a component in some types of dental fillings. In addition, aluminum oxide is used in the production of certain types of medical equipment, such as surgical instruments and implants. It is generally considered to be safe for medical use, but it can cause irritation or allergic reactions in some people.

Calcium phosphates are a group of minerals that are commonly found in the human body, particularly in bones and teeth. They are also used in medical applications, such as in the production of bone grafts and dental implants. Calcium phosphates are composed of calcium and phosphorus ions, and they are typically crystalline in structure. There are several different types of calcium phosphates, including hydroxyapatite, octacalcium phosphate, and brushite. In the medical field, calcium phosphates are often used as a source of calcium and phosphorus for patients who are unable to obtain these nutrients from their diet. They are also used in the treatment of bone diseases, such as osteoporosis, and in the repair of bone fractures. In addition, calcium phosphates are used in the production of medical devices, such as dental implants and bone grafts, because of their biocompatibility and ability to support bone growth.

Dental amalgam is a type of dental filling material that is commonly used to restore teeth that have been damaged by decay or injury. It is made up of a mixture of metals, including silver, tin, copper, and mercury, which are combined to form a hard, durable material that can be shaped to fit the contours of a tooth. Dental amalgam has been used for over 150 years and is still widely used today because it is effective, durable, and relatively inexpensive. It is also a safe and effective treatment option for most patients, as the amount of mercury used in dental amalgam is very small and is not considered to be a health risk. However, some people may be concerned about the use of mercury in dental amalgam and may choose to have alternative filling materials, such as composite resin or glass ionomer cement, instead. It is important to discuss the pros and cons of different filling materials with your dentist to determine the best option for your individual needs.

Polyurethanes are a class of polymers that are widely used in the medical field due to their unique properties, such as their flexibility, durability, and biocompatibility. They are typically used to make a variety of medical devices, including catheters, implants, and prosthetics. In the medical field, polyurethanes are often used to create materials that can mimic the properties of natural tissues, such as skin, cartilage, and bone. They can also be used to create materials that are more durable and resistant to wear and tear than natural tissues. Polyurethanes can be synthesized from a variety of starting materials, including diisocyanates, polyols, and catalysts. The properties of the resulting polyurethane can be tailored by adjusting the composition of the starting materials and the reaction conditions. Overall, polyurethanes are a versatile and useful material in the medical field, with a wide range of potential applications in the development of new medical devices and treatments.

Air abrasion, dental, is a minimally invasive dental procedure that uses a high-speed stream of abrasive particles to remove tooth decay or other dental damage. The particles are directed at the tooth surface using a hand-held device, and the pressure of the air stream helps to control the depth and precision of the removal. Air abrasion is often used as an alternative to traditional drilling, which can be more invasive and cause more discomfort for patients. It is a quick and painless procedure that can be used to treat a variety of dental problems, including cavities, tooth wear, and minor chips or cracks.
