Study of resin-bonded calcia investment: Part 1. Setting time and compressive strength. (1/25)
This study was carried out to develop a new titanium casting investment consisting of calcia as the refractory material and a cold-curing resin system as the binder. The setting time of the investment was investigated under different N,N-dimethyl-p-toluidine (DMPT) contents in methyl methacrylate monomer (MMA) and benzoyl peroxide (BPO) contents in calcia without any sintering agent. The effects of the sintering agents, which were calcium fluoride (CaF2) and calcium chloride (CaCl2), on the compressive strength of the investments were investigated at room temperature before and after heating to two different temperatures. The shortest setting time (68 minutes) of the investment was obtained at 0.37 DMPT/BPO (1.5 vol% /1.0 mass%) ratio by mass. The highest strength (16.5 MPa) was obtained from the investment which contained 2 mass% CaF2 and was heated to 1,100 degrees C. It was found that the developed calcia investment containing 2 mass% CaF2 has a possibility for use in titanium castings. (+info)Study of resin-bonded calcia investment: part 2. Effect of titanium content on the dimensional change of the investment. (2/25)
In the present study, titanium powder was chosen as an expanding agent of an experimentally prepared resin-bonded calcia investment. The effect of Ti content on the dimensional change was investigated. In addition, the effects of the heating rate and heating temperature on the dimensional change of the investment were investigated during setting and after heating. The expansion increased with Ti content and the highest expansion (1.57%+/-0.58) was obtained at 10 mass% Ti. The highest expansion was obtained at 900 degrees C for 30 min heating and was independent of the heating rate. These findings mean that the titanium powder in the calcia investment oxidized sufficiently at that heating condition. It was found that the developed resin-bonded calcia investment was able to compensate for casting shrinkage of pure titanium by adding some Ti powder to the investment. (+info)Binding of cations of group IA and IIA to bovine serum amine oxidase: effect on the activity. (3/25)
In this paper, we report on the presence of cation binding areas on bovine serum amine oxidase, where metal ions of the groups IA and IIA, such as Na(+), K(+), Cs(+), Mg(2+), and Ca(2+), bind with various affinities. We found a cation-binding area that influences the enzyme activity if occupied, so that the catalytic reaction may be altered by some physiologically relevant cations, such as Ca(2+) and K(+). This binding area appears to be localized inside the enzyme active site, because some of these cations act as competitive inhibitors when highly charged amines, such as spermine and spermidine, are used as substrates. In particular, dissociation constant values (K(d)) of 23 and 27 mM were measured for Cs(+) and Ca(2+), respectively, using, as substrate, spermine, a polyamine of plasma. An additional cation-binding area, where metal ions such as Cs(+) (K(d) congruent with 0.1 mM) and Na(+) (K(d) congruent with 54 mM) bind without affecting the enzyme activity, was found by NMR. (+info)Thermoluminescence in sintered CaF2:Tb. (4/25)
In order to observe and estimate the dose of ultraviolet (UV) radiation, the thermoluminescence (TL) of sintered CaF2 doped with Tb4O7 and Sm2O3 was studied. A several kind of lanthanides elements are doped in pure CaF2 powder crystals and properties of the TL to UV radiation were observed. The TL intensity from CaF2:Tb was the highest among the samples doped other lanthanide elements. The TL emission may be due to the recombination reaction; Tb2+ + hole-->Tb3+*-->Tb3+ + hv. The TL peaks are observed at about 353 K, 378 K and 458 K. It was found that the 378 K TL peak intensity of CaF2:Tb became strong by addition of Sm2O3. The 378 K TL peak may also be suitable for use as a dosimeter. (+info)Preparation and properties of nano-sized calcium fluoride for dental applications. (5/25)
OBJECTIVES: The aim of the present study was to prepare nano-sized calcium fluoride (CaF(2)) that could be used as a labile F reservoir for more effective F regimens and as an agent for use in the reduction of dentin permeability. METHODS: Nano-sized CaF(2) powders were prepared using a spray-drying system with a two-liquid nozzle. The properties of the nano-CaF(2) were studied and the effectiveness of a fluoride (F) rinse with nano-CaF(2) as the F source was evaluated. The thermodynamic solubility product of the nano-CaF(2) solution was determined by equilibrating the nanosample in solutions presaturated with respect to macro-CaF(2). Reactivity of the nano-CaF(2) was assessed by its reaction with dicalcium phosphate dehydrate (DCPD). F deposition by 13.2 mmol/L F rinse with the nano-CaF(2) as the F source was determined using a previously published in vitro model. RESULTS: X-ray diffraction (XRD) analysis showed pattern of low crystalline CaF(2). BET measurements showed that the nano-CaF(2) had a surface area of 46.3m(2)/g, corresponding to a particle size of 41nm. Transmission electron microscopy (TEM) examinations indicated that the nano-CaF(2) contained clusters comprising particles of (10-15) nm in size. The nano-CaF(2) displayed much higher solubility and reactivity than its macro-counterpart. The CaF(2) ion activity product (IAP) of the solution in equilibrium with the nano-CaF(2) was (1.52+/-0.05)x10(-10), which was nearly four times greater than the K(sp) (3.9 x 10(-11)) for CaF(2). The reaction of DCPD with nano-CaF(2) resulted in more F-containing apatitic materials compared to the reaction with macro-CaF(2). The F deposition by the nano-CaF(2) rinse was (2.2+/-0.3)mug/cm(2) (n=5), which was significantly (p<0.001) greater than that ((0.31+/-0.06)mug/cm(2)) produced by the NaF solution. SIGNIFICANCE: The nano-CaF(2) can be used as an effective anticaries agent in increasing the labile F concentration in oral fluid and thus enhance the tooth remineralization. It can also be very useful in the treatment for the reduction of dentin permeability. (+info)TiF(4) varnish-A (19)F-NMR stability study and enamel reactivity evaluation. (6/25)
The aim of this study was to develop a titanium tetrafluoride (TiF(4)) varnish and evaluate the stability of the formulation and its reactivity with dental enamel. The varnish was prepared in a resinous matrix using ethanol 96% as solvent. Samples (n=45) were aged at 65 degrees C and 30% of relativity humidity (RE n degrees 01/05-ANVISA) and after 3, 6, 9 and 12 months, nine samples were removed for evaluation and compared with fresh samples. Chemical stability of TiF(4) varnish was determinate by (19)F-NMR and the reactivity of the formulation was quantified by formation of fluoride loosely (CaF(2)) and firmly bound (fluorapatite; FA) to enamel. For reactivity comparisons, a varnish without TiF(4) was used as control. The loss of soluble fluoride was about 0.9% after one year of storage. The values of the reactivity (mean+/-S.D.) of fresh, aged at 3, 6, 9 and 12 months and control samples were: CaF(2) (microg F/mm(2)): 89.3+/-27.5(a); 54.5+/-14.3(b); 51.2+/-29.8(b); 69.3+/-21.3(a); 48.0+/-27.4(b); 0.10+/-0.07(c), FA (microg F/g): 2477.5+/-1044.0(a); 2484.8+/-992.0(a); 2580.0+/-1383.9(a); 2517.2+/-929.9(a); 2121.0+/-1059.2(a); 330.0+/-180.0(b), respectively. Means followed by distinct letters were statistically different (p<0.05). After one year of storage, the formulation was chemically stable and the levels of FA were maintained. However there was an initial decrease in the ability to form CaF(2). (+info)Effect of a bonding agent on in vitro biochemical activities of remineralizing resin-based calcium phosphate cements.

(+info)Calcium fluoride is a mineral that is sometimes used in dental products to help prevent tooth decay.
Calcium fluoride is a chemical compound that is commonly used in the medical field as a fluoride supplement. It is a white, crystalline solid that is highly soluble in water and is commonly used as a fluoride source in toothpaste, mouthwashes, and other dental products. In the medical field, calcium fluoride is used to help prevent tooth decay by increasing the concentration of fluoride in the mouth. Fluoride helps to strengthen tooth enamel and make it more resistant to acid attacks from bacteria in the mouth. It is also used to treat certain types of dental fluorosis, which is a condition that occurs when there is an excess of fluoride in the body. Calcium fluoride is generally considered safe when used as directed, but it can cause side effects such as nausea, vomiting, and diarrhea if taken in large amounts. It is important to follow the recommended dosage and to speak with a healthcare provider before using calcium fluoride or any other fluoride supplement.
Fluorides are compounds that contain the fluoride ion and are used in the medical field for the prevention and treatment of dental caries (cavities).
Fluorides are compounds that contain the fluoride ion (F-). In the medical field, fluorides are commonly used to prevent tooth decay and improve oral health. They can be found in a variety of products, including toothpaste, mouthwashes, and fluoride supplements. Fluoride works by strengthening tooth enamel, making it more resistant to acid attacks from bacteria in the mouth. It can also help to remineralize tooth enamel that has already been damaged by acid. Fluoride is also used in water treatment to reduce the risk of tooth decay in communities. In addition, fluoride is sometimes used in dental procedures, such as fluoride varnishes and fluoride gels, to further strengthen teeth and prevent decay. While fluoride is generally considered safe and effective, excessive exposure to fluoride can lead to dental fluorosis, a condition that causes white or brown stains on the teeth. It is important to use fluoride products in moderation and to follow the instructions on the label.
Cariostatic agents are substances used to prevent tooth decay by inhibiting the growth of bacteria that cause cavities.
Cariostatic agents are substances that help prevent tooth decay (caries) by inhibiting the growth of bacteria that cause cavities. These agents work by either killing the bacteria or preventing them from adhering to the tooth surface, thereby reducing the formation of plaque and tartar. Some common cariostatic agents used in the medical field include fluoride, chlorhexidine, and triclosan. Fluoride is the most widely used cariostatic agent and is found in many toothpastes, mouthwashes, and drinking water. Chlorhexidine is a mouthwash that is often used in hospitals and dental offices to prevent the spread of infection. Triclosan is an antibacterial agent that is found in some toothpastes and mouthwashes. Cariostatic agents are an important part of dental care and can help prevent tooth decay and maintain good oral health. However, it is important to note that they should not be used as a substitute for regular brushing and flossing, and that a healthy diet and regular dental check-ups are also important for maintaining good oral health.
Sodium fluoride is a dental fluoride treatment used to prevent tooth decay by strengthening tooth enamel.
Sodium fluoride is a chemical compound that is commonly used in the medical field as a fluoride supplement to prevent tooth decay. It is also used in dental products such as toothpaste and mouthwash to help strengthen tooth enamel and prevent cavities. In the medical field, sodium fluoride is typically administered as a solution or tablet to patients who are at risk of developing tooth decay. It is also used in certain medical treatments, such as radiation therapy, to help prevent the development of new blood vessels in tumors. Sodium fluoride is generally considered safe when used as directed, but high doses or prolonged exposure can be harmful. It is important to follow the recommended dosage and use caution when administering sodium fluoride to patients, especially children.
Topical fluorides are agents that are applied to the teeth to prevent and treat dental caries (cavities) by increasing the fluoride concentration in the enamel and reducing demineralization.
Fluorides, topical, refer to a class of medicaments that contain fluoride ions and are applied topically to the teeth and oral mucosa to prevent dental caries (cavities) and to remineralize tooth enamel that has already been demineralized. Topical fluorides are available in various forms, including gels, foams, rinses, toothpastes, and mouthwashes. They are typically used as an adjunct to other oral hygiene practices, such as brushing and flossing, to help maintain good oral health. The fluoride ions in these medicaments can penetrate the enamel and dentin of the teeth, making them more resistant to acid attacks from bacteria in the mouth.
Gasoline is a flammable liquid used as a fuel in internal combustion engines, and has no direct relevance to the medical field.
In the medical field, gasoline is not typically used as a medical treatment or diagnostic tool. Gasoline is a flammable liquid that is primarily used as a fuel for internal combustion engines, such as those found in cars, trucks, and other vehicles. However, gasoline can be a dangerous substance if it is ingested or inhaled in large quantities. Ingesting gasoline can cause nausea, vomiting, abdominal pain, and even death. Inhaling gasoline fumes can cause dizziness, headaches, and respiratory problems, and can also be fatal if exposure is prolonged or severe. If someone has ingested or inhaled gasoline, it is important to seek medical attention immediately. Treatment may involve removing the gasoline from the body, providing supportive care to manage symptoms, and addressing any long-term health effects.
Antimony is a toxic heavy metal that has been used in some medicinal treatments, particularly for the parasitic infection schistosomiasis, but its use is now limited due to toxicity and the availability of safer alternatives.
Antimony is a chemical element that has been used in the medical field for various purposes. In medicine, antimony is used as an antiparasitic agent to treat infections caused by parasites such as leishmaniasis, schistosomiasis, and trypanosomiasis. It is also used in the treatment of certain types of cancer, such as acute promyelocytic leukemia. Antimony compounds are available in various forms, including intravenous solutions, tablets, and topical creams. The most commonly used antimony compound in medicine is sodium stibogluconate, which is administered intravenously to treat leishmaniasis. Antimony can cause side effects, including nausea, vomiting, abdominal pain, and allergic reactions. It can also be toxic in high doses, so it is important to use it under the supervision of a healthcare professional.
Crops, agricultural refers to the cultivation and harvesting of crops for food, feed, and other agricultural products.
In the medical field, "Crops, Agricultural" typically refers to the cultivation and harvesting of crops for food, fiber, or other agricultural products. This can include a wide range of crops, such as grains, fruits, vegetables, and livestock feed. The medical field may be interested in agricultural crops for several reasons. For example, some crops may be used as sources of dietary fiber or other nutrients that can help prevent certain diseases. Others may be used to produce biofuels or other industrial products. Additionally, the use of pesticides and other chemicals in agriculture can have potential health effects on both humans and the environment, so the medical field may study the impact of these practices on human health. Overall, the medical field may be interested in agricultural crops as a way to understand the impact of food production on human health and the environment, and to develop strategies for promoting sustainable and healthy food systems.
Volatile Organic Compounds (VOCs) are organic chemicals that have a high vapor pressure at room temperature and can be released into the air from various sources, including medical devices and cleaning products.
In the medical field, Volatile Organic Compounds (VOCs) are organic chemicals that have a high vapor pressure at room temperature, which means they can easily evaporate and become airborne. VOCs are commonly found in various indoor environments, including homes, offices, and hospitals, and can have negative health effects on humans. Some common VOCs found in indoor environments include formaldehyde, benzene, toluene, and xylene. These chemicals can be emitted from various sources, such as building materials, cleaning products, and personal care products. Exposure to high levels of VOCs can cause a range of health problems, including headaches, dizziness, nausea, and respiratory issues. In some cases, long-term exposure to VOCs has been linked to more serious health problems, such as cancer. Therefore, it is important to monitor and control the levels of VOCs in indoor environments to protect human health. This can be done through proper ventilation, the use of low-VOC products, and regular air quality testing.
Nitrites are compounds that can be used as medications to treat certain medical conditions, such as angina, and as food additives to preserve color and flavor.
In the medical field, nitrites are compounds that contain the nitrite ion (NO2-). Nitrites are often used as a medication to treat certain types of heart disease, such as angina pectoris, by relaxing the blood vessels and reducing the workload on the heart. They are also used to treat certain types of anemia, such as methemoglobinemia, by converting methemoglobin (a form of hemoglobin that is unable to carry oxygen) back to normal hemoglobin. Nitrites are also used as a preservative in some foods and beverages, and as a chemical in the manufacturing of dyes, explosives, and other products.
