Influence of calcium hydroxide on the post-treatment pain in Endodontics: A systematic review.: Even though calcium hydroxide is one of the most widely used int

Calcium hydroxide, traditionally called slaked lime, hydrated lime, slack lime, or pickling lime, is a chemical compound with the chemical formula Ca(OH)2. It is a colourless crystal or white powder, and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It can also be precipitated by mixing an aqueous solution of calcium chloride and an aqueous solution of sodium hydroxide. The name of the natural, mineral form is portlandite. It is a relatively rare mineral, known from some volcanic, plutonic, and metamorphic rocks. It has also been known to arise in burning coal dumps.. When heated to 512 °C, the partial pressure of water in equilibrium with calcium hydroxide reaches 101 kPa and decomposes into calcium oxide and water.[1]. A suspension of fine calcium hydroxide particles in water is called milk of lime. The solution is called lime water and is a medium strength base that reacts violently with acids and attacks many metals in presence of water. It ...

Heres what I got. This one is a bit tricky because, as it turns out, you cant really dissolve enough calcium hydroxide, Ca(OH)_2, in water at room temperature to get a 0.050-M solution. Calcium hydroxide is only sparingly soluble in water; at room temperature, its solubility is equal to 1.73 g L^(-1) at 20^@C. To get its molar solubility at this temperature, use its molar mass 1.73 color(red)(cancel(color(black)(g)))/L * (1 mole Ca(OH)_2)/(74.1 color(red)(cancel(color(black)(g)))) = 0.02335 mol L^(-1) This means that you can only hope to dissolve 0.02335 moles of calcium hydroxide per liter of water before the solution becomes saturated. Any additional calcium hydroxide added to the solution will remain undissolved. Now, calcium hydroxide is considered a strong base, which means that the amount of calcium hydroxide that does dissolve in water dissociates completely to form calcium cations, Ca^(2+), and hydroxide anions, OH^(-). Ca(OH)_ (color(red)(2)(aq)) -| Ca_ ((aq))^

This paper analyses the efficacy of dispersions of nanoparticles of calcium hydroxide for consolidating lime mortars, according to three variables: the type of dispersion (three consolidating compounds-CaLoSil®, Nanorestore® and Merck®-with different-sized calcium hydroxide particles); the concentration of the dispersion (5 and 25 g/L of Ca(OH)2 in isopropyl alcohol); and the state of the sample (comparison of saturated and non-saturated samples). The outcome of the consolidation process was studied in terms of improved carbonation of the mortar, mineralogy (by means of X-ray diffraction and thermogravimetric analyses), texture (study of the porosity by mercury intrusion porosimetry) and compactness (measurement of ultrasonic velocity propagation through samples). To ensure that the treatment had no negative effects on the physical characteristics of the mortars, we performed microstructural (phase morphology studied by means of scanning electron microscopy) and aesthetic (colour and ...

The next topic to be discussed is another modification which is in the mixing liquid. The first generation materials were supplied in sessions, which had the powder, which was made up of the cement and the radiopacifier, and a mixing liquid. The mixing liquid is usually water. With the second generation materials, the mixing liquid has been modified. In the premixed, there is no mixing liquid. Such materials are supplied in syringes, such as sealers and pastes, and they have no mixing liquid. They are applied in the canal. Anywhere there is like the root-end, or perforation repair, and they rely on the moisture, or blood that is present inside the area where they are placed for hydration to work here. This can be slightly problematic because if the area has been dried and there is not enough liquid, there is a risk that the material will not hydrate. And if the material will not hydrate, there will be no calcium hydroxide formed. If no calcium hydroxide is formed, the material properties will ...

One potential contributor to higher CO2 levels that we have not considered previously is the inhalation of CO2 during use of a rebreather. Normally the gas we respire (for example, the air around us) contains only a tiny and inconsequential amount of CO2. But during use of a rebreather, because the exhaled breath is recycled, there is the possibility of re-inhaling our own expired CO2. If CO2 is actually inhaled, then its elimination from the body is reduced; potentially markedly so.. Rebreather divers rely on a canister of CO2 scrubber material to remove the CO2 from the exhaled breath before it is re-inhaled. This canister contains a compound material called soda-lime which comes as a preparation of tiny hard granules 1-2mm in size. Through a series of chemical reactions, exhaled CO2 is combined with calcium hydroxide to produce calcium carbonate. Because this reaction is uni-directional, the absorptive capacity of a given amount of soda-lime is finite. Most rebreathers contain enough ...

Supa Chlor and probably the most sophisticated water conditioner in the world, it is the only product that is manufactured to recognize one of the primary problems associated with town water. That is hydrated lime, lime is used to buffer the pH of town water world wide, and is one of the least understood toxins in the Aquarium. Lime can be linked to a whole range of diseases, primarily fungal infections, the most common ailment to effect ornamental fish. This toxin is removed by chelation of the Calcium molecule which allows the hydroxide ion to become water by being attracted to hydrogen in water (Lime =Calcium Hydroxide converts to Sodium) This conversion is done with a bound phosphate, which is then left over to be used as plant fertilizer, this phosphate will not adversely effect aquarium water and is a benefit to plants and fish.EDTA is the most commonly used remover of toxic metals in normal Aquarium Water Conditioners but is exhausted because it is only moderately effective with Lime. ...

Background: Restorations have been known to have a detrimental effect on the periodontium with certain teeth or groups of teeth prone to develop more severe periodontal destruction. This study compared the periodontal health of restored molars with that of unrestored molars and determined the correlation between the type, age, and status of the restorations on the molars and the health of the associated periodontium. Materials and Methods: Patients with at least one restored molar and its contralateral counterpart of one unrestored molar were recruited for the study. The type of restoration and material, age of restoration, and type of defects on the restoration were noted in the restored group, while the degree of tooth mobility, furcation involvement, gingival recession, gingival status, and periodontal pockets depth were measured in all teeth studied.

Ive been carbon dosing since day 1 because I cycled with the Red Sea program, but instead of paying out for NoPox I switched to vinegar in my Kalkwasser top-off. This worked great, my nitrates and phosphates were exactly where I wanted them. But my pH was getting worryingly low. The vinegar at 45mL per gallon was overpowering the high pH of the Kalk. So I mixed a new batch of Kalk with half the dosage of vinegar, and now my pH is looking a lot better... BUT now my skimmer is basically spinning around doing nothing. I lowered the carbon too much it seems. Im going to be keeping a close eye on my Nitrates this week, but Im trying to plan ahead for how to add more carbon if that becomes necessary. Has anyone used vodka with vinegar in Kalk? Vinegar is the go-to carbon source for Kalkwasser because it helps to bind more calcium hydroxide in the RO/DI water, and it is cheap. Ive been unable to find any mention of someone using a combination of the two. The only thing I can find is general rules ...

The goals of nonvital pulp treatment are to prevent the premature loss of primary teeth, and maintain primary teeth functions . The success rates of pulpectomy in primary teeth have been reported from 75% to 96% depends on type of root canal materials . Root canal anatomy in primary molars is quite varied and complex causing difficulty for cleaning and shaping canals while the complexity of root canal anatomy may also affect the success rate of root canal treatment . Pulpectomy in primary teeth is usually treated completely within one visit; however, two-visit pulpectomy is necessary when the root canal has remaining exudate or the tooth has acute infection. For these conditions, intracanal medication is needed to be places in root canals between visits. This helps to clear up of residual bacteria and preventing re-infection in the root canal systems .. Intracanal medicaments, which are commonly used in endodontic treatment, are volatile medicament (phenolic compound and aldehyde groups), ...

Note what the question actually asks you, roughly. Approximation is an important tool in ionic equilibrium calculations.. Here, you have $0.0126M \text{ }\ce{Ca}^{+2}$ and $0.0252M\text{ } \ce{OH-}$ in the original solution. By addition of $0.1M \text{ }\ce{NaOH}$, which is a strong electrolyte, youll not only add $0.1M\text{ } \ce{OH-}$ to the solution, but also cause $Q$ to exceed $K_{sp}$, hence, the salt will be precipitated out.. Now, the concentration of our ions before precipitation is $0.0126M \text{ }\ce{Ca}^{+2}$ and $0.1252M\text{ } \ce{OH-}$. Let $y$ be the fraction of existing ions that are not precipated out. So, well be left with $0.0126 \cdot y M \text{ }\ce{Ca}^{+2}$ and $0.1252 \cdot (2y-1) M\text{ } \ce{OH-}$ ions. Equating their ionic product to the salts $K_{sp}$, we get:. $$0.0126 \cdot y\cdot(0.1252\cdot (2y-1))^2=8\times10^{-6}$$. $$y\cdot(2y-1)^2\approx0.0405$$ $$y\cdot(1+4y^2-4y)\approx0.0405$$.

My lab group and I are a bit confused. We are doing a lab where we need to calculate the Ksp of calcium hydroxide in pure water and then in different concentrations of calcium chloride and potassium chloride to analyze the diverse and common ion effect. I was absent one day but my lab partner told me that the teacher said Ksp for calcium hydroxide will remain constant for the solutions of potassium chloride and calcium chloride. She wants us to make a graph where we compare the molar solubilities of the different solutions, not the Ksp. My question is how on earth can something that tells us about solubility, Ksp, remain constant when more is forced to dissolve, KCl, and less is forced to dissolve, CaCl2????? Does this mean the molar solubility calculation is really as easy as just determining the calcium ion concentration in each solution and dividing it by the total volume? Gracias ...

a) Firstly 5 kg of calcium oxide are introduced into a plastic tub and made into a slurry with 20 kg of purified water. The formation of calcium hydroxide (quicklime) which takes place under these conditions leads to a large rise in temperature of the solution. The calcium hydroxide can therefore be used further only after cooling. The temperature of the solution is then 30° C. to 35° C.b) 50 kg of drug are introduced into a mixer, and the abovementioned quicklime is added. In order to remove the quicklime as completely as possible from the plastic tub, it is rinsed with 10 kg of purified water. This washing liquid is likewise put in the mixer.c) The drug homogeneously mixed with quicklime is introduced into a percolator and covered with 160 kg of purified water. The percolator remains closed for 48 hours. The percolate is then collected in a suitable vessel at a flow rate of 50 ml/min. The percolation is continued until no further percolate emerges.

This paper proposes a simple model for predicting the development of deleterious expansion from alkali-silica reaction (ASR) in long-service concrete structures. This model is based on some composition and reactivity parameters related to ASR, including the long-term alkali contribution by aggregates to concrete structures. This alkali contribution was estimated by means of a laboratory extraction test, appositely developed in this study in order to maximize the alkali extraction within relatively short testing times and with low leaching solution/aggregate ratios. The proposed test is a modification of the Italian Standard test method UNI 11417-2 (Ente Nazionale Italiano di Normazione) and it consists of subjecting an aggregate sample to leaching with saturated calcium hydroxide solution in a laboratory autoclave at 105 °C. Nine natural ASR-susceptible aggregates (seven sands and two coarse aggregates) were tested and the following optimized test conditions were found: leaching solution/aggregate

In the last years HA has been explored in a new area of application where it, in the form of nanoparticles (NPs), has been used as a carrier for the delivery of drugs and genes inside targeted cells. In spite of the promising results, which have been reported up to day, there are fundamental questions that remain unanswered. The goal of this project is to address one specific aspect: if the addition of doping ions in the formulation of hydroxyapatite NPs affects cell behaviour. For this purpose the first objective was to prepare HA NPs with various types and degree of ion substitution: carbonate (CO3)-, magnesium (Mg)- and CO3-Mg-co-substituted HA NPs. They were prepared via a wet precipitation route involving neutralization of calcium hydroxide with phosphoric acid and were characterised by X-ray diffraction ...

Any chance these speaker cones have a metallic colorant? I used to mold some speaker cones that were colored metallic silver. No matter what we did to the process we experienced intermittent dark lines that looked like flowlines in the direction of flow. The color supplier told me that these lines happen because the metal flakes line up sideways and look dark - and that there was nothing that could be done about it. Without seeing the flowlines you are describing, that is the best guess I can give ...

Filtration Options - Ive got an extra R.O. filter setup (3-10 in. canisters + R.O. membrane). I was wondering whether I could use the three canister filters (i.e., bypass the R.O. membrane) and place them in the main pump return flow line in order to occasionally take advantage of micron-level filtration? Thanks. ,I would not do this unless you have an unlimited budget for replacing the filters. Youll find that placing them in the main return path will reduce your flow rate and clog the filters very quickly. Cheers, J -- ,. Kati/Ani de-ionizer 1/25/05 Im very interested in these units since theyve been highly recommended and Im not a fan of wasting water with RO.

So on to the experts (I hope Im not wasting your time). ,no worries, First ...
