Clinical Evaluation of Glass Ionomer Cement as an Adhesive for the Bonding of Orthodontic Brackets
… has been shown in previous studies to retard decalcification and caries formation. This cement would be valuable in orthodontics if it proved to have adequate adhesive properties. Therefore, this study was designed to determine if there is a significant difference in the failure rate of …

Caracterización del proceso de descalificación en morteros, mediante ensayos destructivos y no destructivos
… waters. Water-based degradation processes cause decalcification of the cementmatrix and can lead to a mechanical failure of the structure, caused by the increase on materials porosity and the loss of mechanical properties. Decalcification process in cement mortars has been characterised in this …

Effectiveness of Resin Infiltration and Mi Paste Cpp-Acp in Masking White Spot Lesions
The development of decalcification around orthodontic brackets and bands, commonly called white spot lesions (WSLs), is often observed in patients with poor oral hygiene during treatment (Behnan et al., 2010, Rodgers et al., 2010). In many instances, these WSLs continue to be visible after the …

The isolation and partial characterization of rat kidney stone matrix induced by magnesium deficiency
… was found to be the mineral component. Decalcification and subsequent dialysis of stones revealed that about 60% of the stone, on a dry weight basis, consists of apatite, and about. 5.8% consists of a nondialyzable organic component termed matrix. A variety of chemical analyses were done …

Patterns of Lithology, Structure, Alteration, Trace Elements, Carbonate Mineralogy, and Stable Isotopes around High-Grade Carlin-type Gold Deposits: Turquoise Ridge Deposit, Getchell District, Nevada
… fault. Visible alteration, consisting of decalcification, argillization, and silicification, strongly correlates with Au grades of >0.34 ppm. Correlation matrices and factor analysis of downhole multi-element data show Au is strongly associated with Hg, As, W, S, Tl, Sb, and Te, but has a …

FRACTURE HEALING IN A RABBIT MODEL: A STUDY OF OSTEOCALCIN LOCALISATION
… bone, used as a source of active bone formation. Decalcification methods were evaluated on 4-week old rabbit bone to enable fracture healing in heavily mineralised adult rabbit bone to be investigated immunocytochemically. In developing rabbit bone osteocalcin was present in osteoblasts and …

Expansive mineral growth and concrete deterioration: a microstructural and microanalytical study
… brucite. Chloride in deicer solutions promotes decalcification of paste. CMA and Mg-acetate produced the most deleterious effects on concrete, with Ca-acetate being much less aggressive. In order to use CMA as an alternative deicer and to prevent premature deterioration, it is recommended that …

Pedogenesis on the Sefton Coastal Dunes, NW England
… leaching of nutrients. Desalinization and decalcification processes lead to brown earth development, followed by increased acidicification, subsequently, resulting in micro-podzol formation. Groundwater gley soils are associated with dune slacks, where drainage is inhibited and anaerobic …

Utilization of crab processing waste and chitin associated with the waste as feed for ruminants
… of quantifying chitin showed that initial decalcification or deprotinization of the samples with chemicals are not necessary. Similar values were obtained for chitin when ADF/ashing method was compared to the ADF/deacetylation method. These methods prevented loss of chitin during …

Genetic and biochemical analysis of materials from a medieval population from Ynys Mon North Wales
… teeth and bones from the site, after extensive decalcification of samples, and also extraction and optimisation trials. Amplification of DNA extracted from teeth samples was generally more successful than for bone samples. A random amplification based polymorphic (RAPD) DNA technique was …

Recognising cryptic alteration surrounding the Mount Isa Copper Deposits: Implications for controls on fluid flow, and mineral exploration
… a distal expression of silicification and decalcification within the core of the mineralising system. The alteration haloes described above, both visible and cryptic, are all contained with the broad zone of ¹⁸O-depletion, representing the most spatially extensive alteration halo to copper …

Development and application of a PCR multiplex to assess the quality and quantity of forensic DNA extracts
… the methods being used. Based on the results, decalcification was not used for any of the extractions as non-decalcified extracts contained higher amounts of DNA. For the phenol-chloroform-isoamyl alcohol extraction it was determined that whilst ethanol precipitation provided higher amounts of …

The Anti-Plaque Efficacy of Listerine® Used in Combination with Toothbrushing in Orthodontic Patients
The bactericidal efficacy of Listerine®, the essential oil-containing mouthrinse, has long been recognized. The purpose of this study was to determine whether Listerine® mouthrinse, when added to the standard oral hygiene regimen, had an added benefit in reducing plaque and gingivitis development …
