Comparative Enamel Remineralization Using SDF, Fluoride Varnish, and Curodont™
Objectives: To compare the remineralization efficacy of 5% sodium fluoride varnish (FV), 38% silver diamine fluoride (SDF), and Curodont™ Repair on incipient enamel caries lesions in permanent teeth. Methods: Thirty-two enamel blocks were prepared from eight sound human permanent teeth. Artificial …

Organic matter remineralization in the sediment of two acid mine drainage lakes
… 7.4) to determine the rate of organic matter is remineralization in the sediments of both lakes. Pore water equilibrators were used to obtain concentration depth profiles of ferrous iron (Fe2+), sulfate (SO42-), manganese (Mn2+), and dissolved inorganic carbon (DIC) and to model rates. Results …

Organic matter remineralization in coastal sediments in and around Kane‘ohe Bay, Hawaiʻi
… release of nutrients through organic matter (OM) remineralization during diagenesis. The decomposition and burial of OM in sediments are key processes influencing biogeochemical cycles of nutrients (nitrogen, phosphorus) and carbon in coastal waters on time scales ranging from seasonal …

An investigation of basin-scale controls on upper ocean export and remineralization
… we (1) accurately quantify surface export and remineralization of particulate organic carbon (POC) via the BCP over large regions of the global ocean, (2) examine the factors controlling these POC fluxes and their variability, which includes the cycling of biologically-relevant trace metals, …

The remineralization of marine organic matter by diverse biological and abiotic processes
… scales. The relative strengths of these other remineralization processes — including mechanical mechanisms such as dissolution and disaggregation of sinking particles, and abiotic processes such as photooxidation — remain poorly constrained. In this thesis, I examine the biogeochemical …

Effect of Bottled Water and Fluoride Toothpaste Usage on Caries Lesion Remineralization
… of the tooth structure and enhances remineralization. One of the major public health policies to prevent caries is to provide the population with an adequate amount of fluoride through community water fluoridation. Nowadays many people drink bottled water instead of tap water due to …

A study of the remineralization of organic carbon in nearshore sediments using carbon isotopes
A study of the remineralization of organic carbon was conducted in the organic-rich sediments of Buzzards Bay, MA. Major processes affecting the carbon chemistry in sediments are reflected by changes in the stable carbon isotope ratios of dissolved inorganic carbon (ΣCO2) in sediment pore water. …

The influence of baseline hardness and chemical composition on enamel demineralization and subsequent remineralization
… in demineralized enamel and their influence on remineralization; and 3) To investigate these properties in sound enamel and their influence on remineralization. MATERIALS AND METHODS Incipient subsurface caries lesions were created in 94 bovine enamel specimens using Carbopol C907 using three …

The Effect of Silver Diamine Fluoride on Caries Lesion Remineralization as a Function of Lesion Baseline Mineral Distribution
… in MeC showed significantly greater change (more remineralization) than both SDF (p<0.01) and FV (p=0.01), which were not different from one another (p=0.13). There were no statistically significant differences between SDF and FV in the other lesions (C907 – p=0.18; HEC – p=0.56). For changes in …

Relative fluoride response of caries lesions created in fluorotic and sound teeth studied underremineralizing conditions
… by decreasing demineralization and promoting remineralization of enamel crystals during lesion formation and progression. The chemical, morphological, and histologic characteristics of teeth with fluorosis may alter the response of enamel to fluoride during the caries process. However, the …

Available fluoride ion in solution and one minute fluoride release rate of a toothpaste formulation
… the body’s natural repair process known as remineralization. For remineralization to occur, bioavailable calcium, phosphate, and fluoride ions must be present at the surface of the tooth. Toothpaste products supply bioavailable fluoride ions to the oral cavity. Calcium and phosphate ions are …

Treatment of Enamel Demineralization Following Orthodontic Therapy
… (Ca-P) treatment was developed to enhance remineralization of white spot lesions. We hypothesized that a rinse containing the Ca-P would promote greater remineralization of demineralized enamel in vivo than a fluoride (F)-containing rinse or a placebo rinse. Thirty post-treatment …
