Available fluoride ion in solution and one minute fluoride release rate of a toothpaste formulation
… 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 supplied primarily through the saliva, but in limited quantity. In this research, …

Surface properties and the bioactivity of glass-ionomer dental cements and related materials
… of the surface were noted as well as cation release studies and calcium to phosphorus ratios calculated. The results indicated that a surface layer of calcium phosphate had formed and created a barrier around the cement preventing the loss of strengthening ions. An investigation was also made …

Morphological and Mechanical Properties of Dispersion-Cast and Extruded Nafion Membranes Subjected to Thermal and Chemical Treatments
… degradation had a tremendous effect on the fluoride release rate and chemical degradation kinetics. By exchanging the membranes into the Na+ form, thermal degradation was avoided, allowing us to study the role of crystallinity as a function of fluoride release. Ultimately, Nafion® …

The Development of Assays for Detecting Proximal Phosphorylation and Covalent Modification of Proteins
… warhead, a fluorescent chemosensor-based fluoride-release assay was developed which revealed a diverse range of intrinsic cysteine reactivities. As a proof-of-concept, the electrophilic warhead platform was applied to a clinical covalent tubulin inhibitor for improved potency and …

Bioactive capabilities explored in polyurethane microcapsules and the inclusion into dental sealants and cement pastes
… cement and pit and fissure sealant with fluoride by toothbrushing, demonstrate the slow, sustained release of calcium, fluoride and phosphate ions from these materials initially formulated with remineralizing agents, examine the effect of microcapsules on cement adhesion to enamel and …

Evaluation of Tensile Bond Strength of Glass Ionomer Cements for Orthodontic Bonding
… These include chemical bonding to enamel, fluoride release, and ease of removal from enamel upon debonding. This study evaluated the tensile bond strengths of three Type I (luting) and three Type II (restorative) glass ionomer cements when used to bond a standard stainless steel orthodontic …

Microleakage in new resin-modified glass ionomer cements using new no-rinse conditioners : an in-vitro study
… of glass ionomer cements are chemical bonding, fluoride release and uptake, excellent seal against microleakage, and biocompatibility. The main objective of this study was to compare the microleakage of two new paste-paste glass ionomer systems to their traditional RMGIC counterparts when …

Comparison of Two Orthodontic Sealants in Prevention of Enamel Demineralization : An In-Vitro and In-Vivo Study
… is widely used to provide mechanical coating and fluoride release for the underlying enamel. The purpose of this study was to compare the efficacy in enamel protection during fixed orthodontic treatment in-vitro and in-vivo between two orthodontic sealant products; Opal Seal (Opal Orthodontics by …
