Zinc-fluoride glass nanoparticles (Zinc-F) release several ions, such as fluoride, zinc and calcium through acid-base reactions. The aim of this study was to evaluate the antibacterial cytotoxic properties Zinc-F. Antibacterial tests showed that a Zinc-F eluting solution significantly reduced turbidity colony-forming units Streptococcus mutans Actinomyces naeslundii, compared calcium-fluoroalum...

PURPOSE The objectives of this study were to investigate the fluoride levels in plaque and saliva before and after applying fluoride-containing pit and fissure sealants, and compare the fluoride release of 2 types of sealants at the different time intervals. METHODS Eighteen children ages 6 to 9 years were randomly divided into 2 groups: Group 1--sealant containing fluorosilicate glass (Helio...

OBJECTIVE The aim of this study was to evaluate the antimicrobial and fluoride releasing capacity of 3 bonding materials. MATERIAL AND METHODS Thirty nine specimens with standardized surface smoothness and dimensions were prepared. The antimicrobial capacity of the materials against S. mutans, L. casei and C. albicans was evaluated by determining the percentage of growth inhibition of these m...

The bioactive glasses have been used in the medical field due to their wide spread benefits as implant coatings, bone substitutes and for treatment of dentine sensitivity. The purpose of this study was to incorporate zinc and fluoride in the bioactive glass for potential use in dentifrices as antibacterial and anticaries agents. A series of glass compositions based on SiO2, CaO, CaF2, MgO, and ...

AIM To synthesise fluoridated hydroxyapatite (FA) crystals directly on preformed metal crowns (PMCs) and evaluate the anti-cariogenic properties in an in vitro model. METHODS FA crystals were grown on etched PMCs and stainless steel discs and characterised by SEM. FA-coated discs allowed fluoride release to be assessed from a known surface area of FA crystals. Discs were divided into four gro...

The clearance pattern of a specific substance is very important to estimate its oral availability. Devices or models that simulate clearance in the mouth are important to study the effects and retention time of foods and drugs. This report describes an efficient device which was assembled with low-cost materials in our laboratory and that can be used to study the clearance of cariogenic substra...

We evaluated the concentration of fluoride release at the initial stage and after recharging the fluoride from a resin-based sealant containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler and conventional resin-based sealants. The concentration of other ions released from the sealants in the surrounding distilled water was also examined. At the initial stage, fluoride was rel...
