Influence of growth mode and sucrose on susceptibility of Streptococcus sanguis to amine fluorides and amine fluoride-inorganic fluoride combinations.
نویسندگان
چکیده
This study evaluated the susceptibility to amine fluorides (AmFs) of planktonic and biofilm cultures of Streptococcus sanguis grown with and without sucrose. Cultures were incubated with AmFs (250 mg of fluoride liter-1) for 1 min. The susceptibility of biofilms was less than that of the planktonic form and was further decreased by growth in the presence of sucrose.

Effects of different kinds of fluorides on enolase and ATPase activity of a fluoride-sensitive and fluoride-resistant Streptococcus mutans strain.
Enolase and ATPase are sensitive to fluoride. It is unclear whether this sensitivity differs for F-sensitive and F-resistant cells or for different types of fluoride. Permeabilized cells of the fluoride-sensitive strain Streptococcus mutans C180-2 and its fluoride-resistant mutant strain C180-2 FR were preincubated at pH 7 or 4 with NaF, the amine fluorides Olaflur and Dectaflur and amine chlor...

UNLABELLED Fluorides play a significant role in the promotion of oral health, fostering remineralization, inhibiting demineralization processes in the enamel, and having antibacterial activity. The effects of fluorides are mostly exerted by their topical effect. The beneficial effect of amine fluorides (AmF) on caries and dental plaque reduction has been known for a long time. The caries reduci...

Abstract Background & Aim: Oral diseases, especially dental caries, are still prevalent in the most developing countries which cost a lot for patients and the health care system. One of the most important ways to reduce costs is to prevent caries. Therefore, the aim of this study was to evaluate the effect of chlorhexidine and fluoride mouthwashes in comparison with Nanosil D1+F combined mouthw...

The title compound, (C(6)H(21)N(4))[TiF(6)]F, was synthesized by the reaction of TiO(2), tris-(2-amino-ethyl)amine, HF and ethanol at 463 K in a microwave oven. The crystal structure consists of two crystallographically independent [TiF(6)](2-) anions, two fluoride anions and two triply-protonated tris-(2-amino-ethyl)-amine cations. The Ti atoms are coordinated by six F atoms within slightly di...

Topical fluoride therapy (TFT) in the form of toothpastes, mouthrinses, varnishes and gels are effective caries preventive measures. Different fluoride compounds, different vehicles, and vastly different concentrations have been used with different frequencies and durations of application. These variables can influence the clinical outcome with respect to caries prevention and management. The e...
