Abstract:
This study evaluated the effect of titanium tetrafluoride (TiF4) varnish on the development of dentin carious lesions. Bovine root dentin samples were treated for 6 h with: (A) 4% TiF4 varnish (2.45% F); (B) 5.42% sodium fluoride (NaF) varnish (2.45% F); (C) 2% chlorhexidine (CHX) gel – positive control; (D) placebo varnish; or (E) untreated – negative control (n = 4 × biological triplicate, n = 12). Treated dentin samples were exposed to human saliva mixed with McBain saliva (1:50) for the first 8 h in 24-well plates. Thereafter, the medium was removed, and McBain saliva containing 0.2% sucrose was applied for 16 h. From days 2 to 5, McBain saliva with sucrose was replaced daily (37°C, 5% CO2). The demineralization was measured using transverse microradiography, while the effect on biofilm was analyzed using viability, extracellular polysaccharide (EPS), and lactic acid production assays. The data were statistically analyzed (p < 0.05). All treatments (fluorides and CHX) significantly reduced the biofilm viability compared to placebo varnish and negative control. However, none of them was able to reduce the colony-forming unit counting for total microorganism, total streptococci, and Streptococcus mutans. NaF significantly reduced the number of Lactobacillus sp. compared to negative control. No effect was seen on lactic acid production neither on EPS synthesis, except that CHX significantly reduced the amount of insoluble EPS. Both fluorides were able to reduce dentin demineralization compared to placebo varnish and negative control; TiF4 had a better effect in reducing mineral loss and lesion depth than NaF. Therefore, TiF4 varnish has the best protective effect on dentin carious lesion formation using this model.

Abstract:
AbstractBackgroundNanosilver fluoride (NSF) was developed as an alternative in the prevention of dental caries.PurposeThe aim of this study was to test the remineralizing action of NSF on incipient enamel caries and its antimicrobial action on the acid production and adhesion of Streptococcus mutans.MethodsDeciduous enamel fragments were treated with sodium fluoride (NaF), NSF and deionized water. Microhardness, fluorescence spectroscopy and optical coherence tomography imaging were performed on each specimen before chemical caries induction, after caries induction and after 14 days of pH cycling. The treated enamel fragments were also placed into test tubes containing bacterial suspension and saliva. The pH readings and quantification of the adhered microorganisms to the dental enamel were determined. Analysis of variance, Kruskal-Wallis, Mann-Whitney, Tukey and mixed linear regression model were applied.ResultsNSF and NaF were effective in enamel remineralization, with a statistically significant difference (p<0.001) to deionized water, and they had no statistically significant difference between themselves (p>0.005). NSF had greater effectiveness compared to NaF in preventing decreases of pH and adhesion of S. mutans to the enamel surface, with statistically significant (p<0.001) differences.ConclusionNSF may be more effective than conventional fluorides in treating incipient caries lesions due to its remineralization and antibacterial actions.

Abstract:
Introduction. Consistency of fluoride excess in the human environment and professional contact with fluoride is an actual and underestimated problem. Fluoride ion is able to displace the hydroxyl group in calcium hydroxyapatites, forming stable crystals of mixed form of apatites, inducing bone pathology, fluorosis. Despite the high prevalence of fluorosis, there are only a few studies discussing the ability of fluoride ion to increase the level of genotoxic effects. At the same time, such studies are in high demand in connection with a direct correlation between genetic instability and the risk of carcinogenesis. Material and methods. A literature search was conducted according the following queries: “fluoride, fluoride ion, fluorides, DNA damage, genetic damage, genotoxicity.” The search was conducted on the databases PubMed, MEDLINE, Embase and Google Scholar for various articles (all publications until June 2018). All publications were analyzed and included in this review. Results.The present review examines the results of studies aimed at investigation of the ability of fluoride to induce DNA damage, published since the 50-s of 20th century to the present. The analyse of data about genotoxic and mutagenic properties of fluorine observed in In vitro and In vivo studies is provided. It is summarized that at concentrations of sodium fluoride in drinking water of more than 1 mM, fluoride ion has the ability to induce DNA damage and increase the frequency of clastogenic effects in humans and large monkeys. At the same time, for a significant increase in genotoxic effects in rodents, large concentrations of fluorides are required. The main hypotheses about the mechanisms of the fluoride genotoxic properties are described. Conclusion. Considering results published nowadays, it can be noted that fluoride ion obviously showes a number of genotoxic features and can have mutagenic properties in case of chronic and direct contact with cellular objects. It remains questionable issue about genotoxic risk accompanied human contact with fluoride compounds.
