COMPARATIVE STUDY OF THE CYTOTOXICTY AND GENOTOXICITY OF SILVER ZEOLITE AND NANO SILVER

15# nanosilvehas significantly bateriostatic effect against Penicillium, The minimal inhibitory concentrations of 15# nana silve for inhabiting Penicillium is 1 mg/L. Through a comparative study of the bacteriostatic effect of different nanosilver and other bacteriostatic agents against Penicillium, it is found that the bacteriostatic effect of nanosilver against penicillium is very significantly better than lincomycin hydrochloride and streptomycin sulfate, in which, the bacteriostatic effect of nanosilver 14# nanosilve against penicillium is significantly better than 13# nanosilve, and 13# nanosilve is very significantly better than that of 15# nanosilve.It provides a new way for the prevention and control of Penicillium.

Clinical Relevance The new formulations of nano-silver fluoride caused less dentin staining than the already available commercial agents 35% silver fluoride and silver diamine fluoride at 30% and 38%. SUMMARY The objective of this study was to evaluate the dentin staining potential of nano-silver fluoride (NSF 600 and 1500 ppm) compared with the following commercially available cariostatic agents: Advantage Arrest (Elevate Oral Care, West Palm Beach, FL, USA), Riva Star (SDI, Victoria, Australia), and Cariestop (Biodinâmica, Paraná, Brazil). Seventy-five extracted human molars were sectioned at the cementoenamel junction, and the occlusal enamel was removed for exposure of coronary dentin. The samples were divided among the five agents tested (n=15). The dentin staining (ΔE/ΔL) was analyzed with a digital spectrophotometer (VITA Easyshade, VITA Zahnfabrik, Bad Säckingen, Germany) at three different time points (before application, after two weeks, and after four weeks). Photographic images were also performed. The Kruskal-Wallis and Mann-Whitney tests compared the mean ΔE and ΔL values between groups. The NSF 600 and 1500 ppm resulted in the smallest color change (ΔE=1.02 and 1.53) and dentin staining after four weeks (ΔL=−0.76 and −1.2). The new formulations differed significantly from the commercial cariostatic agents (p<0.001). NSF might be an alternative to silver diamine fluoride since it does not compromise esthetics.

Through a comparative study of the bacteriostatic effect of nanosilver of different species and concentrations against bacteria, it is found that nanosilver have significant bacteriostatic effect against bacteria. Bateriostatic effect of nanosilve 15# against B. thuringiensis is significantly better than E.coli, s. aureus and B. subtillis. The optimal concentrations of 15# for inhabiting E. coli, S. aureus, B. subtillis and B. thuringiensis respectively are: 20 mg/L, 10 mg/L, 1 mg/L, 40 mg/L. nanosilvers of 13#, 14# and 15# have no significant differences in the bacteriostatic effect against E.coli, but are all significantly better than the bacteriostats of lincomycin hydrochloride and streptomycin sulfate. Antibacterial principle of nanosilver is damaging the cell membrane permeability.
