STRUCTURAL AND IONIC CONDUCTIVITYSTUDIES ONPLASTICIZED PAN-SODIUM FLUORIDE POLYMER ELECTROLYTES FOR ELECTROCHEMICAL CELL APPLICATIONS
Ion conducting gel polymer electrolytes based on poly acrylonitrle (PAN) complexed with different weight percent ratios of Sodium Fluoride (NaF) salt were prepared by using solution cast technique. Structural characterization was performed using X-ray diffraction (XRD) technique and Fourier transforms infrared (FTIR) spectroscope technique. From the X-rd results increase in amorphous phase with...
متن کاملComparison of Fluoride Uptake into Enamel from Sodium Fluoride Gel 0.05% Produced in Iran and Stannous Fluoride 0.4% Gel
Background & Aims: The present study compared fluoride uptake into enamel from sodium fluoride 0.05% gel and American Dental Association approved fluoride gel (Stannous fluoride 0.4% , Sultan Co.) when used on healthy enamel of the intact teeth. Methods: In an experimental study, 30 intact teeth extracted for orthodontic purposes were randomly assigned into two groups of 15 teeth. The teeth wer...
متن کاملEnhancement of sodium fluoride-induced cell death by centrifugal force.
As an initial step in the study of the influence of orthodontic force on cellular function in vitro, the effects of centrifugal force on the cytotoxicity induced by various apoptosis inducers were investigated. When human oral squamous cell carcinoma (HSC-2) and human promyelocytic leukemia (HL-60) cell lines were treated with increasing magnitudes of centrifugal force (evaluated by g-value), t...
متن کاملFluoride release from three glass ionomers after exposure to sodium fluoride and acidulated phosphate fluoride gels
BACKGROUND Glass ionomer (GI) restorations exposed to fluoride have the ability to slowly release fluoride. Therefore, the aim of this study was to investigate fluoride release from three GIs before and after exposure to sodium fluoride (NaF) and acidulated phosphate fluoride (APF). MATERIALS AND METHODS Fifteen disc-shaped samples (6 mm in diameter and 2 mm in thickness) from three GIs (Fuji...
