      다국어 초록 (Multilingual Abstract)

      The purpose of this study were to measure the solubility of the stannous fluoride experimentally,to find a method for improving the solubility of the stannous fluoride,and to observe the effect of longterm storage of the variation of the concentration of fluoride in the stannous fluoride solutions.By adding such materials as antiseptics,dye,flavor,and tests to solution,the variation of the fluoride concentration was also observed.
      Ten groups of 0.4% stannous fluoride solutions to which glycerine,sodium chloride,chlorhexidine,dye,flavor,xylitol,and sorbitol were added were prepared.The measurements were carried out by direct calibration.
      The obtained results were as follows.
      1.Effect of adding glycerine as solvent:This solubility of the stannous fluoride increased in the case of adding glycerine.By increasing the glycerin concentration,the fluoride level in stannous fluoride solution also increased.
      2.Effect of adding sodium chloride and chlorhexidine.:Comparing to the case of pure water,low fluoride level was measured in case of adding sodium chlorid and high fluoride level was measured in case of adding chlorhexidine.
      3.Effect of adding erythrosin as dye and banna essence as flavor.:Adding erythrosin and banna essence didn't affect fluoride level.
      4.Effect of adding xylitol and sorbitol.:The effects of xylitol and sorbitol were nearly the same as the effect of adding erythrosin and banna essence.
